Display device, display panel and method of manufacturing display panel

A method of manufacturing a display panel, comprising:

• forming a pixel driving circuit on a substrate, the pixel driving circuit comprising a storage capacitor comprising a first transparent electrode plate disposed adjacent to the substrate and a second transparent electrode plate disposed away from the substrate, an orthographic projection of the first transparent electrode plate on the substrate located within an orthographic projection of the second transparent electrode plate on the substrate, the first transparent electrode plate and the second transparent electrode plate are formed with a first half-tone mask;
• forming a planarization layer on a side of the pixel driving circuit away from the substrate, and forming a light-emitting structure on a side of the planarization layer away from the substrate, wherein an orthographic projection of the light-emitting structure on the substrate at least partially overlaps with an orthographic projection of the storage capacitor on the substrate.
