Abstract

An organic optoelectronic component includes an organic functional layer stack between a first electrode and a second electrode including a light-emitting layer formed to emit radiation during operation of the component; a coupling-out layer arranged above the first electrode and/or the second electrode which is in a beam path of the radiation of the light-emitting layer; and a protective layer above the coupling-out layer, wherein the coupling-out layer includes a structured layer and a planarization layer arranged thereabove and the structured layer has a structured surface structured at least in places, the planarization layer planarizes the structured surface of the structured layer, the protective layer cannot be removed without at least partially destroying the coupling-out layer, and adhesion of the structured layer to the planarization layer is smaller than adhesion of the protective layer to the planarization layer.
