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.
