Abstract
Provided is a gate driving circuit. The gate driving circuit includes a plurality of first transistors; wherein at least one first target transistor of the plurality of first transistors includes a first light-shielding layer disposed on a side of a base substrate, the first light-shielding layer being made of a conductive material; and a first gate metal layer and a first source/drain metal layer disposed on a side of the first light-shielding layer away from the base substrate; wherein the first light-shielding layer is connected to the first gate metal layer.
