  • Patent number: 8071999
    Abstract: A flat lighting device includes a layer arrangement, anode and cathode contact regions. The layer arrangement includes an anode layer, a cathode layer, and an organic light-emitting layer arranged between the anode and cathode layers, the layer arrangement having a flat shape which is laterally bounded by an edge region. The anode contact regions contact the anode layer and are implemented along the edge region. The cathode contact regions contact the cathode layer and are implemented along the edge region. The flat shape has a rotational invariance toward rotation by discrete angles. The anode and cathode contact regions may be contacted from one side of the flat shape of the layer arrangement and are arranged to be laterally distributed over the edge region such that the lateral distribution of the anode and cathode contact regions is maintained upon rotation of the layer arrangement by the discrete angles.
