Abstract: An organic light-emitting device an improved anode structure and an organic electroluminescent display device using the same are provided. The anode structure has a 3 layers stack structure in which a layer closest to an organic light-emissive layer of the organic light-emitting device is made of a material with a high work function such as 5.1 to 5.3 eV. Thus, hole injection efficiency is improved and occurrence of dark spots is suppressed.
