Display substrate and display device

A display substrate, comprising:

• a base substrate;
• a plurality of pixel units, arranged in an array on the base substrate along a first direction and a second direction;
• and
• a plurality of data lines, arranged along the first direction, and each of the data lines extends along the second direction,
• wherein each of the pixel units is located between two of the data lines adjacent to each other, each of the pixel units comprises a gate structure extending along the first direction, a first display region located on a first side of the gate structure, and a second display region located on a second side of the gate structure;
• the first display region comprises at least two domains spaced apart in the first direction and a first space between the at least two domains and extending along the second direction, the second display region comprises at least two domains spaced apart in the first direction and a second space located between the at least two domains of the second display region and extending along the second direction;
• and
• each of the pixel units further comprises a discharge line and a common electrode strip, the discharge line comprises a first conductive part and a second conductive part, the first conductive part extends along the second direction and is located at the first space, the second conductive part extends along the second direction and is located at the second space, the common electrode strip is located at an edge of the first display region adjacent to the data lines, and no common electrode strip is arranged on an edge of the second display region adjacent to the data lines;
• each of the pixel units further comprises:
• a vertical common electrode line,
• wherein an orthographic projection of the vertical common electrode line on the base substrate is overlapped with both an orthographic projection of the first conductive part on the base substrate and an orthographic projection of the second conductive part on the base substrate.
