Abstract
Liquid crystal for a right eye and liquid crystal for a left eye are not positioned in one plane, but are positioned to incline at an angle of 5.degree.. To be concrete, both liquid crystal are inclined so that they become closer to the viewer's face as making toward the side of the face from the middle of the forehead. The inclination of liquid crystal as above-described to set the preferential direction of visual view of liquid crystal to be horizontal leads in that the direction by which the high contrast of liquid crystal can be obtained is toward the 3D display. It diminishes a phenomenon like cross-talk and allows the viewer to view the appropriate stereoscopic image. Liquid crystal for a right eye and liquid crystal for a left eye have the same construction. These liquid crystals make contrast with each other and then they are mounted on the liquid crystal shutter glasses portion. This makes it possible for each electrode to position in the center of liquid crystal shutter glasses portion. The construction in which the electric circuit is in the center of the liquid crystal shutter glasses portion makes it easy to make electric contact between the circuit and the electrode.
