Abstract

PURPOSE: To make possible the magnified projection of color images with a single light valve by specifying the constitution of the light valve.
CONSTITUTION: The light valve is formed by subsequently arraying and laminating color filters 2W4 which selectively transmit wavelengths of R, G, B, a transparent conductive film 5, photoconductive film 6, light absorbing film 7 and dielectric mirrors 8W10 which selectively reflect the wavelengths of R, G, B in correspondence to the color filters 2W4 on one glass substrate 1, depositing a transparent conductive film 12 on the other glass substrate and disposing a nematic liquid crystal layer 13 having negative dielectric anisotropy between the both substrates 1, 11 and is disposed between a write lens 15 and a projection lens 20. If with this arrangement the color images from a color Braun tube 14 are formed on the photoconductive film 6 of the light valve 16 and the light of a projection light source 17 is entered to the light valve 16 followed by application of voltage, then the scattered light components of the liquid crystal layer 13 are selectively reflected and the color projected images are formed on a screen 21.
