An optically anisotropic layer comprising a polymer and a specific compound 1, wherein when the polymer is formed into a film of the polymer by a coating method using a solution of the polymer, the in-plane direction of the film is maximized. The refractive index nx (P) in the direction of the refractive index, the refractive index ny (P) in the aforementioned in-plane direction of the film and a direction perpendicular to the direction of the aforementioned nx (P), and the refractive index nz ( P) Satisfy nz (P)> nx (P) ≧ ny (P). The Rth (A450), Rth (A550), and Rth (A650) of the optically anisotropic layer have a specific relationship. |
