Abstract

A light emitting component with organic layers, e.g., an organic light-emitting diode, which includes a substrate, at least one light emitting layer, and at least one charge carrier transport layer, having a cathode on the substrate and light emission through the anode. The light emitting component may further include a transport layer that is p-doped with an organic material.
