ABSTRACT:
An illuminating apparatus includes a polarized light beam splitter, a first polarized light source device, and a second polarized light source device. The first polarized light source device has a first light source device, a first polarized light separation prism, and a first polarization element. The second polarized light source device has a second light source device, a second polarized light separation prism, and a second polarization element. The illuminating light flux having the first polarized light component emitted from the first polarized light source device and illuminating light flux having the second polarized light component emitted from the second polarized light source device are both linear polarized light components and have different polled light axis from each other. The polarized light beam splitter synthesizes the illuminating light flux having the first polarized light component emitted from the first polarized light source device and the illuminating light flux having the second polarized light component emitted from the second polarized light source device to emit.
