The present disclosure relates to an organic light emitting diode display having a quantum dot. The present disclosure suggests an organic light emitting diode display including a substrate having a plurality of pixel area, each pixel area having a light emitting area and a non-light emitting area; a thin film transistor disposed in the non-light emitting area; an organic light emitting diode including an anode electrode, a cathode electrode and a source energy layer between the anode electrode and the cathode electrode, connected to the thin film transistor, and disposed in the light emitting area; an encapsulation layer joined on the substrate; and a quantum light emitting layer radiating lights having any one wavelength by an energy from the source energy layer, and disposed on an inner surface of the encapsulation layer as corresponding to the source energy layer.
