Abstract: A light emitting component is disclosed. In an embodiment a light-emitting device includes at least one active layer stack configured to generate light, a first electrode electrically contacting the at least one active layer stack, a second electrode electrically contacting the at least one active layer stack and at least one light-emitting face for emitting light. The device further includes a first contact structure electrically conductively connected to the first electrode and a second contact structure electrically conductively connected to the second electrode, wherein the first contact structure laterally surrounds a major part of the at least one light-emitting face and a major part of the second contact structure, and wherein the second contact structure laterally surrounds a major part of the at least one light-emitting face.

Abstract: A method for producing an organic light-emitting component is disclosed with providing a carrier, forming a first electrode over the carrier, forming an organic functional layer structure over the first electrode, and forming a second electrode over the functional layer structure. The first and second electrodes and the functional layer structure overlap in an optically active region which extends in the lateral direction and is embodied to generate light. In an optically inactive region extending over the carrier in the lateral direction, an electrically conductive contact layer is formed over the carrier, so that it is in direct physical and electrical contact with the first electrode and/or the second electrode. A first contact section and at least one second contact section of the layer are separated from one another by a lithographic process, so that they are electrically insulated from one another. The layer is structured by a laser beam.
