A projector includes: a light source which emits light; a light modulating device which modulates the light emitted from the light source according to image information; an image forming system which forms an image corresponding to the optical image formed by the light modulating device of modulated light which is modulated by the light modulation device at an image forming position; a polarized light emitting unit disposed at the image forming position of the image forming system to selectively convert the polarization direction of a part of entering light; and a projecting device which projects the light from the polarized light emitting unit.
