Abstract
A projector including at least one light source, a polarization separation element that separates light from the light source into two linearly polarized light beams whose polarization axes are orthogonal to each other to emit the two linearly polarized light beams in the same direction, a TIR prism that transmits through the two linearly polarized light beams, a reflective light modulation element that receives the two linearly polarized light beams that have been emitted from the TIR prism to modulate and reflect the two linearly polarized light beams toward the TIR prism, a projection lens that enlarges and projects the two linearly polarized light beams that have been modulated by the reflective light modulation element and that have been transmitted through the TIR prism, and a rotating prism being rotatably arranged in an optical path.
