Abstract
An optical film, which includes a laminate of a base and a birefringent layer, and which is excellent in adhesiveness between the base and the birefringent layer, is provided. The birefringent layer is formed on the base by: coating a material of the birefringent layer on the base so as to form a coating film; stretching/shrinking the base so as to stretch/shrink the coating film; and solidifying the material of the coating film. The material is dispersed or dissolved previously in a solvent and coated in a form of solution, where the solvent used exhibits solubility with respect to the base, and in the coating step, the solvent is infiltrated into a part of the interior of the base, thereby obtaining an optical film with excellent adhesiveness between the base and the birefringent layer.
