摘要:
A process of producing a substrate for liquid crystal display device comprising an optically anisotropic layer, which comprises forming the optically anisotropic layer by a process comprising the following [1] to [3]:[1] preparing a substrate having a raw optically anisotropic layer; [2] subjecting the raw optically anisotropic layer to patterned exposures of two or more types having different exposure conditions to each other; [3] subjecting the substrate obtained after the exposure to a heat treatment at 80° C. or higher and 400° C. or lower. By the process, a substrate for liquid crystal display device which contribute to reducing viewing angle dependence of color of a liquid crystal display device can be easily produced.
