ABSTRACT:
An alignment-film in which the pretilt angle is changed by ultraviolet irradiation, a material for forming the same, a liquid crystal display device using the alignment film, a method for producing an alignment-film formation material, and a method for producing an alignment film. Ultraviolet irradiation causes large changes in pretilt angle but few changes in electrical characteristics, and a liquid crystal display device free from deterioration of the liquid crystal, image sticking, or the occurrence of flicker results. A first polymer forms the underlying principal layer and a second polymer forms thereon a surface layer thinner than the principal layer. The first polymer may exhibit a small change in electrical characteristics due to ultraviolet radiation and the second polymer may exhibit a large change in pretilt angle due to ultraviolet radiation.
