The problem of the present invention is to provide an optical film having an optically anisotropic layer with excellent durability, and to provide a polarizing plate and an image display device that use the optical film. This optical film is provided with at least an optically anisotropic layer, wherein the optically anisotropic layer is obtained by polymerizing a polymerizable liquid crystal composition that includes a prescribed liquid crystalline compound and a polymerization initiator, the density of the optically anisotropic layer is at least 1.20 g/cm 3 , and the crosslink density of the layer is at least 0.0016 mol/cm 3 . |
