Abstract

An optoelectronic component is provided with a carrier; a zinc oxide layer arranged on the carrier and having the first and second regions, wherein the first region is a first electrode structure which is doped with aluminum so that the first region is transparent and electrically conductive; an organic optically functional layer structure arranged at least partially over the first electrode structure; and a second electrode structure arranged at least partially over the organic optically functional layer structure. The first and second electrode structures electrically contact the organic optically functional layer structure. The zinc oxide layer has a lower doping in the second region than the first electrode structure. The zinc oxide layer is configured in the second region as a varistor layer structure, which is arranged between the first and second electrode structures and contacts the two electrode structures. The varistor layer structure adjoins the optically transparent first region.
