Abstract: An anti-reflective film-attached transparent substrate includes: a transparent substrate including two major surfaces; and a diffusion layer and an anti-reflective film on one major surface of the transparent substrate, which are provided in this order. (A) A luminous reflectance SCI Y of an outermost surface of the anti-reflective film-attached transparent substrate is 1% or lower. (B) The anti-reflective film has a lamination structure in which at least two dielectric layers having different refractive indices are laminated. (C) A ratio (SCE Y)/(SCI Y) of a diffuse reflectance SCE Y of the outermost surface of the anti-reflective film-attached transparent substrate to the luminous reflectance SCI Y of the outermost surface of the anti-reflective film-attached transparent substrate is 0.15 or higher.

Abstract: The present invention provides a laminate that can eliminate adsorption defects of a substrate caused by warping of the substrate and enables electronic devices to be manufactured at high yield. The present invention pertains to a laminate that is provided with a support base material, an adhesion layer, and a substrate in said order. The substrate is provided with a dielectric multilayer film in which dielectric layers having different refractive indexes are alternately laminated on an outer surface of the substrate. The substrate provided with the dielectric multilayer film is disposed on the adhesion layer such that the dielectric multilayer film adheres in a peelable manner to the adhesion layer.
