Abstract
The front surface of a lens plate is worked into lenticules extending in the vertical direction. A reflective material is provided in the rear of the lens plate. Black stripes are vertically formed on the back surface of the lens plate such that their pitch is increased from the center toward the right and left edges of the screen so that incident light emitted from CRTs or a liquid crystal projector and reflected light from the reflective material pass between the black stripes.
