Patent ID: 8016629

Claim:
A method of producing an organic electroluminescent device comprising: applying a composition containing an organic electroluminescent compound onto multiple electrodes to form an organic electroluminescent layer on each of the electrodes, wherein a substrate on which the composition is applied is a substrate with one or both of portions between electrodes and a surface of the electrodes having been subjected to water-repellent treatment, the water-repellent treatment forming a water-repellent thin film, wherein around the multiple electrodes on which the water-repellent thin film is formed, an insulating layer is provided having a thickness of 500 nm or less as measured from the substrate surface and having an angle of 0 degrees as observed from the top surface of the electrodes, and the water repellant thin film is formed on the surface of the electrode, on the surface of the insulating layer and, when an opening is present in the insulating layer that exposes the underlying substrate surface, on the substrate surface.
