[0117] like Figures 1 to 4As shown, the first embodiment of the present application provides a display panel 10, the display panel 10 includes: a substrate 100; a touch layer 200, located on one side of the substrate 100, the touch layer 200 includes a first conductive layer 210, an insulating layer 230, and a second conductive layer 220 stacked in sequence, the second conductive layer 220 is located on the side of the first conductive layer 210 away from the substrate 100; wherein the touch layer 200 includes a touch structure 300, the touch structure 300 includes a first touch structure 310 located on the first conductive layer 210 and a second touch structure 310 located on the second conductive layer 220; The first touch structure 310 includes a first segment 311, and the second touch structure 320 includes a second segment 321. The first segment 311 and the second segment 321 both extend along the first direction X, and the orthographic projection of the first segment 311 on the substrate 100 and the orthographic projection of the second segment 321 on the substrate 100 at least partially overlap; wherein, the edge of the first segment 311 on at least one side of the second direction Y and the orthographic projection of the edge of the second segment 321 on the same side of the second direction Y on the substrate 100 are staggered, and the first direction X and the second direction Y intersect.

[0118] According to the display panel 10 of the embodiment of the present application, the display panel 10 includes a substrate 100 and a touch layer 200. The touch layer 200 includes a first conductive layer 210, an insulating layer 230, and a second conductive layer 220. The touch structure 300 of the touch layer 200 includes a first touch structure 310 located in the first conductive layer 210 and a second touch structure 320 located in the second conductive layer 220. The first touch structure 310 and the second touch structure 320 are used to implement the touch function of the display panel 10. For example, the first touch structure 310 and the second touch structure 320 can both be touch connection lines to implement the transmission of touch signals. The first segment 311 of the first touch structure 310 and the second segment 321 of the second touch structure 320 overlap, and the edge of at least one side of the first segment 311 in the second direction Y and the edge of the second segment 321 on the same side are staggered in their orthographic projections on the substrate 100, which can improve the overlap of the orthographic projections of the edges of the first segment 311 and the second segment 321 in the second direction Y on the substrate 100, resulting in stress concentration on the insulating layer 230 between the first segment 311 and the second segment 321, and then the problem of film breakage of the insulating layer 230, thereby improving the problem of screen cracks caused by the external folding and arching of the display panel 10 or black spots caused by packaging failure, thereby improving the performance of the display panel 10.

[0119] Optionally, the display panel 10 is a foldable display panel 10, and the display panel 10 has at least an inward folding state, in which the display surfaces of the display panel 10 are close to each other. When the display panel 10 in the inward folding state falls, the bending area of ​​the display panel 10 is stressed to bend outward, which may easily lead to screen cracks or black spots caused by packaging failure. Therefore, the embodiment of the present application can improve the problem of screen cracks or black spots caused by packaging failure caused by the outward folding of the screen of the display panel 10, and improve the performance of the display panel 10.

[0120] There are many ways to set the substrate 100. For example, the substrate 100 may include a substrate and an array substrate arranged on the substrate. Alternatively, the substrate 100 is the substrate. Alternatively, the substrate 100 includes a buffer layer and a support plate on a side away from the substrate.

[0122] like Figure 1 and Figure 5 As shown, in some optional embodiments, the orthographic projection of the first segment 311 on the substrate 100 has a first edge 311a and a second edge 311b that are relatively arranged in the second direction Y, and the orthographic projection of the second segment 321 on the substrate 100 has a third edge 321a and a fourth edge 321b that are relatively arranged in the second direction Y, the first edge 311a and the third edge 321a are located on the same side, the second edge 311b and the fourth edge 321b are located on the same side, the first edge 311a and the third edge 321a are staggered, and / or the second edge 311b and the fourth edge 321b are staggered.

[0123] The first edge 311a and the third edge 321a are staggered; or, the second edge 311b and the fourth edge 321b are staggered; or, the first edge 311a and the third edge 321a are staggered, and the second edge 311b and the fourth edge 321b are staggered.

