A thin film transistor liquid crystal display (TFT-LCD) array substrate and a method of manufacturing a TFT-LCD array substrate are provided in the invention. The TFT-LCD array substrate comprises a plurality of gate lines and a plurality of data lines formed on a substrate. A plurality of pixel regions are defined by the gate lines and the data lines. A pixel electrode, a first thin film transistor for controlling the charge of the pixel electrode and a second thin film transistor for controlling the pre-charge of the pixel electrode are formed in each pixel region.
