摘要：
A retardation film including: a first optical anisotropic layer including a polymer material; and a second optical anisotropic layer including a liquid crystal material, in which the first optical anisotropic layer has refractive indices which satisfy the following inequation: nz1≧nx1>ny1, the second optical anisotropic layer has refractive indices which satisfy the following inequation: nx2>ny2≧nz2, a fast axis of the first optical anisotropic layer and a slow axis of the second optical anisotropic layer form a predetermined angle such that refractive indices of the retardation film satisfy the following inequation: 0
