[0002] A display device includes many precise and sensitive components, which poses relatively high requirements on the packaging performance of the display device.

[0003] The display panel of a display device usually arranges a detection circuit in a jumper area located at the packaging edge to facilitate the detection of packaging performance. Specifically, a ring-shaped wire is arranged at the packaging edge of the display panel. By detecting the electrical parameters of the ring-shaped wire (for example: resistance value, or current change, etc.), it can be determined whether there is a break in the electrical structure within the display panel after packaging is completed, and thus whether the packaging fails.

[0004] However, corrosive media such as water vapor and oxygen will enter the interior of the display panel from the packaging edge of the display panel, for example, reach the drive control area, corrode the sensitive components within the display panel, resulting in packaging failure or defects such as black spots.

[0040] The present application will be described in detail below. Examples of the embodiments of the present application are shown in the drawings, where the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. In addition, if the detailed description of the known technology is unnecessary for showing the features of the present application, it will be omitted. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0041] Those skilled in the art of the present technology can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those of ordinary skill in the art to which the present application belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted in an idealized or overly formal sense unless specifically defined as here.

[0042] Those skilled in the art can understand that, unless specifically stated otherwise, the singular forms "a", "an", "the", and "said" used herein may also include the plural forms. It should be further understood that the term "comprising" used in the specification of this application means the presence of the described features, integers, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, elements, components, and / or their groups. It should be understood that when we say an element is "connected" or "coupled" to another element, it can be directly connected or coupled to other elements, or there may also be intermediate elements. In addition, the "connection" or "coupling" used herein may include wireless connection or wireless coupling. The term "and / or" used herein includes all or any unit and all combinations of one or more of the associated listed items.

[0043] First, several terms related to this application are introduced and explained:

[0044] Main body area: including a drive control area, a display area, and so on.

[0045] The inventors of this application have conducted research and found that a detection circuit is usually arranged in the jumper area located at the edge of the package for facilitating the detection of package performance. The detection circuit can include a multi-layer film structure such as source-drain electrodes and a gate electrode. This multi-layer film structure can ensure the multi-effectiveness, stability, and reliability of the jumper circuit for detecting package failure, and at the same time can also prevent electrostatic injury caused by electrostatic discharge.

[0046] The film layer structure for forming the detection circuit in the jumper area can be that between the gate structure and the source-drain electrode structure at the jumper point is a longitudinal (in the thickness direction of the display panel) stacked structure, and electrical connection is achieved through vias; the film layer structure at non-jumper points is a lateral (perpendicular to the thickness direction of the display panel) side-by-side (or quasi-side-by-side) routing structure of "gate structure - source-drain electrode structure - gate structure". In the jumper area, a planarization layer is required to coat the source-drain electrode layer to avoid corrosion and oxidation of the source-drain electrode layer caused by subsequent processes. However, in the prior art, the planarization layer in the jumper area is a full-coverage design, that is, the planarization layer starts from the edge of the display panel and covers the entire jumper area, and even extends to the main body area of the display panel. This will cause corrosive media such as water vapor and oxygen outside the display panel to invade into the display panel through the planarization layer, contact the sensitive components in the main body area of the display panel, cause electrochemical corrosion to the sensitive components, and lead to package failure or defects such as black spots.

[0047] The display panel and display device provided by this application aim to solve the above technical problems in the prior art.

[0048] The technical solution of this application and how the technical solution of this application solves the above technical problems will be described in detail below with specific embodiments.

[0049] An embodiment of the present application provides a display panel 100. A schematic structural diagram of a first possible implementation manner of the display panel 100 is as follows Figure 1 and Figure 2 shown, including: a substrate 110, a source-drain structure 120, and a planar structure 130 stacked in sequence. The display panel 100 includes: a main area 101 and a jumper area 102 surrounding the periphery of the main area 101.

[0050] A positive projection of at least a part of the planar structure 130 located in the jumper area 102 on the substrate 110 has a first interval 103 from a positive projection of the planar structure 130 located in the main area 101 on the substrate 110, and a positive projection of at least a part of the planar structure 130 located in the jumper area 102 on the substrate 110 has a second interval 104 from a positive projection of the source-drain structure 120 located in the main area 101 on the substrate 110.

[0051] It can be understood that a cover encapsulation layer 150 is covered on the side of the main area 101 and the jumper area 102 away from the substrate 110.

