Display substrate and display device

The invention provides a display substrate and a display device. The display substrate comprises a substrate base plate, wherein the substrate base plate is provided with a display area and a peripheral area surrounding the display area; the pixel driving circuit comprises a control module and a gating module, the control module is located in the peripheral area, the gating module is located in the display area, the gating module is connected with the multiple light-emitting devices, and the control module is configured to provide driving current for the gating module according to the data voltage signal; the gating module is configured to turn on different light emitting devices in response to different gating signals. According to the display substrate, the area occupied by the pixel driving circuit in the display area is reduced, and the pixel density can be improved.
