Patent ID: 8431219

Claim:
An optical layered body, comprising a light-transmitting substrate and an antiglare layer having a surface roughness on its surface, wherein said antiglare layer is a resin layer containing an organic particle and a nonspherical silica, and a weight ratio of organic particle/nonspherical silica from 7/10 to 35/10 and the antiglare layer contains two kinds of organic particles, wherein the antiglare layer contains two kinds of nonspherical silica having different average particle size, wherein each of said two kinds of nonspherical silica having different average particle size have an average particle size of 0.5 to 5 μm, respectively, and wherein the surface of said antiglare layer satisfies the following: θa is 0.2° or more and 1.5° or less, Rz is 0.3 μm or more and 1.2 μm or less, Sm is 30 μm or more and 101.1 μm or less, wherein θa represents a mean angle of inclination of the surface roughness at the outermost surface layer of the optical layered body, Rz represents a ten-point mean roughness of the surface roughness and Sm represents a mean spacing of surface roughness at the outermost surface, and wherein the layer thickness of the antiglare layer is 1 μm to 10 μm.
