Detailed description of embodiments

In the following description explains embodiments of the present invention with reference to the drawings. In the drawings referred to in the following description, identical or similar parts are assigned to identical or similar reference numbers. However, it should be noted that the drawings are illustrated schematically. Therefore, the relationship between the thickness and size when viewed from above and the ratio between the thicknesses of the respective layers, etc. differ from the actual. Additionally, the sizes and ratios, etc. can be shown differently on the drawings.

Option 1 implementation

Fig. 1 is a view in cross-section, schematically illustrating the configuration of a liquid crystal display device according to the variant 1 of the implementation of the present invention. As is illustrated in Fig. 1, the liquid crystal device 100 of the display under this option implementation includes W is cocrystallized panel 105 of the display panel 106 to enter the touch.

The liquid crystal panel 105 display composed of a TFT substrate 101, the substrate 102 of color filters and the glass substrate 103. The panel 106 to enter the tap consists of a glass substrate 103 and the protective film 104.

On the rear side surface (one side main surface) of the glass substrate 103 are provided with the TFT substrate 101 and the substrate 102 color filters. On the side of the front surface (the other side of the main surface) of the glass substrate 103 is provided with a protective film 104.

In other words, the liquid crystal panel 105 of the display consists of (i) glass substrate 103 and (ii) TFT substrate 101 and the substrate 102 of color filters provided on the back surface of the glass substrate 103. Additionally, the panel 106 to enter touch consists of (a) glass substrate 103 and (b) the protective film 104 provided on the side of the front surface of the glass substrate 103.

The liquid crystal device 100, the display is configured so that the liquid crystal panel 105 of the display panel 106 to enter touch are placed in this order. The panel 106 to input touch panel is to enter touch technology in the cell included in the liquid crystal panel 105 display.

The TFT substrate 101 is composed of a transparent insulating substrate, for approx the Roux, glass. On the TFT substrate and the pixel electrodes are matrix method.

The substrate 102 of color filters comprises an insulating substrate, for example, glass. On this substrate, the number of black matrices (BM) and color filters provided in the areas separated by the black matrix are arranged on the side of the glass substrate 103.

Additionally, the liquid crystal layer (not illustrated) is placed between the TFT substrate 101 and the color filter 102, and in this liquid crystal layer is placed a liquid crystal material.

According to the configuration required alignment between the existing pattern on the substrate 102 color filters, and that the existing figure is placed on the back surface of the glass substrate 103, and the structural pattern of the protective film 104, and this structural pattern is placed on the side of the front surface of the glass substrate 103. This is required in order to optimally set the relative position of the drawings. The following description explains the combination.

Fig. 2 is a view for describing the alignment between the rear side surface and the side of the front surface of the glass substrate 103. As is illustrated in Fig. 2, mark 11 combining (first symbol combination) is provided on podlog the E102 color filters. Mark 11 alignment has the shape of a cross when viewed from above (see A in Fig. 2). Mark 11 alignment has a size of 50×50 μm.

Of course, that the shape of the sign 11 alignment when viewed from above is not limited to the shape of a cross. For example, the mark 11 of the combination may be in the form of a rectangle (50 × 50 µm) or circular (diameter 50 μm) when viewed from above. In other words, the shape and size of the sign 11 alignment when viewed from above may be properly selected according to the detected mark 11 alignment.

Mark 11 alignment can be manufactured, for example, of a metal film for black matrices placed on the substrate 102 color filters. This makes optional placement on top of a separate metal film for forming the mark 11 combination. Accordingly, it is possible to further reduce the number of stages and the material cost of the liquid crystal device 100 of the display.

Structural pattern on the glass substrate 103 is combined with the sign 11 aligners, which serves as the reference point.

On the glass substrate 103 is formed structural drawing, optimally positioned relative to the mark 11 combination. Structural drawing include mark 12 combining (second character combination). Mark 12 alignment also has the shape of a cross when viewed from above (see B is a of Fig. 2).

Of course, that the shape of the sign 12 alignment when viewed from above is not limited to the shape of a cross, as in the case of the above mark 11 combination. For example, mark 12 combination can be in the form of a rectangle (50×50 µm) or circular (diameter 50 μm) when viewed from above. In other words, the shape and size of the sign 12 alignment when viewed from above may be properly selected according to the detected mark 12 alignment.

According to the liquid crystal device 100 of the display sign 12 alignment consists of a known transparent conductive film (transparent member), for example, ITO, IZO, or ZnO. The sign 12 is provided by combining opaque film (opaque element) 13 (described below).

