发明名称 STEREOSCOPIC PICTURE DISPLAY DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a stereoscopic picture display device capable of preventing the unevenness of shading from occurring on a displayed stereoscopic picture. SOLUTION: Two parabolic mirrors, that is, a lower parabolic mirror 11 and an upper parabolic mirror are formed to be rotationally symmetric with respect to an optical axis X passing through each center 11o or 12o, and have the shape of the parabolic mirror. The two parabolic mirrors, that is, the lower parabolic mirror 11 and the upper parabolic mirror are oppositely arranged in a state where the optical axes X are aligned. An aperture part 13 is provided on the mirror 12 and covered with a transparent member 14. An illuminator 15 is constituted of a light source 15a and a cover part 15b, and attached along the inner periphery of the vicinity of the bonding part of the two parabolic mirrors. It is good to make the illuminator 15a ring type illuminator where the optical axes of the two parabolic mirrors are set as center and also good to cover the aperture part 13 with a half mirror instead of the member 14 and turn on or off the illuminator 15.
