Patent ID: 7550766

Claim:
A Thin Film Transistor (TFT), comprising: a substrate; a gate electrode arranged on the substrate; a source electrode and a drain electrode separated from each other and insulated from the gate electrode; and a semiconductor layer insulated from the gate electrode, contacts each of the source and drain electrodes, and includes grooves that separate at least a region of the semiconductor layer between the source and drain electrodes from an adjacent TFT; wherein each groove passes at least a portion of the semiconductor layer corresponding to the source and drain electrodes, and covers the source and drain electrodes except for a portion of the source electrode that faces the drain electrode and a portion of the drain electrode that faces the source electrode, wherein a portion of the semiconductor layer is arranged in an area that does not correspond to the source and drain electrodes, said portion of the semiconductor layer also not being arranged between the source and drain electrodes.
