Abstract
A method for producing an organic electroluminescent panel having an organic layer formed by a coating step and a large aperture ratio includes: a first step of arraying and distributing a plurality of first electrodes on or above a substrate; a second step of forming stacking bodies each composed of a plurality of organic-emitting layer on the top face of each of the first electrodes; and a third step of forming organic electroluminescent elements by forming second electrodes respectively on or above the stacking bodies. In the first step, a conductive body having an angled edge portion forming a edge line surrounding the top face itself is used. The second step includes a step of supplying at least a liquid having a light-emitting organic material that is ejected from a nozzle and supplied in a fine flow shape to the organic layer on the top face.
