PROBLEM TO BE SOLVED: To uniform a thickness of an organic EL thin film between effective optical region pixels and in each pixel, in manufacture of an organic EL device forming an organic EL layer by discharging and coating an organic EL material on a substrate by an ink jet system. SOLUTION: In a manufacturing method of the organic electroluminescent device, organic electroluminescent device forming regions related to display containing an effective optical region with a plurality of display pixels arranged, and a first dummy region not related to the display use a substrate for an organic electroluminescent device having a plurality of effective optical region groups. The manufacturing method of an organic EL thin film contains a process forming a second dummy region to surround the plurality of organic electroluminescent device forming regions around a periphery of the effective optical region groups, and a process forming composition containing an organic electroluminescent material in the first dummy region, the second dummy region, and the display pixels.
