Abstract
An improved liquid crystal display includes, in sequence from the viewing surface to the medial plane of the display, a substantially transparent polymeric layer, a polarizing layer, a protective layer, a transparent electrode layer, an alignment layer, and a layer of liquid crystal material. The use of a polymeric layer with a polarizing layer intermediate the polymeric layer and the liquid crystal material results in a relatively lower cost display in which the optical anisotropy of the polymeric material does not adversely affect the operation of the liquid crystal display.
