Display substrate, manufacturing method therefor, and display device

Abstract

A display substrate, a manufacturing method therefor, and a display device are provided. The display substrate includes a base substrate and at least one transistor disposed on the base substrate, with a transistor including an active layer pattern disposed on the base substrate; a first source-drain electrode disposed on the base substrate and electrically connected with the active layer pattern; a first gate electrode disposed on a side of the active layer pattern away from the base substrate, the first gate electrode and the active layer pattern having overlapped orthographic projections on the base substrate and are not in contact with each other; a second source-drain electrode disposed on a side of the active lay pattern away from the base substrate and including a first sub-electrode and a second sub-electrode connected with each other, the second sub-electrode is located on a side of the first sub-electrode close to the first gate electrode, the first sub-electrode is electrically connected with the active layer pattern, the second sub-electrode and the active layer pattern have overlapped orthographic projections on the base substrate and are not in contact with each other.
