PROBLEM TO BE SOLVED: To provide an organic electroluminescent element capable of uniform light emission by improving wetting-up to barrier ribs 3, in a manufacturing method of an organic electroluminescent element having at least first electrodes 2 and pixel barrier ribs 3 on a substrate 1, hole transport layers 4 and organic luminescent layers 5 between the pixel barrier ribs 3, and a second electrode 6 on upper parts thereof. SOLUTION: This manufacturing method is characterized by including a process of forming the hole transport layers 4 by applying a coating liquid containing a hole transport material between the pixel barrier ribs 3 formed on the substrate 1, thereafter arranging a solution used as a solvent of the hole transport material on the surfaces of the hole transport layers 4, furthering leveling, and thereafter drying it.
