An optical projection apparatus includes an optical lighting system provided with a polarized beam splitter for polarizing a white light flux received from a white light source and combining the white light flux with other light fluxes, thereby taking out a predetermined polarized wave; a multi-lens array consisting of a plurality of lens elements; and an irradiator for separating the white light flux into three primary color light fluxes of red, green, and blue and irradiating each of the three color light fluxes on the same display element at an angle different from the others; and a projector for projecting the three primary color light fluxes modulated by the display element. The optical lighting system and the projector are disposed between the white light source and the display element.
