PROBLEM TO BE SOLVED: To provide a screen for projection hardly depending on a viewer's position with the brightness and color of an image , and having a high light use efficiency. SOLUTION: This screen for projection has a reflecting sheet 10 formed of a polyester resin foaming sheet 11 with an air-bubble average diameter of 12μm or shorter. The air bubbles are elliptic air bubbles having orientation, and the major axes of the elliptic air bubbles are substantially parallel to the lateral direction of a projected image projected on the reflecting sheet. The reflecting sheet is formed by planarly arranging a plurality of polyester resin foaming sheets. COPYRIGHT: (C)2009,JPO&INPIT
