Summary:An organic light emitting diode and a method of fabricating the same. The organic light emitting diode includes a substrate, a first electrode on the substrate, emission layers on the first electrode including red, green and blue pixel regions, and a second electrode on the emission layers. The organic light emitting diode further includes an electron transport layer on the emission layers, and an intermediate layer formed by co-depositing metal quinolate and an organic material between at least one of the emission layers and the electron transport layer. The intermediate layer inhibits hole transport and increases a life span of the red pixel region.
