Abstract: A gas barrier film comprising a substrate layer containing a filler, an anchor coat layer provided on the substrate layer, and a gas barrier layer provided on the anchor coat layer. In the gas barrier film, an average particle diameter D of the filler is 0.02 to 3.00 μm, a thickness of the substrate layer is equal to or larger than the average particle diameter of the filler, and a total thickness T of one or more layers disposed between the substrate layer and the gas barrier layer is 0.02 to 0.40 μm.

Abstract: A first quantum dot protective film comprises a first barrier film including a silica deposition layer, and a first diffusion layer. An O/Si ratio of the silica deposition layer is 1.7 or more and 2.0 or less on an atomic ratio basis, and a refractive index of the silica deposition layer is 1.5 or more and 1.7 or less; and a reflectance of the first quantum dot protective film is 10% or more and 20% or less at each of wavelengths of 450 nm, 540 nm and 620 nm, and a transmittance of the first quantum dot protective film is 80% or more and 87% or less at each of wavelengths of 450 nm, 540 nm and 620 nm.
