ABSTRACT OF THE DISCLOSURE A light addressed liquid crystal light valve has two optically different states switchable therebetween by bias voltage in response to incident light. A ferroelectric liquid crystal layer is sandwitched by a pair of front and rear alignment layers to establish the two stable states in the ferroelectric liquid crystal layer. A front electrode layer is disposed on the front alignment layer. A dielectric mirror is disposed on the rear alignment layer. A phtoconductive layer is disposed on the dielectric mirror and responsive to the incident light incident from the rear face of light valve to increase its electroconductivity. A barrier metal layer is disposed on the photoconductive layer and forms a Schottky diode by combining with the photoconductive layer. A rear electrode is disposed on the barrier metal layer and is divided into a plurality of sub-electrodes to apply various bias voltage on the ferroelectric liquid crystal layer to thereby control a light writing sensitivity of the light valve according to the intensity distribution of a writing light.
