摘要：PROBLEM TO BE SOLVED: To provide a projector screen improved in a visual angle and luminance. SOLUTION: This screen includes a Fresnel lens 21 changing incident light passing through the projection lens of a light projecting device into parallel beams, a lenticular lens 22 diffusing the parallel beams passing through the lens 21, and a protective panel 23 integrally formed with the lens 21. Since the range of a light diffusing angle is drasticaly widened, horizontal and vertical visual angles are made wider than the screen having conventional structure, and external light is reflected by the light diffusing surface of the panel 23, whereby the luminance is improved. Since a black stripe need not be formed on the lens 22, cost is reduced and productivity is improved.