Opaque film 13 may be of any shape when viewed from above, provided that the opaque film 13 has a shape which at least covers the sign 12 alignment when viewed from above.

The following description explains the stages of formation of the mark 11 of the alignment mark 12 alignment and opaque film 13. Fig. 3 is a view for describing the stages of formation of the mark 11 of the alignment mark 12 alignment and opaque film 13.

First, as illustrated in (a) in Fig. 3, a transparent conductive film 12a is placed on top of the glass substrate 103. P is otracina conductive film 12a is placed on top of the entire surface of the glass substrate 103.

Transparent conductive film 12a can be manufactured, for example, of the electrode transparent conductive film for touch input, which is the panel 106 to the input touch. Electrode transparent conductive film for touch input is a film formed on the glass substrate 103. This makes optional placement on top of a separate transparent conductive film for the formation of the mark 12 of the combine. Accordingly, it is possible to further reduce the number of stages and the material cost of the liquid crystal device 100 of the display.

Next, as illustrated at (b) in Fig. 3, figure 14 is formed of photoresist on the transparent conductive film 12a. Figure 14, the photoresist is patterned formation of the mark 12 of the combine. Structural drawing of figure 14, the photoresist is combined with the sign 11 aligners, which serves as the reference point.

Here it should be noted that according to conventional LCD device 500 display figure 53 photoresist is formed on the metal film 52b (see (b) in Fig. 13). Figure 53 photoresist is pattern to remove the metal film 52b, which are placed above the area of the overlapping substrate 502 color filters.

This is because, provided that the metal film 52b is placed on top in the her surface of the glass substrate 503, it is impossible to detect the mark 51 alignment on the substrate 502 color filters.

In other words, as described above, the conventional liquid crystal device 500 of the display requires a step of removing the metal film 52b, which are placed above the area of the overlapping substrate 502 colored filters to combine structural pattern on the glass substrate 503 with the sign 51 alignment, which serves as the reference point.

It is very problematic to reduce the number of steps and material cost of the LCD device 500 display.

On the contrary, according to the liquid crystal device 100 of the display, since the sign 12 alignment consists of a transparent conductive film 12a, it is possible to detect the mark 11 alignment through the transparent conductive film 12a placed on top of the entire surface of the glass substrate 103, and thus it is possible to combine structural pattern on the glass substrate 103 with the sign 11 aligners, which serves as the reference point (see (b) in Fig. 3).

This makes the optional step of removing the metal film 52b for the detection of the mark 51 of the alignment (see (b) in Fig. 13) and thereby reduces the number of stages and the material cost of the liquid crystal device 100 of the display.

Next, as illustrated at (c) in the IG. 3, a transparent conductive film 12a is removed according to figure 14 of the photoresist. In other words, the sign 12 alignment is formed on the glass substrate 103.

Next, as illustrated at (d) in Fig. 3, a metal film 13a is placed on top of the glass substrate 103 and the mark 12 of the combine. Metal film 13a is placed from above on the entire surface of the glass substrate 103. After the metal film 13a is placed on top, figure 15 of photoresist is formed on the metal film 13a.

Metal film 13a is a film to set the opaque mark 12 combination, consisting of a transparent conductive film 12a. As in the case with the sign 11 alignment, structural drawing on mark 12 combination is combined with the sign 12 alignment, which serves as a landmark. Therefore, the sign 12 alignment should be set to opaque so that it is discoverable.

Metal film 13a can be manufactured, for example, of a metal film of the metal wires that make up the panel 106 to enter the touch, and these metal wires are provided on the glass substrate 103. This makes optional placement on top of a separate metal film, to set the mark 12 combining opaque, and thus can further reduce the number of E. the UPS and material costs on the liquid crystal device 100 of the display.

Next, as illustrated at (d) in Fig. 3, figure 15 of photoresist is formed on the metal film 13a. Figure 15, the photoresist is patterned forming an opaque film 13, which is the sign 12 combining opaque. Structural drawing of figure 15, the photoresist is combined, for example, with the sign 12 alignment, which serves as a landmark. Of course, that the structural pattern of figure 15, the photoresist can be combined with the sign 11 aligners, which serves as the reference point.

As described above, the opaque film 13 may be of any shape when viewed from above, provided that the opaque film 13 has a shape which at least covers the sign 12 alignment when viewed from above. This is due to the fact that the shape of the sign 12 alignment when viewed from above becomes opaque and thus becomes detectable, if opaque film 13 when viewed from above has a shape which at least covers the sign 12 alignment when viewed from above.

