ANISOTROPIC LIGHT-DIFFUSING FILM, ANISOTROPIC LIGHT-DIFFUSING FILM WITH ADHESIVE LAYER, AND IMAGE DISPLAY DEVICE

An anisotropic light-diffusing film according to an aspect of the present invention has at least one first layer capable of scattering incident light in the traveling direction of the light, and the ratio (60 degrees brightness ratio / front brightness ratio) between a 60 degrees brightness ratio and a front brightness ratio which are obtained by the following methods is 0.30-0.60 inclusive. <60 degrees brightness ratio> In the light-diffusing film, the ratio (C/B) between a brightness C in a direction inclined at 60 degrees in a light diffusion direction from the direction of a normal N to a film surface and a front brightness B in the direction of the normal N to the film surface is defined as the 60 degrees brightness ratio. <Front brightness ratio> The ratio (B/A) between the front brightness B of the light-diffusing film and a front brightness A in the direction of a normal...