[0125] In these optional embodiments, the first edge 311a and the third edge 321a are staggered, which can improve the overlap of the orthographic projections of the first edge 311a and the third edge 321a on the substrate 100, resulting in the problem of stress concentration in the insulating layer 230 between the first segment 311 and the second segment 321 on the side close to the first edge 311a and the third edge 321a; the second edge 311b and the fourth edge 321b are staggered, which can improve the overlap of the orthographic projections of the second edge 311b and the fourth edge 321b on the substrate 100, resulting in the problem of stress concentration in the insulating layer 230 between the first segment 311 and the second segment 321 on the side close to the second edge 311b and the fourth edge 321b. One side is prone to stress concentration problems; the first edge 311a and the third edge 321a are staggered, and the second edge 311b and the fourth edge 321b are staggered, which can improve the overlap of the orthographic projections of the first edge 311a and the third edge 321a, the second edge 311b and the fourth edge 321b on the substrate 100, resulting in the insulating layer 230 between the first segment 311 and the second segment 321. The two sides in the second direction Y are prone to stress concentration problems, further reducing the risk of stress concentration in the insulating layer 230, thereby improving the screen cracks caused by the external folding and arching of the display panel 10 or the black spots caused by packaging failure, thereby improving the performance of the display panel 10.

[0129] The first edge 311a and / or the second edge 311b is located between the third edge 321a and the fourth edge 321b, which means that the orthographic projection of the first edge 311a and / or the second edge 311b on the substrate 100 is located between the orthographic projection of the third edge 321a and the fourth edge 321b on the substrate 100; the third edge 321a and / or the fourth edge 321b is located between the first edge 311a and the second edge 311b, which means that the orthographic projection of the third edge 321a and / or the fourth edge 321b on the substrate 100 is located between the orthographic projection of the first edge 311a and the second edge 311b on the substrate 100.

[0130] In these optional embodiments, the first edge 311a and the second edge 311b may be arranged in various ways, for example, the first edge 311a may be located between the third edge 321a and the fourth edge 321b; or, the second edge 311b may be located between the third edge 321a and the fourth edge 321b; or, the first edge 311a and the second edge 311b may be located between the third edge 321a and the fourth edge 321b. The third edge 321a and the fourth edge 321b may be arranged in various ways, for example, the third edge 321a may be located between the first edge 311a and the second edge 311b; or, the fourth edge 321b may be located between the first edge 311a and the second edge 311b; or, the third edge 321a and the fourth edge 321b may be located between the first edge 311a and the second edge 311b. That is, the first edge 311a is misaligned with the third edge 321a, and the second edge 311b is misaligned with the fourth edge 321b, which can improve the overlap of the orthographic projections of the first edge 311a with the third edge 321a, the second edge 311b and the fourth edge 321b on the substrate 100, resulting in the problem of stress concentration on both sides of the insulating layer 230 between the first segment 311 and the second segment 321 in the second direction Y, further reducing the risk of stress concentration in the insulating layer 230, thereby improving the problem of screen cracks caused by the external folding and arching of the display panel 10 or black spots caused by packaging failure, thereby improving the performance of the display panel 10.

[0131] like Figure 2 As shown, in some optional embodiments, the insulating layer 230 includes a first flat portion 231, a slope 232, and a second flat portion 233 connected in sequence, the second flat portion 233 is located on the side of the first flat portion 231 facing away from the substrate 100, the slope 232 and the first flat portion 231 have an intersection position, and the orthographic projection of the intersection position on the substrate 100 is located within the orthographic projection of the second segment 321 on the substrate 100.

[0133] In some optional embodiments, the orthographic projections of the first flat portion 231 and the second flat portion 233 on the substrate 100 at least partially overlap with the orthographic projection of the second segment 321 on the substrate 100 .

