ジエクタ。[Claims for Utility Model Registration] Light from the same light source is separated into a plurality of colored lights by a dichroic mirror, each of these colored lights is incident on a plurality of liquid crystal display panels, and each color is emitted from each liquid crystal display panel. In a liquid crystal projector that projects image light of each color onto a projection surface using a plurality of projection lenses provided correspondingly to each of the liquid crystal display panels, and superimposes the image light of each color on the projection surface to display full-color image light. , among the optical paths for guiding the light of each color separated by the dichroic mirror to each liquid crystal display panel, at least the optical path to the liquid crystal display panel having a short distance from the light source is a refracting optical path equipped with a mirror, and from the light source to the A liquid crystal projector characterized in that the lengths of each optical path to each liquid crystal display panel are approximately equal.
