When transferring a layer containing an optically anisotropic layer in an optical film to a transfer medium, the layer containing the optically anisotropic layer can be uniformly peeled from the substrate, and further, under high temperature drying conditions An optical film capable of suppressing a decrease in in-plane retardation value is provided. A step of applying a composition containing a polymerizable liquid crystal compound on an alignment film of a laminate having a substrate and an alignment film, and a step of irradiating active energy rays to the laminate on which the composition has been applied. The step of irradiating active energy rays includes irradiation of active energy rays twice or more, and the energy of active energy rays in the first active energy ray irradiation and the second time. The method for producing an optical film, wherein the ratio of the energy of active energy rays in the irradiation of active energy rays satisfies a specific range, and the energy of active energy rays in the second active energy ray irradiation is 10 to 10,000 mJ / cm 2. .
