Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a cholesteric liquid crystal color filter capable of manufacturing a multi-colored filter having high quality while reducing material loss. SOLUTION: After a cholesteric liquid crystal layer 16 provided on a temporary substrate 10 is laminated on a substrate 22, the cholesteric liquid crystal layer 16 is heated up to a prescribed temperature and exposed to an active light beam using a pattern at this temperature to form a first pattern. (stage G.) Then the cholesteric liquid crystal layer 16 is heated up to a temperature different from the temperature at the time of forming the first pattern and exposed to the active light beam at this temperature using a pattern different from the pattern at the time of forming the first pattern to form a second pattern. Then, a third pattern is formed if it is needed.
