An organic light emitting display apparatus includes a plurality of first electrodes disposed in each of a plurality of pixels on a substrate, a plurality of lower auxiliary electrodes insulated from the first electrodes and in which the lower auxiliary electrodes are disposed in a first direction, an organic layer disposed on the first electrodes, and a second electrode facing the first electrodes and covering the organic layer. The second electrode is disposed on substantially an entire surface of the substrate. The organic light emitting display apparatus further includes a plurality of upper auxiliary electrodes disposed on the second electrode in a second direction.
