Abstract: An organic light emitting diode display includes an emission control connector between a driving transistor and an organic light emitting diode of a pixel. The emission control connector connects the driving transistor and the organic light emitting diode and overlaps a portion of a repair line. A first shorting assistance member overlaps the repair line and the emission control connector, and serves to induce a chain reaction to allow a short to form between the repair line and the emission control connector when a low-energy laser beam is applied.
