Beschreibung
Zusammenfassung:	Provided are a barrier film having superior close adhesion to a phosphor layer when used for a wavelength conversion sheet, a wavelength conversion sheet having the barrier film, and a backlight and a display device including the wavelength conversion sheet. A barrier film for a wavelength conversion sheet, comprising: a barrier layer; and a primer layer, wherein the primer layer comprises a cured product of a polyurethane-based resin composition, and when a surface of an opposite side of the primer layer from the barrier layer is subjected to X-ray photoelectron spectroscopy to obtain a C1s spectrum, P2/P1 is 0.55 or more, where P1 is an area of a peak assigned to a C-C bond in the C1s spectrum and P2 is an area of a peak assigned to a C-O bond in the C1s spectrum.
