Abstract
The present disclosure provides a display substrate, a manufacturing method thereof, and a display device. The display substrate comprises a base substrate, and a first thin film transistor and a second thin film transistor formed on the base substrate, wherein a first active layer of the first thin film transistor is made of low-temperature polysilicon, and a second active layer of the second thin film transistor is made of a metal oxide. The display substrate further comprises a first barrier layer on a side of the second active layer close to the base substrate and a second barrier layer on a side of the second active layer away from the base substrate. The orthographic projection of the second active layer onto the base substrate falls within the orthographic projections of the first barrier layer and the second barrier layer onto the base substrate.
