An organic light-emitting display device, which may be configured to prevent moisture or oxygen from penetrating the organic light-emitting display device from the outside is disclosed. An organic light-emitting display device, which is easily applied to a large display device and/or may be easily mass produced is further disclosed. An organic light-emitting display device may include, for example, a thin-film transistor (TFT) including a gate electrode, an active layer insulated from the gate electrode, source and drain electrodes insulated from the gate electrode and contacting the active layer and an insulating layer disposed between the source and drain electrodes and the active layer; and an organic light-emitting diode electrically connected to the TFT. The insulating layer may include, for example, a first insulating layer contacting the active layer; and a second insulating layer formed of a metal oxide and disposed on the first insulating layer.

Organic light-emitting display device

A thin film transistor (TFT) using an oxide semiconductor as an active layer, a method of manufacturing the TFT, and a flat panel display device having the TFT include a gate electrode formed on a substrate; an active layer made of an oxide semiconductor and insulated from the gate electrode by a gate insulating layer; source and drain electrodes coupled to the active layer; and an interfacial stability layer formed on one or both surfaces of the active layer. In the TFT, the interfacial stability layer is formed of an oxide having a band gap of 3.0 to 8.0 eV. Since the interfacial stability layer has the same characteristic as a gate insulating layer and a passivation layer, chemically high interface stability is maintained. Since the interfacial stability layer has a band gap equal to or greater than that of the active layer, charge trapping is physically prevented.
