Abstract:
1. A method of manufacturing a thin film transistor, comprising: forming a layer structure including a gate electrode, a gate insulation layer and a channel layer; and forming a source line and a drain line to make contact with the channel layer, the source line extending along a direction crossing over the gate electrode and partially overlapping the gate electrode in which both sides of the source line overlapping the gate electrode are entirely positioned between both sides of the gate electrode, and the drain line being spaced apart from the source line by a channel length and having a structure symmetrical to that of the source line, wherein the source line is partially spaced apart from a side of the gate electrode, so that the source line partially surrounds the side of the gate electrode, and the drain line is partially spaced apart from the side of the gate electrode to symmetrically extend with the source line.
