An organic light emitting diode display includes: a pixel region; and a peripheral region surrounding the pixel region, the peripheral region including: a gate common voltage line; an interlayer insulating film that covers the gate common voltage line and has a common voltage contact hole exposing part of the gate common voltage line; a data common voltage line that is formed on the interlayer insulating film and comes in contact with the gate common voltage line via the common voltage contact hole; barrier ribs that cover the data common voltage line and have common voltage openings exposing part of the data common voltage line; and a peripheral common electrode that is formed on the barrier ribs and comes in contact with the data common voltage line via the common voltage openings, wherein the barrier ribs are formed at positions corresponding to the boundaries with the common voltage contact hole.
