Abstract:
A display optical apparatus comprising:an illumination optical system, including a color separator, for emitting, as illumination light, light polarized uniformly in a predetermined polarization direction after separating it by the color separator in such a way that light components of different wavelength ranges travel in different directions; a light modulating device having a display surface on which an optical image to be illuminated with the illumination light is displayed, the display surface being composed of pixels corresponding to three primary colors, namely R, G, and B, arranged in a recurring pattern; a projection optical system for focusing projection light exiting from the light modulating device on an image plane; and pixel shifting means for shifting the projection light focused on the image plane by a predetermined number of pixels at a time, wherein the illumination light is composed of light beams of three primary colors, namely R, G, and B, arranged in a recurring pattern, with light beams of identical colors illuminating a plurality of adjacent pixels of corresponding colors on the display surface of the light modulating device.
