Beschreibung
Zusammenfassung:	Provided is a barrier film that can suppress a change in color when applied to a wavelength conversion sheet. A barrier film for a wavelength conversion sheet, comprising an inorganic oxide layer A, an organic coating layer B, an inorganic oxide layer C, and a primer layer D in presented order on a light-transmitting base material, wherein thicknesses of the light-transmitting base material, the inorganic oxide layer A, the organic coating layer B, the inorganic oxide layer C, and the primer layer D are defined as t0, tA, tB, tC, and tD, respectively; tB is 150 nm or more and 500 nm or less; and tD/tB is 0.55 or more and 1.65 or less.
