Abstract:
A liquid crystal display device comprising:a pair of substrates in a spaced relationship with one another; a pair of alignment films, one said alignment film formed on each said substrate such that said alignment films face one another; and a liquid crystal layer, including plural liquid crystals, inserted between said pair of alignment films; said alignment films imparting a given pre-tilt angle to the liquid crystals, said alignment films being composed of a material containing at least two types of polymers having a prescribed initial alignment and different alignment variation rates in response to ultraviolet light irradiation; wherein said given pre-tilt angle is adjusted, without rubbing said alignment films, by exposing said alignment films to ultraviolet light; wherein said alignment films are comprised of a mixture of polymer x1 which exhibits a change of pre-tilt angle of at least 2Â° when irradiated with 0.5 (J/cm2) of ultra-violet rays and a polymer x2 which exhibits a change of pre-tilt angle of generally 0.5Â° when irradiated with at least 0.5 (J/cm2) of ultra-violet rays.