[0052] In this embodiment, a positive projection of at least a part of the planar structure 130 located in the jumper area 102 on the substrate 110 has a first interval 103 from a positive projection of the planar structure 130 located in the main area 101 on the substrate 110, and a positive projection of at least a part of the planar structure 130 located in the jumper area 102 on the substrate 110 has a second interval 104 from a positive projection of the source-drain structure 120 located in the main area 101 on the substrate 110, that is, at least a part of the planar structure 130 in the jumper area 102 forms a partition with the planar structure 130 in the main area 101 and the source-drain structure 120 in the main area 101 respectively, which can effectively cut off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main area 101 of the display panel 100, realize the isolation of water vapor and oxygen, improve the barrier performance of the encapsulation, reduce the probability of black spots occurring in the main area 101 of the display panel 100, and thus can overall improve the yield rate of the display panel 100.

[0053] Optionally, the first interval 103 may coincide with or partially coincide with the second interval 104.

[0054] The inventors of the present application considered that the flat structure 130 in the jumper region 102 mainly coats the source-drain structure 120 in the jumper region 102. It can be seen that the position (or pattern) of the flat structure 130 in the jumper region 102 is associated with the position (or pattern) of the source-drain structure 120 in the jumper region 102. If the position (or pattern) of the source-drain structure 120 in the jumper region 102 can be reasonably defined, it is beneficial to form partitions between the flat structure 130 in the jumper region 102, the flat structure 130 in the main body region 101, and the source-drain structure 120 in the main body region 101 respectively. For this reason, the present application provides the following possible implementation manner for the display panel 100:

[0055] As Figure 2 shown, in the display panel 100 of the embodiment of the present application, there is a third interval 105 between the orthographic projection of at least part of the source-drain structure 120 located in the jumper region 102 on the substrate 110 and the orthographic projection of the source-drain structure 120 located in the main body region 101 on the substrate 110.

[0056] In this embodiment, by defining the position (or pattern) of at least part of the source-drain structure 120 in the jumper region 102, a partition is formed between the at least part of the source-drain structure 120 and the source-drain structure 120 located in the main body region 101, which is beneficial to forming partitions between the flat structure 130 in the jumper region 102, the flat structure 130 in the main body region 101, and the source-drain structure 120 in the main body region 101 respectively. Furthermore, it can effectively cut off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main body region 101 of the display panel 100, realize the isolation of water vapor and oxygen, improve the barrier performance of the package, reduce the probability of black spots occurring in the main body region 101 of the display panel 100, and thus improve the yield rate of the display panel 100 as a whole.

[0057] Optionally, the third interval 105 may coincide with or partially coincide with the second interval 104.

[0058] The inventors of the present application considered that the display panel 100 may also have a gate structure. If the position (or pattern) of part of the gate structure can be reasonably defined, affecting the position (or pattern) of the source-drain structure 120 in the jumper region 102, and indirectly affecting the position (or pattern) of the flat structure 130 in the jumper region 102, it is also beneficial to form partitions between the flat structure 130 in the jumper region 102, the flat structure 130 in the main body region 101, and the source-drain structure 120 in the main body region 101 respectively.

[0059] For this reason, the present application provides the following two possible implementation manners for the display panel 100:

[0060] In a second possible implementation of the display panel 100, as Figure 3 shown, the display panel 100 of the embodiment of the present application further includes a gate structure 140. The orthographic projection of a part of the gate structure 140 on the substrate 110 is located within the third interval 105.

[0061] In this embodiment, the orthographic projection of a part of the gate structure 140 on the substrate 110 is located within the third interval 105, that is, a part of the gate structure 140 can be located between at least part of the source-drain structures 120 in the jumper region 102 and the source-drain structures 120 in the main region 101. In this way, the size of the third interval 105 (that is, the interval distance between at least part of the source-drain structures 120 in the jumper region 102 and the source-drain structures 120 in the main region 101) can be increased, which is beneficial to increasing the sizes of the partitions respectively formed between the planar structure 130 in the jumper region 102 and the planar structure 130 in the main region 101, and between the planar structure 130 in the jumper region 102 and the source-drain structures 120 in the main region 101. Furthermore, the effect of cutting off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main region 101 of the display panel 100 can be strengthened, the isolation of water vapor and oxygen can be realized, the probability of black spots occurring in the main region 101 of the display panel 100 can be reduced, and the packaging yield of the display panel 100 can be improved.

[0062] Optionally, the gate structure 140 located within the third interval 105 is separated from the source-drain structures 120 in the jumper region 102 by an insulating material, and the gate structure 140 located within the third interval 105 is also separated from the source-drain structures 120 in the main region 101 by an insulating material to ensure insulation.

