Abstract
Official abstract text for this publication.
The present invention relates to a method for producing an organic light emitting device, comprising a step of sequentially forming on a substrate a first electrode formed of a metal, one or more organic material layers including a light emitting layer, and a second electrode, which comprises a step of forming a layer on the first electrode using a metal having the higher oxidation rate than the first electrode before forming the organic material layer, and to an organic light emitting device produced by the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method to reduce or remove a native oxide on a cathode in an organic light emitting device, comprising: forming on a substrate the cathode, the cathode comprising a first metal and the native oxide layer of the first metal, forming a layer comprising a second metal directly in contact with the native oxide, by a vacuum thermal evaporation, on the native oxide layer of the first metal and introducing oxygen plasma, such that the second metal and the…
