Abstract
Provided is a method capable of producing an optically anisotropic laminated body in which defects are hardly generated so that light leakage is scarcely caused. This method is a method for producing an optically anisotropic laminated body including a substrate, an oriented film, and an optically anisotropic film, and has steps of: applying, to a surface of the substrate, an oriented-film-forming composition including an oriented-film-forming material and a solvent and having a viscosity of 4 mPa·s or less at 25° C., and drying the resultant to form the oriented film; and then applying, onto the resultant oriented film, an optically-anisotropic-layer-forming composition including a polymerizable liquid crystal compound, and drying the resultant to orient the polymerizable liquid crystal compound vertically to the surface of the substrate to form the optically anisotropic film.
