Abstract: An organic light emitting diode display includes a substrate, a planarization layer disposed on the substrate, a first electrode disposed on the planarization layer, an emission layer disposed on the first electrode, and a second electrode disposed on the emission layer, wherein an uneven pattern is formed on a top surface of the planarization layer, the uneven pattern comprises a strip line having a plurality of thicknesses and widths, and a thickness of the strip line becomes smaller as a distance from a center portion of the first electrode becomes larger.
