摘要： In a liquid crystal display device, a light shielding film, a color filter, an overcoat film, and an alignment film are formed in this order on a counter substrate. However, the alignment film is not formed in a seal portion. When the alignment film is subjected to photo-alignment with ultraviolet radiation, a portion of the overcoat film not covered with the alignment film is degraded by ultraviolet radiation. In order to prevent moisture penetrating from the degraded overcoat film from reaching the light shielding film to thereby alter the light shielding film and from causing the peeling of the light shielding film, the color filter is disposed below the overcoat film to block the moisture.

摘要： Each pixel formed on a TFT substrate includes a pixel electrode, and a TFT, a color filter, an opposed electrode and an insulating film are interposed between the pixel electrode and the TFT substrate. A liquid crystal layer is interposed between the TFT substrate and an opposed substrate. An alignment film is provided on each surface of the TFT substrate and the opposed substrate, the each surface being in contact with the liquid crystal layer. A material with high photoconductivity is used for forming the alignment film so as to suppress DC afterimage. Meanwhile, each thickness of the color filter for the respective colors is changed for preventing a yellow shift resulting from absorption of high intensity of light with short wavelength by the alignment film.

摘要： An image retention phenomenon and black unevenness generated after long-time operation in the liquid crystal device are prevented. By using a material having a polyamide acid ester as a precursor less likely to adsorb impurities on a boundary for an alignment film and a material having a dielectric constant anisotropy Δε of 5 or less for liquid crystals, adsorption of an antioxidant dispersed in the liquid crystals is suppressed to prevent oxidation of the liquid crystals. The extent that impurities are intruded into the liquid crystals is reduced by restricting the dielectric constant anisotropy Δε of the liquid crystals to 5 or less, thereby capable of preventing the image retention phenomenon and the black unevenness.
