The valve comprises a photo conductive layer (4) the impedance of which is varied by input light, a birefringence layer which has an LCD for refracting input light, a shading layer (5) which consists of P-type amorphous silicon coated with boron and is located between the birefringence layer and the photo conductive layer, and electrodes which provide a birefringence part with a driving voltage.
