Abstract:
1. A thin film transistor comprising: a substrate; a semiconductor layer on the substrate and comprising source and drain regions, high resistance regions having a smaller width and a longer length than the source and drain regions, a channel region, and connection regions between respective said high resistance regions and the channel region; a gate insulating layer on the semiconductor layer; a gate electrode on the gate insulating layer above the channel region; an interlayer insulating layer on the gate electrode; and source and drain electrodes on the interlayer insulating layer and electrically connected to the source and drain regions, respectively, wherein one of the high resistance regions is between the channel region and the source region, and another one of the high resistance regions is between the channel region and the drain region, and wherein the length of each of the high resistance regions is taken along a path of the high resistance region between the respective connection region and the respective source or drain region.
