Patent ID: 7551250

Claim:
A liquid crystal display device, comprising: a liquid crystal panel having a pair of substrates and a twisted nematic liquid crystal layer interposed between the pair of substrates, the liquid crystal panel having a light-entry side and a light-exit side; a light source applying light to the light-entry side of the liquid crystal panel; a first optical compensating plate disposed at the outside of the substrate at the light-entry side of the liquid crystal panel, the first optical compensating plate including hybrid-aligned liquid crystal molecules having a negative birefringence property, the first optical compensating plate having a fast axis as seen in a normal direction that is normal to the first optical compensating plate; a second optical compensating plate disposed at the outside of the substrate at the light-exit side of the liquid crystal panel, the second optical compensating plate including hybrid-aligned liquid crystal molecules having a negative birefringence property, the second optical compensating plate having a fast axis as seen in the normal direction, the fast axis of the second optical compensating plate intersecting the fast axis of the first optical compensating plate at an angle other than a right angle; and wherein one optical compensating plate of the first optical compensating plate and the second optical compensating plate is disposed such that the fast axis direction thereof is different from an alignment control direction of the substrate corresponding to the one optical compensating plate.
