Provided is an optically anisotropic film which exhibits a feature of improving a viewing angle in a liquid crystal liquid crystal display device and can be manufactured at low cost. When the refractive index in the in-plane slow axis direction is nx, the refractive index in the fast axis direction in the film plane is ny, and the refractive index in the film thickness direction is nz, Δn h = nx−ny. ≦ 3.0 × 10 −4 and Δn v = (nx + ny) /2−nz≧3.0×10 −3 , and the photoelastic coefficient is 5 × 10 −12 m 2 / N or more and 20 × 10 −. An optically anisotropic film having a thickness of 12 m 2 / N or less. [Selection diagram] None |