Next, as illustrated at (e) in Fig. 3, a metal film 13a is removed according to figure 15 of the photoresist. In other words, the opaque film 13 is formed on the glass substrate 103. After the metal film 13a is removed, figure 15 of the photoresist.

In the head of renie, as illustrated in (f) in Fig. 3, the protective film 104 is placed on top of the glass substrate 103 and an opaque film 13.

As described, according to the liquid crystal device 100 display for option 1 : implementation of the present invention, since the sign 12 alignment consists of a transparent conductive film 12a, it is possible to detect the mark 11 alignment through the transparent conductive film 12a placed on top of the entire surface of the glass substrate 103, and thus it is possible to combine structural pattern on the glass substrate 103 with the sign 11 aligners, which serves as the reference point.

Accordingly, it is not necessarily to perform the step of removing the transparent conductive film 12a for detection mark 11 alignment, and thus can reduce the number of stages and the material cost of the liquid crystal device 100 of the display.

Option 2 implementation

The following description explains option 2 implementation of the present invention. As in the case of option 1 implementation under this option require alignment between the existing pattern on the substrate 102 color filters, and that the existing figure is placed on the back surface of the glass substrate (transparent substrate) 103, and a structural drawing under the protective film 104 and this structural pattern is placed on the side of the front surface of the glass substrate 103. This is required in order to optimally set the relative position of the figures.

Present an implementation option differs from option 1 implementation stages of the formation of character combination for use in combination. Fig. 4 is a view for describing the alignment between the rear side surface and the side of the front surface of the glass substrate 103.

As is illustrated in Fig. 4, mark 11 alignment is provided on the substrate 102 color filters. Mark 11 alignment has the shape of a cross when viewed from above (see C in Fig. 4). As mark 11 alignment is identical to the sign of the alignment option 1 implementation, its description is omitted here.

On the glass substrate 103 is formed structural drawing, optimally positioned relative to the mark 11 combination. Structural drawing include mark 16 combining (second character combination). Mark 16 alignment also has the shape of a cross when viewed from above (see D in Fig. 4).

It should be noted that the mark 16 combining different from mark 12 alignment option 1 implementation the fact that he is a protrusion (protruding part)formed on the glass substrate 103, and this ledge is part of the glass substrate 103.

The protrusion may be formed, for example, a glass substrate 103, when the article is glass substrate 103 is formed in a thin film. This makes optional separate step of forming the glass substrate 103 in a thin film to form the mark 16 alignment, and thereby further reduces the number of steps and material costs on the liquid crystal device 100 of the display.

As in the case of the above mark 11 combinations in the form of mark 16 alignment when viewed from above is not limited to the shape of a cross. For example, mark 16 alignment may be in the form of a rectangle (50 × 50 µm) or circular (diameter 50 μm) when viewed from above. In other words, the shape and size of the sign 16 alignment when viewed from above may be properly selected according to the detected mark 16 alignment.

As in the case of option 1 implementation, opaque film 13 is provided on the sign 16 alignment. Because opaque film 13 is identical to the opaque film for the version 1 implementation, its description is omitted here.

The following description explains the stages of formation of the mark 11 of the alignment mark 16 combinations and opaque film 13. Fig. 5 is a view for describing the stages of formation of the mark 11 of the alignment mark 16 combinations and opaque film 13.

Structural drawing of figure 17, the photoresist is combined with the sign 11 aligners, which serves as the reference point.

Next, as illustrated at (b) in Fig. 5, the glass substrate 103 is removed according to figure 17 of the photoresist. In other words, mark 16 alignment, which consists of a protrusion, which is part of the glass substrate 103, is formed on the glass substrate 103.

Next, as illustrated at (c) in Fig. 5, the metal film 13a is placed on top of the glass substrate 103 and the mark 16 alignment. After the metal film 13a is placed on top, figure 18 of photoresist is formed on the metal film 13a. Since the metal film 13a is identical to the metal film for the version 1 implementation, its description is omitted here.

Next, figure 18 of photoresist is formed on the metal film 13a. Figure 18 photoresist is patterned forming an opaque film 13, which sets the mark 16 combining opaque. Structural drawing of figure 18, the photoresist is combined, for example, signed 16 alignment, which serves as a landmark. Of course, that the structural pattern of figure 18, the photoresist can be combined with the sign 11 aligners, which serves as the reference point.