[0063] In a third possible implementation of the display panel 100, as Figure 4 shown, the display panel 100 of the embodiment of the present application further includes a gate structure 140. The orthographic projection of a part of the gate structure 140 on the substrate 110 is located on one side of the orthographic projection of at least part of the source-drain structures 120 on the substrate 110 that is far from the third interval 105.

[0064] In this embodiment, the orthographic projection of the partial gate structure 140 on the substrate 110 is located on the side of the orthographic projection of at least part of the source-drain structure 120 on the substrate 110 that is far from the third spacer 105. This can increase the distance between at least part of the source-drain structure 120 in the jumper region 102 and the edge of the display panel 100, which is beneficial to increasing the distance between the planarization structure 130 in the jumper region 102 and the edge of the display panel 100. Furthermore, it makes it difficult for corrosive media such as water vapor and oxygen outside the display panel 100 to contact the planarization structure 130 in the jumper region 102, that is, it is difficult for the corrosive media to reach the channel that may invade the main region 101 of the display panel 100, thereby strengthening the isolation of water vapor and oxygen, reducing the probability of black spots occurring in the main region 101 of the display panel 100, and improving the packaging yield of the display panel 100.

[0065] Optionally, the gate structure 140 located on the side of the orthographic projection of at least part of the source-drain structure 120 on the substrate 110 that is far from the third spacer 105 is separated from the source-drain structure 120 in the jumper region 102 by an insulating material to ensure insulation.

[0066] Based on the above second possible embodiment and the third possible embodiment of the display panel 100, the inventors of the present application considered that there may be more than one type of gate structure in the display panel 100, or the same type of gate structure may surround the jumper region 102 two or more times. If the positions (or patterns) of two or more gate structures are reasonably defined respectively, or the positions of each loop of the same type of gate structure are reasonably defined respectively, it can affect the position (or pattern) of the source-drain structure 120 in the jumper region 102, and then indirectly affect the position (or pattern) of the planarization structure 130 in the jumper region 102. Then, it is also beneficial to form partitions between the planarization structure 130 in the jumper region 102 and the planarization structure 130 in the main region 101, and between the source-drain structure 120 in the main region 101 respectively. For this reason, taking the gate structure 140 in the display panel 100 including: the first sub-gate structure 141 and the second sub-gate structure 142 as an example, the following three possible implementation manners are provided:

[0067] In the fourth possible embodiment of the display panel 100, as Figure 5 shown, the orthographic projection of the first sub-gate structure 141 of the embodiment of the present application on the substrate 110 and the orthographic projection of the second sub-gate structure 142 on the substrate 110 are both located within the third spacer 105.

[0068] In this embodiment, at least a part of the source-drain structure 120 in the jumper region 102 is inside the first sub-gate structure 141 (on the side closer to the main region 101 of the display panel 100), and at least a part of the source-drain structure 120 in the jumper region 102 is also inside the second sub-gate structure 142. In this way, the size of the third interval 105 (i.e., the interval distance between at least a part of the source-drain structure 120 in the jumper region 102 and the source-drain structure 120 in the main region 101) can be further increased, which is beneficial to further increasing the sizes of the partitions respectively formed between the flat structure 130 in the jumper region 102 and the flat structure 130 in the main region 101, and between the flat structure 130 in the jumper region 102 and the source-drain structure 120 in the main region 101. Furthermore, the effect of cutting off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main region 101 of the display panel 100 can be strengthened, the isolation of water vapor and oxygen can be strengthened, the occurrence probability of black spots in the main region 101 of the display panel 100 can be reduced, and the packaging yield of the display panel 100 can be improved.

[0069] Optionally, the orthographic projection of at least a part of the second sub-gate structure 142 on the substrate 110 is located on the side of the orthographic projection of at least a part of the first sub-gate structure 141 on the substrate 110 that is away from the main region 101 of the display panel 100.

[0070] Optionally, the orthographic projection of at least a part of the second sub-gate structure 142 on the substrate 110 is located on the side of the orthographic projection of at least a part of the first sub-gate structure 141 on the substrate 110 that is closer to the main region 101 of the display panel 100.

[0071] Optionally, the first sub-gate structure 141 and the second sub-gate structure 142 are separated by an insulating material to ensure insulation.

