PROBLEM TO BE SOLVED: To solve the problem in a translucent screen that when one of a Fresnel lens or a lenticular lens is formed in a plate shape and the other is formed in a sheet shape, the lens formed in the plate shape warps by absorption of moisture in air and thereby causes deterioration in image quality such as focal performance and distortion of an image or the like. SOLUTION: The translucent screen 1 comprises a Fresnel lens plate 2 formed in the plate shape and a lenticular lens sheet 3 facing the Fresnel lens plate 2 and a low moisture absorption coat material 11 is applied onto a surface of a side opposite to the lenticular lens sheet 3 of Fresnel lens plate 2.
