Inverse wavelength dispersion retardation film and display device including the same
摘要：
A retardation film including: a first optical anisotropic layer (1) including a polymer material; and a second optical anisotropic layer (2) 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
