摘要： An illumination apparatus includes a plate-like separation optical element having a dichroic surface and a PBS surface. The dichroic surface reflects green component light and transmits yellow component light. The PBS surface transmits P polarization component light and reflects S polarization component light. The separation optical element combines red component light entering from a certain direction and transmitted through the dichroic surface, with yellow component light entering from a different direction and reflected by the PBS surface, and leads a combined light towards a red liquid crystal panel. The separation optical element combines green component light entering from the certain direction and reflected by the dichroic surface, with yellow component light entering from the different direction and transmitted through the PBS surface, and leads a combined light towards a green liquid crystal panel.

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.
