The technical field

The present invention relates to the liquid crystal display panel and the LCD display device. In particular, the present invention relates to the liquid crystal display panel and the LCD display device in which one (1) item image is divided into multiple domains, so that the molecules of a liquid crystal can navigate in multiple directions.

The level of technology

In recent years, the liquid crystal display devices are rapidly gaining popularity as an alternative cathode ray tubes (CRT). Such liquid crystal display devices are used in a wide variety of devices, such as TVs, monitors and mobile phones, thanks to its characteristics, such as energy saving, reduced thickness and low weight.

In particular, recently we developed the so-called mobile device equipped with (i) the battery is running as a power source and has limited capacity, and (ii) liquid crystal display device functioning as a means of display.

In this mobile device battery with limited capacity, is used as a power source. So for longer periods of time of continuous work of the mobile device special attention is paid to reducing the energy consumption of the LCD display device.

In depending on the circumstances, attention is paid to the method of providing low-power liquid-crystal display device due to (i) increase relative aperture and transmittance of the LCD display panel provided in liquid crystal the display device, and (ii) reduce the amount of light backlight accordingly.

Liquid crystal display device, the most widespread in the past, is an LCD display device TN (twisted nematic) type, which uses the molecules of a liquid crystal with a positive dielectric anisotropy. However, the problem this LCD display device TN-type is that the image quality, such as contrast and color tone, significantly reduced while watching the LCD display device under oblique angles top, bottom, left and right, compared with front supervision.

Thus, the liquid crystal display device TN-type has a high dependence of the quality of the image from the angles of observation and therefore unusable in the case when the liquid crystal display device is expected to be seen in a different direction from the front.

Liquid crystal display device type IPS (in-plane switching) LCD display device type MVA (multi-domain vertical alignment) is known as an LCD display device in which such dependence image quality from the corners monitoring improved.

According liquid crystal display device IPS-type, the dependence of the quality of the image from the viewing angles are quite improved, because the orientation of the liquid crystal molecules in a plane parallel to the substrate surface, change according to the supplied voltage. However, liquid crystal display device IPS-type has the following problem: on the side of the substrate TFT provided with two electrodes to control, for each element of the image, the liquid crystal molecules in a plane parallel to the substrate surface, and over two electrodes, there are areas where management of liquid crystal molecules is impossible. This leads to a significant decrease relative aperture.

On the other hand, according to the LCD display device MVA-type, at least one of the two substrates, between which laid the liquid crystal layer has on its side in contact with the liquid crystal layer, (i) transparent electrode with the tabs, which function as a means of orientation separation and/or (ii) transparent electrode crotchless that function as a means of orientation separation. Because of this they are transparent(YM) electrode(s) each element of the image is the area where the molecules of the liquid crystal are oriented in the appropriate different directions that allows to provide an overview of the wide angle.

However, in recent years the definition liquid crystal display devices increases and the size of one (1) item image tends to decrease. In this picture element is provided with a transparent electrode, structured to owning the bumps and cuts, which function as a means of orientation separation. Depending on the circumstances of the effective aperture ratio of one (1) item image tends to decrease.

In each of the elements of the image disorder in the orientation of the liquid crystal molecules (hereinafter sometimes referred to as simply “disorderly orientation”) occur in a stepwise parts, such as marginal parts of the image element in the area where ensured black matrix, and in sections pin holes. In particular, in the case when the effective aperture ratio of one (1) item image a little, as described above, the ratio of the square where the disorder orientation, and the total area of each element of the image increases.

As a result, there are differences in brightness between the elements of the image due to uneven disorder orientation, due to changes completed thin structures (i.e. production changes). Differences in brightness are seen as blurring the image, and this reduces the quality of the display the LCD display device.

Consider the method of suppression of reducing display quality due to lack of clarity of the image. Thus, (i) it is possible to apply a transparent electrode, structured for additional stabilisation of the orientation of the liquid crystal molecules in the area where there is disorder orientation; or (ii) an area where there is a blurred image, you can escape from the world.

For example, in patent literature disclosed 1 liquid crystal display device with vertical alignment that includes electrodes image elements, each of which has a shape, formed by three polygonal parts of a transparent electrode, which are connected in series.

Fig. 12 illustrates the schematic configuration of the electrode of image element, part of the LCD display device with vertical alignment.

Electrode 348 picture element has a form, formed by three polygonal pieces transparent electrode (hereinafter referred to as “the electrodes 348u subitems image”), connected to each other (see Fig. 12). Each electrode 348 element of the image is provided in the relevant field 349 sub-element of the image (see the shaded region in Fig. 12).

Note that each of the electrodes 348u subitems picture has the shape of a polygon, the outer edge or the perimeter of which, essentially, is separated from the centre electrode 348u subitem image so that the molecules of the liquid crystal are guided essentially radial above the electrode 348u subitem image.

Electrodes 348 image elements is provided in the matrix on the top layer formed on the substrate active matrix (not shown). Each of the electrodes 348 elements of the image corresponds to any of the colors of R (red), G (green) and B (blue), i.e. each of the electrodes 348 items image provided converted to any of the color filters 205R, 205G and 205B, (i) which is provided on the opposite substrate, addressed to the substrate active matrix, and (ii) each of which has essentially rectangular shape.

According to Fig. 12 each of the electrodes 348 image elements has a wire that is the section 348c connection, connected to one of the TFD (thin film diode) 320. Section 348c connection is made of material such as ITO (indium oxide-tin), which is the same as the electrode material 348 image element.

