Abstract: A liquid crystal display device includes a TFT substrate having a first alignment film and an opposing substrate having a second alignment film with liquid crystals sandwiched therebetween. One of the first and second alignment films, comprises a first polyimide produced via polyamide acid ester containing cyclobutane as a precursor and a second polyimide produced via polyamide acid as a precursor. The polyamide acid has a higher polarity than that of the polyamide acid ester. The one of the first and second alignment films is responsive to photo-alignment. A first side of the one of the first and second alignment films is adjacent to the liquid crystals, and a second side thereof is closer to one of the TFT substrate and the counter substrate than the first side. The first side contains more of the first polyimide and less of the second polyimide than the second side.

Abstract: To form an optical alignment film having large anchoring strength and suppress an AC afterimage of a liquid crystal display device, in a liquid crystal display device of an IPS mode. In an alignment film material subjected to optical alignment processing, polyimide which becomes a rigid high molecule and polyimide which becomes a flexible high molecule are mixed and used. The material of the present invention can easily rotate oligomer after irradiating polarized ultraviolet rays and improve a UV-absorbed two-color ratio of an alignment film. Accordingly, an anchoring strength for liquid crystals by the alignment film is large to suppress an AC afterimage.
