Abstract
A display substrate, a display panel, and a display device are provided. The display substrate includes: a base substrate; a plurality of sub-pixels in the display pixel region, wherein each sub-pixel includes a pixel driving circuit; a plurality of first dummy sub-pixel structures on the base substrate and in the first dummy pixel region, wherein at least one first dummy sub-pixel structure includes a compensation capacitor; and a plurality of scan signal lines arranged on the base substrate and configured to transmit a scan signal to the pixel driving circuit. At least one scan signal line extends through the display pixel region and the first dummy pixel region, and the at least one scan signal line is electrically connected to the pixel driving circuit of each sub-pixel in a row of sub-pixels and is further electrically connected to the compensation capacitor of the at least one first dummy sub-pixel structure.
