PURPOSE: To provide a stereoscopic display device eliminating the need of glasses, etc., and without causing a contradiction in focal distance adjustment by controlling a focal distance of a focal distance variable lens and light deflection of a light deflector matching the timing of a display in each pixel of a display device. CONSTITUTION: The focal distances of the focal distance variable lenses 1a2, 1a3 are varied matching the displays of the pixels 1a5, 1a6 of a plane display device 1a1 by a control signal generator 1a4. In such a manner, an angle 1a7 equivalent to an image/eye stereoscopic angle is nearly equalized to the image/ eye stereoscopic angle at a position of an image 1a8 to be displayed. Further, deflection angles in the parts of the light deflector 1a10 corresponding to the pixels 1a5, 1a6 are varied matching the displays of the pixels 1a5, 1a6 of the plane display device 1a1. Thus, a parallax and a congestion angle 1a11 are equalized to the same caused at the position of the image 1a8. |
