1. An optical system, comprising:
a first optical system that includes a first optical element having a plurality of divided regions having mutually different polarization actions, the first optical element being disposed at a first pupil position in the optical system, wherein the first optical element generates illumination light including a plurality of color light beams in mutually different wavelength bands;
a plurality of light valves that each modulates at least one color light beam of the plurality of color light beams included in the illumination light; and
a second optical system that includes a second optical element having a plurality of divided regions having mutually different polarization actions, the second optical element being disposed at a second pupil position conjugate to the first pupil position, and on which the plurality of color light beams modulated by the plurality of light valves is incident,
wherein each of the plurality of divided regions in the first optical element and each of the plurality of divided regions in the second optical element are conjugate to each other.