Next, as illustrated at (d) in Fig. 5, the metal film 3a is removed according to figure 18 of the photoresist. In other words, the opaque film 13 is formed on the glass substrate 103. After the metal film 13a is removed, figure 18 of photoresist.

Finally, as illustrated at (e) in Fig. 5, the protective film 104 is placed on top of the glass substrate 103 and an opaque film 13.

As described, according to the liquid crystal device 100 display for option 2 implementation of the present invention, since the sign 16 alignment consists of a protrusion, which is part of the glass substrate 103, it is possible to detect the mark 11 alignment through the glass substrate 103, and thus it is possible to combine structural pattern on the glass substrate 103 with the sign 11 aligners, which serves as the reference point.

Accordingly, it is possible to reduce the number of stages and the material cost of the liquid crystal device 100 of the display.

Option 3 implementation

The following description explains option 3 implementation of the present invention. Fig. 6 is a view in cross-section, schematically illustrating the configuration of a liquid crystal display device according to the variant 3 implementation of the present invention. As is illustrated in Fig. 6, the liquid crystal device 200 of the display according to the present variant implementation includes a panel 205 for the ode touch and LCD panel 206 of the display.

Panel 205 to enter the tap consists of a protective film 201 and the glass substrate 202. The liquid crystal panel 206 of the display consists of a glass substrate 202, the substrate 203 color filter and TFT substrates 204.

On the rear side surface (one side main surface) of the glass substrate 202 is provided with a protective film 201. On the side of the front surface (the other side of the main surface) of the glass substrate 202 is provided, the substrate 203 color filter and TFT-substrate 204.

In other words, the panel 205 to input touch consists of (i) glass substrate 202 and (ii) the protective film 201 provided on the back surface of the glass substrate 202. Additionally, the liquid crystal panel 206 of the display consists of (a) glass substrate 202 and (b) substrate 203 color filter and TFT substrates 204, which are provided on the front surface of the glass substrate 202.

The liquid crystal device 200, the display is configured so that the panel 205 to enter touch and LCD panel display 206 are placed in this order. Panel 205 to input touch panel is to enter touch technology in the cell included in the liquid crystal panel 206 of the display.

The substrate 203 color filters consists of isolating podlog and, for example, glass. On this substrate, the number of black matrices (BM) and color filters provided in the areas separated by the black matrix, is placed on the side of the glass substrate 202.

TFT-substrate 204 is composed of a transparent insulating substrate, for example, glass. On the TFT substrate and the pixel electrodes are matrix method.

Additionally, the liquid crystal layer (not illustrated) is placed between the substrate 203 color filter and TFT substrate 204, and in this liquid crystal layer is placed a liquid crystal material.

According to the configuration required alignment between the existing pattern on the protective film 201, and that the existing figure is placed on the back surface of the glass substrate 202, and the structural pattern of the substrate 203 color filters, and this structural pattern is placed on the side of the front surface of the glass substrate 202. This is required in order to optimally set the relative position of the drawings. The following description explains the combination.

Fig. 7 is a view for describing the alignment between the rear side surface and the side of the front surface of the glass substrate 202. As is illustrated in Fig. 7, the mark 21 combining (first symbol combination) obespecivaet the protective film 201. Mark 21 alignment has the shape of a cross when viewed from above (see E in Fig. 7). Mark 21 alignment has a size of 50x50 mm.

Of course, that the form of the mark 21 alignment when viewed from above is not limited to the shape of a cross. For example, the mark 21 of the combination may be in the form of a rectangle (the size of 50×50 μm) or circular (diameter 50 μm) when viewed from above. In other words, the shape and size of the mark 21 alignment when viewed from above may be properly selected according to the detected sign 21 alignment.

Mark 21 alignment can be manufactured, for example, of a metal film of the metal wires that make up the panel 205 to enter touch, and this metal film is provided on the protective film 201. This makes optional placement on top of a separate metal film for forming the mark 21 alignment. Accordingly, it is possible to further reduce the number of stages and the material cost of the liquid crystal device 200 of the display.

Structural pattern on the glass substrate 202 is combined with the sign 21 alignment, which serves as the reference point.

On the glass substrate 202 is formed structural drawing, optimally positioned relative to the mark 21 alignment. Structural drawing include mark 22 combining (second sign of the owls is edenia). The sign 22 alignment also has the shape of a cross when viewed from above (see F in Fig. 7).

