Claim:
1. A composition for light diffusion film, for obtaining a light diffusion film, which contains an internal structure including plural regions having a relatively high refractive index in a region having a relatively low refractive index within the film and in which the plural regions having a relatively high refractive index are bent at an intermediate point along the film thickness direction, the composition for light diffusion film comprising a (meth)acrylic acid ester containing plural aromatic rings as component (A), a urethane (meth)acrylate as component (B), a photopolymerization initiator as component (C), and an ultraviolet absorber as component (D), wherein a content of the component (A) is adjusted to a value within a range of 25 parts to 400 parts by weight relative to 100 parts by weight of the component (B), a content of the component (C) is adjusted to a value within a range of 0.2 parts to 20 parts by weight relative to the total amount, taken as 100 parts by weight, of the component (A) and the component (B), and a content of the component (D) is adjusted to a value of below 2 parts by weight relative to the total amount, taken as 100 parts by weight, of the component (A) and the component (B).
