| 摘要 |
The invention provides 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 the substrate on which the composition is applied is a substrate with the portions between electrodes and/or the surface of the electrodes having been subjected to water-repellent treatment. By using this method, deterioration of a device and reduction in performance due to existence of an insulating layer which is indispensable for segregation of each polymer light-emitting compound in conventional process of applying polymer light-emitting compounds can be avoided.
