Abstract
An optical laminate body including: a substrate; and an adhesive layer formed on substrate, wherein the optical laminate body is used such that a surface thereof on the adhesive layer side is attached to a glass-made light-emitting surface member, a relationship n3≧n2≧n1 is satisfied where n1 is a refractive index of the glass that constitutes light-emitting surface member, n2 is a refractive index of the adhesive layer, and n3 is a refractive index of the substrate, the adhesive layer is composed of an acrylic adhesive composition containing an acrylic resin (A), and the acrylic resin (A) is a copolymer of a copolymerizable component [I] containing 40% by weight to 93% by weight of an aromatic ring-containing monomer (a1), and 7% by weight to 60% by weight of a hydroxy group-containing monomer (a2), the weight average molecular weight of the acrylic resin (A) being 200,000 or less.
