[0052] In the display panel, the display panel includes light-emitting units 333 and an encapsulation layer 370 for encapsulating the light-emitting units 333. The encapsulation layer 370 typically includes a first inorganic encapsulation layer 370, an organic encapsulation layer 370, and a second inorganic encapsulation layer 370. The organic encapsulation layer 370 is typically located within the area enclosed by the display panel's dam. In related technologies, there are instances where the organic encapsulation layer 370 overflows partially outside the dam.

[0053] To better understand this application, the following will be combined with... Figures 1 to 6 The display panel and display device according to embodiments of this application will be described in detail.

[0054] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of this application; Figure 2 yes Figure 1 A sectional view.

[0055] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of this application provides a display panel, the display panel including a display area AA and a non-display area NA located on at least one side of the display area AA, the display panel including: a substrate 100; a first conductive layer 210 disposed on the substrate 100, the first conductive layer 210 including a first conductive portion 211 located in the non-display area NA; a first organic insulating layer 310 disposed on the side of the first conductive layer 210 facing away from the substrate 100, the first organic insulating layer 310 having a first via 311 located in the non-display area NA; and a second conductive layer 220 disposed on the substrate 100. The system includes a second signal line 221 located in the non-display area NA, which is electrically connected to the first via 311 and the first conductive portion 211; and a touch component 400 disposed on the side of the second conductive layer 220 away from the substrate 100. The touch component 400 includes a touch insulating layer 410 extending from the display area AA to the non-display area NA. The touch insulating layer 410 has a clearance opening 413, wherein the orthographic projection of the first via 311 on the substrate 100 and the orthographic projection of the clearance opening 413 on the substrate 100 at least partially overlap.

[0056] In the display panel provided in the embodiments of this application, the display panel includes a display area AA and a non-display area NA. The display area AA is used to realize the display function of the display panel, and the non-display area NA can be used to set signal lines and other devices. The display panel includes a substrate 100, a first conductive layer 210, a first organic insulating layer 310, a second conductive layer 220, and a touch assembly 400. The first conductive portion 211 of the first conductive layer 210 is electrically connected to the second conductive portion 211 of the second conductive layer 220 via a first via 311 on the first organic insulating layer 310. The material of the first organic insulating layer 310 includes organic materials. The first organic insulating layer 310 is prone to generating impurities such as moisture when exposed to high temperatures. The touch insulating layer 410 of the touch assembly 400 has a clearance opening 413. The orthographic projection of the first via 311 on the substrate 100 and the orthographic projection of the clearance opening 413 on the substrate 100 at least partially overlap, so that the impurities such as moisture generated in the area where the first via 311 is located can quickly overflow from the clearance opening 413, improving the yield of moisture that accumulates near the first via 311 and affects the first conductive portion 211 and / or the second conductive portion 211. Therefore, by opening a clearance opening 413 on the touch insulating layer 410, the yield of the first conductive part 211 and the second conductive part 211 can be improved, thereby enhancing the overall process performance of the display panel.

[0057] There are several ways to set the non-display area NA. For example, the non-display area NA can be arranged in a ring around the display area AA. Alternatively, the non-display area NA can be set on one or both sides of the display area AA in the first direction X or the second direction Y.

[0058] There are various ways to configure the substrate 100. For example, the substrate 100 may include a substrate, a buffer layer, etc., and the buffer layer may be disposed on the side of the substrate away from the first conductive layer 210. The buffer layer may include foam, steel plate, etc. The substrate 100 may also include only a substrate, which may be a flexible substrate or a rigid substrate.

[0059] Optionally, other conductive layers may be disposed between the substrate 100 and the first conductive layer 210.

[0060] In some alternative embodiments, the first via 311 is projected onto the substrate 100 in the orthographic projection of the relief opening 413 onto the substrate 100.

[0061] In these alternative embodiments, the clearance opening 413 and the first via 311 are completely correspondingly set, so that impurities such as water vapor generated in the area where the first via 311 is located can be discharged from the clearance opening 413 more quickly, which can better improve the process performance of the display panel.

