Display substrate, display panel and display device

A display substrate, comprising:

• a base substrate;
• a plurality of pixel units arranged in an array on the base substrate;
• data lines located between any two adjacent columns of pixel units;
• and
• a group of gate lines arranged corresponding to respective rows of pixel units;
• wherein each gate line segments a pixel region of each pixel unit in a corresponding row of pixel units into a first sub-pixel region and a second sub-pixel region;
• each pixel unit comprises slit electrodes, and two thin film transistors arranged corresponding respectively to the first sub-pixel region and the second sub-pixel region;
• wherein the slit electrodes comprise a first slit electrode and a second slit electrode corresponding respectively to the first sub-pixel region and the second sub-pixel region, wherein:
• each of the first slit electrode and the second slit electrode comprises at least one slit group, each slit group comprises a plurality of slits arranged in a same direction, an extension direction of each slit in one of the at least one slit group of the first slit electrode is different from an extension direction of each slit in at least one of the at least one slit group of the second slit electrode, and a direction of a corresponding electric field formed by the one of the at least one slit group of the first slit electrode is different from a direction of a corresponding electric field formed by the at least one of the at least one slit group of the second slit electrode.
