摘要： An optical element includes a dichroic surface formed by a multilayer dielectric film or the like and a polarized beam splitter surface formed by a multilayer dielectric film or the like. The dichroic surface transmits light (G and R) from a green wavelength band to a red wavelength band irrespective of the polarization directions of light, and reflects light (B) in a blue wavelength band. The polarized beam splitter surface reflects an S-polarized light (Gs) in a green wavelength band. Furthermore, the polarized beam splitter surface transmits an S-polarized light (Bs) and a P-polarized light (Bp) in the blue wavelength band, and also transmits the S-polarized light (Rs) and P-polarized light (Rp) in the red wavelength band.

摘要： An illumination apparatus includes a red light valve, a green light valve, a blue light valve, a polarization adjustment element, and a color combiner. The polarization adjustment element adjusts polarization of fourth color component light. The color combiner combines light emitted from the red light valve, the green light valve and the blue light valve. Superimposed component light which is any one of a red component light, a green component light and a blue component light enters the polarization adjustment element together with a fourth color component light. The polarization adjustment element transmits the superimposed component light without adjusting the polarization, and transmits the fourth color component light with adjusting the polarization. The superimposed component light and the fourth color component light emitted from the polarization adjustment element enter a specific light valve corresponding to the superimposed component light, among the red light valve, the green light valve and the blue light valve.
