Display substrate and display panel

A display substrate, comprising:

• a base substrate;
• and a plurality of gate lines, a plurality of data lines and a plurality of sub-pixels on the base substrate, wherein
• the plurality of sub-pixels form a plurality of first pixel groups arranged side by side along a first direction and a plurality of second pixel groups arranged side by side along a second direction;
• each of the plurality of first pixel groups comprises sub-pixels arranged side by side in the second direction;
• each of the plurality of second pixel groups comprises sub-pixels arranged side by side in the first direction;
• gate lines are provided on each of two sides of each second pixel group in the second direction;
• one of two adjacent sub-pixels in the second pixel group is coupled to a gate line located on one of two sides of the second pixel group in the second direction, and the other of the two adjacent sub-pixels is coupled to a gate line located on the other of the two sides of the second pixel group in the second direction;
• wherein any two adjacent first pixel groups define a first region therebetween, any two adjacent second pixel groups define a second region therebetween, and the display substrate further comprises a common electrode line in at least a portion of the first regions, and the common electrode line and the data line are located in different first regions;
• and
• the common electrode line comprises a plurality of common electrode line segments and protrusions each coupled between two common electrode line segments, a width of at least one of the protrusions in the first direction is larger than a width of the common electrode line segment in the first direction;
• and the protrusions are located in the second region, and the two common electrode line segments coupled to a corresponding protrusion extend along two straight lines that are not intersecting with each other.
