Abstract:
1. A liquid crystal display device comprising: a pair of substrates in a predetermined spaced relationship with each other; a pair of alignment films, one said alignment film formed on each said substrate such that said alignment films face each other; and a liquid crystal layer inserted between said pair of alignment films, said alignment films being comprised of a material providing vertical orientation to liquid crystal molecules of said liquid crystal layer and containing a mixture of at least two types of polymers having different variation rates of a pre-tilt angle in response to ultraviolet light irradiation, wherein one type of said two types of polymers changes an orientation of the liquid crystal molecules from the initial state upon being irradiated with ultraviolet rays, and the other type of said two types of polymers generally maintains the initial state of orientation of the liquid crystal molecules.
