    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.
