Abstract
An organic light-emitting device and a method for producing an organic light emitting device are disclosed. In an embodiment the device includes a substrate and at least one layer sequence arranged on the substrate and suitable for generating electromagnetic radiation. The at least one layer sequence includes at least one first electrode surface arranged on the substrate, at least one second electrode surface arranged on the first electrode surface and an organic functional layer stack having organic functional layers between the first electrode surface and the second electrode surface. The organic functional layer stack includes at least one organic light-emitting layer, wherein the at least one organic light-emitting layer is configured to emit light, wherein the organic functional layer stack includes at least one inhomogeneity layer, and wherein a thickness of the at least one inhomogeneity layer varies in a lateral direction.
