PROBLEM TO BE SOLVED: To provide a light-diffusing adhesive layer that is an optical member to be used as an alternative to a conventional light-diffusing plate, has a function of light-diffusing sheet, and can reduce thickness of a display, and a light-diffusing adhesive film using the light-diffusing adhesive layer.SOLUTION: The light-diffusing adhesive layer has a light-diffusing function and is formed from an adhesive composition comprising the following copolymer, a crosslinking agent, and silicon-based particles. The copolymer comprises at least one kind of alkyl (meth)acrylate monomer having a 1-14C alkyl group and at least one monomer, as a copolymerizable functional group-containing monomer, selected from the group consisting of a hydroxyl group-containing copolymerizable monomer, a carboxyl group-containing copolymerizable monomer, a nitrogen-containing vinyl monomer, and an aromatic group-containing monomer. The light-diffusing adhesive layer has a transmittance of 90% or more, a haze value of 40% or more, and a refractive index of 1.47 or more. |
