Abstract

PURPOSE: To increase contrast, make images even, bright and long lasting and further make them suitable for color displaying by constituting the light valve of the construction wherein it is integrated with a photoconductive layer and yet modulating voltages are space periodically applied to the liquid crystal layer.
CONSTITUTION: Metal stripe form thin films 35 of 20μ pitch are formed on a glass substrate 34 deposited with a transparent electrode 33 and a dielectric mirror 38 composed of a CdS photoconductive thin film 36, CdTe light shield layer 37 and multilayer films of TiO2 and SiO2 is laminated thereon. A positive nematic liquid crystal layer 41 of homogeneous orientation is sealed by way of a spacer 42 between this substrate 34 and a glass substrate 40 deposited with a transparent conductive film 39, whereby the liquid crystal light valve is constituted. Two-dimensional images for writing are formed in the thin film 36 and the applied voltages having two dimensional distributions to be applied between the electrode 33 and film 39 are modulated spacially at a fixed period, whereby the diffracted light having specific angles is produced and is projected as output images by a schlieren projection system.