[0062] Optional, such as Figures 1 to 3 As shown, Figure 3 yes Figure 1 The enlarged schematic diagram of the central non-display area NA shows that the clearance opening 413 is a closed ring at the edge of the orthogonal projection of the substrate 100, and part of the touch insulating layer 410 is located on the side of the clearance opening 413 away from the display area AA. That is to say, the clearance opening 413 is not formed by the edge of the touch insulating layer 410 receding inward toward the display area AA, but rather the clearance opening 413 penetrates the internal area of ​​the touch insulating layer 410. The sides of the clearance opening 413 facing and away from the display area AA are both provided with touch insulating layers 410, and the distribution area of ​​the touch insulating layer 410 is relatively large, which can provide better protection to the substrate-side front film layer.

[0063] There are several ways to set the touch insulating layer 410, for example, such as Figure 2 As shown, the touch insulating layer 410 includes a touch organic layer 412 and a touch inorganic layer 411. The material of the touch organic layer 412 may include an organic insulating material, and the material of the touch inorganic layer 411 may include an inorganic insulating material. The touch inorganic layer 411 has better sealing performance. In some optional embodiments, a clearance opening 413 is provided to pass through the touch inorganic layer 411.

[0064] In these alternative embodiments, the density of the touch inorganic layer 411 is better. By placing the clearance opening 413 in the touch inorganic layer 411, the problem of impurities such as moisture being unable to escape from the touch inorganic layer 411 can be better resolved, and the process performance of the display panel can be better improved.

[0065] There are several ways to position the touch-sensitive inorganic layer 411 and the touch-sensitive organic layer 412. For example, the touch-sensitive inorganic layer 411 can be located on the side of the touch-sensitive organic layer 412 facing the substrate 100, or the touch-sensitive organic layer 412 can cover the touch-sensitive inorganic layer 411. Alternatively, the touch-sensitive organic layer 412 can cover the side surface of the touch-sensitive inorganic layer 411, thus mitigating the impact of impurities such as metal materials accumulated at the location of the side surface of the touch-sensitive inorganic layer 411 on other components within the display panel.

[0066] Optionally, the touch inorganic layer 411 includes a bottom surface facing the substrate 100 and a top surface facing away from the substrate 100, with a side surface connected between the top and bottom surfaces. The material of the touch inorganic layer 411 includes inorganic materials. During the fabrication process of the touch inorganic layer 411, the angle between the side surface and the bottom surface is relatively large, and impurities such as metal particles are easily deposited at the location of the side surface. These particles can affect other film layers. The touch organic layer 412 covers the side surface of the touch inorganic layer 411, so that the touch organic layer 412 can also cover these impurities such as metal particles, thereby improving the impact of these impurities on other film layers in the display panel.

[0067] Optionally, the touch inorganic layer 411 can be an integral structure, or the touch inorganic layer 411 can include a first sub-layer 411a and a second sub-layer 411b, where the first sub-layer 411a can be a touch substrate layer and the second sub-layer 411b can be an insulating layer between touch electrodes.

[0068] like Figure 4 As shown, the touch assembly 400 further includes a touch conductive layer 440, which includes a touch electrode layer 441 and a touch bridge layer 442. The touch electrode layer 441 includes a plurality of touch electrodes, and the touch bridge layer 442 includes a bridge portion, through which at least two touch electrodes are electrically connected to each other. A first sublayer 411a is located on the side of the touch conductive layer 440 facing the substrate 100, and a second sublayer 411b may be located between the touch electrode layer 441 and the touch bridge layer 442.

[0069] In some other alternative embodiments, such as Figure 5 As shown, the clearance opening 413 can also penetrate the touch organic layer 412, so that impurities such as water vapor can continue to overflow from the clearance opening 413 on the touch organic layer 412, thereby better improving the problem of water vapor accumulation.

