发明名称 Optical layered body, polarizer and image display device
摘要 Provided is an optical layered body that includes a polyester base, a primer layer formed thereon, and a hard coat layer formed on the primer. The polyester has a retardation of not less than 8000 nm, and a difference (nx−ny) of 0.07 to 0.20 between a refractive index (nx) in a slow axis direction that is a high refractive index direction and a refractive index (ny) of a fast axis direction that is orthogonal to the slow axis direction, a refractive index (np) of the primer, the refractive index (nx) in the slow axis direction of the polyester, and the refractive index (ny) in the fast axis direction of the polyester satisfy ny<np<nx, and a refractive index (nh) of the hard coat, the refractive index (nx) in the slow axis direction of the polyester, and the refractive index (ny) in the fast axis direction of the polyester satisfy ny<nh<nx.
