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 a radiation during operation of the component, and 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, 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, and a difference in the refractive indices of the structured layer and the planarization layer is smaller than 0.3 at least in places.
