An organic light emitting display includes a driving transistor, an organic light emitting diode, an interlayer insulating layer, and a connection electrode. The interlayer insulating layer covers the driving transistor, and first and second via holes are formed in the interlayer insulating layer. The organic light emitting diode is on the interlayer insulating layer and connected to the driving transistor. The connection electrode is on the interlayer insulating layer and connected to an auxiliary line through the second via hole. The connection electrode surrounds a portion of the interlayer insulating layer together with the auxiliary line. The organic light emitting diode includes an anode connected to the driving transistor through the first via hole, an organic light emitting layer on the anode, and a cathode on the organic light emitting layer and connected to the auxiliary line through the connection electrode.
