Abstract

In various embodiments, an organic light-emitting organic is provided. The organic light-emitting component may include a first electrode layer, an organic functional layer structure over the first electrode layer, and a second electrode layer over the organic functional layer structure. The second electrode layer and the organic functional layer structure are divided into subregions which are arranged laterally next to one another, which are respectively at least partially separated from one another. A plurality of the subregions are electrically connected to at least two neighboring subregions by at least two corresponding connecting elements with are formed by the second electrode layer and the organic functional layer structure.
