Patent abstract
A color separator includes a polarization converting section for converting an incoming light ray into a linearly polarized light ray such that the polarization direction of the linearly polarized light ray is selectable from a number of predetermined directions, and a diffracting section, which is arranged so as to receive the linearly polarized light ray that has gone out of the polarization converting section and which produces a zero-order light ray in which one of multiple different wavelength components is selectively weakened according to the polarization direction at least.
