Abstract

An organic light-emitting diode includes an organic light-emitting layer located between a transparent electrode and one other electrode on a substrate. In some embodiments at least one of the transparent electrode and the other electrode has two layers. The two layers include a structured layer, which is a charge carrier injection layer, and a conductive second layer into which the first layer is embedded. In some embodiments the organic light-emitting layer includes a structured charge carrier blocking layer.
