Abstract

The present disclosure provides a wiring structure, a display substrate and a display device, and belongs to the field of display technology. The wiring structure of the present disclosure comprises a body portion provided with hollow patterns; the body portion has a first side and a second side which are provided opposite to each other along an extending direction of the wiring structure, and both the first and second sides are wavy; the body portion comprises a plurality of conductive elements sequentially connected along the extending direction of the wiring structure; and in each conductive element, a length of a protruding portion on the first side in the extending direction of the wiring structure is different from that of a protruding portion on the second side in the extending direction of the wiring structure.

First claim

What is claimed is:

1. A wiring structure, comprising a plurality of body portions provided with hollow patterns, wherein
each body potion of the plurality of the body portions has a first side and a second side which are provided opposite to each other along an extending direction of the wiring structure, and both the first and second sides are wavy; and
each body potion of the plurality of the body portions comprises a plurality of conductive elements sequentially connected along the extending direction of the wiring structure; and at least one conductive element of the plurality of conductive elements each comprises at least one protruding portion on the first side and at least one protruding portion on the second side;
wherein each body potion of the plurality of the body portions is self-continuous along the extending direction of the wiring structure, and a first side of one of every two adjacent body portions and a second side of the other of the two adjacent body portions are joined together to form an integral structure, and
the hollow patterns in the two adjacent body portions are staggered so that none of the hollow patterns in one of the two adjacent body portions is aligned with a hollow pattern in the other of the two adjacent body portions in a direction perpendicular to the extending direction of the wiring structure.

2. The wiring structure of claim 1 , wherein in each of the at least one conductive element, a curvature degree of the protruding portion on the first side is different from that of the protruding portion on the second side.

3. The wiring structure of claim 1 , wherein any two adjacent protruding portions on the first side have different curvature degrees.

4. The wiring structure of claim 1 , wherein any two adjacent protruding portions on the second side have different curvature degrees.

5. The wiring structure of claim 1 , wherein any two adjacent protruding portions on the first side have different curvature degrees, and any two adjacent protruding portions on the second side have different curvature degrees.

6. The wiring structure of claim 3 , wherein each of the at least one conductive element comprises one protruding portion on the first side and one protruding portion on the second side.

7. The wiring structure of claim 6 , wherein every two adjacent conductive elements are centrally symmetrical to each other in structure.

8. The wiring structure of claim 3 , wherein each of the first and second sides is provided with at least three protruding portions having different curvature degrees.

9. The wiring structure of claim 8 , wherein from at least one pair of two adjacent conductive elements in the body portion, one of the two adjacent conductive elements comprises one protruding portion on the first side and two protruding portions on the second side, and the other of the two adjacent conductive elements comprises two protruding portions on the first side and one protruding portion on the second side.

10. The wiring structure of claim 9 , wherein the conductive element comprising one protruding portion on the first side and two protruding portions on the second side and the other conductive element adjacent to the conductive element and comprising two protruding portions on the first side and one protruding portion on the second side are centrally symmetrical to each other in structure.

11. The wiring structure of claim 1 , wherein each of the plurality of conductive elements is provided with one hollow pattern.

12. The wiring structure of claim 1 , wherein the hollow pattern has a shape of one of circles, ellipses, rectangles, and rhombuses.

13. The wiring structure of claim 1 , wherein the plurality of conductive elements are formed to be an integral structure.

14. A display substrate, comprising a base and a wiring structure provided on the base, wherein the wiring structure is the wiring structure of claim 1 .

15. A display device, comprising a display substrate, wherein the display substrate is the display substrate of claim 14 .

16. The wiring structure of claim 4 , wherein each of the at least one conductive element comprises one protruding portion on the first side and one protruding portion on the second side.

17. The wiring structure of claim 5 , wherein each of the at least one conductive element comprises one protruding portion on the first side and one protruding portion on the second side.

18. The wiring structure of claim 4 , wherein each of the first and second sides is provided with at least three protruding portions having different curvature degrees.
