ABSTRACT:
The objective of the present invention is to provide a laminated phase retarder film that is superior in evenness, exhibits a biaxial optical property as a whole, and makes it possible to set the biaxial optical property over a wide range. This object is achieved by a laminated phase retarder film comprising a transparent resin film as a substrate and at least one coat layer having a refractive-index anisotropy laminated on at least one surface of the substrate, wherein a in-plane retardation value (R0) is not less than 20 nm, a retardation value (R′) in the film-thickness direction, which is calculated from a retardation value (R40) measured by inclining by 40 degrees around the slow axis of the film and the in-plane retardation value (R0), is greater than 40 nm.