[0142] In these optional embodiments, the distance between the first edge 311a and the third edge 321a is greater than or equal to 0.5 μm, which can improve the problem that the stress concentration position of the insulating layer 230 is caused by the small distance between the first edge 311a and the third edge 321a, for example, the stress reduction at the intersection position close to the first edge 311a and the third edge 321a is not obvious, and the insulating layer 230 is prone to film breakage.

[0143] In some optional embodiments, the distance d2 between the second edge 311b and the fourth edge 321b is greater than or equal to 0.5 μm. For example, the distance between the second edge 311b and the fourth edge 321b is 0.5 μm, 1 μm, 1.25 μm, 5 μm, etc.

[0145] Optionally, the distance between the first edge 311a and the third edge 321a is equal to the distance between the second edge 311b and the fourth edge 321b, so that the stress distribution of the insulating layer 230 on the side close to the first edge 311a is similar to the stress distribution on the side close to the second edge 311b, thereby improving the uniformity of the stress distribution of the insulating layer 230 and improving the problem of film breakage of the insulating layer 230 caused by stress concentration of the insulating layer 230.

[0146] In some optional embodiments, the distance d1 between the first edge 311a and the third edge 321a is greater than or equal to 1 μm. For example, the distance between the first edge 311a and the third edge 321a is 1 μm, 1.25 μm, 2 μm, 5 μm, etc.

[0147] In these optional embodiments, the distance between the first edge 311a and the third edge 321a is greater than or equal to 1 μm, which can improve the problem that the stress concentration position of the insulating layer 230 is caused by the small distance between the first edge 311a and the third edge 321a, for example, the stress reduction at the intersection position close to the first edge 311a and the third edge 321a is not obvious, and the insulating layer 230 is prone to film breakage.

[0148] In some optional embodiments, the distance d2 between the second edge 311b and the fourth edge 321b is greater than or equal to 1 μm. For example, the distance between the second edge 311b and the fourth edge 321b is 1 μm, 1.25 μm, 2 μm, 5 μm, etc.

[0150] Specifically, when the distance between the first edge 311a and the third edge 321a is 1 μm, and the distance between the second edge 311b and the fourth edge 321b is 1 μm, in the simulation analysis, relative to the scheme in which the orthographic projections of the first edge 311a and the third edge 321a on the substrate 100 coincide, and the orthographic projections of the second edge 311b and the fourth edge 321b on the substrate 100 coincide, the force on the insulating layer 230 at the intersection is reduced by 9%.

[0176] Please also read Figures 1 to 9 , Fig. 9 It is a schematic top view of a display panel provided in an embodiment of the present application.

[0177] like Figures 1 to 9As shown, optionally, the display panel 10 includes a bending axis 11, and at least a portion of the extension direction of the touch structure 300 has an angle with the bending axis 11. For example, the first touch structure 310 has an angle with the bending axis 11, and / or the second touch structure 320 has an angle with the bending axis 11. That is, the extension direction of at least a portion of the touch structure 300 is not arranged parallel to the bending axis 11, so as to avoid the extension direction of the touch structure 300 being arranged parallel to the bending axis 11, which will increase the stiffness mutation of the display panel 10 during the anti-arching process, form a stress concentration point, and thus cause the problem of film layer rupture.

[0178] Optionally, an angle is formed between the extension direction of all touch structures 300 and the bending axis 11, which can further avoid the problem of the extension direction of the touch structure 300 being parallel to the bending axis 11, which will increase the stiffness mutation of the display panel 10 during the reverse arch process, form a stress concentration point, and thus cause the film layer to break.

[0179] Optionally, the angle is greater than 0 degrees. Specifically, it can be 30 degrees, 60 degrees, 70 degrees or 90 degrees. There is an angle between the extension direction of the touch structure 300 and the bending axis 11, so the angle does not include 180 degrees.

