Display substrate and display device

A display substrate comprising:

• a base substrate, comprising a display region and a peripheral region at least partially surrounding the display region;
• and
• a plurality of conductive pads, in a bonding region, wherein the bonding region is in the peripheral region, the plurality of conductive pads are arranged along a first direction, and each of the plurality of conductive pads extends along a second direction intersecting the first direction, and comprises:
• a first sub-pad, on the base substrate;
• a first insulating layer, on a side of the first sub-pad away from the base substrate;
• a second sub-pad, on a side of the first insulating layer away from the first sub-pad;
• a second insulating layer, on a side of the second sub-pad away from the first insulating layer;
• a first via, penetrating the first insulating layer, and the second sub-pad being directly connected with the first sub-pad through the first via;
• and
• a second via, penetrating the second insulating layer to expose a part of the second sub-pad,
• wherein at least one first via is provided between the first sub-pad and a corresponding second sub-pad, an orthographic projection of the first via on the base substrate overlaps with an orthographic projection of at least one second via on the base substrate, and at least one second via has a size in the second direction being larger than a size in the first direction.
