Abstract
An optical modulator has a spectral means for diffracting white illumination light into light of predetermined wavelength bands, a liquid crystal layer for modulating the intensity of the light entering a plurality of two-dimensional pixels, a condensing means for condensing the light spectrally diffracted by the spectral means so as to direct the light to each pixel of the liquid crystal layer, and a reflecting means for reflecting the light that passes through the liquid crystal layer in approximately the same direction as the entering light.
