Patent ID: 7030951

Claim:
A liquid crystal display projector comprising: a light source for emitting light required for image display; a transmission type liquid crystal display device including: a liquid crystal layer having an alignment of a plurality of twisted liquid crystal molecules; and means for selectively applying a voltage to the liquid crystal layer in response to an image signal, thereby realigning the liquid crystal molecules and thus modulating light passing through the liquid crystal layer; a projection lens for projecting the light modulated by the liquid crystal display device; a polarizer for allowing linearly polarized light, which is contained in light emitted from the light source, to enter into the liquid crystal display device; an analyzer for allowing linearly polarized light, which is contained in light exiting from the liquid crystal display device, to enter into the projection lens; a plurality of micro lenses, located between the polarizer and the liquid crystal layer, for focusing said light emitted from said light source onto said liquid crystal layer; and a first optical compensator for compensating for an optical phase difference caused by liquid crystal molecules in a light-entry-side of the liquid crystal layer, said first optical compensator being located between the liquid crystal display device and the analyzer on a light-exit-side of the liquid crystal display device and having birefringence of opposite sign to the birefringence of the liquid crystal layer.
