Abstract

In at least one embodiment, a light-emitting diode includes a carrier and an organic layer sequence with an active layer. A mirror layer and electrical contact regions are located on a connection side of the carrier. The contact regions are provided for electrically contacting the organic layer sequence. Electrical dummy regions are located on the connection side. The dummy regions are electrically insulated from the contact regions. The mirror layer is present in the dummy regions and in the contact regions. At least two of the dummy regions are arranged in such a way that base areas of these dummy regions cannot be congruently superimposed merely by arbitrary rotation of the carrier relative to a center axis of the carrier perpendicular to the connection side.
