Method of producing oriented liquid crystal layer Before depositing a liquid crystal layer, the porous structure of a layer of a metal oxide substrate is modified by depositing onto its surface a liquid isotropic solution of a dichroic substance, followed by evaporation of the solvent from said liquid solution to form on the surface and inside the porous layer of metal oxide a layer of a solid-state dichroic substance, thermally treating said porous layer, treating the obtained layer with a solvent without the dichroic substance to obtain a monomolecular layer of dichroic substance on the surface and inside the pores of the metal oxide. The layer of dichroic substance is then heated to evaporate residual solvent from the porous structure and the obtained monomolecular layer of dichroic substance is irradiated with activating optical radiation which is absorbed by the dichroic substance to provide the given orientation of anisotropic molecules in the monomolecular layer of dichroic substance. The substrate with the irradiated monomolecular layer of dichroic substance is further heated and liquid crystal material is then deposited on the obtained surface of the monomolecular layer of dichroic substance to form an oriented liquid crystal layer. |

The first portion is a portion on which the edge of the first electrode overlaps with a recess (22a, 22b), or a portion on which the edge of the first electrode overlaps with the prolonged line of the recess (22a, 22b), closest to the edge. The second portion is a portion on which the edge of the first electrode overlaps with a second domain stabilisation structure (44a, 44b), or a portion on which the first electrode overlaps with the prolonged line of the domain stabilisation structure (44a, 44b), closest to the edge. |

Method of injecting droplet of levelling material and apparatus for realising said method Disclosed is a method and an apparatus for droplet injection, capable of preventing development of a linear defect which is the result of operation of a defective nozzle from multiple nozzles of a jet head which injects a disproportionate droplet volume, which manifests itself as a visual defect when the image is displayed on a liquid crystal panel. When adjacent streams of the droplets of levelling material, which are formed as a result of movements in the direction Y of the jet head, are merged to form a levelling film on a substrate, the value of displacement in the direction X of the jet head is set such that adjacent streams are formed by different nozzles. |

At least two stable or metastable ordering of liquid crystal are realized. Switching aid which causes the switching of liquid crystal material between switches has aid intended for optical illumination of the device. Device can provide the supply of linear polarized light for inducing torsion in liquid crystal. Alternatively ordering of liquid crystal can be switched by means of aid for supplying second energy, for example, electric field. In this case light serves to generate heat which helps to switching. One or both energy sources can be used locally for switching chosen areas or pixels. Energy levels on bistable substrate can be controlled by using oligomer adding (slippery surface). |