Section 348c connection runs from the perimeter of the electrode 348u subitem image below of all in the area of 349 subitem image, contact hole 346. Electrodes 348 image elements belonging to the same column, connected to a single line 314 data in the provisions of the relevant contact holes 346 through appropriate TFD 320.

While the electrodes 348 image elements belonging to the same string that is converted to a single line 214 scan (depicted by dashed lines in Fig. 12).

In particular, the line 214 scan is provided on the opposite substrate, and the aperture (holes) 214a formed in each line 214 scan provisions, essentially, the relevant centres of the respective electrodes 348u subitems image. When voltage is applied between the substrate active matrix, and the opposite substrate created an inclined electric field, in every part where the aperture 214a coincides with the electrode 348u subitem image, due to the interaction between aperture and 214a electrode 348u subitem image. This configuration allows you to control the direction of the tilt of the liquid crystal molecules.

Thus, you can control the liquid crystal molecules, directing them to radial, in accordance with the voltage applied between the substrate active matrix, and the opposite substrate. This allows forming region, in each of which the molecules of the liquid crystal radially oriented.

The covering layer is contact openings 346, each of which is an aperture, which, in essence, a round shape when viewed from the top of the LCD display device. Section 348c connection of each of the electrodes 348 image elements is electrically connected to TFD 320 and line 314 data through a pin hole 346.

In the LCD display device with vertical alignment with this configuration top layer, the molecules of the liquid crystal vertically oriented in the initial state of orientation liquid crystals, which are not applied voltage. However the molecules of a liquid crystal, located on pin holes are affected inclined planes pin holes that have stepped part. So disorder orientation of the liquid crystal arise in the provisions on pin holes.

Depending on the circumstances in the case when, for example, pin holes 346 ensured in an effective display area of the electrode 348 picture element, i.e. in the provisions corresponding to the electrodes 348u subitems image or near provisions, the molecules of the liquid crystal in the effective area display exposed to negative influence of neuporyadochennost orientation of the liquid crystal molecules that occur in the provisions of the corresponding pin holes 346, which consequently leads to the problem of image quality, such as non-uniformity of the display.

According configuration disclosed in patent literature 1, in order to avoid such problems in the quality of images, each of pin holes 346 secured in position, which is in the field of image element, but does not match any of the electrodes 348 image elements in the area of 349 sub-elements of the image (see Fig. 12). In particular, each of pin holes 346 provided in the regulations, the most remote from an electrode 348 picture element in the area of 349 sub-element of the image (i.e. in the corner of the field 349 subitem image).

According to the configuration, you can make contact hole 346 was located away from the electrode 348u subitem image (corresponding effective display area). Therefore the molecules of a liquid crystal in an effective display area, which complies with the provisions of electrodes 348u subitems images and serves as a section of the display is exposed to the strong influence of neuporyadochennost orientation arising in the provisions of pin holes 346.

Patent references 1 describes that with this configuration, you can implement the LCD display device that can (i) to suppress the occurrence of irregularity orientation of the liquid crystal molecules in effective display area and (ii) to display the image with high quality.

Patent literature 1 also describes that as pin hole 346 provided in a position that does not match the electrode 348 picture element, you can prevent the reduction of the relative aperture.

Summary of the invention

Technical problem

However, according to the configuration disclosed in patent literature 1, pin hole 346 should be located away from the electrodes 348u subitems the images that match the effective display area (see Fig. 12). It is therefore difficult to provide a large area for electrodes 348u subitems of the image (i.e. the effective display area).

In General, pin hole is formed tapering forward, taking into account the subsequent processes. In this case, pin hole has a part tapering forward, i.e. an inclined area.

Pin hole with such inclined region, may cause the disorder orientation of the liquid crystal molecules. In the case when the area affected disorder orientation, shielded from the light, resulting in disorder orientation is not observed, relative aperture and transmittance of the LCD display panel and LCD display device decrease.

So with this configuration, it is difficult to ensure the LCD display panel and LCD display device with high relative aperture and high transmittance.

The present invention is made in view of this problem and its task is to ensure (i) LCD panel display, capable of high-quality display and high relative aperture and high transmittance, and (ii) liquid crystal display device capable of high-quality display with low power consumption.

Solution

To solve this problem the LCD display panel of the present invention includes the first insulating base; the second insulating base; liquid-crystal layer located between the first insulating substrate and the second insulating substrate, demonstrating negative dielectric anisotropy; many elements of the image, and LCD panel display are arranged so that one substrate of the first and second insulating substrates has on its side in contact with the liquid crystal layer, the common electrode with the tabs and/or cutouts that function as a means of orientation separation; another substrate has a line signal scan line data signal and electrodes image elements, secured on her side in contact with the liquid crystal layer; each of electrodes elements in the picture section has deepened and extended partition; electrodes image elements is electrically connected to the corresponding electrode flow of active elements, which provided for the electrode control elements of the image, through the appropriate holes provided in the insulating layer; electrodes image elements other substrates are located closer to the liquid crystal layer than the insulating layer; and at least part of serving sections electrode item image coincides with a through hole, if to look from above LCD panel display so that the image elements identical to each other in orientational structure of the liquid crystal molecules oriented in different directions in the liquid crystal layer.

Such a through hole, in General, taper forward, taking into account the subsequent processes. In this case, through hole has stepped part that has an inclined area.

