摘要： Pixel portions of a photoconductive layer each have a pin structure for providing a rectifying function and are substantially electrically isolated from one another by a highly resistant inter-pixel portion for preventing diffusion of electrical carriers. Data written into a liquid crystal layer by writing light is read out as an optical output by reading light. Reflecting films are provided on the pixel portions, respectively, and an output light blocking film is provided on the inter-pixel portion formed into a groove. The reflecting films and the output light blocking film are partially overlapped on each other so as to sufficiently block the reading light.
