Abstract
Embodiments of the present disclosure provide a display substrate and a display device. The display substrate includes a base substrate, a driving circuit layer on the base substrate, a light-emitting structure layer on a side of the driving circuit layer away from the base substrate, and a shield electrode layer on a side of the driving circuit layer proximal to the base substrate. The light-emitting structure layer includes a plurality of light-emitting devices. The driving circuit layer includes a plurality of pixel driving circuits. At least part of transistors in each of the pixel driving circuits are oxide thin film transistors, and at least part of transistors are low-temperature polycrystalline silicon thin film transistors.