[0070] In some alternative embodiments, such as Figures 1 to 5 As shown, the array substrate 100 further includes: a first inorganic insulating layer 510 located on the side of the first conductive layer 210 facing the substrate 100, the first inorganic insulating layer including a through-hole 511; a third conductive layer 230 located between the first inorganic insulating layer 510 and the substrate 100, the third conductive layer 230 including a third signal line 231, the third signal line 231 extending from the display area AA to the non-display area NA, the third signal line 231 and the first conductive portion 211 being electrically connected via the second through-hole 511, wherein the first inorganic insulating layer 510 includes a first edge L1 located in the non-display area NA, the touch inorganic layer 411 includes a second edge L2 located in the non-display area NA, the clearance opening 413 is located on the side of the second edge L2 facing the display area AA, and the orthographic projection of the second edge L2 on the substrate 100 is located on the side of the orthographic projection of the first edge L1 on the substrate 100 away from the display area AA. Figure 3 The dotted lines in the middle indicate the edge positions of each film layer.

[0071] In these optional embodiments, a first inorganic insulating layer 510 and a third conductive layer 230 are further disposed on the substrate 100. The third conductive layer 230 is located on the side of the first conductive layer 210 facing the substrate 100. The third signal line 231 of the third conductive layer 230 is electrically connected to the first conductive portion 211 of the first conductive layer 210, so that the third signal line 231 can be electrically connected through the first conductive portion 211 and the second signal line 221 of the second conductive layer 220. The first inorganic insulating layer 510 is disposed between the third conductive layer 230 and the first conductive layer 210, which can improve the short-circuit connection problem between the third conductive layer 230 and the first conductive layer 210. In addition, the second edge L2 of the touch inorganic layer 411 is located on the side of the first edge L1 of the first inorganic insulating layer 510 away from the display area AA, so that the distribution area of ​​the touch inorganic layer 411 is larger and the touch inorganic layer 411 can provide better protection.

[0072] Optionally, the orthographic projection of the second via 511 onto the substrate 100 and the orthographic projection of the clearance opening 413 onto the substrate 100 at least partially overlap. For example, the orthographic projection of the second via 511 onto the substrate 100 lies within the orthographic projection of the clearance opening 413 onto the substrate 100. This results in a larger distribution area of ​​the clearance opening 413, which can better improve the problem of moisture accumulation.

[0073] In some alternative embodiments, such as Figure 3 As shown, the second edge L2 and the first edge L1 are equally spaced in the orthographic projection of the substrate 100.

[0074] In these optional embodiments, the second edge L2 and the first edge L1 have the same shape, and the second edge L2 and the first edge L1 are equally spaced, which can improve the stress concentration problem of the second edge L2, improve the problem of easy cracking in the touch inorganic layer 411, and improve the process performance of the display panel.

[0075] There are various shapes for the extension paths of the first edge L1 and the second edge L2. For example, the first edge L1 and the second edge L2 can extend along curved paths. In some alternative embodiments, the first edge L1 and the second edge L2 can extend along straight paths, making it less likely for stress concentration to occur near the first edge L1 and the second edge L2.

[0076] Optional, such as Figure 2 and Figure 3As shown, the display panel is a flexible display panel. A portion of the non-display area NA can be bent to the non-display side of the display panel to reduce the distribution area of ​​the non-display area NA on the display side and increase the screen-to-body ratio. For example, the non-display area NA includes a transition area NA1 and a bending area NA2. The transition area NA1 is located between the bending area NA2 and the display area AA. A portion of the non-display area NA can be bent to the non-display side of the display panel through the bending area NA2.

[0077] In some optional embodiments, the first edge L1 is located at the boundary between the bending region NA2 and the transition region NA1, and the second edge L2 is located within the bending region NA2. That is, the position of the first edge L1 defines the boundary between the bending region NA2 and the transition region NA1, and the second edge L2 is located within the bending region NA2. The touch-sensitive inorganic layer 411 extends into the bending region NA2, which increases the distribution area of ​​the touch-sensitive inorganic layer 411 and enhances its protective function.

[0078] There are several ways to set the third conductive layer 230. For example, the third conductive layer 230 can be set as a single film layer, so that the array substrate 100 has a simpler structure.

[0079] In some other alternative embodiments, such as Figure 2 and Figure 3 As shown, the third conductive layer 230 includes a first sub-conductive layer 230a and a second sub-conductive layer 230b. A second inorganic insulating layer 520 is disposed between the first sub-conductive layer 230a and the second sub-conductive layer 230b. The second inorganic insulating layer 520 is flush with the edge of the non-display area NA and the first edge L1.

