Abstract: An organic light emitting diode display device which may improve luminous emitting efficiency by forming a scattering layer with a material including fluorine and a method of fabricating the same are discussed. The organic light emitting diode display device can include a thin film transistor formed on a substrate; an overcoat layer formed on the substrate such that the thin film transistor is covered; a scattering layer formed on the overcoat layer and formed with a material including fluorine; and an organic light emitting cell formed on the scattering layer and including a first electrode, an organic emission layer and a second electrode sequentially laminated, wherein light emitted from the organic light emitting cell passes through the scattering layer and then is emitted through the substrate.
