PROBLEM TO BE SOLVED: To provide a photo-diffusive film that can improve front luminance of a surface light source device and the like, by having both high photo- permeability and efficient photo-diffusion, and also attain a low cost. SOLUTION: In this film, a laminate 9, in which a photo diffusive layer 8 of polyester resin composition containing acrylic resin grains laminated on one side of a transparent base film 7 is laminated, and an anti reflection layer 10 is laminated and formed on at least one side of the laminate 9. In this case, compounding amount of the acrylic resin grain to 100 weight polyester resin in the photo-diffusive layer 8 is set within 150-300 weight. |