[0080] In these optional embodiments, the third conductive layer 230 includes two conductive material layers: a first sub-conductive layer 230a and a second sub-conductive layer 230b. To improve the short-circuit problem between the first sub-conductive layer 230a and the second sub-conductive layer 230b, a second inorganic insulating layer 520 is disposed between the first sub-conductive layer 230a and the second sub-conductive layer 230b. The edge of the second inorganic insulating layer 520 is flush with the edge of the non-display area NA and the first edge L1. The inorganic layer has a small thickness, and the fact that the edge of the second inorganic insulating layer 520 is flush with the first edge L1 simplifies the display film structure. It also facilitates the use of the same mask to prepare the first inorganic insulating layer 510 and the second inorganic insulating layer 520.

[0081] Optionally, when the third conductive layer 230 includes a first sub-conductive layer 230a and a second sub-conductive layer 230b, the third signal line 231 may include a first sub-signal line 231a located in the first sub-conductive layer 230a and a second sub-signal line 231b located in the second sub-conductive layer 230b. At least one of the first sub-signal line 231a and the second sub-signal line 231b is connected to the first conductive portion 211 via. For example, both the first sub-signal line 231a and the second sub-signal line 231b can be connected to the first conductive portion 211 via. For example, the first sub-signal line 231a and the second sub-signal line 231b can be connected to different first conductive portion 211 vias, so that both the first sub-signal line 231a and the second sub-signal line 231b can be electrically connected to the second signal line 221 through the first conductive portion 211. Alternatively, the first sub-signal line 231a and the second sub-signal line 231b can be connected to the same first conductive part 211 via, so that the first sub-signal line 231a and the second sub-signal line 231b can be electrically connected to each other through the first conductive part 211.

[0082] In some alternative embodiments, please continue to refer to Figure 1 and Figure 2 The display panel also includes a supporting insulating layer 540 located between the third conductive layer 230 and the substrate 100. The supporting insulating layer 540 includes a third edge L3 located in the non-display area NA. The orthographic projection of the third edge L3 on the substrate 100 is located on the side of the orthographic projection of the second edge L2 on the substrate 100 that is away from the display area AA.

[0083] In these optional embodiments, a supporting insulating layer 540 is disposed between the third conductive layer 230 and the substrate 100, which can provide support to the third conductive layer 230 and other film layers. The supporting insulating layer 540 has a third edge L3 located in the non-display area NA, which is located on the side of the second edge L2 away from the display area AA, so that the distribution area of ​​the supporting insulating layer 540 is larger and the supporting insulating layer 540 can provide better support.

[0084] There are various ways to configure the supporting insulating layer 540. For example, the supporting insulating layer 540 may include at least one of a supporting buffer layer and an insulating dielectric film layer. This allows the supporting insulating layer 540 to have good supporting performance and dielectric constant.

[0085] Optionally, when the third conductive layer 230 includes a first sub-conductive layer 230a and a second sub-conductive layer 230b, and the first sub-conductive layer 230a and the second sub-conductive layer 230b are stacked in a direction away from the substrate 100, the supporting insulating layer 540 can be disposed between the first sub-conductive layer 230a and the substrate 100. This allows the supporting insulating layer 540 to provide support to the first sub-conductive layer 230a and the second sub-conductive layer 230b.

[0086] Optional, such as Figure 4 As shown, the display panel also includes an active layer P, which is provided with a semiconductor section. The active layer P can be disposed between the first sub-conductive layer 230a and the supporting insulating layer 540.

[0087] Optional, such as Figures 2 to 4 As shown, the display panel also includes a third inorganic insulating layer 530, which is located between the third conductive layer 230 and the supporting insulating layer 540. The third inorganic insulating layer 530 is flush with the edge of the non-display area NA and the first edge L1. The third inorganic insulating layer 530 can be disposed, for example, between the first sub-conductive layer 230a and the active layer P to improve the short-circuit connection problem between the active layer P and the first sub-conductive layer 230a.

