Abstract

An optoelectronic component may include a first electrode having one outer electrode segment formed at a lateral edge of the first electrode, and one inner electrode segment formed apart from the lateral edge of the first electrode, an electrically conductive current distribution structure formed above the first electrode and having one outer substructure extending over the outer electrode segment, and one inner substructure extending over the inner electrode segment and electrically insulated from the outer substructure, one current lead extending from the lateral edge of the first electrode toward the inner substructure, electrically coupled to the inner substructure, electrically insulated from the outer substructure and which structure corresponds to the current distribution structure, an insulation structure, which covers the current distribution structure and the current lead, an organic functional layer structure, and a second electrode above the organic functional layer structure.