Of course, that the shape of the sign 22 overlapping when viewed from above is not limited to the shape of a cross, as in the case of the above 21 sign of convergence. For example, the mark 22 of the combination may be in the form of a rectangle (the size of 50×50 μm) or circular (diameter 50 μm) when viewed from above. In other words, the shape and the size of the plate 22 overlapping when viewed from above may be properly selected according to the detected sign 22 alignment.

According to the liquid crystal device 200 of the display sign 22 alignment consists of known transparent polymer film (transparent member), for example alkaline resin or epoxy resin. On the mark 22 is provided by combining opaque film (opaque element) 23 (described below).

Opaque film 23 may be of any shape when viewed from above, provided that the opaque film 23 has a shape which at least covers the mark 22 overlapping when viewed from above.

The following description explains the stages of formation of the mark 21 of the alignment mark 22 of the combination and an opaque film 23. Fig. 8 is a view for describing the stages of formation of the mark 21 of the alignment mark 22 of the combination and an opaque film 23.

First, as p is illyustrirovano at (a) in Fig. 8, a transparent polymer film 22a is applied to the glass substrate 202. Transparent polymer film 22a is applied to the entire surface of the glass substrate 202.

Transparent polymer film 22a can be manufactured, for example, of the photosensitive transparent resin film, which forms the basis of the substrate 203 color filters, and this transparent polymer film is provided on the glass substrate 202. This makes optional use of separate transparent polymer film for the formation of the mark 22 combination. Accordingly, it is possible to further reduce the number of steps and material costs for the liquid crystal device 200 of the display.

Next, as illustrated at (b) in Fig. 8, figure 24 of photoresist is formed on the transparent polymer film 22a. Figure 24 of photoresist is patterned formation of the mark 22 combination. Structural drawing of figure 24, the photoresist is combined with the sign 21 alignment, which serves as the reference point.

According to the liquid crystal device 200 of the display, since the sign 22 alignment consists of a transparent polymer film 22a, it is possible to detect the mark 21 alignment through the transparent polymer film 22a, applied to the entire surface of the glass substrate 202, and thus it is possible to combine structural drawings is to on the glass substrate 202 with the sign 21 align, which serves as the reference point.

Next, as illustrated at (c) in Fig. 8, a transparent polymer film 22a is removed according to figure 24 of photoresist. In other words, the sign 22 alignment is formed on the glass substrate 202.

Next, as illustrated at (d) in Fig. 8, a metal film 23a is placed on top of the glass substrate 202 and the sign 22 combination. Metal film 23a is placed from above on the entire surface of the glass substrate 202. After the metal film 23a is placed on top, figure 25, the photoresist is formed on the metal film 23a.

Metal film 23a is a film to set the opaque mark 22 combination, consisting of a transparent polymer film 22a. As in the case with the sign 21 alignment, structural drawing on familiar 22 combination is combined with the sign 22 alignment, which serves as a landmark. Therefore, the sign 22 alignment should be set to opaque so that it is discoverable.

Metal film 23a is made, for example, of a metal film for black matrices, which must be provided on the substrate 203 color filters, and this metal film is provided on the glass substrate 202. This makes optional placement on top of a separate metal film to form not prozrachnuy film 23, and thus it is possible to further reduce the number of stages and the material cost of the liquid crystal device 200 of the display.

Next, figure 25, the photoresist is formed on the metal film 23a. Figure 25, the photoresist is patterned forming an opaque film 23, which is the sign 22 combining opaque. Structural drawing of figure 25, the photoresist is combined, for example, signed 22 alignment, which serves as a landmark. Of course, that the structural pattern of figure 25, the photoresist can be combined with the sign 21 alignment, which serves as the reference point.

As described above, the opaque film 23 may be of any shape when viewed from above, provided that the opaque film 23 has a shape which at least covers the mark 22 overlapping when viewed from above. This is due to the fact that the shape of the mark 22 overlapping when viewed from above becomes opaque and thus becomes detectable, if opaque film 23 when viewed from above has a shape that completely covers the mark 22 overlapping when viewed from above.

Next, as illustrated at (e) in Fig. 8, a metal film 23a is removed according to figure 25 of the photoresist. In other words, the opaque film 23 is formed on the glass substrate 202. After TRG is how metal film 23a is removed, removed figure 25 photoresist.

Finally, as illustrated at (f) in Fig. 8, the substrate 203 color filters is formed on the glass substrate 202 and an opaque film 23.

