Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of a flat and uniform organic EL display element capable of forming a organic layer with corrected patterning error, prevented from the generation of leakage and uneven brightness. SOLUTION: For the manufacturing method of the organic EL display element comprising a positive electrode, a negative electrode and at least one layer of patterned organic layer laid between those electrodes, the organic layer is flattened and a patterning error is corrected after forming the patterned organic layer by coating a solvent capable of dissolving the organic layer on the organic layer by spray coating and redissolving the organic layer.
