Abstract
An organic light emitting display includes a pixel circuit to supply current to an organic light emitting device. The pixel circuit includes a switching transistor and a driving transistor. The switching transistor includes a first insulating layer between a first gate electrode and an oxide semiconductor layer. The driving transistor includes a second gate electrode on an active layer. The first insulating layer is between the active layer and the second gate electrode.
