Abstract: A display substrate is provided, including: pixel units on a base substrate; and a first conductive layer, a buffer layer, a semiconductor layer, a first insulation layer, and a second conductive layer which are arranged on the base substrate in a direction away from the base substrate. The display substrate further includes at least one conductive via hole passing through at least the first insulation layer, and at least one conductive plug through which the second conductive portion is electrically connected to the first conductive portion. The first conductive portion includes first and second conductive sub-portions, an orthographic projection of the first conductive sub-portion on the base substrate at least partially overlaps with that of the at least one conductive via hole on the base substrate, and in a third direction, a thickness of the first conductive sub-portion is greater than that of the second conductive sub-portion.
