摘要： A driving method for a spatial light modulator can provide bright image, images of high contrast and resolution with no persistence and instability, and can be used in a projection display system. The spatial light modulator is prepared by sandwiching a ferroelectric liquid crystal layer between a first substrate and a second substrate. The first substrate is prepared by sequentially laminating a transparent conductive electrode and a photoconductive layer with rectifying properties on a glass substrate. On the photoconductive layer, a reflective layer and an alignment layer for aligning a liquid crystal layer are then laminated. The second substrate is prepared by laminating a transparent conductive electrode and an alignment layer on a glass substrate. Alternating current voltage having a waveform of inconsistent cycles is applied to a section between the transparent conductive electrodes.

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.