As described, according to the liquid crystal device 200 of the display for option 3 implementation of the present invention, since the sign 22 alignment consists of a transparent polymer film 22a, it is possible to detect the mark 21 alignment through the transparent polymer film 22a, applied to the entire surface of the glass substrate 202, and thus it is possible to combine structural pattern on the glass substrate 202 with the sign 21 alignment, which serves as the reference point.

This makes the optional step of removing the transparent polymer film 22a for the detection of the mark 21 alignment, and thereby reduces the number of stages and the material cost of the liquid crystal device 200 of the display.

It should be noted that, although the mark 22 alignment becomes opaque due to the cover of the mark 22 combining metal film 23a in this embodiment, this does not imply a limitation on the present invention.

For example, the sign 22 alignment can be specified opaque due to the blackening (exposure processing darkening) of the mark 22 of the combination formed from transparent polim the nuclear biological chemical (NBC film 22a, by irradiating the mark 22 in alignment with a laser.

Option 4 implementation

As in the case of option 3 implementation under this option require alignment between the existing pattern on the protective film 201, and that the existing figure is placed on the back surface of the glass substrate 202, and the structural pattern of the substrate 203 color filters, and this structural pattern is placed on the side of the front surface of the glass substrate 202. This is required in order to optimally set the relative position of the figures.

Present an implementation option differs from option 3 implementation stages of the formation of character combination for use in combination. Fig. 9 is a view for describing the alignment between the rear side surface and the side of the front surface of the glass substrate 202.

On the glass substrate 202 is formed structurn the second picture, optimally positioned relative to the mark 21 alignment. Structural figure includes 26 sign combination (the second character combination). Sign 26 alignment also has the shape of a cross when viewed from above (see H in Fig. 9).

It should be noted that the mark 26 combining different from the sign 22 alignment option 3 implementation the fact that he is a protrusion formed on the glass substrate 202, and this ledge is part of the glass substrate 202.

The protrusion may be formed, for example, a glass substrate 202, when the glass substrate 202 is formed in a thin film. This makes optional separate step of forming the glass substrate 202 in a thin film to form the mark 26 alignment, and thereby further reduces the number of steps and material costs on the liquid crystal device 200 of the display.

As in the case of the above 21 sign combinations in the form of the mark 26 overlapping when viewed from above is not limited to the shape of a cross. For example, the mark 26 of the combination may be in the form of a rectangle (the size of 50×50 μm) or circular (diameter 50 μm) when viewed from above. In other words, the shape and the size of the plate 26 overlapping when viewed from above may be properly selected according to the detected sign 26 from the placement.

As in the case of option 3 implementation, opaque film 23 is provided on the label 26 alignment. Because opaque film 23 is identical to the opaque film version 3 implementation, its description is omitted here.

Next, as illustrated at (b) in Fig. 10, the glass substrate 202 is removed according to figure 27, the photoresist. In other words, the mark 26 alignment, which consists of a protrusion, which is part of the glass substrate 202, is formed on the glass substrate 202.

Next, as illustrated at (c) in Fig. 10, a metal film 23a is placed on top of the glass substrate 202 and the sign 26 alignment. After the metal film 23a is placed on top (figure 28) of photoresist is formed on the metal film 23a. As the metal film 23a is identical metal film version 3 implementation its description is omitted here.

Next, figure 28 of photoresist is formed on the metal film 23a. Figure 28 photoresist is patterned forming an opaque film 23, which sets the mark 26 combining opaque. Structural drawing of figure 28, the photoresist is combined, for example, signed 26 alignment, which serves as a landmark. Of course, that the structural pattern of figure 28, the photoresist can be combined with the sign 21 alignment, which serves as the reference point.

Next, as illustrated at (d) in Fig. 10, a metal film 23a is removed according to figure 28 photoresist. In other words, the opaque film 23 is formed on the glass substrate 202. After the metal film 23a is removed, figure 28 photoresist.

Finally, as illustrated at (e) in Fig. 10, the substrate 203 color filters is formed on the glass substrate 202 and an opaque film 23.

This reduces the number of steps and material costs on the liquid crystal device 200 of the display.

It should be noted that, although the mark 26 alignment becomes opaque due to the cover of the mark 26 combining metal film 23a in this embodiment, this does not imply a limitation on the present invention.

For example, the mark 26 alignment can be specified opaque due to the blackening (exposure processing darkening) of the mark 26 of the combination consisting of a protrusion of the glass substrate 202, by irradiating the mark 26 in alignment with a laser.
