Abstract
An anisotropic light diffusion film includes increased uniformity of the intensity of diffused light in the light diffusion angle region, and the light diffusion angle region has been effectively expanded. An anisotropic light diffusion film includes a first louver structure region and a second louver structure region, in which plural plate-shaped regions having different refractive indices are alternately arranged in parallel along any one direction along the film plane, sequentially from the lower side along the film thickness direction, and the anisotropic light diffusion film includes an overlapping louver structure region in which the upper end of the first louver structure region and the lower end of the second louver structure region overlap each other.