[0088] In these alternative embodiments, the third inorganic insulating layer 530 is flush with the edge of the non-display area NA and the first edge L1, that is, the first inorganic insulating layer 510, the second inorganic insulating layer 520 and the third inorganic insulating layer 530 are flush, which can simplify the film layer structure of the display panel.

[0089] Optionally, the minimum distance H1 between the orthographic projection of the third edge L3 onto the substrate 100 and the orthographic projection of the first edge L1 onto the substrate 100 is 10 μm to 20 μm. For example, the minimum distance between the third edge L3 and the first edge L1 onto the substrate 100 can be 10 μm, 12.5 μm, 15 μm, 18.2 μm, 20 μm, etc. This improves the situation where the distribution area of ​​the support buffer layer is too small due to the small distance H1 between the third edge L3 and the first edge L1, thus affecting the supporting function of the support buffer layer. It also improves the situation where the distribution area of ​​the first inorganic insulating layer 510 is too small due to the large distance between the third edge L3 and the first edge L1, thus affecting its insulating performance.

[0090] Optional, such as Figure 2 and Figure 4As shown, a first metal layer M1, a second metal layer M2, and a third metal layer M3 are sequentially stacked on one side of the substrate 100. An insulating layer is disposed between adjacent metal layers. For example, a pixel driving circuit is disposed on the substrate 100, and the pixel driving circuit includes a transistor and a storage capacitor. The transistor includes a semiconductor, a gate, a source, and a drain. The storage capacitor includes a first electrode and a second electrode. As an example, the gate and the first electrode can be located in the first metal layer M1, the second electrode can be located in the second metal layer M2, and the source and drain can be located in the third metal layer M3. The first sub-conductive layer 230a can be the first metal layer M1, the second sub-conductive layer 230b can be the second metal layer M2, and the first conductive layer 210 can be the third metal layer M3. When the first sub-conductive layer 230a is the first metal layer M1, the third inorganic insulating layer 530 between the first sub-conductive layer 230a and the active layer P can be an inter-gate insulating layer. The insulating layer between the first sub-conductive layer 230a and the second sub-conductive layer 230b can be a capacitor dielectric insulating layer.

[0091] In some alternative embodiments, such as Figure 2 and Figure 3 As shown, the edge of the touch-sensitive organic insulating layer located in the non-display area NA is projected onto the substrate 100 on the side of the second edge L2 projected onto the substrate 100 away from the display area AA. Optionally, the edge of the touch-sensitive organic insulating layer located in the non-display area NA is a fourth edge L4. That is, the projection of the fourth edge L4 onto the substrate 100 is projected onto the side of the second edge L2 projected onto the substrate 100 away from the display area AA.

[0092] In these optional embodiments, the edge of the touch organic layer 412 is located on the side of the second edge L2 away from the display area AA, which can increase the distribution area of ​​the touch organic layer 412 and ensure that the touch organic layer 412 can completely cover the touch inorganic layer 411, thereby better improving the impact of metal residue on the side surface of the touch inorganic layer 411 on other film layers.

[0093] Optionally, the touch-sensitive organic insulating layer is positioned at equal intervals between the edge of the non-display area NA and the orthographic projection of the first edge L1 on the substrate 100.

[0094] In these alternative embodiments, the edges of the touch organic layer 412 and the first edge L1 are equally spaced, which can better improve the problem of stress concentration at the edge of the film layer.

[0095] Optionally, the edge of the touch-sensitive organic insulating layer located in the non-display area NA is provided at equal intervals on the orthographic projection of the substrate 100 and the second edge L2. For example, the edge of the touch-sensitive organic insulating layer located in the non-display area NA is formed along a straight line on the orthographic projection of the substrate 100 and the second edge L2, which can better improve the problem of stress concentration at the edge of the film layer.

[0096] Optionally, the edge of the touch-sensitive organic insulating layer located in the non-display area NA is projected onto the substrate 100 on the side opposite to the display area AA in the projection of the third edge L3 onto the substrate 100. This increases the distribution area of ​​the touch-sensitive organic insulating layer, allowing it to better cover the side surface of the touch-sensitive inorganic layer 411. Furthermore, the distribution area of ​​the touch-sensitive organic insulating layer is larger than that of the first inorganic insulating layer 510, the second inorganic insulating layer 520, the third inorganic insulating layer 530, and the support buffer layer, providing better protection.

