Abstract
A display substrate and a display device are provided. The display substrate includes a base substrate and sub-pixels on the base substrate. At least one sub-pixel includes a first transistor, a second transistor and a storage capacitor. The display substrate further includes an extension portion protruding from the gate electrode of the first transistor, and the extension portion is extended from the gate electrode of the first transistor in the second direction; the extension portion is at least partially overlapped with the first electrode of the second transistor in a direction perpendicular to the base substrate and is electrically connected with the first electrode of the second transistor; in the first direction, the extension portion has a second side closest to the second capacitor electrode, and the second side is recessed in a direction away from the second capacitor electrode.
