Abstract
An organic light emitting diode display includes a first thin film transistor of which a channel is formed in a polycrystalline transistor, a second thin film transistor of which a channel is formed in an oxide semiconductor layer, an organic light emitting diode electrically connected to the first thin film transistor, a storage capacitor having a first electrode and a second electrode, wherein the second electrode of the storage capacitor is electrically connected to a gate electrode of the first thin film transistor, and an overlapping layer overlapping the oxide semiconductor layer in a plan view and receiving a positive voltage. The oxide semiconductor layer is positioned higher than the gate electrode of the first thin film transistor and the second electrode of the storage capacitor.
