Abstract
Provided are a display substrate and a display device. The display substrate includes a base substrate, and a driving circuit layer and a light-emitting device layer on the base substrate. The display substrate includes a light-transmitting display area and a normal display area, the normal display area surrounds at least a portion of the light-transmitting display area. The normal display area includes multiple normal driving circuits and multiple dummy driving circuits; some dummy driving circuit are used for driving light-emitting devices located in the light-transmitting display area. The display substrate further includes multiple normal data lines coupled to the normal driving circuits; at least one normal data line is coupled to a data signal input terminal through a data lead; an orthographic projection of the data lead onto the base substrate at least partially overlaps an orthographic projection of the dummy driving circuit onto the base substrate.
