Wavelength conversion film
Provided is a wavelength conversion film that suppresses a deterioration of quantum dots by oxygen and is capable of suppressing a decrease in brightness. The wavelength conversion film includes a wavelength conversion layer and auxiliary layers sandwiching the wavelength conversion layer, in which the wavelength conversion layer has polyvinyl alcohol and cured substance particles of a (meth)acrylate compound including wavelength conversion particles, and an oxygen permeability of the auxiliary layer is 1.0×10 0 to 1.0×10 −2 cc/(m 2 ·day·atm).
