An organic light emitting diode display includes a substrate having three folded portions overlapping each other, and a first light emitting unit, a second light emitting unit, and a third light emitting unit on respective ones of the three folded portions of the substrate, the first through third light emitting units overlapping each other and emitting different colors, wherein the first through third light emitting units are on a same surface of the substrate, when the substrate is unfolded to have the three folded portions substantially planar.
