ABSTRACT:
A liquid crystal display device including a pair of substrates in a spaced relationship with one another. A pair of alignment films are provided, one alignment film being formed on each substrate such that the alignment films face one another. A liquid crystal layer; including plural liquid crystals, is inserted between the pair of alignment films, wherein the alignment films impart a given pre-tilt angle to the liquid crystals. The alignment films are 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 ray irradiation. The pre-tilt angle being adjusted, without rubbing the alignment films, through ultraviolet exposure of the alignment films.
