A thin film transistor, a method for manufacturing the thin film transistor, and an organic electroluminescence display using the thin film transistor are disclosed. The thin film transistor includes a gate electrode, a semiconductor layer that overlaps the gate electrode, a first insulating layer disposed between the semiconductor layer and the gate electrode, and first and second electrodes that use the semiconductor layer as a channel, and are disposed at different layers. The thin film transistor further includes a second insulating layer disposed between the semiconductor layer and one of the first and second electrodes, and a first doping semiconductor layer disposed between the semiconductor layer and the other of the first and second electrodes.
