PROBLEM TO BE SOLVED: To provide an organic light emission device manufacturing method that can manufacture a device having excellent light emission characteristics by forming a high-quality organic layer, and an ink coating device.SOLUTION: An organic layer in an organic light emission device is formed by using a circulation type ink coating device 5. In the formation of the organic layer, measurement data on ink flow rates per unit time is continuously transmitted from flow rate measuring units 557, 567, 577, 587 to a controller 541 of the device. The controller 541 receiving this data estimates the viscosity of each ink, and sets a voltage value corresponding to each ink viscosity from a reference table stored in a memory 544. These set voltage values are transmitted to voltage controllers 545 to 548. The voltage controllers 545 to 548 apply a voltage to piezoelectric elements 5005, 5105, 5205, 5305, respectively, on the basis of the received set voltage values. |
