Abstract
A thin film transistor includes a semiconductor pattern on a substrate, a gate insulating film to cover the semiconductor pattern, a gate electrode partially overlapping the semiconductor pattern with the gate insulating film there between, a hole in the gate electrode to expose the gate insulating film, an interlayer insulating film to cover the gate electrode, and a source electrode and a drain electrode contacting the semiconductor pattern through the interlayer insulating layer and the gate insulating layer, wherein the semiconductor pattern includes at least two channels between the source electrode and the drain electrode, the at least two channels having a region with a varying width.
