PROBLEM TO BE SOLVED: To provide an anisotropic optical film having a small phase difference and less depolarization (light leakage) when improved in anisotropy when used in various display devices. SOLUTION: The film has at least a low refractive index region and a high refractive index region, and the low refractive index region and the high refractive index region are alternately arranged on the film surface. An anisotropic optical film having a structure in which a refractive index region and a high refractive index region extend in the thickness direction, and at least cures a monomer, oligomer, prepolymer or macromonomer of a photocurable compound having a silicone skeleton. An anisotropic optical film having an in-plane retardation of 25 nm or less. [Selection] Figure 1 |
