Double-sided adhesive layer-equipped optical laminate

Abstract

There is provided an optical laminate with pressure-sensitive adhesive layers on both surfaces, which is suppressed damage from occurring to a low-refractive index layer in vacuum lamination while maintaining excellent characteristics of the low-refractive index layer. An optical laminate with pressure-sensitive adhesive layers on both surfaces according to an embodiment of the present invention comprises: a substrate; a low-retractive index layer formed on the substrate; a first pressure-sensitive adhesive layer arranged so as to be adjacent to the low-refractive index layer; and a second pressure-sensitive adhesive layer serving as one outermost layer. The low-refractive index layer has a porosity of 50% or more, the first pressure-sensitive adhesive layer has a storage modulus of elasticity of from 1.3×105 (Pa) to 1.0×107 (Pa), and the second pressure-sensitive adhesive layer has a storage modulus of elasticity of 1.0×105 (Pa) or less.
