Abstract:
1. An organic electroluminescent device comprising a substrate, a substrate electrode on top of the substrate, an electroluminescent layer stack with at least one organic light emitting layer on top of the substrate electrode, a counter electrode at least covering the electroluminescent layer stack, and a short prevention layer covering the counter electrode establishing a double layer (DL) of counter electrode and short prevention layer, and an electrically isolating layer at least partly on top of the short prevention layer, where a tensile stress (TS) is induced in the double layer (DL) by the short prevention layer, which is suitable to roll-up the double layer (DL) after deposition of the electrically isolating layer adjacent to a cut introduced at least to the double layer (DL) in an area, where the double layer (DL) is arranged on top of the electroluminescent layer stack suitable to electrically disconnect the counter electrode from the substrate electrode, where the electrically isolating layer at least partly covers the area of the double layer with the introduced cut to partly dissolve the electroluminescent layer stack at the cut weakening the adhesion of the double layer to the electroluminescent layer stack adjacent to the cut to roll-up the double layer in the vicinity of the cut.
