ABSTRACT:
A liquid crystal cell is fabricated by successively coating on a substrate a first alignment layer, which includes material substantially impervious to ultraviolet irradiation and a second alignment layer which includes a photosensitive material which is insoluble if not exposed to ultraviolet light, but readily dissolved in a developing solution after exposure. Portions of the first and second alignment layers corresponding to an inner space of a cell are alternately exposed so that different alignment controlling forces are respectively obtained for both alignment layers after rubbing.
