When the pixel electrode 20 is energized to obtain a certain voltage, the liquid crystal molecules gradually tilt from the outer side of the pixel electrode 20 to the inner side, the tilting angle is along the extending direction of the strip-shaped branch 23, the tilting directions of the liquid crystal molecules in the four pixel regions are respectively 45 degrees plus and minus and 135 degrees plus and minus, and the tilting directions of the liquid crystal molecules are all directed to the central region of the pixel electrode 20.
