Claim 29:
30. A beam deflector comprising:
a first sub deflector configured to deflect light of a first wavelength band in a first direction and a second direction that intersects the first direction, and convert a polarization direction of the light of the first wavelength band;
a second sub deflector configured to deflect light of a second wavelength band, that is different from the first wavelength band in the first direction and the second direction, and convert a polarization direction of the light of the second wavelength band;
a third sub deflector configured to deflect light having a third wavelength band that is different from the first wavelength band and the second wavelength band, respectively, and convert the polarization direction of the light of the first wavelength band, the polarization direction of the light of the second wavelength band, and a polarization direction of the light of the third wavelength band; and
a final polarization conversion element configured to change the polarization direction of the light of the first wavelength band, the polarization direction of the light of the second wavelength band, and the polarization direction of the light of the third wavelength band to coincide with one another,
wherein the first sub deflector, the second sub deflector, and the third sub deflector are sequentially provided such that the light of the first wavelength band, the light of the second wavelength band, and light of the third wavelength band sequentially pass through the first sub deflector, the second sub deflector, and the third sub deflector.