[0188] In these optional embodiments, one of the first segment 301 and the second segment 302 is a part of the touch electrode, and the other is a part of the touch connection line. The angle between the interconnected first segment 301 and the second segment 302 is set to be relatively large, which can reduce the stiffness mutation of the interconnected touch electrodes and touch connection lines caused by the display panel 10 during the reverse arching process, and improve the stiffness mutation, which is large and easy to form stress concentration points, thereby causing the film layer to break. In other embodiments, the first segment 301 and the second segment 302 are both parts of the touch connection line, and the angle between the interconnected first segment 301 and the second segment 302 is set to be relatively large, which can reduce the stiffness mutation of the interconnected touch connection lines caused by the display panel 10 during the reverse arching process, and improve the stiffness mutation, which is large and easy to form stress concentration points, thereby causing the film layer to break. In other embodiments, the first section 301 and the second section 302 are both part of the touch electrode, and the angle between the interconnected first section 301 and the second section 302 is set to be relatively large, which can reduce the stiffness mutation of the interconnected touch electrodes caused by the back-arching process of the display panel 10, and improve the problem of large stiffness mutation, which easily forms stress concentration points and causes film breakage.

[0189] like Fig.10b As shown, in some optional embodiments, the connection between the first section 301 and the second section 302 includes a chamfer; more specifically, the chamfer is an arc chamfer.

[0190] In some optional embodiments, an angle is formed between the extension direction of the touch connection line and the bending axis 11 .

[0191] In these optional embodiments, the extension direction of the touch connection line is not parallel to the bending axis 11, so as to avoid the extension direction of the touch connection line being parallel to the bending axis 11, which will increase the sudden change in stiffness of the display panel 10 during the reverse arching process, form a stress concentration point, and thus cause the film layer to break.

[0192] In some optional embodiments, the orthographic projection of the touch structure 300 on the substrate 100 has an edge parallel to the bending axis 11 of the display panel 10 .

[0193] In these optional embodiments, setting at least part of the edge of the touch structure 300 to be parallel to the bending axis 11 can improve the problem of setting the tip of the angle of the touch structure 300 toward or away from the bending axis 11, which will increase the sudden change in stiffness of the display panel 10 during the reverse arch process, form a stress concentration point, and cause film breakage.

[0194] For example, in simulation analysis, the tip of the touch structure 300 with an angle facing or away from the bending axis 11 is replaced with an edge parallel to the bending axis 11, so that the force on the touch structure 300 at the edge is reduced by 3% relative to the tip.

[0197] In these optional embodiments, setting at least a portion of the first side 304 of the touch structure 300 to be parallel to the bending axis 11 can improve the problem that the tip of the angle of the touch structure 300 toward the first gap 303 is set toward or away from the bending axis 11, which will increase the stiffness mutation of the display panel 10 during the anti-arching process, form a stress concentration point, and cause the film layer to break. For example, it can avoid the X-shaped crack caused by stress concentration.

[0198] Optionally, the first sides 304 of the adjacent touch structures 300 facing the first gap 303 are parallel to the bending axis 11, which can further reduce the sudden change in stiffness of the display panel 10 during the backbending process. Optionally, part of the first sides 304 of the plurality of touch structures 300 are parallel to the bending axis 11.

[0201] In these optional embodiments, the first edge 304 is divided into a plurality of interconnected edges, and the angle between any two adjacent edges is set to be larger, so as to reduce the stiffness mutation of the touch structure 300 toward one end of the first gap 303 caused by the back-arching process of the display panel 10, and improve the problem that the stiffness mutation is large and stress concentration points are easily formed, thereby causing the film layer to break.

[0202] See also Fig.13 , Fig.13 FIG. 4 is a partial top view of a display panel in yet another embodiment.

[0203] like Fig.13 As shown, optionally, the first edge 304 includes a curve, which can improve the setting of the tip of the angle of the touch structure 300 toward or away from the bending axis 11, resulting in an increase in the sudden change in stiffness of the screen of the display panel 10 during the reverse arch process, forming a stress concentration point and causing the film layer to break.

