ABSTRACT:
To provide a liquid crystal display device provided with a liquid crystal alignment layer which is excellent in adhesion to a glass substrate and which has less dependency of display characteristics upon a viewing angle.
A liquid crystal display device having a liquid crystal layer between a pair of substrates each comprising a transparent electrode having provided thereon an alignment layer wherein the alignment layers are arranged inside so as to face each other, characterized in that a mixture of a polyamide (A) containing siloxane component as a constituting unit and a polymer (B) having a property of aligning the liquid crystal in such a manner that the direction of a long axis of the liquid crystal molecule projected on the surface of the substrate is different from a rubbing direction is used as an alignment layer material of at least one of the facing surfaces on the pair of substrates.
