Abstract:
Provided is an antireflective-film attached transparent substrate having a luminous transmittance of 20% to 84% and a b* value of a transmission color being 5 or smaller under a D65 light source, in which the antireflective film has a luminous reflectance being 1% or lower and a sheet resistance being 104 Ω/□ or higher, and in which the antireflective film has a multilayer structure built up of at least two layers, at least one layer is constituted mainly of silicon oxide, and at least another layer is constituted mainly of a mixed oxide of at least one oxide of Mo and W and at least one oxide of Si, Nb, Ti, Zr, Ta, Al, Sn, and In, and has an extinction coefficient at 550 nm being in a range of 0.005 to 3.
