The organic optoelectronic component according to claim 1 , wherein the refractive index of the structured layer and the refractive index of the planarization layer is the same at least in places. 3. The organic optoelectronic component according to claim 1 , wherein the structured layer has structures not visible at least in places for a viewer from outside the organic optoelectronic component. 4. The organic optoelectronic component according to claim 1 , further comprising a protective layer above the coupling-out layer, wherein the protective layer is irreversibly bonded to the planarization layer. 5. The organic optoelectronic component according to claim 1 , wherein adhesion of the structured layer to the planarization layer is smaller than the adhesion of the protective layer to the planarization layer. 6. The organic optoelectronic component according to claim 1 , wherein the structured layer has structures sized in the range of 1 nm to 100 m. 7. The organic optoelectronic component according to claim 1 , wherein the structuring is periodic or non-periodic. 8.
