A display includes a switching transistor connected to a scan line and data line, a driving transistor connected to the switching transistor, a storage capacitor between a voltage line and the driving transistor, and an organic light emitting diode connected to the driving transistor. The data line and voltage line are at different layers, and the data line and a gate electrode of the driving transistor are at different layers. Also, a plate of the storage capacitor and the gate electrode of the driving transistor are of a same layer, and semiconductor layers of the switching and driving transistors are of a same layer.
