Optionally, taking the trace shown in fig. 1 as an example, the trace includes at least two second trace segments 102, and two adjacent second trace segments 102 are respectively connected to a first trace segment 101 through a contact hole 103.
Specifically, as shown in fig. 1, the first running line segment 101 and the second running line segment 102 may be multiple, and the first running line segment 101 and the second running line segment 102 are arranged at intervals along the first direction X, so that by setting the multiple first running line segments 101 and the multiple second running line segments 102 to transmit signals to corresponding portions (such as transistor gates or source drains) in the display panel, stress caused by bending can be further released, and the risk of breaking the first running line segment 101 or the second running line segment 102 is reduced. Meanwhile, when the length of the display panel in the first direction X is fixed, the stress generated when the display panel is bent is further released by bending at least one of the first running line segment 101 and the second running line segment 102 to further extend the length of the first running line segment 101 or the second running line segment 102. As shown in fig. 1, the first routing segment 101, the second routing segment 102 and the first insulating layer 201 are island-shaped, and when the display panel is bent, stress applied to the plurality of first routing segments 101 arranged at intervals is not accumulated, so that the first routing segments 101 are prevented from being broken due to stress accumulation when being of a whole structure; stress on the plurality of second route segments 102 which are arranged at intervals cannot be gathered, so that the second route segments 102 are prevented from being broken due to stress gathering when being of a whole structure; meanwhile, stress cannot be gathered when the first insulating layer 201 in an island shape is bent, so that the first wiring section 101 or the second wiring section 102 is prevented from being broken due to excessive gathering of the stress of the first insulating layer 201, and the working stability of the display panel is improved.

The planar shape of the second trace segment 102 is the same as that of the portion of the first insulating layer 201 in contact with the second trace segment, which means that the second trace segment 102 corresponding to the first groove 2011 only extends along the first groove 2011, and does not fill the first groove 2011.
Optionally, fig. 6 is a schematic structural diagram of another trace in the display panel provided in the embodiment of the present invention, and referring to fig. 6, a plurality of first grooves are disposed in a portion of the first insulating layer 201, which is in contact with the second trace segment 102.
Specifically, when the display panel includes a plurality of second routing segments 102, a plurality of first grooves 2011 may be disposed at a portion of the first insulating layer 201 corresponding to at least one second routing segment 102, so that when the second routing segment 102 is laid along the first grooves 2011, the length of the second routing segment 102 is further increased, and when the display panel is bent, the bending stress applied to the second routing segment 102 is further released, so as to further avoid the second routing segment 102 from being broken, and improve the working stability of the display panel.
Preferably, the first grooves 2011 are evenly distributed.
Specifically, as shown in fig. 6, a plurality of first grooves 2011 corresponding to one second routing segment 102 are uniformly distributed, that is, intervals between the plurality of first grooves 2011 are the same, when the display panel is bent, at this time, the second routing segment 102 is also laid along the uniformly distributed first grooves 2011, distribution of bent portions on the second routing segment 102 is also relatively uniform, and when the display panel is bent, bending stress on each portion of the second routing segment 102 is relatively uniform, so that a certain portion of the second routing segment 102 is further prevented from being broken due to too large bending stress, risk of breaking the second routing segment is further reduced, and working stability of the display panel is improved.
Preferably, the plurality of first recesses 2011 have the same depth.
Specifically, as shown in fig. 6, all the first recesses 2011 may have the same thickness in the second direction Y, and at this time, all the first recesses 2011 may be prepared by only one mask process, which is relatively simple in process and beneficial to reducing the process cost.

Specifically, after the first insulating layer 201 is manufactured, the first insulating layer 201 may be directly etched by using a mask process, and the first insulating layer 201 is etched through, so that when the second routing segment 102 is laid along the first groove 2011, the length of the second routing segment 102 is further extended, and the risk of fracture when the second routing segment 102 is bent is further reduced.
Optionally, fig. 8 is a schematic structural diagram of another trace in the display panel according to the embodiment of the present invention, and referring to fig. 8, the display panel further includes a second insulating layer 202; the second insulating layer 202 is positioned on one side of the first wire segment 101 away from the second wire segment 102; the first recess 2011 extends to the inside of the second insulating layer 202.
Specifically, after the first insulating layer 201 is etched to form a groove penetrating through the first insulating layer 201, further etching may be performed, so that the groove extends into the second insulating layer 202, and when the second routing segment 102 is laid along the first groove 201, the length of the second routing segment 102 is further extended, thereby further reducing the risk of fracture when the second routing segment 102 is bent.
Optionally, referring to fig. 1, at least one second groove 2021 is disposed on the second insulating layer 202, the first wire segment 101 covers the second groove, and the first wire segment 101 has the same planar shape as the portion of the second insulating layer 202 in contact with the first wire segment 101.
Specifically, the second insulating layer 202 can be etched by using a halftone mask, only a part of the second insulating layer 202 is etched away, the second insulating layer 202 cannot be etched through, at least one second groove 2021 is formed in the second insulating layer 202, and then when the first wire segment 101 is manufactured, the first wire segment 101 is only laid along the second groove 2021, at this time, the length of the first wire segment 101 is larger than the length of the first wire segment 101 when the first wire segment 101 is tiled in the first direction X, so that the stress on the first wire segment 101 when the display panel is bent is effectively released, the first wire segment 101 is prevented from being broken, and the working stability of the display panel is improved. The planar shape of the first trace segment 101 is the same as that of the portion of the first insulating layer 201 in contact with the second trace segment, which means that the first trace segment 101 corresponding to the second groove 2021 is only laid along the second groove 2021, and does not fill the second groove 2021.

Specifically, after the second wire segment 102 is manufactured, a layer of third insulating layer 301 may be prepared on the second wire segment 102, and since the first wire segment 101 and the second wire segment 102 are both of metal structures, if the first wire segment and the second wire segment are directly exposed to the external environment, the first wire segment and the second wire segment will be damaged by corrosion of water, oxygen, and the like, the second wire segment 102 is covered by the third insulating layer 301, so that the second wire segment 102 is prevented from being corroded, and the working stability of the display panel is further improved.

Specifically, the portion of the third insulating layer 301 in contact with the second routing segment 102 has the same planar shape as the second routing segment 102, which can be understood as the third insulating layer 301 is laid along the second routing segment 102, and since the second routing segment 102 does not fill the first groove, that is, it can be further understood that a third groove 3011 is formed in the portion of the third insulating layer 301 corresponding to the first groove, at this time, the thickness of each portion of the third insulating layer 301 is consistent along the first direction X, thereby avoiding the problem that the stress of each portion is inconsistent due to inconsistent film thickness of each portion of the third insulating layer 301 when the third insulating layer is bent, so that the third insulating layer 301 is broken, further avoiding the problem that the second routing segment 102 is broken due to the breakage of the third insulating layer 301, and improving the working stability of the display panel.
Fig. 11 is a schematic structural diagram of a display device according to an embodiment of the present invention, and referring to fig. 11, a display device 20 includes a display panel 19 according to any embodiment of the present invention, and the display device 20 may be a mobile phone, a tablet, a computer, or a wearable device. The display panel provided by any embodiment of the invention has the same beneficial effects, and the description is omitted here.
