Zusammenfassung:	PURPOSE:To improve a left and right separation degree on a screen and to clarify stereoscopic visibility in a rear projection type stereoscopic projection system. CONSTITUTION:In rear projection type projection for performing stereoscopic display based on binocular parallax, at least a pair of projectors provided with a projection lens for projecting video images, a Fresnel lens 3 provided with the coating thickness of the internal reflection prevention coating of visible region light beams in video light beams on a light emission side corresponding to the incident angle of the video light beams from the projectors and a lenticular lens 2 for dispersing the video light beams from the Fresnel lens 3 in horizontal and vertical directions are provided. Thus, compared to the Fresnel lens without AR coating, the left and right separation degree of several dB is improved and the stereoscopic visibility is raised.
