Abstract

Provided is an optical laminate excellent in antireflection function despite including a substrate having optical anisotropy (hereinafter sometimes referred to as "anisotropic substrate"). The optical laminate of the present invention includes, in this order: a polarizing plate including a polarizer and a protective layer arranged on at least one side of the polarizer; a first retardation layer; a second retardation layer; a conductive layer; and a substrate, wherein the substrate has an in-plane retardation Re(550) of more than 0 nm, and wherein an angle formed by a slow axis of the substrate and a slow axis of the second retardation layer is from -5° to 5° or from 85° to 95°.
