ABSTRACT:
37 A liquid crystal display device is provided which comprises a cell unit having a pair of optically transparent substrates each having an optically transparent electrode layer and an alignent layer for liquid crystal formed in this order on one side of the substrate. The paired substrates is in spaced relation with each other and is arranged such that the respective alignment layers are facing each other. A liquid crystal is contained in the space between the paired substrates. The alignment layers are made of a polymer material having both a ring structure and a substituted group at side chains thereof and are subjected to rubbing treatment. The use of the alignment layers ensures a great pretilt angle for liquid crystal molecules.
