Projector and liquid crystal panel unit for use in projector

摘要

A projector includes: a liquid crystal panel 7 in which liquid crystal molecules to be irradiated with light from a light source 35 are sealed; a polarizing plate 73 disposed in a position to face the liquid crystal panel 7; and an optical compensation sheet 8 disposed between the polarizing plate 73 and the liquid crystal panel 7 and compensating birefringence of the liquid crystal molecules. The optical compensation sheet 8 can be adjusted by being swung in a plane orthogonal to the optical axis, and its normal can be adjusted so as to be tilted from the optical axis.
