A TFT-LCD array substrate, a manufacturing method thereof and a liquid crystal display panel are provided in the invention. The TFT-LCD array substrate comprises a plurality of first gate lines and a plurality of first data lines, and a plurality of pixel regions are defined by intersecting the first gate lines and the first data lines with each other. A first pixel electrode and a first TFT are formed in each of the pixel regions, and a second TFT and a second pixel electrode are further comprised in each of the pixel regions. The second TFT is connected with the second pixel electrode, the first pixel electrode and the second pixel electrode form the voltage difference to drive the reversion of the liquid crystal molecules, and the first TFT and the second TFT are turned on or off simultaneously.
