ABSTRACT:
An illuminator includes a light source that outputs light, a polarization separation device that separates the light outputted from the light source into polarization components of the first and second oscillation directions, the polarization components having mutually orthogonal polarizations, and a polarization conversion device that converts the polarization component of the second oscillation direction divided by the polarization separation device to the polarization component of the first oscillation direction. The polarization component of the first oscillation direction divided by the polarization separation device and the polarization component of the first oscillation direction converted by the polarization conversion device are incident on an incident surface of an illumination target from different directions from each other.
