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.

1. An optical modulator comprising:two-dimensional pixels; spectral means for diffracting white illumination light into bands of light of predetermined wavelength; a liquid crystal layer for modulating the intensity of the bands of light passing therethrough; condensing means for condensing the bands of light spectrally diffracted by the spectral means so as to direct the bands of light to corresponding two-dimensional pixels of the optical modulator; and reflecting means for each two-dimensional pixel for reflecting the light coming to the two-dimensional pixels through the liquid crystal layer in an incidence direction that is approximately the same as the reflection direction of the light reflected from the reflecting means, said reflecting means defining the two-dimensional pixel of the optical modulator.
