All of first to third liquid crystal panels have the same structure. A plurality of dichroic mirrors separate light from a light source into the three primary color (red, green, and blue) beams, and cause the red, green, and blue beams to be respectively incident on the first, second, and the third liquid crystal panels. A dichroic prism superposes the red, green, and blue beams which are respectively transmitted through the liquid crystal panels. A projection lens projects a full-color image beam formed by the dichroic prism. Correcting devices are respectively arranged to oppose the incident surfaces of the first to third liquid crystal panels, and cause the respective color beams separated by the dichroic mirrors to be incident as beams in which the intensities of light components oscillating in the same direction are high.
