Display substrate with a bonding pad including conductive parts in different layers and method for manufacturing the same, display device

A display substrate, having a display area and a bonding area positioned on at least one side of the display area, the display substrate comprises:

• a base;
• a first conductive layer arranged on the base and positioned in the display area;
• the first conductive layer comprises a plurality of gate lines;
• a light shielding layer arranged on a side of the first conductive layer proximal to the base, and an orthographic projection of the light shielding layer on the base at least covers orthographic projections of the plurality of gate lines on the base;
• and
• a plurality of bonding pads arranged on the base at intervals and positioned in the bonding area;
• orthographic projections of at least a portion of the plurality of bonding pads on the base are not overlapped with the orthographic projection of the light shielding layer on the base,
• wherein the plurality of bonding pads comprises functional bonding pads and redundant b onding pads,
• orthographic projections of the redundant bonding pads on the base are at least partially not overlapped with the orthographic projection of the light shielding layer on the base, and
• orthographic projections of the functional bonding pads on the base are at least partially o verlapped with the orthographic projection of the light shielding layer on the base,
• the display substrate further comprises an auxiliary electrode and a common electrode ar ranged on a side of the first conductive layer away from the base, and the auxiliary electrode and the common electrode are sequentially arranged along a direction away from the base and are el ectrically coupled with each other, and orthographic projections of the auxiliary electrode and the common electrode on the base are at least partially overlapped with each other, wherein each of the plurality of redundant bonding pads comprises a first conductive part
• and a second conductive part which are arranged on the side of the first conductive layer away fr om the base, and are electrically coupled, the first conductive part and the common electrode are arranged in a same layer and are made of a same material, and the second conductive part and t he auxiliary electrode are arranged in a same layer and are made of a same material.
