ABSTRACT:
A rear projection screen suitable for use as, for example, a screen for video projector. The rear projection screen is provided with a lenticulated surface at least one the viewer's side thereof. The lenticulated surface is constituted by a plurality of lenticule units each having total reflection surfaces on both inclined flanks thereof and a plurality of curved surface portions between both inclined flanks. The arrangement is such that a part of the light rays impinging from the projection side of the screen are reflected by the total reflection surfaces and then pass through the curved surface portions of each lenticule unit. Another type of lens may be formed between each of the adjacent lenticule units.
