    • The present invention provides a retardation film which can remarkably improve the controllability of retardation, and can also sufficiently control the wavelength dependency of retardation. The retardation film of the present invention can achieve a widening of the viewing angle at a high degree, when it is applied to a liquid crystal display device. Further, the present invention provides a laminated polarizing which comprises the retardation film and enables widening the viewing angle. Furthermore, the present invention provides a liquid crystal display device having high performance, especially a widened viewing angle. The retardation film of the present invention comprises a structural body which simultaneously has form birefringence and molecular-orientation birefringence. Specifically, the retardation film comprises a periodic structure (13) having a unit of at least two layers (11, 12) having different average refractive indices from each other, and at least one of the at least two layers is a layer having optical anisotropy due to molecular-orientation birefringence.
