ABSTRACT:
In a single panel color projection LCD, white light emitted from a light source is optically processed by an optical processing unit so as to convert three primary color beams obtained from the white light into predetermined polarized beams. All of the predetermined polarized beams may be P-polarized beams or S-polarized beams. Thereafter, the optical processing unit irradiates only the predetermined polarized beams onto the liquid crystal panel without an optical power loss. A color image which is given by the liquid crystal panel is projected onto a screen to be displayed in an enlarged form.
