ABSTRACT:
A projection-type display device using twisted nematic liquid crystal light valves having multi-twist and/or multi-polarization angles. The photoelectric transfer characteristics of three light valves are optimized for reflecting red, green and blue light with high efficiency and similar reflectivity by selecting proper twisted angle and polarization angle for each corresponding liquid crystal light valve. The twisted angle or polarization biasing angle of each light valve may be different.
