摘要:
A liquid crystal display device includes: 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 the incident side of the liquid crystal panel to optically compensate the liquid crystal device; and a second optical compensating plate disposed on the exit side of the liquid crystal panel to optically compensate the liquid crystal device. A first retardation of the first optical compensating plate in system optical axis direction is larger than a second retardation of the second optical compensating plate in the system optical axis direction.
