Abstract:
1. A thin-film-transistor array substrate, characterized in that: the thin-film-transistor array substrate comprises: a substrate; a scan-signal line mounted on the substrate along a horizontal direction and having a first side and a second side opposite to the first side; a data-signal line mounted on the substrate along a vertical direction and isolatedly crossed with the scan-signal line; a thin-film transistor formed closed to a junction of the scan-signal line and the data-signal line and having a gate electrode, a semiconductor layer, a drain electrode and a source electrode, wherein the gate electrode is a portion of the scan-signal line and has an opening, the opening is disposed in a center of the gate electrode and extends to the first side of the scan-signal line; the semiconductor layer is isolatedly mounted on the gate electrode; the drain electrode is mounted on the semiconductor layer and corresponds to the opening of the gate electrode in position; the source electrode extends from a side of the data-signal line and surrounds the drain electrode and the opening of the gate electrode along an edge of the semiconductor layer; and a compensation electrode integrally extending from the second side of the scan-signal line and corresponding to the gate electrode; wherein, an area of the compensation electrode is equal to an area of the opening of the gate electrode, and a distance between the compensation electrode and the data-signal line is more than 3.5 micrometers.
