Abstract
In a rear projection screen for a color television projector, having a plurality of lenticular lenses on one surface thereof, the contour of the cross-section of each lenticular lens is simply formed of a pair of linear portions and an arcuate portion interposed between the pair of linear portions. Thus, a mold for manufacturing the screen can be simply and readily machined so as to provide low cost screens, while the picture on the screen looks satisfactorily when viewed from various view points throughout a wide angle.
