PROBLEM TO BE SOLVED: To provide a high contrast image by realizing a black level less in brightness unevenness and color unevenness without causing unnecessary double refractive action due to thermal stress. SOLUTION: This polarized light splitter is composed of a prism member, an optical coupling liquid of which the refractive index is matched with that of the prism member, and a polarized light splitting layer, and a part of the prism is provided with a plurality of air gap structure to be filled with the optical coupling liquid, to reduce disturbance of the state of the polarization plane by stress strain and double refractive action.
