The retardation film of the present invention, and having a ring structure in its main chain (meth) acrylic polymer including 30 to 95% by weight, the layer made of resin composition comprising a cellulose ester polymer 5 to 70% by weight. In addition to the retardation film of the present invention, the photoelastic coefficient and the water vapor permeability is low, a high degree of freedom of wavelength dispersibility of the control of the phase difference, for example, of the wavelength of the phase difference inverse represents an acid, or the retardation wavelength dispersion is flat retardation a film. The retardation film is suitable for use of the optical compensation of the image display devices such as liquid crystal display devices (LCD).
