Patent ID: 7999290

Claim:
An organic electroluminescent device, comprising: first and second substrates facing each other and spaced apart from each other; a gate line on an inner surface of the first substrate; a data line and a power line crossing the gate line and spaced apart from each other; a switching thin film transistor connected to the gate line and the data line; a driving thin film transistor connected to the switching thin film transistor and the power line, the driving thin film transistor having a channel region including at least two-half ring shapes, wherein the at least two-half ring shapes each having a “U” shape are disposed adjacent to each other to constitute a “W” shape; an electric connection pattern connected to the driving thin film transistor, the connection pattern being disposed over the driving thin film transistor; and an organic electroluminescent diode on an inner surface of the second substrate, the organic electroluminescent diode being connected to the electric connection pattern.
