1. A display substrate, comprising:
a first display region and a second display region, wherein
the first display region comprises a plurality of first pixels, wherein each first pixel comprises a passive light-emitting device, the second display region comprises a plurality of second pixels, wherein each second pixel comprises an active light-emitting device and a pixel drive circuit electrically connected to the active light-emitting device; the first display region comprises a plurality of first driving signal wire groups, one first driving signal wire group corresponds to a first pixel row; the first pixel row comprises one row of the first pixels, and the first driving signal group comprises a plurality of first driving signal wires, which is connected to an anode of the passive light-emitting device of the first pixel of a corresponding first pixel row; the first display region comprises an anti-diffraction region, which is provided with an anti-diffraction structure, and the anti-diffraction structure is configured to reduce the diffraction intensity of the first driving signal wire groups;
wherein the anti-diffraction structure comprises a plurality of shield parts, which correspond to the first driving signal wire groups one-to-one, and the shield parts are located on one side of the first driving signal wire groups close to a substrate of the display substrate; and
on a plane parallel to the substrate, in the anti-diffraction region, an orthographic projection of a first driving signal wire of the first driving signal wire group is located in an orthographic projection of a corresponding shield part.
