摘要

PROBLEM TO BE SOLVED: To provide an optical film that is unlikely to cause separation of a transparent polymer film from a birefringent layer and to cause variation in retardation of the birefringent layer.

SOLUTION: In the optical film, an adhesive layer is formed by applying a polyurethane-based resin solution on a transparent polymer film layer, the birefringent layer is formed by applying a non-liquid crystal polymer on the adhesive layer, thereby, a laminated film is formed and, further, the laminated film is subjected to a stretching treatment.
