Abstract: A display device that is capable of being manufactured through a simplified process and at reduced cost is disclosed. The display device is configured such that a plurality of grouped cathode electrodes and a plurality of grouped black matrices intersect each other in the state in which an encapsulation unit is disposed therebetween in order to form a touch sensor, so that a process of forming first and second touch electrodes is omitted and a separate adhesion process becomes unnecessary, whereby structural simplification is achieved while costs are reduced.

Abstract: An organic light-emitting display device characterized by improved reliability is disclosed. The organic light-emitting display device is configured such that each of an organic encapsulation layer, which is disposed on a light-emitting element, and an upper inorganic encapsulation layer, which is disposed on the organic encapsulation layer, are divided into a plurality of parts. Even when cracks are formed in a subpixel due to an external impact or when external moisture or oxygen permeates into the subpixel, therefore, it is possible to prevent the cracks, the moisture, or the oxygen from diffusing to an adjacent subpixel, whereby the reliability and lifespan of the display device are improved.

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.