Through hole, an inclined area may cause the disorder orientation of the liquid crystal molecules.

The traditional approach involves the application of (i) the configuration in which the area which formed through hole, must be kept clear of the field (the corresponding effective display area, where the formed electrode picture element, or (ii) configuration, in which a through hole is formed, basically, in the centre electrode element of the image, the corresponding effective display area. According to the traditional configurations, it is difficult (i) to provide more effective display area and (ii) to reduce the effect of liquid crystal molecules suffering from the disorder orientation due through holes on other molecules of the liquid crystal, which should be oriented in predefined directions to the effective display area.

In the area which is formed through hole, the chaotic nature of the orientation of the liquid crystal molecules occurs due form tilted area through holes. The impact of this disorder orientation cannot be neglected in the display panel, for example in the LCD panel, displaying high definition, in which the size of one (1) item image is small. In particular, defective display, such as blurred image, may be due to uneven disorder orientation, due to (i) changes in finished thin structures through holes and/or (ii) a slight difference in the shape of a recumbent region caused by the production process. In addition, the area where formed through hole, i.e., suffering from the disorder orientation affects the orientation of the liquid crystal molecules around the area. This increases the probability of defective display, such as lack of clarity in the image.

According to configuration of the present invention, at least, part of serving sections electrode item image coincides with a through hole, if you look from the top of the LCD display panel.

According to the configuration, you can reduce the effect of liquid crystal molecules suffering from the disorder orientation due to a through hole, on the other molecules of the liquid crystal, which should be oriented in predefined areas in effective display area. Consequently, you can prevent defective display, such as lack of clarity in the image.

Therefore, we can ensure LCD panel display, capable of high-quality display and high relative aperture and high transmittance.

Note that through hole covers not only significant connecting section of the electrode flow of the active element, and of the electrode element of the image, but also the area (inclined region) inclined part of the insulation layer.

To solve this problem the LCD display device present invention includes liquid crystal display panel of the present invention.

As described above, the LCD display panel of the present invention are arranged so that one substrate of the first and second insulating substrates has on its side in contact with the liquid crystal layer, the common electrode with tabs and/or cutouts that function as a means of orientation separation; another substrate has a line signal scan line data signal and electrodes image elements, secured on her side in contact with the liquid crystal layer; each of the electrodes elements the image has a section deepening and protruding section; electrodes image elements is electrically connected to the corresponding electrode flow of active elements, which provided for the electrode control elements of the image, through the appropriate holes provided in the insulating layer; electrodes image elements other substrates are located closer to the liquid crystal layer than the insulating layer; and at least part of serving sections electrode item image coincides with a through hole, when viewed from the top LCD panel the image so that the image elements identical to each other in orientational structure of the liquid crystal molecules oriented in different directions in the liquid crystal layer.

As described above, liquid crystal display device present invention includes liquid crystal display panel of the present invention.

Therefore, we can ensure LCD panel display, capable of high-quality display and high relative aperture and high transmittance. In addition, the LCD display device, equipped with LCD display panel can reduce the brightness of the backlight and may, respectively, to display with low power consumption.

In the following description will be reviewed, with reference to figure 2, the configuration of the liquid crystal device 13 display type MVA, including LCD panel 12 display type MVA of the present invention.

Figure 2 illustrates the schematic configuration of the liquid crystal device 13 display in accordance with the embodiment of the present invention.

LCD panel 12 display includes (i) matrix substrate 1, serves as the first of the substrate (the first insulating substrate), (ii) the opposite substrate 5, serves as the second of the substrate (the second insulating substrate), and (iii) liquid crystal layer 9, which was laid between the matrix substrate 1 and opposite substrate 5 and made of liquid crystal material with negative dielectric anisotropy (see Fig. 2).

Matrix pad 1 includes (i) base glass 2, which functions as an insulating substrate, (ii) layer forming elements TFT (not shown), which is formed on the glass substrate 2 and element contains TFT and wire, electrically connected to the element TFT, (iii) insulating interlayer film 3 (insulating layer), formed in a layer of forming elements TFT, and (iv) the electrode 4 image element, electrically connected to the electrode flow element TFT through a pin hole (not shown), which formed in insulating interlayer film 3.

Polarizing plate 10 provided on the side of the matrix substrate 1, and the side opposite side in contact with the liquid crystal layer 9. Polarizing plate 11 provided on the opposite side of the substrate 5, the side opposite side in contact with the liquid crystal layer 9.

Option 1 exercise, for example, a layer of color filters (not shown), with any of the red, green, and blue colors, ensured between the glass substrate 6 and a counter-electrode 7 for each of the electrodes 4 image elements, which provided for relevant elements of the image matrix substrate 1. However, it should be noted that option 1 exercise is not limited, and the layers of color filters can be ensured on the side of the matrix substrate 1 (this configuration is called the configuration COA (a color filter on the matrix)).

In the following description will be considered in detail the configuration of matrix substrate 1 provided in liquid crystal device 13 display, with reference to Fig. 3.

Fig. 3 shows a schematic configuration matrix substrate 1, part liquid crystal devices 13 display, in accordance with the embodiment of the present invention.

Matrix pad 1 has (i) region R1 display, in which the elements PIX image linked in the image matrix, (ii) diagram 19 excitation line data signal and (iii) the scheme 20 excitation line signal scanning (see Fig. 3). Note that the diagram 19 excitation line signal data and diagram 20 excitation line signal scan served on the region R1 display the signals required for the implementation of the displayed image.

