PURPOSE:To obtain a liquid crystal light valve which is provided with a sufficient function with a simple sturcture, by interposing a light shielding layer, which has plural transmission holes corresponding to picture elements, and plural reflective mirrors, which face to respective transmission holes through a light-transmittable insulating layer and are separated from one another, between a liquid crystal layer and a photoconductive layer. CONSTITUTION:When a voltage is applied across transparent electrodes 2a and 2b and a signal ray is projected to a photoconductive layer 9 through a transparent substrate 1b, the resistance of the photoconductive layer 9 in this projection part is reduced, and the value of the voltage applied to the corresponding part of a liquid crystal layer 3 is increased through a transmission hole 6, and the orientation direction of the liquid crystal existing in the corresponding area is changed. A projected image is formed in the liquid crystal layer 3, and the projection light is projected from the side of a transparent substrate 1a and is reflected by a mirror 8, thereby magnifying and projecting the image generated in the liquid crystal layer 3 onto a screen or the like. Troubles of the leakage of the signal ray to the side of the crystal layer 3 and the incidence of the pro- jection light to the photoconductive layer 9 are prevented by a light shielding layer 5 and mirrors 8. |
