Image display apparatus and optical compensation device

Abstract

An image display apparatus includes a liquid crystal panel having a liquid crystal layer disposed between a pair of substrates, and an optical compensation plate pair including a first optical compensation plate and a second optical compensation plate, the first optical compensation plate being formed of a negative uniaxial crystal and the second optical compensation plate being formed of a positive uniaxial crystal. The optical compensation plate pair is configured such that an optical phase difference caused by a difference in thickness between the first optical compensation plate and the second optical compensation plate cancels an optical phase difference generated by the liquid crystal panel.
