Abstract

A thin film transistor including: an active layer on a substrate, the active layer having at least two unit channels; and source and drain electrodes on the active layer, wherein an interval D between each of the channels is larger than a unit channel width W.

Claims (11)

1. A method for fabricating a liquid crystal display device comprising:

forming a liquid crystal display panel; and

forming a liquid crystal driving device including first and second multi-channel thin film transistors respectively having an interval D between unit channels, a unit channel width W, and a unit channel length L,

wherein a W/L ratio of the first multi-channel thin film transistor is larger than a W/L ratio of the second multi-channel thin film transistor and the interval between the unit channels of the first multi-channel thin film transistor is larger than the interval between the unit channels of the second multi-channel thin film transistor.

2. The method of claim 1 , wherein forming a liquid crystal display panel includes:

forming an active layer on a substrate, the active layer having at least two unit channels; and

forming source and drain electrodes on the active layer.

3. The method of claim 1 , wherein 0.5 μm≦W≦1000 μm and 0.5 μm≦D≦500 μm.

4. The method of claim 1 , wherein 0.5 μm≦W≦500 μm and 0.5 μm≦D≦250 μm.

5. The method of claim 1 , wherein 0.25 μm≦W≦500 μm and 1 μm≦D≦1000 μm.

6. The method of claim 1 , wherein the number of the unit channel of the first multi-channel thin film transistor is more than the number of the unit channel of the second multi-channel thin film transistor.
