Abstract:
1. A liquid crystal display system comprising: a liquid crystal device configured to optically modulate a light beam emitted through a liquid crystal layer with vertically aligning liquid crystal molecules which have a negative dielectric constant anisotropy and have a pretilt with respect to a direction vertical to a main surface of a substrate of the liquid crystal device; a first polarizer arranged on a light incident side of the liquid crystal device; a second polarizer arranged on a light emission side of the liquid crystal device; a pre-polarizer arranged between the light emission side of the liquid crystal device and a light incident side of the second polarizer; an optical compensator arranged in a light path between a light emission side of the first polarizer and the light incident side of the second polarizer; and a rotation portion to rotate the optical compensator and capable of rotating the optical compensator in the plane of the optical compensator, wherein,
