Patent ID: 7236285

Claim:
An optical display device comprising a light source, an optical separator which separates light from said light source into a plurality of light beams each having a specified wavelength different from one another, a plurality of first light modulation elements which receive a plurality of said light beams respectively incident from said optical separator, an optical combiner which combines said light beams from said first light modulation elements, and a second light modulation element which receives light from said optical combiner, said optical display device modulating said light from said light source by said first light modulation elements and said second light modulation element to display an image, wherein: said second light modulation element is implemented as a reflective type light modulation element to generate a reflected light, and arranged so as to constitute an off-axis optical system in which a predetermined angle is formed between an optical axis of said light received by said second light modulation element and an optical axis of said reflected light emitted from said second light modulation element; and said optical display device further comprises an image transformation unit which applies distortion to the images to be formed by said first light modulation elements in correspondence to said predetermined angle.
