摘要： An organic light emitting display is disclosed. According to some aspects, the display includes a substrate having a display region and a peripheral region that surrounds the display region. The display further includes a pixel in the display region, and a contact unit in the peripheral region. The contact unit is configured to receive a common power signal from an external power source. A wiring line unit on the substrate provides a driving signal to the pixel. The pixel includes a first electrode provided on the substrate, an organic light emitting layer provided on the first electrode, and a second electrode that protrudes toward the contact unit on a plane to be electrically coupled to the contact unit. As a result, the area in which the second electrode overlaps the wiring line unit in the peripheral region is reduced and the parasitic capacitance that may be generated between the second electrode and the wiring line may be reduced.