[0097] Optionally, the distance H2 between the edge of the touch-sensitive organic insulating layer located in the non-display area NA and the orthographic projection of the third edge L3 onto the substrate 100 is 11 μm to 20 μm. For example, the distance H2 between the edge of the touch-sensitive organic insulating layer located in the non-display area NA and the orthographic projection of the third edge L3 on the substrate 100 is 11μm, 15μm, 16.5μm, 18μm, 20μm, etc., to improve the situation where the distance between the edge of the touch-sensitive organic insulating layer located in the non-display area NA and the orthographic projection of the third edge L3 on the substrate 100 is too small, causing the touch-sensitive organic insulating layer and the third edge L3 to be flush or close, resulting in stress concentration and affecting the film yield; it can also improve the situation where the distance between the edge of the touch-sensitive organic insulating layer located in the non-display area NA and the orthographic projection of the third edge L3 on the substrate 100 is too large, resulting in an excessively large distribution area of ​​the touch-sensitive organic insulating layer penetrating into the bending area NA2, affecting the bending performance of the bending area NA2.

[0098] Optionally, the touch-sensitive organic insulating layer is located on the side of the touch-sensitive inorganic insulating layer opposite to the substrate 100, and the touch-sensitive organic insulating layer covers the side surface of the touch-sensitive inorganic insulating layer in the non-display area NA. This is to mitigate the impact of residual metal particles and other impurities near the side surface on the manufacturing yield of the display panel.

[0099] In some alternative embodiments, such as Figure 3As shown, the touch component 400 further includes a touch signal line 420, which is located on at least a portion of the touch inorganic layer 411 on the side opposite to the substrate 100. A third via 450 is provided on at least a portion of the touch inorganic layer 411. The display panel further includes a touch control signal line 430, which is connected to the touch signal line 420 via the third via 450. The projected area of ​​the third via 450 on the substrate 100 is smaller than the projected area of ​​the clearance opening 413 on the substrate 100. Optionally, when the touch inorganic layer 411 includes a first sub-layer 411a and a second sub-layer 411b, the touch signal line 420 may be located in the touch electrode layer 441, and the third via 450 may be configured to penetrate at least the first sub-layer 411a; or, the touch signal line 420 may be located in the touch bridge layer 442, and the third via 450 may be configured to penetrate at least the first sub-layer 411a and the second sub-layer 411b.

[0100] In these optional embodiments, the touch component 400 further includes a touch signal line 420, which is electrically connected to the touch control signal line 430 of the non-display area NA via a third via 450 on the touch inorganic layer 411. The projected area of ​​the third via 450 on the substrate 100 is smaller than the projected area of ​​the clearance opening 413 on the substrate 100, resulting in a larger distribution area of ​​the clearance opening 413, which can better improve the problem of water vapor accumulation.

[0101] Optional, such as Figure 4 As shown, the display panel also includes a second organic insulating layer 320 and a pixel definition layer 330 sequentially distributed on the side of the second conductive layer 220 away from the substrate 100, and a fifth via penetrating the second organic insulating layer 320 and the pixel definition layer 330. The fifth via is connected to the third via 450, and the touch signal line 420 and the touch control signal line 430 are interconnected via the third via 450 and the fifth via.

[0102] In these optional embodiments, the second conductive layer 220 is provided with a second organic insulating layer 320 and a pixel definition layer 330. The touch signal line 420 is located on the side of the second organic insulating layer 320 and the pixel definition layer 330 facing away from the substrate 100. A fifth via is formed on the second organic insulating layer 320 and the pixel definition layer 330, which communicates with the third via 450, so that the touch signal line 420 and the touch control signal line 430 can be interconnected through the third via 450 and the fifth via.

[0103] Optionally, the display panel further includes a support pillar material layer 340, which is located on the side of the pixel definition layer 330 facing away from the substrate 100. A fifth via also extends through the support pillar material layer 340 to facilitate electrical connection between the touch signal line 420 and the touch control signal line 430.

