Bildanzeigegerät mit Rückprojektion

摘要

A rear projection type display system with a transmissive screen. A transparent reinforcing plate (11) is coupled to a lenticular sheet (5) of the screen on the light output side by a connective member (12) to broaden the horizontal diverging angle by 60 degrees or more to the right and left sides. The duty factor of a black stripe (7) formed on the lenticular sheet (5) is set to 60% or more so as to improve the contrast of an image. The diverging angle at each point of a vertically-diffusing lens (109) for diverging light in the vertical direction is modulated in accordance with the height of each point to offer a proper visual angle range in the vertical direction.
