Abstract
An optical address type spatial light modulator has a plurality of optical address type light modulation layers stacked on each other, each having a liquid crystal layer for reflecting visible light in a specific wavelength band or a liquid crystal layer for absorbing visible light in a specific wavelength band and coloring and a photoconductive layer for absorbing the visible light in the specific wavelength band and changing the resistance value in response to the light intensity of the visible light absorbed, the liquid crystal layer and the photoconductive layer being stacked on each other between electrodes.
