Liquid crystal device and projector including the same

Abstract

A liquid crystal device includes a liquid crystal cell containing liquid crystal operating in twisted nematic mode, a first compensating element disposed either on the light entrance side or on the light exit side of the liquid crystal cell and made of an optical material having positive uniaxial characteristics, a second compensating element disposed either on the light entrance side or on the light exit side of the liquid crystal cell and made of an optical material having positive uniaxial characteristics, a third compensating element disposed at least either on the light entrance side or on the light exit side of the liquid crystal cell and made of an optical material which satisfies the following condition for parameters Re and Rth concerning refractive index anisotropy: −Rth<Re<Rth, and a pair of polarizing elements between which the liquid crystal cell, the first compensating element, the second compensating element, and the third compensating element are disposed.
