The application provides a display substrate and a display device. The display substrate includes: gate lines, data lines, the gate lines and the data lines being arranged to intersect to define sub-pixels, every multiple sub-pixels in a same row constituting a pixel unit; and common electrode lines, each of the common electrode lines is between adjacent two of the gate lines. The display substrate further includes common voltage input line groups intersecting with the common electrode lines. Common voltage input lines in different groups are electrically connected to different ones of the common electrode lines, respectively; and an orthographic projection of every N columns of pixel units on a substrate covers an orthographic projection of a corresponding one of the common voltage input line groups on the substrate, where N is an integer greater than or equal to 1.
