Abstract
A thin-film transistor substrate includes: a substrate; a semiconductor layer on the substrate, where the semiconductor layer includes a first conductive region, a second conductive region, and a first channel region between the first conductive region and the second conductive region; a gate insulating layer on the semiconductor layer, where the gate insulating layer includes a first charge implanted region which overlaps a portion of the first channel region and into which charged ions are implanted; and a first gate electrode on the gate insulating layer to overlap the first channel region. The first charge implanted region is shifted to the first conductive region or the second conductive region.
