A gas barrier film having a light diffusion layer having high durability against heat and light, and a wavelength conversion film using the same, in addition to good light diffusion performance and light transmittance. The gas barrier film has a support, an inorganic layer and an organic layer on one side of the support, and a light diffusing layer containing a binder and a light diffusing agent on the other side, wherein the binder comprises an acrylic polymer as a main chain A graft copolymer having a acryloyl group terminated ester polymer or a urethane oligomer on its side chain, an acrylic polymer having methacrylate on its side chain, and an acrylic polymer having a polycarbonate group terminal A graft copolymer having a retin polymer or a urethane oligomer in its side chain. |
