An organic light emitting diode display including a substrate, a first electrode disposed on the substrate, a second electrode disposed on the substrate and separated from the first electrode, a pixel defining layer disposed on the first electrode and the second electrode, a first organic emission layer disposed on the first electrode corresponding to the first opening, a second organic emission layer disposed on the second electrode corresponding to the second opening, and a common electrode disposed on the first organic emission layer and the second organic emission layer. The first electrode includes a first dent portion. The second electrode includes a second dent portion having a different size from the first dent portion. The pixel defining layer includes a first opening exposing the first electrode corresponding to the first dent portion and a second opening exposing the second electrode corresponding to the second dent portion.
