A phase difference film and a production method therefore which are controlled in the orientation direction of a phase difference layer with a high accuracy and are low in production costs. Referring to Fig. 1, a base material-carrying anisotropic layer (12) in which an optically anisotropic layer (11) is laid on a transparent base material (10) is provided. Next, a liquid containing a polymer and a liquid crystal compound that react to a polarized ultraviolet ray is applied onto the optically anisotropic layer (11) and dried. Then a polarized ultraviolet ray is applied to orient the liquid crystal compound, and, as required, a non-polarized ultraviolet ray is applied to cross-link the liquid crystal compound, whereby a phase difference film (1) having a phase difference layer (13) directly formed on the optically anisotropic layer (11) is produced.
