Abstract
In order to make it possible to effectively suppress interference fringes which occur due to the difference in refractive index between a retardation layer and a pattern alignment layer while maintaining an alignment property in a retardation film, a retardation film includes a substrate, an alignment layer containing a photo-alignment material, and a retardation layer containing a liquid crystal compound, and the alignment layer contains 3.0-8.0 parts by mass (inclusive) of epoxy monomer with respect to 100 parts by mass of photo-alignment material.
