Abstract:
1. A liquid crystal display device, comprising: a liquid crystal panel which has a liquid crystal device containing liquid crystal operating in twist nematic mode and a micro-lens array disposed adjacent to the liquid crystal device; a first optical compensating plate disposed on an incident side of the liquid crystal panel to optically compensate the liquid crystal device; and a second optical compensating plate disposed on an exit side of the liquid crystal panel to optically compensate the liquid crystal device, the first optical compensating plate and the second optical compensating plate being made of same inorganic substance, optical axis polar angles of the first and the second optical compensating plates with respect to system optical axis direction being set at an equal angle, and a thickness of the first optical compensating plate being larger than a thickness of the second optical compensating plate so that a first retardation of the first optical compensating plate in the system optical axis direction is larger than a second retardation of the second optical compensating plate in the system optical axis direction.