[0104] There are various ways to position the touch control signal line 430. For example, the touch control signal line 430 can be located in the second conductive layer 220, so that the touch control signal line 430 and the second signal line 221 can be arranged in the same layer. The touch control signal line 430 and the second signal line 221 can be formed in the same process step, which can simplify the manufacturing process of the display panel.

[0105] In some alternative embodiments, such as Figure 3 As shown, the clearance opening 413 has a first side on one side of the display area AA when projected onto the substrate 100, and the third via 450 has a second side on one side of the display area AA when projected onto the substrate 100. The non-display area NA includes a transition area NA1 and a bending area NA2. The transition area NA1 is located between the bending area NA2 and the display area AA. The clearance opening 413 and the third via 450 are both located in the transition area NA1. The minimum distance H3 between the first side and the bending area NA2 is greater than the minimum distance H4 between the second side and the bending area NA2. Figure 3 The location of the clearance opening 413 is indicated by a dotted-line box.

[0106] In these alternative embodiments, when the display panel has a transition area NA1 and a bending area NA2, the clearance opening 413 and the third via 450 are both located in the transition area NA1, and the minimum distance H3 between the first side and the bending area NA2 is greater than the minimum distance H4 between the second side and the bending area NA2, so that the first side and the second side are not concentrated, thereby improving the problem of excessive stress in the inner film layer of the bending area NA2.

[0107] Optionally, the distribution area of ​​the clearance opening 413 is usually larger than the distribution area of ​​the third through hole 450, and the minimum distance H3 between the first side and the bending area NA2 is greater than the minimum distance H4 between the second side and the bending area NA2, so that the distance between the clearance opening 413 with the larger distribution area and the bending area NA2 is greater, which can better improve the bending performance of the bending area NA2.

[0108] There are several ways to set the correspondence between the first through hole 311 and the clearance opening 413. For example, multiple first through holes 311 can correspond to the same clearance opening 413 or multiple clearance openings 413. For example, the first through holes 311 and clearance openings 413 can be set in a one-to-one correspondence.

[0109] In some other alternative embodiments, such as Figure 3 As shown, the same second signal line 221 is connected via two or more first vias 311 and first conductive portion 211 vias; the orthographic projections of the plurality of first vias 311 corresponding to the same second signal line 221 on the substrate 100 and the orthographic projections of the same clearance opening 413 on the substrate 100 at least partially overlap.

[0110] In these optional embodiments, the same second signal line 221 is electrically connected to the first conductive portion 211 via two or more first vias 311, which can improve the connection yield between the second signal line 221 and the first conductive portion 211. The projections of the plurality of first vias 311 corresponding to the same second signal line 221 onto the substrate 100 and the projections of the same clearance opening 413 onto the substrate 100 at least partially overlap. The plurality of first vias 311 corresponding to the same second signal line 221 are generally spaced apart along the extension direction of the second signal line 221. The plurality of first vias 311 corresponding to the same second signal line 221 and the same clearance opening 413 are correspondingly arranged, which can ensure that the opening area of ​​the clearance opening 413 is small and that the same clearance opening 413 can be associated with multiple first vias 311, simplifying the arrangement pattern of the clearance opening 413.

[0111] Optionally, the orthographic projections of multiple first vias 311 on the same second signal line 221 onto the substrate 100 are located within the orthographic projection of the same clearance opening 413 onto the substrate 100. This allows impurities such as moisture generated at the location of the multiple first vias 311 to escape as quickly as possible through the clearance opening 413.

[0112] The second signal line 221 is connected to the first via 311 via the first via 311 and the first conductive part 211 via the first conductive part 211.

[0113] In some alternative embodiments, such as Figure 6As shown, a plurality of second signal lines 221 are arranged side-by-side at intervals along a first direction X, and the second signal lines 221 extend along a second direction Y, wherein the first direction X and the second direction Y intersect; the projections of the first vias 311 corresponding to the plurality of second signal lines 221 on the substrate 100 and the projections of the same clearance opening 413 on the substrate 100 at least partially overlap. The corresponding arrangement of the first vias 311 and the same clearance opening 413 for the plurality of second signal lines 221 further simplifies the arrangement of the clearance opening 413. Optionally, both the first direction X and the second direction Y are perpendicular to the thickness direction Z of the display panel.

