Patent ID: 6930331

Claim:
An organic light emitting diode device, comprising: first and second spaced apart substrates facing each other; an array layer formed on the first substrate, the array layer having a plurality of thin film transistors; an organic light emitting diode formed on the second substrate; a plurality of connection patterns disposed between the first and second substrates, the connection pattern connecting respective thin film transistor to the corresponding organic light emitting diode; and a sealant between the first and second substrates to encapsulate the first and second substrates in peripheral portion thereof, 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.
