Abstract:
A color image projection device comprising:a light source for generating substantially white light; a separation device for separating white light flux from the white light source into red, green, and blue primary color light fluxes and for deflecting the separated color light fluxes in different directions; a reflective liquid crystal display element, disposed to receive all of said separated color light fluxes from said separation device, for modulating the separated color light fluxes to form a color image; a lens unit disposed between the reflective liquid crystal display and the separation device to condense the separated color light fluxes from the separation device onto a plurality of pixels of the reflective liquid crystal display, said lens unit including a birefringent element; and a projecting device for projecting the separated color light fluxes modulated by the reflective liquid crystal display element.
