Liquid crystal display device |
abstract |
A liquid crystal display device in which a good voltage holding ratio is retained for a long period of time and occurrence of image sticking and stain in a display screen is prevented by using a photo-alignment film. The liquid crystal display device includes an active matrix liquid crystal panel and a backlight. The liquid crystal panel includes a liquid crystal layer, a pair of substrates that sandwich the liquid crystal layer in between, and an alignment film disposed on a liquid crystal layer side surface of each of the substrates. The alignment films are photo-alignment films formed from a material that exhibits a photo-alignment characteristic, and contain carboxyl groups on the liquid crystal layer side. The liquid crystal layer contains a liquid crystal material and at least one kind of quinone derivative selected from the group consisting of benzoquinone derivatives and anthraquinone derivatives. |