[0072] In the fifth possible implementation manner of the display panel 100, as Figure 6 shown, the orthographic projection of the first sub-gate structure 141 of the embodiment of the present application on the substrate 110 and the orthographic projection of the second sub-gate structure 142 on the substrate 110 are both located on the side of the orthographic projection of at least a part of the source-drain structure 120 on the substrate 110 that is away from the third interval 105.

[0073] In this embodiment, at least a part of the source-drain structure 120 in the jumper region 102 is outside the first sub-gate structure 141 (on the side away from the main region 101 of the display panel 100), and at least a part of the source-drain structure 120 in the jumper region 102 is also outside the second sub-gate structure 142. This can further increase the distance between at least a part of the source-drain structure 120 in the jumper region 102 and the edge of the display panel 100, which is conducive to increasing the distance between the planar structure 130 in the jumper region 102 and the edge of the display panel 100. Furthermore, corrosive media such as water vapor and oxygen outside the display panel 100 are difficult to contact the planar structure 130 in the jumper region 102, that is, the corrosive media are difficult to reach the channels that may invade the main region 101 of the display panel 100, thereby strengthening the isolation of water vapor and oxygen, reducing the probability of black spots in the main region 101 of the display panel 100, and improving the packaging yield of the display panel 100.

[0074] Optionally, the orthographic projection of a part of the second sub-gate structure 142 on the substrate 110 is located on the side of the orthographic projection of a part of the first sub-gate structure 141 on the substrate 110 that is closer to the edge of the display panel 100.

[0075] Optionally, the orthographic projection of a part of the second sub-gate structure 142 on the substrate 110 is located on the side of the orthographic projection of a part of the first sub-gate structure 141 on the substrate 110 that is away from the edge of the display panel 100.

[0076] Optionally, the first sub-gate structure 141 and the second sub-gate structure 142 are separated by an insulating material to ensure insulation.

[0077] In the sixth possible embodiment of the display panel 100, as Figure 7 shown, the orthographic projection of the first sub-gate structure 141 of the embodiment of the present application on the substrate 110 is located within the third interval 105, and the orthographic projection of the second sub-gate structure 142 on the substrate 110 is located on the side of the orthographic projection of at least a part of the source-drain structure 120 on the substrate 110 that is away from the third interval 105.

[0078] In this embodiment, the first sub-gate structure 141 is inside at least a part of the source-drain structure 120 in the jumper region 102 (on the side close to the main region 101 of the display panel 100), which can further increase the size of the third interval 105 (that is, the interval distance between at least a part of the source-drain structure 120 in the jumper region 102 and the source-drain structure 120 in the main region 101), which is conducive to increasing the sizes of the partitions respectively formed between the planar structure 130 in the jumper region 102 and the planar structure 130 in the main region 101, as well as between the planar structure 130 in the jumper region 102 and the source-drain structure 120 in the main region 101. Furthermore, the effect of cutting off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main region 101 of the display panel 100 can be strengthened.

[0079] Moreover, at least a part of the second sub-gate structure 142 is located outside at least a part of the source-drain structure 120 in the jumper region 102 (on the side away from the main region 101 of the display panel 100), which can further increase the distance between at least a part of the source-drain structure 120 in the jumper region 102 and the edge of the display panel 100, facilitating an increase in the distance between the planar structure 130 in the jumper region 102 and the edge of the display panel 100, and further making it difficult for corrosive media such as water vapor and oxygen outside the display panel 100 to contact the planar structure 130 in the jumper region 102.

[0080] That is, in this embodiment, both the channel through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main region 101 of the display panel 100 is strengthened and cut off, and the distance between the planar structure 130 in the jumper region 102 and the edge of the display panel 100 is increased, together strengthening the isolation of water vapor and oxygen, reducing the probability of black spots occurring in the main region 101 of the display panel 100, and improving the packaging yield of the display panel 100.

[0081] The inventors of the present application considered that the same source-drain structure 120 in the display panel 100 may surround two or more circles in the jumper region 102. If the positions of each circle of the same source-drain structure 120 are reasonably defined respectively, it can facilitate the formation of partitions between the planar structure 130 in the jumper region 102, the planar structure 130 in the main region 101, and the source-drain structure 120 in the main region 101. For this reason, the present application provides the following possible implementation manner for the display panel 100:

[0082] In the seventh possible implementation manner of the display panel 100, as Figure 8 shown, in the display panel 100 of the embodiment of the present application, in the jumper region 102, the source-drain structure 120 includes: a first sub-source-drain structure 121 and a second sub-source-drain structure 122.

