Peripheral wiring structure of display substrate, display substrate display paneland display device

A peripheral wiring structure, comprising a plurality of peripheral wirings formed on a substrate, each peripheral wiring having first opening parts and second opening parts which are arranged alternatively such that the peripheral wiring has a serpentine shape;

• wherein in each two adjacent peripheral wirings,
• a first opening part of a first peripheral wiring opens to a second peripheral wiring, the first opening part of the first peripheral wiring is in one-to-one correspondence with the first opening part of the second peripheral wiring, and centerlines of each pair of the first opening parts corresponding to each other are coincident;
• a second opening part of a second peripheral wiring opens to the first peripheral wiring, the second opening part of the second peripheral wiring is in one-to-one correspondence with the second opening part of the first peripheral wiring, and centerlines of each pair of the second opening parts corresponding to each other are coincident;
• and wherein in each two adjacent peripheral wirings,
• in the first peripheral wiring, a first bent part bulged toward the second peripheral wiring is formed between each two adjacent first opening parts, the first bent part having a first inclined surface connected to a lateral surface of one first opening part, a first top surface connected to the first inclined surface, and a second inclined surface connected to the first top surface and a lateral surface of another first opening part, wherein the first top surface is perpendicular to an arrangement direction of the plurality of peripheral wirings;
• in the second peripheral wiring, a second bent part bulged toward the first peripheral wiring is formed between each two adjacent second opening parts, the second bent part having a third inclined surface connected to a lateral surface of one second opening part, a second top surface connected to the third inclined surface, and a fourth inclined surface connected to the second top surface and a lateral surface of another second opening part, wherein the second top surface is perpendicular to an arrangement direction of the plurality of peripheral wirings;
• in a direction perpendicular to the arrangement direction of the plurality of peripheral wirings, a centerline of each second bent part is located between two adjacent first bent parts, and the third inclined surface of the second bent part is opposite to and parallel to the second inclined surface of one first bent part, and the distance between the third and second inclined surfaces is larger than that between the second and first top surfaces;
• the fourth inclined surface of the second bent part is opposite to and parallel to the first inclined surface of another first bent part, and the distance between the fourth and first inclined surfaces is larger than that between the second and first top surfaces.
