Zusammenfassung: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.
