ABSTRACT:
An organic light-emitting diode for a display and a method for fabricating the organic light-emitting diode which has lower contact resistance between the cathode and the cathode contact layer and which may be operated with a reduced amount of power. The organic light-emitting diode has an anode layer, an emissive layer, a cathode which has an electron injecting layer and an electrical conducting layer, and a cathode contact layer which electrically connects the cathode and an electrical driving system of the display. The electrical conducting layer of the cathode is electrically connected with the cathode contact layer, however, the electron injecting layer is not in direct contact with the cathode contact layer. Both the electron injecting layer and the electrical conducting layer of the cathode may be formed such that they are aligned with the emissive layer. In this case, a connecting layer is formed to connect the electrically conducting layer and the cathode contact layer.
