Abstract: A display substrate is provided. The display substrate includes a base substrate including a display region and a peripheral region, a gate scan driving circuit, a light-emitting control scan driving circuit, a first power line, a first planarization layer, a second planarization layer and a first shielding layer and a second shielding layer. The first planarization layer and the second planarization layer further include an open slot. The second shielding layer extends from a region corresponding to the light-emitting control scan driving circuit to a region corresponding to the gate scan driving circuit and covers the open slot. In an area where the second shielding layer is close to the open slot, an orthographic projection of the second shielding layer covering the open slot on the base substrate at least overlaps with an orthographic projection of the first shielding layer on the base substrate.
