Photoconductive-type liquid crystal light valve with a shielding layer made of manganese oxide and silicon dioxide
 A photoconductive-type liquid crystal light valve having a shielding layer achieves a high resolution since shielding layer has both a high impedance and a high light-shielding property. The liquid crystal light valve comprises: a pair of transparent substrates disposed parallel to each other as a writing side and a reading side; a pair of transparent electrodes of a writing side and a reading side layered on inner side walls of the transparent substrates respectively to be face to face with each other; a photoconductive layer, a light shielding layer, a reflecting layer and a liquid crystal layer which are layered in sequence from the writing side to the reading side between the transparent electrodes, wherein the light shielding layer is made of a mixture of manganese oxide and silicon dioxide dispersed each other.
