ABSTRACT:
A liquid crystal device (22) is disclosed which employs a wire grid (24) as a polarizer, a mirror and an electric field electrode. A twisted nematic liquid crystal display device is described which employs the wire grid (24) in place of the rear electrode (15), polarizer (19) and mirror (20) to provide a display which is less complicated and has better contrast and resolution than that of prior art displays.
