Claim 27:
28. The 3D display device of claim 27, further comprising 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 each other,
wherein the final polarization conversion element is configured to receive the light of the first wavelength band, the light of the second wavelength band, and the light of the third wavelength band that are emitted from the third sub deflector, and to convert 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.
