Patent ID: 7880838

Claim:
A projection display comprising: a light source emitting light; a liquid crystal panel encapsulating a vertical alignment mode liquid crystal between a first substrate and a second substrate which are opposite to each other, the liquid crystal panel modulating light emitted from the light source, a longer axis of a molecule of the vertical alignment mode liquid crystal tilted from the normal direction of the first substrate; a projection lens projecting light which is modulated by the liquid crystal panel; a first polarization plate placed on an optical path from the light source to the liquid crystal panel; a second polarization plate placed on an optical path from the liquid crystal panel to the projection lens; and an optical-compensation plate placed between the liquid crystal panel and the second polarization plate, the optical-compensation plate including; a plate-like base which is opposite to the second polarization plate, the plate-like base having a delay axis within a plane which is in parallel with a plate side of the plate-like base, the delay axis of the plate-like base is in parallel with a transparent axis of the second polarization plate; and a retardation plate formed on a surface of the plate-like base, in which each of major refractive indexes intersecting each other within a plane that is in parallel with the retardation plate, is different from each other among the major refractive indexes, the retardation plate which is opposite to the liquid crystal panel, a direction of a fast or slow axis within a plane of the retardation plate is different from a direction of the tilted longer axis in which the molecule of the vertical alignment mode liquid crystal is normally projected to the surface of the first substrate, and a direction of the transparent axis of the second polarization plate or a direction of a transparent axis of the first polarization plate.
