An organic light emitting diode display includes: a substrate including a display area and a non-display area adjacent to the display area; a pixel thin film transistor positioned in the display area of the substrate; a first data wire positioned on the pixel thin film transistor; a second data wire positioned on the first data wire; an organic light emitting element positioned on the second data wire and electrically connected to the pixel thin film transistor through the first data wire and the second data wire; a circuit unit positioned in the non-display area of the substrate and including a circuit thin film transistor electrically connected to the pixel thin film transistor; and a common power supply line overlapping at least part of the circuit unit, electrically connected to the organic light emitting element, and formed on a same layer as the second data wire.
