Abstract
A light-emitting diode matrix comprises a substrate, first and second electrodes electrically insulated from each other formed in or on the substrate, and a first organic layer on the first electrode and a second organic layer on the second electrode. The first organic layer is separated from the second organic layer by separator means. Further, the light-emitting diode matrix comprises a cap electrode with an area disposed on the first organic layer and an area disposed on the second organic layer. The areas of the cap electrode are connected in an electrically conductive way via an area of the cap electrode disposed on the separator means.

A light-emitting diode matrix, comprising:
- a substrate;
- first and second electrodes electrically insulated from each other, formed in or on the substrate;
- a first organic layer on the first electrode and a second organic layer on the second electrode;
- a separator separating the first organic layer from the second organic layer, wherein the separator is implemented in form of a recess in the substrate, and wherein a separator sidewall of the recess facing the first organic layer has a first disruption edge, and wherein a separator sidewall of the recess facing the second organic layer has a second disruption edge, wherein the disruption edges are realized in that the separators have an undercut;
- a cap electrode with an area disposed on the first organic layer and an area disposed on the second organic layer, which are connected in an electrically conductive way via an area of the cap electrode disposed on the separator.