[0083] There is a fourth interval 106 between the orthographic projection of the first sub-source-drain structure 121 on the substrate 110 and the orthographic projection of the second sub-source-drain structure 122 on the substrate 110. The orthographic projection of the second sub-source-drain structure 122 on the substrate 110 is located on the side of the orthographic projection of the first sub-source-drain structure 121 on the substrate 110 away from the third interval 105.

[0084] In this embodiment, there is a fourth interval 106 between the orthographic projection of the first sub-source-drain structure 121 on the substrate 110 and the orthographic projection of the second sub-source-drain structure 122 on the substrate 110. That is, a partition is formed between the first sub-source-drain structure 121 and the second sub-source-drain structure 122, which is conducive to forming a partition between the flat structures 130 covering the first sub-source-drain structure 121 and the second sub-source-drain structure 122 in the jumper region 102 respectively. Furthermore, it can effectively cut off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main region 101 of the display panel 100, realize the isolation of water vapor and oxygen, reduce the probability of black spots occurring in the main region 101 of the display panel 100, and improve the packaging yield of the display panel 100.

[0085] Based on the above seventh possible embodiment of the display panel 100, the inventors of the present application considered that if the size of the fourth interval 106 can be restricted by the wiring structure, it is conducive to strengthening the formation of partitions between the flat structure 130 in the jumper region 102, the flat structure 130 in the main region 101, and the source-drain structure 120 in the main region 101 respectively. For this purpose, the following possible implementation manner is provided in the embodiment of the present application:

[0086] In the eighth possible embodiment of the display panel 100, as Figure 9 shown, the display panel 100 of the embodiment of the present application further includes a gate structure 140. The orthographic projection of a part of the gate structure 140 on the substrate 110 is located within the fourth interval 106.

[0087] In this embodiment, a part of the gate structure 140 is located within the fourth interval 106, which can further increase the size of the fourth interval 106 (i.e., the interval distance between the first sub-source-drain structure 121 and the second sub-source-drain structure 122 in the jumper region 102), and is conducive to increasing the size of the partition formed between the flat structure 130 covering the first sub-source-drain structure 121 and the flat structure 130 covering the second sub-source-drain structure 122. Furthermore, it can strengthen the effect of cutting off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main region 101 of the display panel 100, strengthen the realization of the isolation of water vapor and oxygen, reduce the probability of black spots occurring in the main region 101 of the display panel 100, and improve the packaging yield of the display panel 100.

[0088] Based on any of the foregoing possible embodiments, optionally, the size of at least one of the first interval 103, the second interval 104, the third interval 105, and the fourth interval 106 is not less than 1 / 4 of the width dimension of the jumper region 102 and not greater than 2 / 3 of the width dimension of the jumper region 102, so as to obtain sufficient ability to isolate water vapor and oxygen and reduce the space waste of the jumper region 102. For example, if the maximum covering width of the flat structure 130 in the jumper region is 60-80 microns, then the width dimension of at least one of the first interval 103, the second interval 104, the third interval 105, and the fourth interval 106 is not less than 20 microns and not greater than 40 microns.

[0089] Based on any of the foregoing possible embodiments, optionally, within the jumper region 102, the orthographic projection of the flat structure 130 on the substrate 110 coincides with the orthographic projection of the source-drain structure 120 on the substrate 110. This is beneficial to improving the space utilization rate of the display panel 100. When the overall size of the display panel 100 is certain, it is beneficial to reduce the size of the jumper region 102, and thus increase the proportion of the main body region 101.

[0090] Based on the same inventive concept, an embodiment of the present application provides a display device, which includes: any display panel 100 provided in the foregoing embodiments.

[0091] The display device can be at least one of a television, a digital photo frame, a mobile phone, a smart watch, a tablet computer, and any other product or component with a display function.

[0092] In this embodiment, since the display device adopts any display panel 100 provided in the foregoing embodiments, the principles and technical effects are referred to the foregoing embodiments and will not be elaborated here.

[0093] Based on the same inventive concept, an embodiment of the present application provides a method for manufacturing a display panel, and the method includes steps S101-S104:

[0094] S101: Fabricate a first conductive layer on one side of the substrate and pattern the first conductive layer to obtain a first gate structure.

[0095] S102: Fabricate a first insulating layer on one side of the substrate and on the first gate structure, and pattern the first insulating layer such that the first insulating layer at the jumper point within the jumper region has a first through hole exposing a part of the first gate structure and also exposes a part of the substrate in the non-jumper point region within the jumper region.

