Abstract

PURPOSE:To obtain a reflection type screen of a flat shape, and uniform luminance in picture quality by flatly arranging the plural strip parts which consist of surface reflection material and optical transmission bodies (optical media) into one piece and in which ray focusing effect and the directivity of ray diffusion extend in a small direction. CONSTITUTION:A resin member 11 of which one surface is plane and the other surface is provided with multiple strip parts 11a of >=1mm. width in such a way as to be adjacent to each other in the specific level difference is manufactured by molding a synthetic resin by pressure molding or the like. A surface reflection material (Al foil or the like) 12 having anisotropy in the diffusion directivity of reflected rays is affixed on the surface having said pats 11a. Or a resin member is provided with multiple strip parts 13a of <=1mm. width on one surface by providing level differences and a reflection material 12 is affixed on the flat surface of a lens member 13 of which the other surface is molded flat. Level differences 11, 13a are so set that the angle theta indicating the inclination of the parts 11a is expressed by the equation where the perpendicular down to the centerline O of the screen in H, the length from the strip parts up to the point H is (h) and a desired radius of curvature is R. In this way, sufficient luminances are provided within the range of visual angles and images are made visible with roughly uniform luminance.
