Abstract
A display substrate and a display device are provided. The display substrate includes sub-pixels which are arranged in a sub-pixel array in a first direction and a second direction. At least one sub-pixel includes a first transistor, a second transistor, a third transistor, and a storage capacitor. An active layer of the third transistor includes a body region and a first via hole region successively arranged in the first direction and electrically connected with each other; a first electrode of the third transistor is electrically connected to the first via hole region through a first via hole which is shifted in the second direction with respect to the body region, allowing the active layer incudes a first active layer side connecting the body region and the first via hole region; an extension direction of the first active layer side intersects with both the first direction and the second direction.
