ABSTRACT:
An organic thin film transistor that prevents the surface of an organic semiconductor layer from being damaged and reduces turn-off current, a method of fabricating the same, and an organic light-emitting device incorporating the organic thin film transistor. The organic thin film transistor includes a substrate, source and drain electrodes arranged on the substrate, a semiconductor layer contacting the source and drain electrodes and comprising a channel region, a protective film arranged on the semiconductor layer and having a same pattern as the semiconductor layer, the protective film comprising a laser-absorbing material, a gate insulating film arranged between the gate and the source and drain electrodes, a gate electrode arranged on the gate insulating film and a separation pattern arranged within the semiconductor layer and within the protective film, the separation pattern adapted to define the channel region of the semiconductor layer.
