摘要：
A retardation film is provided and is formed by laminating a thermoplastic norbornene resin film, an anchor layer, an alignment film and a phase difference layer in this order. In this retardation film, the anchor layer is formed by applying an anchor material including a tri-, or more-functional acrylate monomer of 50 parts by weight or more and 90 parts by weight or less onto the thermoplastic norbornene resin film and then, drying and curing the anchor material with ultraviolet light.
