Patent ID: 6885422

Claim:
A liquid crystal display projector apparatus for projecting an image on a screen, said apparatus comprising: a liquid crystal panel having microlenses for focusing incoming light bundle on effective display area portions of pixels, the liquid crystal panel having an alignment of a plurality of twisted liquid crystal molecules; a polarizer for allowing linearly polarized light, which is contained in light emitted from a light source, to enter into the liquid crystal panel; an analyzer for allowing linearly polarized light, which is contained in light exiting from the liquid crystal panel, to enter into a projection optical system, the analyzer having a polarization axis perpendicular to a polarization axis of the polarizer; and a single optical compensator for compensating for an optical phase difference caused by liquid crystal molecules having pretilt angles in a light entry side of the liquid crystal panel, said single optical compensator being located between the liquid crystal panel and the analyzer thereby receiving a light through the microlenses, wherein a rotational angle of said optical compensator is selected so as to provide the best contrast of the image projected on the screen generated by said incoming light bundle having an incident angle in a range of 10 degrees to 15 degrees.
