Abstract:
A light-diffusing film and screen including same are provided. The light-diffusing film having anisotropy in the diffusion angle includes a translucent support, and a translucent resin layer having irregularities on the surface thereof and being provided on the translucent support. In the light-diffusing film, the maximal value of the loss tangent (tan δ) determined from a dynamic viscoelasticity of the light-diffusing film lies in a temperature range of 0° C. to 60° C.
