Abstract
A display substrate and a manufacturing method thereof and a display device are provided. The display substrate includes a base substrate and sub-pixels on the base substrate. The sub-pixels are arranged in a sub-pixel array. At least one sub-pixel includes a first transistor, a second transistor, a third transistor and a storage capacitor. The first electrode of the third transistor is electrically connected to an active layer of the third transistor through a first via hole, and the first electrode of the third transistor is configured to be electrically connected to the light emitting element through a second via hole; the first via hole and the second via hole are at least partially overlapped with each other in a direction perpendicular to the base substrate.
