A display substrate, display panel, and display device. The display substrate comprises an active layer, a first insulating layer, a first metal layer, a second insulating layer, and a first conductive electrode sequentially arranged on a base; the first metal layer comprises a gate and a first electrode; the portion, exposed through a first via hole formed in the first insulating layer, of the active layer comprises first and second sub-portions; the first electrode is in lap joint with the first sub-portion by the first via hole; a second via hole is formed in the second insulating layer and located on the side, distant from the gate, of a partition boundary of the first and second sub-portions; orthographic projections of the second via hole and the first electrode on the base partially overlap; and the first conductive electrode is connected to the first electrode by the second via hole.
