Abstract
A display substrate and a display device are provided. The display substrate includes: a base substrate, and a low temperature poly-silicon thin film transistor and a metal oxide thin film transistor on the base substrate; the low temperature poly-silicon thin film transistor includes: a low temperature poly-silicon semiconductor layer, a first gate insulating layer, a first gate electrode, a first interlayer insulating layer, a first source electrode, and a first drain electrode; the metal oxide thin film transistor includes: a metal oxide semiconductor layer, a second gate insulating layer, a second gate electrode, a second interlayer insulating layer, a passivation layer, a second source electrode, and a second drain electrode; the second source electrode is on a side of the metal oxide semiconductor layer close to the base substrate; and the second drain electrode is on a side of the metal oxide semiconductor layer away from the base substrate.