In version 1 implementation (i) diagram 19 excitation line signal data and diagram 20 excitation line signal scan, which are located on the peripheral area R1 display, and (ii) items 16 TFT provided for the respective elements PIX images R1 display, integrally formed to reduce outdoor frame liquid crystal devices 13 display. However, it should be noted that option 1 exercise is not limited. In the case of a large liquid crystal display device for which the reduction of the area of the outer frame does not play a role, the scheme 19 excitation line signal data and diagram 20 excitation line signal scanning can be achieved externally through the detail, such as flexible printed circuit Board.

When the semiconductor layer (semiconductor layer 18 Fig. 1) item 16 TFT is amorphous semiconductor layer, preferably, only the schema 20 excitation line signal and scan items 16 TFT were integrally formed.

In the area of R1 display matrix substrate 1 provided many lines (SL1, SL2, and so on) signal data and multiple lines (GL1, GL2, etc) signal scan, and elements of 16 TFT provided in the corresponding crossing points can data signal and the signal lines scanning (see Fig. 3).

Serial signals scanning high levels schema 20 excitation line signal scanning to multiple lines (GL1, GL2, etc) signal scan with the following items are included 16 TFT connected to the multitude of lines signal scan through signals scanning, image signals coming from the schema 19 excitation line data signal to the electrodes of the source elements TFT 16, connected to multiple lines (SL1, SL2, etc) data signal, proceed to the electrodes image elements, connected to the electrodes of the flow of relevant elements 16 TFT.

Figure 3 LCD capacitor CL specifies the capacitor formed by (i) electrode image element, connected to the electrode flow item 16 TFT, (ii) liquid crystal layer and (iii) counter-electrode. In addition, the storage capacitor Cs indicates condenser, educated (i) the counter-electrode mass storage capacitor connected to the electrode flow item 16 TFT, (ii) insulating interlayer film and (iii) electrode mass storage capacitor connected to a line of storage capacitors. Note that figure 3 many lines of storage capacitors are not shown that runs parallel to the multitude of lines (GL1, GL2, etc) signal scanning.

In version 1 implementation, the storage capacitor Cs is provided for each of the elements in the picture. However, it should be noted that option 1 exercise is not limited, and the storage capacitor Cs, if necessary, can be omitted.

In the following description will be considered in detail the electrode 4 item images, provided in the matrix substrate 1, with reference to Fig. 1.

Fig. 1 illustrates the schematic form of the electrode 4 image element, included in the matrix substrate 1 liquid crystal devices 13 display, in accordance with option 1 implementation.

In liquid crystal device 13 display option 1 exercise, one (1) pixel having, essentially, a square shape, made of three elements of the image, i.e. the red image element, green image element and blue image element. Each of the three elements of the image has essentially rectangular shape (see Fig. 1).

She section 4a of the electrode 4 image element, electrically connected to the electrode flow item 16 TFT through a pin hole 17 (through hole), formed in insulating interlayer film. Thus, pin hole 17 formed over the counter-electrode 15 storage capacitor (described below). In General, pin hole 17 formed tapering forward, taking into account the subsequent processes. In this case, pin hole 17) has stepped part that has an inclined area.

Pin hole 17, shown in Fig. 1, includes not only the essential connecting section of the electrode flow item 16 TFT and electrode 4 elements of image, but also the area (inclined region) inclined part insulating interlayer film.

Note that in version 1 implementation, pin hole 17 is rectangular when viewed from above the liquid crystal display panel (see Fig. 1). However, option 1 exercise is not limited with this, and pin hole 17 may take the form, for example elliptical or circular shape.

In the area where the generated pin hole 17, the chaotic nature of the orientation of the liquid crystal molecules occurs as a result of stepped form side and effects of this disorder orientation cannot be neglected in display devices, such as liquid crystal display high-definition, in which the size of one (1) item image is small. In particular, changes in finished thin structures pin holes 17 cause differences in disorder orientation of the liquid crystal molecules, which leads to defective display, such as lack of clarity in the image.

In addition, the area where the generated pin hole 17, i.e. the region, suffering from the disorder orientation affects the orientation of the liquid crystal molecules around the area. This increases the probability of defective display, such as lack of clarity in the image.

According matrix substrate 1 shown in Fig. 1 at least part of the serving of section 4a of the electrode 4 item image coincides with the contact hole 17, when seen from the top of the LCD display panel.

According to the configuration, you can reduce the effect of liquid crystal molecules suffering from the disorder orientation due to contact openings 17 other molecules of the liquid crystal, which should be oriented in predefined areas in effective display area. Accordingly, you can suppress the defective display, such as a blurred image.

Note that the electrode 4 elements of the image can be made of electrically conductive material, such as ITO (indium oxide-tin) or IZO (indium oxide-zinc). Note that the electrode 4 image elements can be structured by (i) the formation of a film of resist having a pre-defined structure, on the ITO film or film IZO and then (ii) etching of the ITO film or film IZO using film resist as a mask.

As described above, in liquid crystal device 13 display at least part of the serving of section 4a of the electrode 4 item image coincides with the contact hole 17, having inclined the region, if seen from the top of the LCD display panel.

Thanks to such configuration can reduce the effect of liquid crystal molecules suffering from the disorder orientation due to contact openings 17, having inclined the region, and to other molecules of the liquid crystal, which should be oriented in predefined areas in the effective area display. Accordingly, you can optionally suppress defective display, such as a blurred image.

