摘要： The present invention provides a laminated retardation plate that shows an excellent viewing angle property when used in a liquid crystal display, and that can be decreased in thickness. The laminated retardation plate is formed by laminating an optically anisotropic layer (A) made of a polymer having an in-plane retardation of 20-300 nm and a ratio between a thickness direction retardation and the in-plane retardation of not less than 1.0, and an optically anisotropic layer (B) made of a non-liquid crystalline polymer such as polyimide having an in-plane retardation of not less than 3 nm and a ratio between a thickness direction retardation and the in-plane retardation of not less than 1.0. The thus obtained laminated retardation plate shows excellent optical properties, e.g., an in-plane retardation (Re) of 10 nm or more, and a difference between a thickness direction retardation and the in-plane retardation of 50 nm or more.
