Abstract
A liquid crystal display element comprising: 1) a pair of substrates including a first transparent substrate having thereon a transparent electrode and a polymeric alignment layer, and a second transparent substrate having thereon a transparent electrode and a polymeric alignment layer; 2) a ferroelectric liquid crystal material disposed between the pair of substrates; and 3) at least one of the first or second substrates further comprising a color filter array; and wherein the polymeric alignment layer is a crosslinked polyester which is derived from 1,4-phenylene bis(2-acrylic acid) and at least one aliphatic glycol that does not contain any aromatic dibasic acid component.
