ABSTRACT:
A liquid crystal device has a substrate with first and second alignment layers thereon. The first alignment layer is unidirectionally aligned. The second alignment layer is a layer formed of a cured twisted reactive mesogen composition which is patterned by masking, curing and dissolving uncured regions of the layer so as to expose first alignment regions defined by the layer, and to leave second alignment regions in the layer. The first alignment regions have a different alignment direction from that of the second alignment regions. A liquid crystal layer is provided over the resultant alignment layer structure.
