PURPOSE:To see a stereoscopic picture with a wide visual angle without using glasses by controlling variable focal length of fine convex lens groups corresponding to picture elements according to the picture element information. CONSTITUTION:Lens groups 2 of an LC fine convex lens 4 corresponding to a picture element of a display 1 are disposed in opposition to a display picture 1A of the liquid crystal display 1 and a picture light passing through the groups 2 is enlarged by a convex lens 3. In this lens 4, the focal length is controlled according to a depth information voltage of the graphic three dimensional information through a computer and a three dimensional stereoscopic picture capable of seeing with a wide visual angle without using glasses is formed. |
