    Abstract: Disclosed is a touch organic light-emitting display device that is capable of stably connecting metal mesh electrodes to each other using a plurality of bridges and of minimizing the occurrence of parasitic capacitance. The display device includes an organic light-emitting array including pixel openings and a bank insulation film, and a touch electrode array bonded to the organic light-emitting array. The touch electrode array includes first and second mesh electrodes arranged in first and second directions and having a multiple-lattice structure, bridges for connecting first mesh electrodes to each other, and connecting patterns for connecting second mesh electrodes to each other. The bridges do not overlap the second mesh electrodes but overlap the connecting patterns so as to intersect the same. The first and second mesh electrodes, the bridges and the connecting patterns overlap the bank insulation film.

    Abstract: Disclosed is an organic light-emitting display device that has improved color viewing angle characteristics while including a mesh pattern. The organic light-emitting display device includes an organic light-emitting array including a plurality of pixel openings, and a touch electrode array bonded to the organic light-emitting array. The touch electrode array includes a plurality of first mesh electrodes arranged in a first direction and having a lattice structure, and a plurality of second mesh electrodes arranged in a second direction and having a lattice structure. Each of the first mesh electrodes and the second mesh electrodes includes a plurality of overlapping portions that overlap the pixel openings, and a plurality of non-overlapping portions positioned between the pixel openings. At least some of the overlapping portions include brightness-increasing portions, which are formed of a material different from that of the non-overlapping portions.
