Abstract

A display substrate and a display device. The display substrate includes a base substrate and a plurality of sub-pixels on the base substrate. Each sub-pixels includes a pixel circuit. The plurality of sub-pixels include a first sub-pixel. The compensation sub-circuit of the first sub-pixel includes a first electrode, a second electrode, and a connection portion between the first electrode and the second electrode. The first drive electrode of the light-emitting element of the first sub-pixel includes a first main body portion including a first side parallel to a certain direction, and a first protruding portion protruding from the first side of the first main body portion. The first protruding portion at least partially overlaps with the connection portion of the compensation sub-circuit of the first sub-pixel in a direction perpendicular to the base substrate. The light-emitting element of the first sub-pixel is configured to emit green light.
