Abstract: An anti-reflective film-attached transparent substrate includes: a transparent substrate including two main surfaces; and a diffusion layer and an anti-reflective film on one main surface of the transparent substrate, which are provided in this order. The anti-reflective film-attached transparent substrate satisfies (A) a luminous transmittance is 20% to 90%, (B) a transmission color b* value under a D65 light source is 5 or less, (C) a luminous reflectance (SCI Y) of an outermost layer of the anti-reflective film is 0.4% or less, (D) a sheet resistance of the anti-reflective film is 104 Ω/square or more, (E) the anti-reflective film has a laminated structure in which at least two dielectric layers having different refractive indices are laminated, and (F) a Diffusion value is 0.2 or more and a diffused light brightness (SCE L*) is 4 or less.

Abstract: An anti-reflective film-attached transparent substrate includes a transparent substrate having two main surfaces and, on at least one of the main surfaces, a multilayer film in which at least two layers having different refractive indices are laminated. At least one silicon oxide layer among the layers in the multilayer film has a moisture permeability of 300 g/m2/day or less.
