Abstract:
1. A thin-film transistor, comprising: a gate electrode disposed on a substrate and connected to a gate line; a capacitance compensation structure disposed on the substrate, wherein the capacitance compensation structure is electrically connected to the gate electrode, and the capacitance compensation structure has a first side facing the gate electrode and a second side facing away from the gate electrode; a semiconductor layer disposed on the substrate, wherein the semiconductor layer covers a portion of the gate electrode, and the semiconductor layer at least extends to overlap the first side of the capacitance compensation structure; a dielectric layer disposed on the substrate, wherein the dielectric layer has a first opening and a second opening, and both of the first opening and the second opening expose a portion of the semiconductor layer overlapping the gate electrode respectively; a drain electrode disposed on the substrate and in contact with the semiconductor layer though the first opening; and a source electrode disposed on the substrate and in contact with the semiconductor layer though the second opening.
