ロジエクタ。[Claim for Utility Model Registration] Light from a light source is irradiated onto a transmissive liquid crystal display panel attached to the front of a liquid crystal cooler filled with cooling liquid, and an image displayed on this liquid crystal display panel. In a liquid crystal projector that enlarges and projects images onto a screen using a projection lens, the liquid crystal cooler transmits light in a specific polarization direction of light from the light source incident from the rear surface, and transmits light in other polarization directions. A liquid crystal projector characterized by being equipped with a reflective beam splitter plate.
