1. A display panel, comprising:
a substrate;
a light-emitting structure disposed on the substrate; and
a pixel driving circuit disposed between the substrate and the light-emitting structure, the pixel driving circuit comprising a storage capacitor, an orthographic projection of the storage capacitor on the substrate at least partially overlapping with an orthographic projection of the light-emitting structure on the substrate;
wherein the storage capacitor comprises a first transparent electrode plate and a second transparent electrode plate, the first transparent electrode plate is disposed adjacent to the substrate and the second transparent electrode plate is disposed away from the substrate, and an orthographic projection of the first transparent electrode plate on the substrate is located within an orthographic projection of the second transparent electrode plate on the substrate;
wherein the display panel further comprises a light-shielding layer; the pixel driving circuit comprises a first electrode, a second electrode, and an active region; the first electrode and the second electrode are electrically connected to the active region, and the first electrode is further electrically connected to the second transparent electrode plate; the light-shielding layer is disposed on a side of the active region adjacent to the substrate and is electrically connected to the first electrode;
wherein an orthographic projection of the first electrode on the substrate completely overlaps with an orthographic projection of the light-shielding layer on the substrate, such that a position and an area of the orthographic projection of the first electrode on the substrate are same as a position and an area of the orthographic projection of the light-shielding layer on the substrate respectively.
