An organic light emitting display including a semiconductor layer formed on a substrate, a first insulating layer formed on the substrate and including a contact hole, an electrode formed on the first insulating layer and coupled to the semiconductor layer through the contact hole, a second insulating layer formed on the first insulating layer and including a via hole, and a pixel electrode formed on the second insulating layer and coupled to the electrode through the via hole. The via hole is formed corresponding to the contact hole, and the via hole has a larger size than the contact hole.
