Abstract
A thin film transistor (TFT) includes a scan line on a substrate, the scan line including a straight portion extending along a first direction, an active layer including an oxide semiconductor and overlapping the straight portion of the scan line, the active layer having a first region, a second region, and a third region that are linearly and sequentially aligned along the first direction, a first insulating layer between the active layer and the scan line, a first electrode connected to the first region of the active layer, and a second electrode connected to the third region of the active layer.

-16. (canceled)
A thin film transistor (TFT), comprising:
- a scan line;
- an active layer including an oxide semiconductor, the active layer having a first region, a second region, and a third region that are linearly and sequentially aligned along a first direction, the second region being disposed between the first region and the third region;
- an insulating layer between the active layer and the scan line;
- a first electrode having a first contact portion contacted with the first region of the active layer;
- and
- a second electrode having a second contact portion contacted with the third region of the active layer,
- wherein the first contact portion and the second contact portion overlap with the scan line.
A flat display device, comprising:
- a thin film transistor (TFT), the TFT including:
- a scan line,
- an active layer including an oxide semiconductor, the active layer having a first region, a second region, and a third region that are linearly and sequentially aligned along a first direction, the second region being between the first region and the third region,
- an insulating layer between the active layer and the scan line,
- a first electrode having a first contact portion contacted with the first region of the active layer, and
- a second electrode having a second contact portion contacted with the third region of the active layer;
- a first capacitor electrode on a substrate;
- a second capacitor electrode connected to the second electrode of the TFT, the second capacitor electrode being insulated from the first capacitor electrode;
- and
- a pixel electrode connected to the second electrode of the TFT and to the second capacitor electrode,
- wherein the first contact portion and the second contact portion overlap with the scan line.
