Abstract:
1. A thin film transistor array substrate, comprising a thin film transistor as a switch device of a pixel unit on a substrate, the thin film transistor comprising a source electrode that is connected to a pixel electrode and that extends over a gate line, a drain electrode that is connected to a data line and having a U-type shape, and a channel region between the source electrode and the drain electrode, and further comprising a source extension region formed on the source electrode and connected to the pixel electrode through the source electrode, wherein the source extension region extends perpendicular to and crosses over the source electrode to form a cross-type shape, and a drain extension region formed at both ends of the U-type shaped drain electrode and extending outwards therefrom; the source extension region being disposed opposite to the drain extension region to form a channel extension region therebetween, and the source extension region and the drain extension region extending over the gate line in a direction parallel to an extension direction of the gate line on the substrate.
