Abstract:
1. An organic light-emitting display device, comprising: a substrate; a driving thin film transistor array on the substrate and comprising a semiconductor layer composed of an N-type semiconductor compound, a source electrode connected to a first region of the semiconductor layer, and a drain electrode connected to a second region of the semiconductor layer; at least one insulator on the thin film transistor array; a cathode electrode directly connected to the drain electrode of the driving thin film transistor array; a thin metal film on the cathode electrode and composed of a material having a lower work function than the cathode electrode; an organic light-emitting layer on the thin metal film, the thin metal film being between the organic light-emitting layer and the cathode electrode; and a anode electrode on the organic light-emitting layer, wherein the thin metal film has a thickness ranging from about 0.01 to about 10 Å.
