An organic light-emitting display apparatus includes a substrate, a plurality of pixel electrodes formed on the substrate, a counter electrode formed to cover all of the plurality of pixel electrodes, organic light emitting layers disposed between the plurality of pixel electrodes and the counter electrode, an encapsulation substrate disposed above the substrate to cover the counter electrode, a sealant formed along edges of the substrate and the encapsulation substrate to seal a space formed between the substrate and the encapsulation substrate, a filler filled in the space formed between the substrate and the encapsulation substrate, and bus electrodes disposed on an inner surface of the encapsulation substrate facing the counter electrode. Each of the bus electrodes includes projecting portions and a base portion connecting the projecting portions to each other. The projecting portions are connected to the counter electrode, and a connection portion of the each of the projecting portions to the counter electrode is disposed between the organic light-emitting layers.