The electrode 4 item image liquid crystal devices 13 display has an in-depth section 4b formed by cutting electrode 4 elements of the image, in essence, triangular in shape so that the slope of the deep section 4b is essentially consistent with the slopes (formed directions) sections 8 ledge, which is provided on the opposite side of the substrate 5 and function as a means of orientation separation (see Fig. 1).

Note that the advanced section 4b of the electrode 4 image element is made in such a form that she section 4a item 4 image immediately adjacent to drilldown section 4b can be located (i.e. partially fit) in depth section 4b.

As described above, an in-depth section 4b of the electrode 4 image element operates as a means of orientation separation and allows serving of section 4a item 4 image immediately adjacent to drilldown section 4b, be placed in it.

According to the configuration can be used effectively in depth section 4b of the electrode 4 elements of the image that cannot be used as an effective display area, which allows to increase the ratio of the effective aperture area. This allows the liquid crystal device 13 display with high relative aperture and high transmittance.

Note that a specific example, in which the ratio of the effective aperture space increased compared with traditional configuration, will be described below.

Option 1 exercise, each serving sections 4a and depth of section 4b of the electrode 4 elements of the image has essentially triangular shape. However, it should be noted that the form of each of serving sections 4a and depth section 4b is not limited with this, provided that the form allows serving of section 4a to be in depth section 4b.

Option 1 exercise, if you look from the top of the LCD panel display, at least part of the deep section 4b of the electrode 4 elements of the image is made, essentially parallel sections 8 ledge, which is provided on the opposite side of the substrate 5 and function as a means of orientation separation. However, it should be noted that option 1 exercise is not limited with this, and in-depth section 4b can be made in any form, provided that she section 4a may be placed in depth section 4b.

Option 1 exercise, pin hole 17, which formed coinciding with acting section 4a, if seen from the top of the LCD panel display, also coincides with the section of forming a storage capacitor Cs (described below), if seen from the top of the LCD display panel (see Fig. 1).

Section forming a storage capacitor Cs electrode made of 14 storage capacitor insulating layer (not shown) and counter-electrode 15 storage capacitor. Electrode 14 storage capacitor (i) formed in a layer, where he formed a line (GLn-1, GLn and so on) signal scan, (ii) is connected to the corresponding one of the lines (CSn-2, CSn-1, CSn, etc.) of storage capacitors, and (iii) reaches a depth of section 4b of the neighboring electrode 4 image element. The counter-electrode 15 storage capacitor (i) formed in a layer, where he formed a line (SLm-1, SLm and so on) signal data, (ii) is connected to the electrode flow item 16 TFT and (iii) addressed to the electrode 14 storage capacitor through the insulating layer.

According configuration, contact hole 17, which causes the disorder orientation of the liquid crystal molecules formed so that when viewed from the top of the LCD panel will display at least part of pin holes 17 matches a section forming a storage capacitor Cs, which has metallic layer and does not transmit light. This allows the liquid crystal device 13 display, which has a high relative aperture and high transmittance.

Note that each of the lines (GLn-1, GLn and so on) signal scan lines (CSn-2, CSn-1, CSn, etc.) storage capacitors, lines (SLm-1, SLm, etc.) data signal electrode 14 storage capacitor and counter-electrode 15 storage capacitor may be formed using (i) of the item selected from a group that includes Mo, Ta, W, Ti, Al, Cu, Cr, Nd, or (ii) material alloy or material compounds containing mainly any of the items. However, it should be noted that option 1 exercise is not limited.

The electrode 4 image element has a section 4c of the cut, which are cut in two corners at the end of the electrode 4 elements of the image, and at the end to provide adequate one of the lines (CSn-2, CSn-1, CSn, etc.) a storage capacitor (see Fig. 1). Each section 4c cut formed, basically, in accordance with tilt (formed by the direction) of section 8 of the ledge, which is provided on the opposite side of the substrate 5 and functions as a means of orientation separation.

Therefore, section 4c of the cut function as a means of orientation separation.

If seen from the top of the LCD panel display line (GLn-1, GLn and so on) signal scan, which is provided on a matrix substrate 1 overlap with sections 8 ledge that provided on the opposite side of the substrate 5 and function as a means of orientation separation (see Fig. 1).

If seen from the top of the LCD panel display, the electrode 4 picture element (i) does not match the first line of the signal scan (which is one from lines (GLn-1, GLn and so on) signal scan), through which the signal scan goes on item 16 TFT, which is electrically connected electrode 4 elements of the image, but (ii) coincides with the second line of the signal scan (which is different from lines (GLn-1, GLn and so on) signal scan), which is adjacent to the first line of the signal scanning.

As described above, in option 1 exercise, if you look from the top of the LCD panel display, section 4c cut electrode 4 item image formed essentially parallel sections 8 ledge, which is provided on the side opposite substrate 5 and function as a means of orientation separation. However, it should be noted that option 1 exercise is not limited. In the following description will be reviewed, with reference to Fig. 4, a concrete example, in which the ratio of the effective aperture space increased compared with traditional configuration.

In Fig. 4 shows explaining the difference in the ratio of the effective aperture space between (i) traditional matrix substrate in which the electrode image element has no depth of the section in which is located serving section, and (ii) a matrix substrate in which the electrode image element has a thrust section and in-depth section, which can be located serving section.

