Provided are: a gas barrier film with a light diffusion layer, which has high durability in terms of heat and light, while having good light diffusion performance and light transmissivity; and a wavelength conversion film which uses this gas barrier film. This gas barrier film comprises: a supporting body; an inorganic layer and an organic layer, which are arranged on one surface of the supporting body; and a light diffusion layer which is arranged on the other surface of the supporting body and contains a binder and a light diffusing agent. The binder contains: a graft copolymer which has an acrylic polymer as the main chain, while having a urethane polymer or urethane oligomer having a terminal acryloyl group as a side chain; an acrylic polymer which has a methacrylate as a side chain; and a graft copolymer which has an acrylic polymer as the main chain, while having a urethane polymer or urethane oligomer having a terminal polycarbonate group as a side chain. |
