Abstract
An organic light emitting device and a manufacturing method thereof, including a first signal line and a second signal line intersecting each other on an insulating substrate, a switching thin film transistor connected to the first signal line and the second signal line, a driving thin film transistor connected to the switching thin film transistor, and a light emitting diode ('LD') connected to the driving thin film transistor. The driving thin film transistor includes a driving control electrode and a driving semiconductor overlapping the driving control electrode, crystallized silicon having a doped region and a non-doped region, a driving gate insulating layer disposed between the driving control electrode and the driving semiconductor, and a driving input electrode and a driving output electrode opposite to each other on the driving semiconductor, wherein the interface between the driving gate insulating layer and the driving semiconductor includes nitrogen gas.
