PROBLEM TO BE SOLVED: To provide a method of producing a patterned birefringent product using a cholesteric structure efficiently in orientation and patterning processes. SOLUTION: The method of producing a patterned birefringent product, comprises at least the following steps [1] to [3] in this order: [1] producing a birefringent pattern building material having at least one optically anisotropic layer, including coating and drying a composition containing at least one rod-like liquid crystalline compound having at least two reactive groups and at least one chiral agent to form a cholesteric liquid crystal phase, and then subjecting the cholesteric liquid crystal phase to heating or exposure to radiation to form the optically anisotropic layer containing a polymer fixed by polymerization and fixing; [2] subjecting the birefringent pattern building material to a patterned exposure; and [3] baking a laminate obtained after the step [2] at 50 to 400°C.
