TRANSMISSION-TYPE SCREEN, METHOD OF PRODUCING THE SAME AND BACKSURFACE PROJECTION IMAGE DISPLAY USING THE SAME SCREEN

摘要

A transmission-type screen comprising a plurality of screen sheets, wherein a plurality of lenses for collecting light are arranged in succession on a plane of image light incidence of at least one screen sheet, the lenses are focused inside the sheet, and a light-absorbing layer is provided on a region where the image light near the focal point does not pass through, in order to decrease multiple reflection and reflection of external light among the screen sheets and to improve focusing characteristics and contrast of the image. Moreover, the center of the region where the image light passes through is nearly brought into agreement with the optical axis of the lens provided on the plane of image light incidence. A predetermined decentering quantity d is imparted to the end portions, and a Fresnel lens is provided on the outgoing plane.