[0204] like Fig.11 As shown, in some optional embodiments, the orthographic projection of the touch structure 300 on the substrate 100 further includes a second edge 305 connected to both ends of the first edge 304 , and the angle between the second edge 305 and the bending axis 11 is 45°.

[0205] In these optional embodiments, the angle between the second edge 305 and the bending axis 11 is 45°, which can improve the problem that the stiffness of the display panel 10 suddenly increases during the arching process due to the small angle between the second edge 305 and the bending axis 11, forming a stress concentration point and causing the film layer to break.

[0206] In some optional embodiments, the angle between the first side 304 and the second side 305 is greater than 90°.

[0207] In these optional embodiments, the angle between the first edge 304 and the second edge 305 is set to be larger, which can reduce the stiffness mutation of the touch structure 300 toward one end of the first gap 303 caused by the display panel 10 during the reverse arching process, and improve the problem of large stiffness mutation, which easily forms stress concentration points and thus causes film breakage.

[0208] Optionally, the angle between any two adjacent sides of the orthographic projection of the touch structure 300 on the substrate 100 is greater than 90°, which can reduce the stiffness mutation of the touch structure 300 caused by the back-arching process of the display panel 10, and improve the problem of large stiffness mutation, which easily forms stress concentration points and causes film breakage.

[0209] See also Fig.14 , Fig.14 FIG. 4 is a partial top view of a display panel in yet another embodiment.

[0210] like Fig.14 As shown, optionally, the first touch control structure 310 further includes a first conductive portion 313 , and the second touch control structure 320 further includes a second conductive portion 323 , and the first conductive portion 313 and the second conductive portion 323 are connected via holes.

[0211] Optionally, the orthographic projection of the second conductive portion 323 on the substrate 100 has a seventh edge 323 a and an eighth edge 323 b that are arranged opposite to each other in a third direction Z, and the third direction Z is perpendicular to the bending axis 11 of the display panel 10 .

[0212] Optionally, the seventh edge 323 a is parallel to the bending axis 11 , and the eighth edge 323 b is parallel to the bending axis 11 .

[0213] Optionally, the length d3 of the seventh edge 323 a is 3 μm-15 μm, for example, the length of the seventh edge 323 a is 3 μm, 5 μm, 6 μm, 15 μm, etc.

[0214] In these optional embodiments, the first conductive part 313 and the second conductive part 323 are connected by vias to realize the electrical connection between the first touch structure 310 and the second touch structure 320. The seventh edge 323a and the eighth edge 323b are parallel to the bending axis 11, so the seventh edge 323a and the eighth edge 323b will cause the stiffness of the display panel 10 to suddenly increase during the reverse arching process, forming a stress concentration point, thereby causing the film layer to break. Setting the length of the seventh edge 323a to be less than or equal to 15μm can improve the problem that the stiffness of the second conductive part 323 suddenly increases during the reverse arching process of the display panel 10 due to the excessive length of the seventh edge 323a, forming a stress concentration point, thereby causing the film layer to break. The length of the seventh edge 323a is greater than or equal to 3μm, which can improve the problem that the difficulty of preparing the second conductive part 323 increases due to the small length of the seventh edge 323a.

[0215] In some optional embodiments, the length d4 of the eighth edge 323 b is 3 μm-15 μm. For example, the length of the eighth edge 323 b is 3 μm, 5 μm, 6 μm, 15 μm, etc.

[0216] In these optional embodiments, the length of the eighth edge 323b is less than or equal to 15 μm, which can improve the problem that the stiffness mutation area of ​​the second conductive part 323 is too large due to the length of the eighth edge 323b being too large, resulting in a sudden increase in stiffness during the back-bending process of the display panel 10, forming a stress concentration point, and thus causing the film layer to break. The length of the eighth edge 323b is greater than or equal to 3 μm, which can improve the problem that the difficulty of preparing the second conductive part 323 is increased due to the length of the eighth edge 323b being too small.

