An organic light emitting diode display comprises a substrate having a pixel area and a non-pixel area, a plurality of pixels formed in the pixel area, a power line with a uniform width formed in the non-pixel area configured to supply a common power voltage to the pixels, a cathode electrode formed on the substrate, and a cathode power line formed in the non-pixel area on the same layer as the power line and coupled to the cathode electrode to supply a cathode voltage to the pixels, wherein each pixel comprises a thin film transistor and an organic light emitting element.
