ABSTRACT:
A method for domain-dividing a liquid crystal alignment film, which comprises (1) applying a radiation-sensitive resin composition onto a liquid crystal alignment film aligned in one direction and formed on a substrate, (2) exposing the radiation-sensitive resin composition through a predetermined pattern, (3) carrying out a development with an aqueous solution containing 0.01 to 1.5% by weight of an alkaline compound to partially protect the liquid crystal alignment film, (4) aligning an exposed portion of the liquid crystal alignment film in another direction and (5) removing the radiation-sensitive resin composition; and a liquid crystal device having a liquid crystal display device with the domain-divided liquid crystal alignment film.