[0217] For example, when the length of the seventh edge 323a and the eighth edge 323b is reduced to 3 μm, the force at the first conductive portion 313 and the second conductive portion 323 is reduced by 16% compared to when the length of the seventh edge 323a and the eighth edge 323b is 10 μm.

[0218] In some optional embodiments, the orthographic projection of the second conductive portion 323 on the substrate 100 has a ninth edge 323 c and a tenth edge 323 d that are arranged opposite to each other in the fourth direction W, and the fourth direction W is parallel to the bending axis 11 of the display panel 10 .

The length of the ninth edge 323c is greater than or equal to 3 μm, which can improve the problem that the difficulty of preparing the second conductive part 323 is increased due to the length of the ninth edge 323c being too small.

[0222] In some optional embodiments, the length d6 of the tenth edge 323d is 3 μm-15 μm. For example, the length of the tenth edge 323d is 3 μm, 5 μm, 6 μm, 15 μm, etc.

[0223] In these optional embodiments, the length of the tenth edge 323d is less than or equal to 15 μm, which can improve the problem that the stiffness mutation area of ​​the second conductive part 323 is too large due to the length of the tenth edge 323d being too large, resulting in a sudden increase in stiffness during the back-bending process of the display panel 10, forming a stress concentration point, and thus causing the film layer to break. The length of the tenth edge 323d is greater than or equal to 3 μm, which can improve the problem that the difficulty of preparing the second conductive part 323 is increased due to the length of the tenth edge 323d being too small.

[0224] Optionally, the edge length of the orthographic projection of the first conductive portion 313 on the substrate 100 parallel to the bending axis 11 is 3 μm-15 μm, for example, the edge length is 3 μm, 5 μm, 6 μm, 15 μm, etc.

[0225] In these optional embodiments, the length of the edge of the orthographic projection of the first conductive part 313 on the substrate 100 parallel to the bending axis 11 is less than or equal to 15 μm, which can improve the problem that the stiffness of the display panel 10 increases suddenly during the reverse arching process due to the excessive length of the edge of the first conductive part 313 and the excessive area of ​​the stiffness mutation of the first conductive part 313, thereby forming a stress concentration point and causing the film layer to break. The length of the edge of the orthographic projection of the first conductive part 313 on the substrate 100 parallel to the bending axis 11 is greater than or equal to 3 μm, which can improve the problem that the difficulty of preparing the first conductive part 313 increases due to the small length of the edge of the first conductive part 313.

[0226] Optionally, the edge length of the orthographic projection of the first conductive portion 313 on the substrate 100 that is perpendicular to the bending axis 11 is 3 μm-15 μm, for example, the edge length is 3 μm, 5 μm, 6 μm, 15 μm, etc.

[0227] In these optional embodiments, the length of the edge of the orthographic projection of the first conductive part 313 on the substrate 100 perpendicular to the bending axis 11 is less than or equal to 15 μm, which can improve the problem that the stiffness of the display panel 10 increases suddenly during the reverse arching process due to the excessive length of the edge of the first conductive part 313 and the excessive area of ​​the stiffness mutation of the first conductive part 313, forming a stress concentration point, and thus causing the film layer to break. The length of the edge of the orthographic projection of the first conductive part 313 on the substrate 100 perpendicular to the bending axis 11 is greater than or equal to 3 μm, which can improve the problem that the difficulty of preparing the first conductive part 313 increases due to the small length of the edge of the first conductive part 313.

[0229] like Fig.15 As shown, optionally, the second conductive layer 220 further includes a third chamfered section 325 and a third main body portion 324 , and the third chamfered section 325 is located between the second conductive portion 323 and the third main body portion 324 .

[0230] Optionally, the angle between the third chamfered section 325 and the second conductive portion 323 is an obtuse angle. The angle between the third chamfered section 325 and the second conductive portion 323 refers to the angle between adjacent edges of the third chamfered section 325 and the second conductive portion 323 .

