1. A liquid crystal display comprising:
- a first substrate plate and a second substrate plate, each plate having an inner surface and an outer surface;
a polarizing coating disposed overlying the inner surface of each plate, the polarizing coating formed from a lyotropic liquid crystal solution comprising one or more organic dyes selected from the group consisting of molecules where M is a cation and having Structure I where n=2, 3, or 4, Structure II, where n=2, Structure III where n=2 or 3, Structure V, where n=2, 3, or 4, Structure VI, where n=2, Structure VII where n=2, Structure VIII where n=2 or 3, Structure IX where n=2 and R=H, Cl, Alk, or OAlk, Structure X where n=2, X=O, NH, or CH2 and R=H, Cl, Br, OAlk or NHR′
, and Structure IV where n=1, 2, or 3, R=H or CF3, X=H, Br, or SO3M and R′
=H, (b), or (c); and
a liquid crystal layer disposed between the inner surface of the first plate and the inner surface of the second plate.

Abstract
A liquid crystal display has a first substrate plate and a second substrate plate, and a liquid crystal layer disposed between the plates. A polarizing coating, having molecules of one or more organic dyes capable of forming a lyotropic liquid crystalline phase, is formed overlying a selected surface of each plate. Orientation of the polarizing coating is obtained by applying a force to the dye molecules when in the liquid crystal phase and subsequently converting the liquid crystal phase to a solid film.
