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.

摘要： A spatial light modulator and a neural network circuit are disclosed. The modulator is used in pattern recognition and has an arrangement in which a photoconductive layer held between conductive electrodes is connected in series to a liquid crystal cell including a liquid crystal layer held between two opposite electrodes. Setting the rate between the area of the photoconductive layer and the area of at least one of the opposite electrodes between which the liquid crystal layer is disposed, provides a highly efficient reflective and transmissive spatial light modulator of a simple structure. Both reflective and transmissive spatial light modulating elements are applied to a neurocomputer or the like.
