ABSTRACT:
In a spatial light modulator used in a projection type display, holographic television set or the like and having a configuration of at least a photo-conductive layer with rectification and a ferroelectric liquid crystal layer provided between a pair of transparent electrodes and a side of the photo-conductive layer facing to a CRT, plural units of driving signals including at least an erasing pulse and a writing voltage period are applied between the transparent electrodes in one frame cycle of the CRT.
