PROBLEM TO BE SOLVED: To provide a polarization color resolution optical system capable of performing color resolution and control of a polarization direction by the number of less parts while eliminating a loss in light quantity when it is used for a color liquid crystal projector. ;SOLUTION: The polarization color resolution optical system A is the polarization color resolution optical system color resolving incident light to three wavelength components of R, G, B, and emitting respective wavelength components as linear polarization, and is provided with first, second, third polarization color resolution elements 10, 20, 30 of a plane mirror type linearly arranged in order from a light source side. Respective elements are constituted of first, second reflection surfaces 11, 12 arranged at an opening angle of 120° and a polarization separation surface 13 arranged bisecting this opening angle, and the first, second reflection surfaces 11, 12 are intersected with the polarization separation surface 13 on a straight line, and this cross line makes a part of a ridgeline.;COPYRIGHT: (C)1998,JPO
