the display panel comprises opening support structures located between the first substrate and the second substrate, and the opening support structures are at least located in a sub-area corresponding to a largest one of first spacings, wherein the traveling line area comprises a plurality of sub-areas, and each of the first spacings is a largest one of spacings between every two adjacent connection segments in a sub-area in the first direction, and different first spacings correspond to different sub-areas.

2. The display panel according to claim 1 , wherein orthographic projections of the opening support structures onto the second substrate do not overlap with orthographic projections of the connection segments onto the second substrate.

3. The display panel according to claim 1 , comprising a plurality of opening support structures arranged in at least a part of the sub-areas; and
areas of orthographic projections of the opening support structures onto the second substrate are same, and distribution densities of the opening support structures are positively correlated to the first spacings corresponding to the sub-areas where the opening support structures are located; or
areas of orthographic projections of the opening support structures onto the second substrate are positively correlated to the first spacings corresponding to the sub-areas where the opening support structures are located.

4. The display panel according to claim 1 , comprising a plurality of opening support structures, and areas of orthographic projections of the opening support structures onto the second substrate are same; and
at least a part of the sub-areas are connected with the opening area, the sub-areas connected with the opening area are connected with each other to constitute a closed area, and the opening support structures located in the closed area are distributed uniformly at an edge of the opening area.

5. The display panel according to claim 4 , wherein the opening support structures are connected with each other to constitute an annular structure surrounding the opening area.

6. The display panel according to claim 1 , wherein each of the opening support structure comprises a layer structure and a support structure arranged in a stack, and an orthographic projection of the support structure onto the second substrate at least partially overlaps with an orthographic projection of the layer structure onto the second substrate.

7. The display panel according to claim 6 , wherein the orthographic projection of the support structure onto the second substrate falls into the orthographic projection of the layer structure onto the second substrate.

8. The display panel according to claim 6 , comprising an array substrate and an opposite substrate opposite to each other, and the first substrate is an underlying substrate in the array substrate, and the second substrate is an underlying substrate in the opposite substrate; or the second substrate is an underlying substrate in the array substrate, and the first substrate is an underlying substrate in the opposite substrate; and
the support structures are arranged between the array substrate and the opposite substrate, and the layer structures are located in the array substrate or the opposite substrate.

9. The display panel according to claim 8 , further comprising spacers located between the array substrate and the opposite substrate; and
a shape and material of the support structures are identical to those of the spacers.

10. The display panel according to claim 8 , wherein the layer structures are located in the opposite substrate; and
the opposite substrate comprises color-resist blocks arranged on a side thereof facing the array substrate, and the layer structures are arranged at a layer same as a layer where the color-resist blocks are arranged.

11. The display panel according to claim 10 , wherein the color-resist blocks comprise red color-resist blocks, blue color-resist blocks, and green color-resist blocks; and
the layer structures are made of a material same as at least one of the red color-resist blocks, the blue color-resist blocks, or the green color-resist blocks.

12. The display panel according to claim 11 , wherein the layer structures are of a size same as that of the color-resist blocks.

13. The display panel according to claim 11 , wherein the layer structures are an annular structure surrounding the opening area.
