1. A display substrate, comprising a display area and an overlapping area surrounding the display area, and further comprising a base substrate and a light-emitting functional layer and an electrode layer stacked on the base substrate, wherein
the overlapping area comprises two first overlapping areas, the two first overlapping areas extend in a first direction and are respectively located at opposite sides of the display area, and each of the first overlapping areas is provided with a plurality of signal wires;
the light-emitting functional layer comprises a first portion located in the display area and two second portions respectively located in the two first overlapping areas, each of the second portions comprises a plurality of first blocks spaced in the first direction, and each of the first blocks is connected to the first portion;
the electrode layer comprises a third portion located in the display area and two fourth portions respectively located in the two first overlapping areas, each of the fourth portions comprises a plurality of second blocks spaced in the first direction, and each of the second blocks is connected to the third portion; and
in one same first overlapping area, an orthographic projection of each of the first blocks on the base substrate does not overlap at least partially with an orthographic projection of one of the second blocks on the base substrate, and each of the second blocks corresponds to and is electrically connected to an end of one of the signal wires.
