ABSTRACT:
A diffusion film includes a transparent substrate and a diffusion layer. The diffusion layer shows a specific scattered light profile measured by a goniophotometer. In the scattered light profile, a ratio of an intensity of scattered light at an angle of 30° to an intensity of transmitted light at an angle of 0° is 0.01 to 0.2%.
