The invention relates to electroluminescent light-emitting devices, characterized in that they contain at least one conductive polymer layer as electrode, thereby preventing an extended use of a transparent oxide or a metal layer. The combination with a doped thin layer made of oligomeres (small-molecules) is particularly advantageous. According to the invention, the construction of organic electroluminescent light-emitting devices is considerably simplified, and the production process can be performed in a more efficient manner. A feature of the invention is the utilization of the high conductivity of the polymer layer and the extraordinary smoothing properties of the combination of polymer/oligomer as functional layer. Due to the high transparency, the layer combination can be used as electrode in an organic light diode or as a separately contactable intermediate electrode in a pile of organic materials. Due to the good interface properties, this functional layer has a considerable advantage over the other formulations with regard to increased efficiency and service life.
