Abstract

The invention relates to an electroluminescent light-emitting device comprising an arrangement of organic layers which are applied to a substrate, and also to a method for its production. The arrangement of organic layers comprises the following layers: at least one charge carrier transport layer consisting of organic material, and at least one light-emitting layer consisting of organic material. The arrangement of organic layers furthermore comprises at least one doped fullerene layer which has a doping that increases the electrical conductivity.
