ABSTRACT:
A projector includes: an optical modulator including a liquid crystal cell, a first optical element formed of an optical material having positive uniaxiality, a second optical element formed of an optical material having positive uniaxiality, a third optical element including at least one optical film formed of optical material having a refractive index anisotropy, and a pair of polarization elements; an adjustment mechanism that can adjust an optical azimuth of a first group, having at least one of the first optical element, second optical element, and at least one optical film included in the third optical element, with respect to a fixed optical azimuth of a second group as a remainder excluding the element included in the first group among the first to third optical elements; a light source generating light for illuminating the optical modulator; and a projection optical system projecting the light passed through the optical modulator.
