ABSTRACT:
A liquid crystal display device having a liquid crystal material put between a pair of substrates each comprising a transparent electrode and an alignment layer formed thereon in such a manner that the alignment layers are arranged inside so as to face each other, characterized in that at least one of said pair of substrates has an alignment layer formed thereon, which is capable of forming two or more different alignment states of the liquid crystal by an aligning processing in one direction, and at least one of said pair of substrates has an alignment layer formed thereon which generates a pretilt angle of the liquid crystal of at least 2.degree.. The device has a high contrast and less dependency of display characteristics on the viewing angle.
