<P>PROBLEM TO BE SOLVED: To provide a technique capable of easily and inexpensively manufacturing passive type 3D projector screens that can suppress a crosstalk rate to low, have a wide view angle, retain the brightness and be appreciated by a large number of persons. <P>SOLUTION: The surface of a screen substrate is embossed to be formed into an asperity surface, and a reflective coat is applied and formed on the asperity surface. Especially, the substrate having the asperity surface by embossing is a projection screen substrate usable as a 2D diffusion type projection screen, and the reflective coat is applied and formed on the asperity surface of the projection screen substrate. The projection screen manufactured by the manufacturing method has the surface of the coat-formed reflective coat that has undulation reflecting the asperity surface of the embossing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
