Abstract
The present application provides a display substrate and a display device. In the display substrate, a plurality of sub-pixel driving circuits are divided into a plurality of sub-pixel driving circuit column; a plurality of data lines are divided into a plurality of data line groups, and each data line group comprises two adjacent data lines; one data line in the data line group is separately coupled with odd-numbered sub-pixel driving circuits in a corresponding sub-pixel driving circuit column, and the other data line in the data line group is separately coupled with even-numbered sub-pixel driving circuits in the corresponding sub-pixel driving circuit column; the display substrate further comprises a plurality of first signal lines, the first signal lines are used for transmitting first signals having a stable potential, and at least part of the orthographic projection of each first signal line on a base substrate is located between the orthographic projections of the two adjacent data lines in a corresponding data line group on the base substrate.
