Abstract
An organic electro-luminescence device capable of reducing a resistance of a cathode electrode to enhance brightness uniformity at each location within the device is described. The organic electro-luminescence device includes a bank layer formed over a substrate, the bank layer including a first, second, and third portion. A first electrode is formed between the first and second portions of the bank layer. An auxiliary electrode is formed where at least a part of the auxiliary electrode is formed between the second and third portions of the bank layer. A voltage drop prevention pattern is formed on the auxiliary electrode. An organic material layer formed between the first and second portions of the bank layer. A second electrode formed on the organic material layer, where at least a portion of the second electrode is electrically coupled to the auxiliary electrode.
