Abstract:
An organic EL element includes a substrate 20, a lower electrode 21, an upper electrode 26, and an organic layer 22. The organic layer 22 is provided between the upper and lower electrodes 21, 26. The upper and lower electrodes 21, 26 and the organic layer 22 are stacked on the substrate 20. A hole injection layer 23 and a light emitting layer 24 in the organic layer 22 are formed by using an electrospray method, and have a film-like structure in which fine particles are continuously bonded together.
