1. A liquid crystal display panel, comprising a pixel electrode and a liquid crystal layer on the pixel electrode, wherein the pixel electrode is circular;
wherein the pixel electrode is divided into a plurality of sub-pixel electrodes by a plurality of slits, and the plurality of slits comprise a first slit and a second slit that pass through the center of the pixel electrode and are perpendicular to each other, and a plurality of third slits;
wherein the first slit and the second slit divide the pixel electrode into a first quadrant area, a second quadrant area, a third quadrant area, and a fourth quadrant area that are arranged counterclockwise, and one or more of the third slits are arranged in at least one of the first quadrant area, the second quadrant area, the third quadrant area and the fourth quadrant area,
the plurality of third slits comprises a plurality of fourth slits located in the first quadrant area, the plurality of fourth slits extend in radial directions of the pixel electrode, each of the fourth slits has a first end and a second end, the first end is closer to the first slit and the second slit than the second end, first ends of the fourth slits are communicated with each other, and not communicated with the first slit and the second slit, and at least one fourth slit is located in a direction at an angle having an absolute value of 45 degrees or 135 degrees with respect to a horizontal direction, and
liquid crystal molecules in the liquid crystal layer are, in response to a voltage applied to the pixel electrode, alignable along the radial direction at least in the horizontal direction, a vertical direction, and the direction at the angle having the absolute value of 45 degrees or 135 degrees.
