ABSTRACT OF THE DISCLOSURE A liquid crystal device for direct display of analog information in images and patterns includes a layer of liquid crystal material sandwiched between a front and a back transparent plate. Transparent conducting films are applied to selected portions of the sides of both front and back transparent plates adjacent to the liquid material. A re- sistor network is provided electrically continuous with at least one of the transparent conducting films for impressing a voltage gradient transversely across the transparent con- ducting films so as to permit the selective, incremental reorientation of the liquid crystal material into the desired images and patterns.
