Electro-optical device and method of operating same

Abstract

An electro-optical device, provided with a liquid crystal layer and a photoconductive layer, for converting a light input image into a projection image is characterized in that (A) a shading layer having a plurality of penetrating holes corresponding to picture elements and (B) a plurality of reflectors, separate from one another, facing the penetrating holes one by one through a light-transmittable insulating layer being contact with the shading layer are laid between the liquid crystal layer and the photoconductive layer. An electro-optical device comprising a liquid crystal layer is provided with counter electrodes at least one of which is composed of plural stripes of electrodes. In the devices, images can be produced by applying a voltage in the opposite direction of rectification with applying a writing light input signals and erased by applying a voltage in the forward direction of rectification.
