Tft-lcd array substrate, manufacturing method thereof, and liquid crystal display panel

A thin film transistor liquid crystal display (TFT-LCD) array substrate, comprising:

• a plurality of first gate lines and a plurality of first data lines, and a plurality of pixel regions defined by intersecting of the first gate lines and the first data lines with each other, each of the pixel regions comprising:
• a first pixel electrode and a first thin film transistor (TFT), wherein the first gate line is connected with a first gate electrode of the first TFT, the first TFT is connected with the first pixel electrode to control a display voltage applied on the first pixel electrode, and
• a second TFT and a second pixel electrode, wherein the second TFT is connected with the second pixel electrode to control a common voltage applied on the second pixel electrode,
• wherein the first pixel electrode and the second pixel electrode form the voltage difference to drive liquid crystal molecules, and the first TFT and the second TFT are turned on or off simultaneously.
