A projector includes: a liquid crystal panel in which liquid crystal molecules to be irradiated with light from a light source are sealed; a polarizing plate disposed in a position to face the liquid crystal panel; and an optical compensation sheet disposed between the polarizing plate and the liquid crystal panel and compensating birefringence of the liquid crystal molecules. The optical compensation sheet 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.
