ABSTRACT:
The invention relates to a light-emmiting component having organic layers, in particular to an organic light-emmiting diode. The component has at least one doped charge carrier transport layer (2), a light-emmiting layer (4) and contact layers (1, 5) and also has a blocking layer (3; 3′) wherein an organic material is provided between the charge carrier transport layer (2, 2′) and the light-emmiting layer (4). The energy levels of the charge carried transport layer are chosen in such a way that efficient doping is possible and the blocking layer nevertheless ensures that non-radiating recombination processes on the interface with the emitting layer are prevented.
