Display substrate and display device

A displaying base board, wherein the displaying base board comprises a displaying region and a peripheral region surrounding the displaying region;

• the peripheral region further comprises a plurality of wirings and a driving circuit that is located on one side of the displaying region, and the plurality of wirings are electrically connected to the driving circuit, and are located on any one of two opposite sides of the driving circuit in a first direction, wherein the first direction refers to a direction from the displaying region pointing to the driving circuit;
• the plurality of wirings include at least a plurality of clock-signal lines and a plurality of power-supply-signal lines;
• a spacing between at least one instance of the power-supply-signal lines and the displaying region in the first direction is less than a spacing between at least one instance of the clock-signal lines and the displaying region in the first direction;
• the driving circuit comprises a plurality of shift registers that are cascaded;
• at least one instance of the wirings comprises a plurality of first line segments and second line segments, and neighboring instances of the first line segments are electrically connected by the second line segments;
• and
• a width of each of the second line segments in the first direction is less than a width of each of the first line segments in the first direction, each of the first line segments comprises a first sub-line segment and a second sub-line segment that are connected in parallel, the first sub-line segment is of a double-layer structure, and the second sub-line segment is of a double-layer structure.
