Abstract:
1. A video display apparatus, comprising: a light source unit for radiating a light beam; a polarization converter for matching the light beam, which is outputted by said light source unit, to one of a S polarized light beam and a P polarized light beam; an optical characteristics switching element for separating a polarized light beam, which is outputted by said polarizing converter, into a plurality of color light beams, condensing the plurality of color light beams at different positions, and sequentially moving the plurality of color light beams between the different positions; and a video display element, as light valve element, for forming an optical image with said plurality of color light beams, in accordance with a video signal; and wherein said plurality of color light beams outputted by said optical characteristics switching element are radiated at different areas of said video display element, and said plurality of color light sequentially move between said different areas of said video display element.
