PROBLEM TO BE SOLVED: To improve mechanical strength by adding an additional transparent support layer to a translucent base material constituting a rear face projection rear screen (simply referred to as a transparent screen) and a transparent support layer having a lenticular lens array so that the sheet constituting the screen is made to be thick, and to reduce the amount of warpage and the amount of torsion, even when the warpage providing process is performed at a temperature near the softening point. SOLUTION: The lenticular sheet for use in the rear face projection rear screen is formed by sticking together the translucent base material layer 11 and the transparent support layer 16 having on the surface a lens array 17 consisting of lenticular lenses in which unit lenses of cylindrical lenses having the longitudinal direction in perpendicular one-dimensional direction are arranged in parallel in the horizontal direction, via an adhesive layer 14 at the back of the transparent support layer 16. The lenticular sheet also includes a second transparent support layer 13 between the translucent base material layer 11 and the transparent support layer 16. COPYRIGHT: (C)2006,JPO&NCIPI
