Display substrate, manufacturing method and display device

The embodiment of the invention provides a display substrate, a manufacturing method and a display device. The display substrate comprises a substrate body and a driving module arranged in the peripheral area of the substrate body. The display substrate further comprises a scanning line, a data line and a first transistor. The scanning line, the data line and the first transistor are arranged in the display area; the scanning lines extend in the first direction, the data lines extend in the second direction, and the first direction intersects with the second direction; a first electrode of the first transistor is coupled with the data line, and the first transistor comprises a first semiconductor layer; the driving module comprises a plurality of second transistors and a connecting line formed on the first metal layer, at least one second transistor is coupled with the connecting line, the second transistor comprises a second semiconductor layer, and the second semiconductor layer is not arranged between the
