ABSTRACT:
A tandem OLED device including an anode; a cathode; at least two electroluminescent units disposed between the anode and the cathode, wherein each of the electroluminescent units includes at least one hole-transporting layer and one organic light-emitting layer; and an intermediate connector of at least two layers disposed between adjacent electroluminescent units, wherein the intermediate connector includes an organic alkali metal complex layer and an organic electron-accepting layer, the organic electron-accepting layer being disposed closer to the cathode than the organic alkali metal complex layer, and there is present metallic aluminum in the organic alkali metal complex layer.