[0231] In these optional embodiments, the angle between the third chamfered section 325 and the second conductive portion 323 is set to be larger, which can reduce the stiffness mutation of the touch structure 300 caused by the display panel 10 during the reverse arching process, and improve the stiffness mutation of the second conductive layer 220, which is large and easily forms stress concentration points, thereby causing the film layer to break.

[0232] In some optional embodiments, the angle between the third chamfered section 325 and the third main body 324 is an obtuse angle. The angle between the third chamfered section 325 and the third main body 324 refers to the angle between adjacent edges of the third chamfered section 325 and the third main body 324.

[0233] In these optional embodiments, the angle between the third chamfered section 325 and the third main body portion 324 is set to be larger, which can reduce the stiffness mutation of the touch structure 300 caused by the display panel 10 during the reverse arching process, and improve the stiffness mutation of the second conductive layer 220, which is large and easily forms stress concentration points, thereby causing the film layer to break.

[0234] In some optional embodiments, the third chamfered section 325 includes a curve.

[0235] When the third chamfered section 325 is a curve, the angle between the third chamfered section 325 and the second conductive portion 323 refers to the angle between the tangent direction of the contact position between the third chamfered section 325 and the second conductive portion 323 and the edge of the second conductive portion 323. The angle between the third chamfered section 325 and the third main body 324 refers to the angle between the tangent direction of the contact position between the third chamfered section 325 and the third main body 324 and the edge of the second conductive portion 323.

[0236] In these optional embodiments, a smooth transition of a curve is adopted between the second conductive portion 323 and the third main body portion 324, which can further reduce the stiffness mutation of the touch structure 300 caused by the back-arching process of the display panel 10, and improve the problem that the stiffness mutation of the second conductive layer 220 is large and stress concentration points are easily formed, thereby causing the film layer to break.

[0237] Optionally, the length of at least part of the edge of the orthographic projection of the touch structure 300 on the substrate 100 that is parallel to the bending axis 11 is reduced to one-fourth to three-fourths of the original length. For example, if the original length of a certain edge is d, the length can be reduced to 0.25d to 0.75d. This can reduce the stiffness mutation area of ​​the touch structure 300, thereby reducing the stiffness mutation of the touch structure 300, and improve the stiffness mutation of the display panel 10 during the reverse arching process, forming a stress concentration point, and thus causing the film layer to break.

[0238] Optionally, the display panel 10 further includes a pixel definition layer, a light emitting layer, a first electrode layer and an encapsulation layer which are located on one side of the substrate 100 and are sequentially stacked along the thickness direction of the display panel 10.

The touch layer 200 includes a first conductive layer 210, an insulating layer 230, and a second conductive layer 220. The extension direction of at least part of the touch connection line is not arranged parallel to the bending axis 11, so as to avoid the extension direction of the touch connection line being arranged parallel to the bending axis 11, which will increase the sudden change in stiffness of the display panel 10 during the anti-arching process, form a stress concentration point, and thus cause the problem of film layer fracture.

[0241] After the above-mentioned improvement, the display panel 10 provided by the present application is subjected to a parallel plate test in an outward folded state. Two parallel plates are used to clamp and squeeze the display panel 10, and the plate spacing of the parallel plate test is measured to simulate the ability of the display panel 10 to resist outward folding and arching after the display panel 10 falls. The experiment verifies that the plate spacing of the two parallel plates is from 4.1mm to 3.5mm before and after the improvement. Before the improvement, when the plate spacing of the two parallel plates is adjusted to 4.1mm, cracks appear in the display panel 10. After the improvement, the plate spacing of the two parallel plates is adjusted to 3.5mm, and cracks appear in the display panel 10. That is, the anti-extrusion ability of the display panel 10 in the outward folded state is improved, and the improvement effect is significant. Therefore, the display panel 10 provided by the present application improves the problem of film cracks caused by stress concentration.
