Abstract

The invention relates to an organic electronic luminescent component with an arrangement of organic layers formed between an electrode and a counter electrode, wherein said arrangement of organic layers is electrically insulated from the electrode and the counter electrode and comprises a light-emitting layer and a charge carrier generation region allocated to the light-emitting layer, wherein the charge carrier generation region is configured to provide positive and negative charge carriers at an application of an electrical AC voltage to the electrode and the counter electrode and wherein a pn-layer transition is formed in the charge carrier generation region by means of a p-doped organic layer and a n-doped organic layer arranged next to the p-doped organic layer.
