ABSTRACT:
An organic light emitting diode device includes an array layer having a plurality of thin film transistors, an organic light emitting diode formed on a second substrate, a plurality of connection patterns disposed between the first and second substrates, the connection pattern connecting a respective thin film transistor to the corresponding organic light emitting diode and a sealant between the first and second substrates, wherein each thin film transistor includes: a gate electrode on the first substrate, the gate electrode having an opening in the middle thereof; a gate insulating layer over the gate electrode; a semiconductor layer on the gate insulating layer above the gate electrode; a drain electrode on the semiconductor layer corresponding to the opening of the gate electrode; and first and second source electrodes formed respectively on both sides of the semiconductor layer and spaced apart from the drain electrode.
