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： In a liquid crystal display device using a cylindrical spacer to define the gap between a TFT substrate and a counter substrate, the TFT substrate does not include an organic passivation film, in which the cylindrical spacer is formed on an inorganic passivation film. An overcoat film is formed to cover a black matrix and color filters in the counter substrate. A concavo-convex mount is formed in the overcoat film. The top of the cylindrical spacer is brought into contact with the concavo-convex mount. The oriented film is not attached to the top of the cylindrical spacer and the convex portion of the concavo-convex mount. Thus, even if horizontal displacement occurs in the TFT substrate or the counter substrate, it is possible to prevent the occurrence of bright spots due to the scraping of the oriented film caused by the friction between the TFT substrate and the counter substrate.

摘要： An IPS liquid crystal display device intended to prevent generation of second image sticking after generation of initial DC image sticking.An alignment film has a two-layer structure comprising an upper alignment film and a lower alignment film. The upper alignment film is an optical alignment film formed of a polyamide acid ester as a precursor. The lower alignment film has a lower resistance value than the upper alignment film and also has a low photoconductive property. The lower alignment film is formed not using, as a precursor, a polyamide acid using PMDA as the starting material but using, as a precursor, the polyamide acid containing a sulfonic acid group or a carboxylic group, whereby the difference of the resistance between portions undergoing or not undergoing light irradiation in the pixel is decreased and generation of second image sticking can be prevented.
