Optical layered body, polarizer, and image display device

Abstract

It is an object of the present invention to provide an optical layered body having sufficient hardness as an optical layered body and exhibiting a good antiglare property. An optical layered body, comprising a light-transmitting substrate and a hard coat layer formed on the light-transmitting substrate, wherein the hard coat layer comprises two layers of a clear hard coat layer (A) and a hard coat layer (B), the hard coat layer (B) has a surface roughness on the outermost surface and satisfies 0.0010≦φ≦0.14 0.25≦θa≦5.0 in the case where Sm is defined as a mean spacing of profile irregularities; θa is defined as a mean inclination angle of profile irregularities; Rz is defined as a mean roughness of the surface roughness; and φ is defined as Rz/Sm, and the optical layered body has substantially no interface between the clear hard coat layer (A) and the light-transmitting substrate.