[0114] Optional, such as Figure 4 As shown, the pixel definition layer 330 includes a pixel defining portion 331 and a pixel opening 332. A first electrode layer 350 is disposed on the side of the second organic insulating layer 320 away from the substrate. The first electrode layer 350 includes a plurality of first electrodes 351 distributed in an array. A portion of the first electrode 351 is exposed through the pixel opening 332, and another portion of the first electrode 351 may be located between the pixel defining portion 331 and the second organic insulating layer 320. The pixel opening 332 is used to accommodate the light-emitting unit 333.

[0115] Optionally, the display panel further includes a second electrode layer 360, which includes a second electrode 361 located on the side of each light-emitting unit 333 facing away from the substrate 100. The second electrode 361 and the first electrode 351 can interact to drive the light-emitting unit 333 to emit light. Optionally, the display panel further includes an encapsulation layer 370 located on the side of the second electrode layer 360 facing away from the substrate 100. The touch component 400 may be located on the side of the encapsulation layer 370 facing away from the substrate 100. The encapsulation layer 370 may include stacked inorganic layers, organic layers, and inorganic layers.

[0116] like Figures 1 to 6As shown, an embodiment of the first aspect of this application also provides a display panel, the display panel including a display area AA and a non-display area NA, the non-display area NA including a transition area NA1 and a bending area NA2, the transition area NA1 being located between the display area AA and the bending area NA2, the display panel including: a substrate 100; a first inorganic insulating layer 510 disposed on one side of the substrate 100, the first inorganic insulating layer 510 including a first edge L1 located at the boundary between the bending area NA2 and the transition area NA1. A first conductive layer 210 is disposed on the substrate 100, and the first conductive layer 210 includes a first conductive portion 211 located in the non-display area NA; a first organic insulating layer 310 is disposed on the side of the first conductive layer 210 away from the substrate 100, and a first via 311 located in the non-display area NA is disposed on the first organic insulating layer 310; a second conductive layer 220 is disposed on the substrate 100 and includes a second signal line 221 located in the non-display area NA, and the second signal line 221 is electrically connected to the first conductive portion 211 via the first via 311. A touch component 400 is disposed on the side of the second conductive layer 220 away from the substrate 100. The touch component 400 includes a touch inorganic layer 411 and a touch organic layer 412. The touch inorganic layer 411 includes a second edge L2 located in the non-display area NA. The orthographic projection of the second edge L2 on the substrate 100 is located on the side of the orthographic projection of the first edge L1 on the substrate 100 away from the display area AA. The edge of the touch organic insulating layer located in the non-display area NA is located on the side of the orthographic projection of the second edge L2 on the substrate 100 away from the display area AA.

[0117] In the display panel provided in this embodiment, the display panel includes a display area AA and a non-display area NA. The display area AA is used to realize the display function of the display panel, and the non-display area NA can be used to set signal lines and other devices. The display panel includes a substrate 100, a first conductive layer 210, a first organic insulating layer 310, a second conductive layer 220, and a touch component 400.

The touch component 400 includes a touch inorganic layer 411 and a touch organic layer 412. The second edge L2 of the touch inorganic layer 411 is located on the side of the first edge L1 of the first inorganic insulating layer 410 away from the display area AA, so that the distribution area of ​​the touch inorganic layer 411 is larger and the touch inorganic layer 411 can provide better protection. The edge of the touch organic layer 412 is located on the side of the second edge L2 away from the display area AA, which can increase the distribution area of ​​the touch organic layer 412 and ensure that the touch organic layer 412 can completely cover the touch inorganic layer 411, better improve the influence of metal residue on the side surface of the touch inorganic layer 411 on other film layers, and thus improve the overall process performance of the display panel.

[0119] For example, the second edge L2 and the first edge L1 are equally spaced in the orthographic projection of the substrate 100.

[0120] The second aspect of this application also provides a display device, including the display panel of any of the first aspect embodiments described above. Since the display device provided in the second aspect of this application includes the display panel of any of the first aspect embodiments described above, it has the beneficial effects of the display panel of any of the first aspect embodiments described above, which will not be elaborated further here.
