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.
