摘要： It is an object of the present invention to suppress light leakage in a dark state which is generated by rubbing treatment. A liquid crystal material containing an ultraviolet curable liquid crystalline monomer at a concentration of more than 0 wt % and not more than 1.0 wt % is used for a liquid crystal layer, and the liquid crystal layer is irradiated with ultraviolet rays. By applying such a liquid crystal layer to a liquid crystal display device, light leakage in a dark state can be suppressed, and the black display can be improved. Therefore, a liquid crystal display device with an excellent contrast and high display quality can be obtained.

摘要： External light is reflected due to a difference in refractive indices of a black matrix and a glass substrate. When the black matrix is a black resin, there is a difference in refractive indices of the black resin and a first substrate. Also, there is a difference in refractive indices of the colored layer and the first substrate. Therefore, external light is slightly reflected. There is a problem in that the reflected light reduces contrast. A structure in which one polarizing element having dichroism is interposed between a pair of substrates is employed, and a light interference layer is provided between a color filter and a glass substrate, whereby a difference in refractive indices is moderated to reduce light reflection.

摘要： A liquid crystal dripping method has a problem in that an uncured sealant increases in width at the time of attaching a pair of substrates and thus a liquid crystal material enters the sealant and unevenness occurs in the inner periphery of the sealant. A region in which reduced is the speed of diffusion of liquid crystal at the time of attaching a pair of substrates is provided between a sealant and an orientation film. Further, time for diffusing the liquid crystal and coming in contact with the sealant is made long. Accordingly, the sealant is subjected to photo-curing before the liquid crystal comes in contact with the sealant. The region in which reduced is the speed of diffusion of the liquid crystal is formed using a material for forming a vertical orientation film, a silane coupling agent, a substance having a photocatalytic function, or the like.

摘要： An object is to provide a highly reliable liquid crystal display device which includes a liquid crystal layer exhibiting a more stable blue phase. Another object is to provide a method for manufacturing a liquid crystal display device with high yield. Polymer stabilization treatment is performed as follows: a photocurable resin is added to a liquid crystal material exhibiting a blue phase, and the photocurable resin is selectively polymerized by scanning a liquid crystal layer provided between a first substrate and a second substrate with light in a certain direction. Thus, a first region where the light irradiation treatment is performed and a second region where the light irradiation treatment is not performed are formed in the liquid crystal layer. Since polymerization of the photocurable resin proceeds in the first region, the polymerization degree of the photocurable resin in the first region is higher than that in the second region.
