Abstract:
Provided are an optical diffusion film composed of a single layer, for which the optical diffusion incident angle region can be effectively expanded, and even when the incident angle of incident light is varied within the optical diffusion incident angle region, changes in the optical diffusion characteristics can be effectively suppressed; and a method for manufacturing the optical diffusion film. Disclosed is an optical diffusion film having, inside the film, a single optical diffusion layer having a first internal structure and a second internal structure, each of which include a plurality of regions having a relatively high refractive index in a region having a relatively low refractive index, sequentially from the lower part along the film thickness direction, and the regions having a relatively high refractive index in the first internal structure have a bent section at an intermediate point along the film thickness direction.

Claim (Index 18):
A method for manufacturing an optical diffusion film according to  claim 12 , the method comprising the following steps (a) to (d):\n (a) a step of preparing a composition for an optical diffusion film including at least two polymerizable compounds having different refractive indices, a photopolymerization initiator and an ultraviolet absorber, in which the content of the ultraviolet absorber is adjusted to a value of below 2 parts by weight (provided that 0 parts by weight is excluded) relative to the total amount (100 parts by weight) of the at least two polymerizable compounds having different refractive indices; (b) a step of applying the composition for an optical diffusion film on a process sheet, and forming a coating layer; (c) a step of subjecting the coating layer to first irradiation with active energy radiation to form a louver structure as a first internal structure formed by bending an intermediate point along a film thickness of a region having a relatively high refractive index in the lower portion of the coating layer with the ultraviolet absorber, and also leaving a region where an internal structure is not formed, in the upper portion of the coating layer; and (d) a step of subjecting the coating layer to second irradiation with active energy radiation to form a louver structure as a second internal structure in the region where an internal structure is not formed.
