Array substrate and fabrication method thereof, and liquid crystal display device

摘要

Embodiments of the invention provide an array substrate and a fabrication method thereof, and a liquid crystal display device. The array substrate comprises: a gate line, a data line, and a pixel unit formed by the gate line and the data line intersecting with each other. A first thin-film transistor and a pixel electrode are formed in the pixel unit, and the pixel electrode has slits. The pixel unit further comprises a second thin-film transistor, a first common electrode and a second common electrode, and the second thin-film transistor is configured to turn on and transmit a signal of the first common electrode to the second common electrode when a data line signal is at a high level.
