Claim 14:
15. The display substrate according to claim 1, further comprising:
a first gate insulation layer located on one side of the base substrate adjacent to the gate of the at least one first thin film transistor and covering the active layer of the at least one first thin film transistor;
a second gate insulation layer located on one side of the first gate insulation layer away from the base substrate and covering the gate of the at least one first thin film transistor; and
an interlayer insulation layer located on one side of the second gate insulation layer away from the base substrate;
wherein the source and the drain of the at least one first thin film transistor are located on one side of the interlayer insulation layer away from the base substrate, and connected to the active layer through at least one first via hole penetrating through the interlayer insulation layer, the second gate insulation layer and the first gate insulation layer.
