Abstract

An organic light-emitting diode includes a carrier; at least two electrodes; an organic layer sequence having at least one active zone that generates light; and light-opaque visual protection layers that have no influence on an emission characteristic of the organic layer sequence and the organic light-emitting diode, one of which is located directly on the carrier, the organic layer sequence is located between the two electrodes and one of the electrodes is attached directly to the carrier, the visual protection layer, viewed in a plan view, completely surrounds the organic layer sequence, at least one of the electrodes is provided with a structuring in a region adjacent to the organic layer sequence in a plan view, in a plan view, the structuring is located completely beside the organic layer sequence, and the structuring is hidden by the visual protection layer for a viewer from outside the organic light-emitting diode.
