    摘要: A phase retarder film comprising a layer of polyvinyl alcohol or a derivative thereof and a water-swellable layered inorganic compound, wherein the in-plane retardation value is smaller than the retardation value in the thickness direction, sometimes causes durability failures, that is, the layer is peeled off from a transparent resin substrate in high temperature and high humidity environment. Therefore, the present invention provides a phase retarder film which is superior in durability.With respect to a phase retarder film comprising at least one layer containing at least one organic clay compound which can be dispersed in an organic solvent, wherein the in-plane retardation value is smaller than the retardation value in the thickness direction, the durability is remarkably improved.