Fig. 4(a) illustrates the schematic form of the electrode 104 item images, provided in the traditional matrix substrate 100. Fig. 4(b) illustrates the schematic form of the electrode 4 item images, provided in the matrix substrate 1b liquid crystal display devices, in accordance with another embodiment of the present invention, which will be described in detail under option 4 implementation.

Electrode 104 item images, provided in the traditional matrix substrate 100, has no depth of the section in which is located serving section (see Fig. 4(a)).

Therefore, around the area where the generated pin hole 117, easily occurs disorder orientation of the liquid crystal molecules, and, accordingly, uneven changes of finished thin structures arising in the production process, it is easy to see as a blurred image.

In when each element of the image of the traditional matrix substrate 100 has a size 63,5 microns longitudinal length and to 190.5 microns cross-length, the ratio of the effective aperture area is 31,6%, which is the ratio of (i) the area of image element, except (a) areas where formed section, no light, for example the metal part, and (b) of the region where he formed a means of orientation separation, and (ii) the total area of the image element. On the other hand, in the matrix substrate 1b, shown in Fig. 4(b), which has the image elements, each of which has the same size as the size of the item image shown in Fig. 4(a), the ratio of the effective aperture area is 34,9%. The fact that the electrode 4 image element has a thrust section 4a and depth section 4b, which can be located serving section 4a.

Thus, when you use the shape of the electrode 4 image element, included in the matrix substrate 1b, shown in Fig. 4(b), the ratio of the effective aperture area is increased by 3.3% in each picture element, i.e. increases, essentially, 10% in one (1) pixel compared with traditional configuration shown in Fig. 4(a).

Note that the electrode 104 item image shown in Fig. 4(a), has a section 104a and 104b cut, section 108 of the ledge, the electrode 114 storage capacitor, a counter-electrode 115 storage capacitor element 116 TFT and semiconductor layer 118, corresponding functions are similar to the functions of the relevant parts shown in Fig. 1. So the descriptions of these details are omitted here.

[Option 2 of implementation]

In the following description will be presented with the option of 2 the implementation of the present invention with reference to Fig. 5. Option 2 implementation differs from option 1 exercise that escape electrode 21 provided over the corresponding one of the lines (GLn-1, GLn and so on) signal scan for escaping the electric field lines signal scanning. Other configuration options 2 implementation is identical to the configuration option 1 implementation. For ease of explanation, the same reference positions are assigned to elements that have the same functions as the constituent elements shown on the drawings of option 1 exercise, and descriptions of such constituent elements are omitted here. Fig. 5 illustrates the schematic form of the electrode 4 item images, provided in the matrix substrate 1a liquid crystal display devices, in accordance with option 2 of implementation.

In Fig. 5 she section 4a of the electrode 4 item image provided so that is adjacent to drilldown section 4b neighboring electrode 4 elements of the image, according to the configuration shown in Fig. 1.

In the LCD display device high definition, using this arrangement, the provision which must be provided in-depth section 4b serving as a means of orientation division, is limited. Depending on the circumstances, an in-depth section 4b can be formed over the corresponding one of the lines (GLn-1, GLn and so on) signal scan, and line signal scan can be partially open (see Fig. 5).

According to the configuration in which there is no escape electrode 21 near each of the lines (GLn-1, GLn and so on) signal scan, and line signal scan partially open, impurity ions trapped in exposed parts during the period of retention voltage (when electric potential is low served on line signal scan), and the part where there capture impurity ions become singularities. Such singularities cause defective orientation of the liquid crystal, which leads to defective display in the LCD display device.

As described above, when provided shielding electrode 21, you can escape the electric field lines (GLn-1, GLn and so on) signal scanning. This allows to counteract defective display LCD display device.

[Option 3 implementation]

in the following description will be presented with the option of 3 implementation of the present invention with reference to Fig. 6. Option 3 implementation differs from option 2 realization of the fact that the counter-electrode 7 the opposite substrate 5, in addition to section 8 of the ledge, provided section 8a of the tab (the second shoulder), which serves as a means of orientation separation, so that, when seen from the top of the LCD panel display, section 8a of the same ledge with the upper area of the contact hole 17 (i.e. end part pin holes 17)provided in the matrix substrate 1a. Other configuration option 3 implementation is identical to the configuration options for the implementation of 1 and 2. For ease of explanation, the same reference positions are assigned to elements that have the same functions as components shown on the drawings variants of implementation 1 and 2, and descriptions of such constituent elements are omitted here.

Fig. 6 illustrates (i) schematic form electrode 4 image element provided in the matrix substrate 1a liquid crystal display devices, according to option 3 implementation and (ii) the structure of sections 8 and 8a of the ledge, secured, as a means of orientation of separation, on the counter-electrode 7 the opposite substrate 5. If seen from the top of the LCD panel display, the upper region of the contact 17 holes provided in the matrix substrate 1a, i.e. the part of the contact hole 17, and the part is located near the screening electrode 21, coincides with section 8a of the ledge, which is provided by the counter-electrode 7 the opposite substrate 5 and functions as a means of orientation separation (see Fig. 6).

In accordance with the above configuration in which a section 8a of the ledge serves as a means of orientation separation located so as to coincide with the upper region contact openings 17, i.e. part of pin holes 17 and part is located near the screening electrode 21, you can control the liquid crystal molecules so that they consistently oriented along sections 8 and 8a of the ledge, which ensured, as a means orientation of separation, on the opposite substrate 5.

