Abstract
To provide a method of efficiently manufacturing an organic light-emitting element with excellent light-emitting characteristics by application, the method includes: preparing ink and filling an inkjet device having an ink ejection nozzle with the ink; preparing a substrate having a base layer including a first electrode; and positioning the inkjet device above the substrate, and causing the inkjet device to eject a drop of the ink onto the base layer, wherein, in the preparation of the ink, a value Z denoting a reciprocal of the Ohnesorge number Oh determined by density ρ (g/m), surface tension γ (mN·m), and viscosity η (mPa·s) of the ink and a diameter r (mm) of the ink ejection nozzle satisfies Formula 1, in the ejection of the drop of the ink, speed V (m/s) of the ejected drop satisfies Formula 2, and the value Z and the speed V (m/s) satisfy Formula 3.
