Abstract: An organic light emitting diode display device includes a substrate, an organic light emitting diode on the substrate and a capping layer on the organic light emitting diode. The capping layer includes metal iodide selected from alkali metal iodide and alkaline-earth metal iodide. The organic light emitting diode may have reduced driving voltage and improved luminous efficiency.