This gives the opportunity to quell the disorder orientation of the liquid crystal molecules around the pin holes 17 and suppress irregular disorder orientation, the production-related changes of matrix substrate 1a and opposite substrate 5. According configuration, it enables to ensure the LCD display device that can effectively suppress the decline in the quality of the display, such as a blurred image. Note that adequate results can be achieved even if the counter-electrode 7 the opposite substrate 5 ensured section 8a of the ledge, as an aid orientation of separation.

Under option 3 implementation, each section 8 of the ledge and section 8a of the ledge made of photosensitive resist having a high light transmittance in the visible region, and formed so as to have in advance a certain form. However, note that option 3 implementation is not limited.

Under option 3 implementation, section 8a of the ledge is provided on the opposite side of the substrate 5. However, note that option 3 implementation is not limited to, section 8a of the ledge can be provided on the side of the matrix substrate 1a.

[Option 4 implementation]

In the following description will be presented with the option of 4 implementation of the present invention with reference to Fig. 7. Option 4 implementation differs from option 3 implementation the fact that an aid 4d orientation division (second section of the neckline) is provided at the top of the V-shaped depth section 4b of the electrode 4 image element. Other configuration options exercise of 4 identical configurations options 1-3 implementation. For ease of explanation, the same reference positions are assigned to elements that have the same functions as components shown on the drawings options 1-3 implementation, and descriptions of such constituent elements are omitted here.

Adjuvant 4d orientation of separation is provided at the top of the V-shaped depth section 4b of the electrode 4 elements of the image (see Fig. 7). By providing AIDS 4d orientation of separation line (GLn-1, GLn and so on) signal scan partially open. In this configuration, it is preferable to provide shielding electrode 21 (as described under option 2 exercise) to cover each of the partially open parts of lines (GLn-1, GLn and so on) signal scanning.

According to the configuration, you can implement improved management orientation of the liquid crystal molecules near the top of the V-shaped depth section 4b of the electrode 4 elements of the image, and in the summit provided an aid 4d orientation of separation. This gives the ability to control the liquid crystal molecules for their more efficient orientation.

This helps to ensure the LCD display device that can effectively suppress the decline in the quality of the display, such as a blurred image.

[Option 5 implementation]

In the following description will be reviewed version 5 implementation of the present invention with reference to Fig. 8. Option 5 implementation differs from the options 1-4 implementation of that column spacer 22 ensured between two adjacent elements of the image, i.e. the middle area between sections 4c cut corresponding two neighboring electrodes 4 image elements. Note that the column spacer 22 provided on the opposite side of the substrate 5 and serves to maintain a constant thickness of the cell between multi substrate 1 and opposite substrate 5. Other configuration option 5 implementation is identical to the configuration options 1-4 implementation. For ease of explanation, the same reference positions are assigned to elements that have the same functions as components shown on the drawings variants 1-4 implementation, and descriptions of such constituent elements are omitted here.

Fig. 8 illustrates (i) schematic form of the electrode 4 item image provided in the matrix substrate 1a liquid crystal display devices, in accordance with version 5 implementation, and (ii) the structure of the bar spacers 22 provided on the counter-electrode 7 the opposite substrate 5.

According version 5 implementation, bar spacer 22, which is provided on the opposite side of the substrate 5 and serves to maintain a constant thickness of the cell between multi substrate 1 and opposite substrate 5, ensured between two adjacent elements of the image, i.e. the middle area between sections 4c cut the corresponding two neighboring electrodes 4 picture elements (see Fig. 8). However, note that the version 5 implementation, we are not limited, given the fact that the column spacer 22 provided in section(s) 4c cut electrode(s) of the item(s) 4 images.

The number of bar spacers 22 is not limited to exactly the same, provided that you maintain a constant thickness of the cell between multi substrate 1 and opposite substrate 5. For example, a column spacer 22 can be provided in each area between two adjacent elements of the image, with a particular color(s).

According version 5 implementation, bar spacer 22 made of photosensitive resist having a high light transmittance in the visible region, and formed so as to have in advance a certain form. However, note that the version 5 implementation this is not limited.

According configuration, bar spacer 22 can be located in the flat part of the matrix of the substrate 1a, with the flat part is not provided with an electrode 4 image element. This helps improve the accuracy while maintaining the thickness of the cell.

In General, the disorder orientation of the liquid crystal molecules is likely to happen close to the area where ensured bar spacer 22. However, according version 5 implementation, because the column spacer 22 provided in sections 4c cut electrodes 4 image elements, you can suppress the influence of disorder focus on the effective display area, where the molecules of the liquid crystal are focused in predefined areas.

This allows the liquid crystal device display, which can effectively suppress the decline in the quality of the display, such as a blurred image.

[Option 6 implementation]

In the following description will be presented with the option of 6 implementation of the present invention with reference to Fig. 9. Option 6 implementation differs from the options 1-5 realization of the fact that each of the elements of the image is vertically elongated shape. Other configuration options 6 implementation is identical to the configuration options 1-5 implementation. For ease of explanation, the same reference positions are assigned to elements that have the same functions as components shown on the drawings variants 1-5 implementation, and descriptions of such constituent elements are omitted here.

Fig. 9 illustrates (i) schematic form of the electrode 4 item images, provided in the matrix 1c substrate liquid crystal display devices, in accordance with option 6 implementation, and (ii) the structure of sections 8 and 8a of the ledge, secured, as means of orientation of separation, on the counter-electrode 7 the opposite substrate 5.

