Abstract
A display substrate and a display device are provided. The display substrate includes a base substrate and a plurality of subpixels provided on the base substrate. Each subpixel includes a pixel circuit. The plurality of subpixels include first subpixels. The display substrate further includes power lines. Each power line is configured to provide a first supply voltage for the corresponding first subpixels, the power line is provided on a side of the pixel electrode of the first subpixel near the base substrate, and the power line includes a power line main body and a power line protrusion protruded from the power line main body. The power line protrusion is at least partially overlapped with the pixel electrode of the first subpixel in a direction perpendicular to the base substrate. The display substrate can effectively improve the display quality.
