Abstract
An organic lighting emitting diode display device (OLED display device) and a method of fabricating the same. The OLED display device includes: a substrate; a first electrode disposed on the substrate; an emission layer disposed on the first electrode; a second electrode disposed on the emission layer; and a hole injection layer disposed between the first electrode and the emission layer or between the emission layer and the second electrode, and formed of an inorganic semiconductor material, which evaporates at a temperature of 1100° C. or less. The method includes forming the hole injection layer between the first electrode and the second electrode, by thermally evaporating the inorganic semiconductor material, at a temperature of 1100° C., or less.