In each of the options 1-5 implementation, it applies the configuration in which each element of the image is horizontally elongated shape (i.e. the longer side of each of the elements of the image is held in the transverse direction in the drawing). On the other hand, in the matrix 1c substrate, provided in liquid crystal display device option 6 implementation, each of the elements of the image is vertically elongated shape (i.e. the longer side of each of the elements of the image is held in the longitudinal direction in the drawing) (see Fig. 9).

Note that under option 6 implementation, shielding electrode 21 (described under option 2 exercise) formed with the use of counter-electrode 15 storage capacitor (see Fig. 9).

When each of the elements of the image is vertically elongated form, as described above, the shielding electrode 21 easy to generate using the appropriate one of the lines SLm-1, SLm, etc. data signal or counter-electrode 15 storage capacitor. In addition configuration options 6 implementation can give a result similar configuration, in which each element of the image is horizontally elongated shape.

[Option 7 implementation]

In the following description will be presented with the option of 7 implementation of the present invention with reference to Fig. 10. Option 7 implementation differs from the options 1-6 realization of the fact that (i) the number of sections (8b, 8c and 8d) hanging provided as a means of orientation of separation, on the counter-electrode 7 the opposite substrate 5 increased, and (ii) in the electrode 4 image element matrix substrate 1d provided with slots 4e and 4f as a means of orientation separation. Other configuration options 7 implementation is identical to the configuration options 1-6 implementation. For ease of explanation, the same reference positions are assigned to elements that have the same functions as components shown on the drawings options 1-6 implementation, and descriptions of such constituent elements are omitted here.

Fig. 10 illustrates (i) schematic form of the electrode 4 item image provided in the matrix substrate 1d liquid crystal display devices, in accordance with option 7 implementation, and (ii) the structure of partitions of the ledge, secured, as a means of orientation of separation, on the counter-electrode 7 the opposite substrate 5.

Section 8b, 8c and 8d of the ledge is provided as a means of orientation of separation, on the counter-electrode 7 the opposite substrate 5 (see Fig. 10). While the electrode 4 item image has slots 4e and 4f, going in either direction, are identical to those in which are sections 8b, 8c and 8d of the tab (see Fig. 10).

Even in the case when the number of means of orientation division increased in one (1) picture element, as described above, we can provide high-quality liquid crystal display device that can effectively suppress the decline in the quality of the display, such as blurred image, by providing serving section 4a of the electrode 4 elements of the image in order (i) to the same contact hole 17, when seen from the top of the LCD panel display, and (ii) is adjacent to drilldown section 4b, serving as a means of orientation division, neighboring electrode 4 image element.

When additionally provided with section 8d protrusion (the second shoulder), as a means of orientation of separation, on the counter-electrode 7 the opposite substrate 5, for placement in the peripheral area of the contact hole 17 (i.e. at the end contact openings 17) (see Fig. 10), you can more effectively suppress disorder the orientation of the liquid crystal molecules in the peripheral area of the contact hole 17.

[Option 8 implementation]

In the following description will be presented with the option of 8 implementation of the present invention with reference to Fig. 11.

Other configuration options 8 implementation is identical to the configuration options 1-7 implementation. For ease of explanation, the same reference positions are assigned a composite parts, having the same function as integral parts shown on the drawings variants 1-7 implementation, and descriptions of such constituent parts are omitted here.

Preferably black matrix 23 was at least partially provided in part the opposite substrate 5, and part coincides with acting section 4a of the electrode 4 elements of the image when viewed from the top of the LCD display panel.

This allows (i) effectively prevent disorder orientation of the liquid crystal molecules, light leakage and wastage of Ohr Hozer in the area where the generated pin hole 17, and (ii) to reduce the mixing of different colors of adjacent elements of the image. However, it should be noted that the option of 8 implementation is not limited.

In liquid crystal the display panel of the present invention, it is preferable that each of the electrodes image elements had an in-depth section, which is a partial cut electrode element of the image so that the advanced section is comprised of at least part of serving section adjacent electrode image element.

According configuration, advanced section of the electrode of the image element is made in such a form that she section of the image element immediately adjacent to drilldown section can be placed in the advanced section.

This configuration, can be used effectively in depth section of the electrode of the image element, which cannot be used as an effective display area. This helps to ensure the LCD display panel with high relative aperture and high transmittance.

In the LCD display panel of the present invention, it is preferable that at least part of the deep section of the electrode item image was essentially parallel to the ledge and/or deepening of common electrode, if seen from the top of the LCD display panel.

According configuration, advanced section of the electrode of the image element is made in such a form that she section of the image element immediately adjacent to drilldown section can be placed in the advanced section. In addition, at least part-depth section functions as a means of orientation separation.

Thanks to this configuration may (i) effectively use the advanced section of the electrode element of the image that cannot be used as an effective display area and (ii) to suppress the influence of disorder orientation caused through hole. This helps to ensure the LCD display panel with high relative aperture and high transmittance.

In the event that when shielding the electrode is not provided in the part where the wire to control the active element is partially open, (i) a disorder of the orientation of the liquid crystal is due to the influence of changes in electric potential in the wire and (ii) of the impurity ions trapped in a partially open part. In addition, part of which is captured impurity ions becomes the singularity, which calls for the defective orientation of the liquid crystal. This leads to defective LCD display panel display.
