Abstract:
1. An organic electroluminescent device comprising an electroluminescent layer stack on top of a substrate, where the electroluminescent layer stack comprises an organic light-emitting layer stack with one or more organic layers sandwiched between a first electrode facing towards the substrate and a second electrode, where the second electrode comprises a layer stack of at least a transparent conductive protection layer on top of the organic light-emitting layer stack, a transparent organic conductive buckling layer disposed on top of the transparent conductive protection layer, the transparent organic conductive buckling layer having a glass transition temperature lower than the lowest glass transition temperature of the organic layers within the organic light-emitting layer stack, and a reflective stress inducing layer on top of the buckling layer to introduce stress to the buckling layer.
