1. An optical address type spatial light modulator comprising a plurality of optical address type light modulation layers stacked on each other,
wherein each of optical address type light modulation layers comprises:
a liquid crystal layer for absorbing visible light in a specific wavelength band to color; and
a photoconductive layer for absorbing the visible light in the specific wavelength band to change a resistance value in response to the light intensity of the visible light absorbed,
wherein each of the liquid crystal layers and each of the photoconductive layers are stacked on each other,
wherein the specific wavelength bands of the optical address type light modulation layers are different from each other,
wherein write light carrying an image is incident on a surface side to write the image, and
wherein read light for image read is incident on the surface side.