[0096] S103: Fabricate a second conductive layer on the first insulating layer, within the first through-hole, and on the exposed portion of the substrate, and pattern it to obtain a source-drain structure, wherein the orthographic projection of at least a portion of the source-drain structure located within the jumper region on the substrate has a third spacing from the orthographic projection of the source-drain structure located within the main region on the substrate.

[0097] After step S103, the first through-hole is filled with the first conductive layer material, thereby forming a first via, and this first via enables the source-drain structure at the jumper point within the jumper region to be overlapped with the first gate structure below (i.e., prepared by step S101). Moreover, the source-drain structure in the non-jumper point region within the jumper region can run side by side with the first gate structure in the same non-jumper point region.

[0098] S104: Fabricate a planarization layer on the source-drain structure, and pattern the planarization layer to obtain a planarization structure that at least covers the source-drain structure. The orthographic projection of at least a portion of the planarization structure located within the jumper region on the substrate has a first spacing from the orthographic projection of the planarization structure located within the main region on the substrate, and the orthographic projection of at least a portion of the planarization structure located within the jumper region on the substrate has a second spacing from the orthographic projection of the source-drain structure located within the main region on the substrate.

[0099] Applying the embodiments of the present application can at least achieve the following beneficial effects:

[0100] 1. The orthographic projection of at least a portion of the planarization structure 130 located within the jumper region 102 on the substrate 110 has a first spacing 103 from the orthographic projection of the planarization structure 130 located within the main region 101 on the substrate 110, and the orthographic projection of at least a portion of the planarization structure 130 located within the jumper region 102 on the substrate 110 has a second spacing 104 from the orthographic projection of the source-drain structure 120 located within the main region 101 on the substrate 110, that is, at least a portion of the planarization structure 130 within the jumper region 102 forms partitions with the planarization structure 130 within the main region 101 and the source-drain structure 120 within the main region 101 respectively, which can effectively cut off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main region 101 of the display panel 100, achieve the isolation of water vapor and oxygen, improve the barrier performance of the package, reduce the probability of black spots occurring in the main region 101 of the display panel 100, and thus can overall improve the yield rate of the display panel 100.

[0101] 2. In the display panel 100, there is a third interval 105 between the orthographic projection of at least part of the source-drain structure 120 located in the jumper region 102 on the substrate 110 and the orthographic projection of the source-drain structure 120 located in the main body region 101 on the substrate 110. That is, by defining the position (or pattern) of at least part of the source-drain structure 120 in the jumper region 102, a partition can be formed between the at least part of the source-drain structure 120 and the source-drain structure 120 located in the main body region 101, which is conducive to forming partitions between the flat structure 130 in the jumper region 102 and the flat structure 130 in the main body region 101, and between the source-drain structure 120 in the main body region 101 respectively. Furthermore, the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main body region 101 of the display panel 100 can be effectively cut off, realizing the isolation of water vapor and oxygen, improving the barrier performance of the package, reducing the probability of black spots occurring in the main body region 101 of the display panel 100, and thus improving the overall yield of the display panel 100.

[0102] 3. The orthographic projection of part of the gate structure 140 on the substrate 110 is located within the third interval 105, that is, part of the gate structure 140 can be located between at least part of the source-drain structure 120 in the jumper region 102 and the source-drain structure 120 in the main body region 101. In this way, the size of the third interval 105 (i.e., the interval distance between at least part of the source-drain structure 120 in the jumper region 102 and the source-drain structure 120 in the main body region 101) can be increased, which is conducive to increasing the sizes of the partitions respectively formed between the flat structure 130 in the jumper region 102 and the flat structure 130 in the main body region 101, and between the source-drain structure 120 in the main body region 101. Furthermore, the effect of cutting off the channels through which corrosive media such as water vapor and oxygen outside the display panel 100 may invade the main body region 101 of the display panel 100 can be strengthened, the isolation of water vapor and oxygen can be strengthened, the probability of black spots occurring in the main body region 101 of the display panel 100 can be reduced, and the package yield of the display panel 100 can be improved.

[0103] 4. The orthographic projection of part of the gate structure 140 on the substrate 110 is located on the side of the orthographic projection of at least part of the source-drain structure 120 on the substrate 110 that is far from the third interval 105. In this way, the distance between at least part of the source-drain structure 120 in the jumper region 102 and the edge of the display panel 100 can be increased, which is conducive to increasing the distance between the flat structure 130 in the jumper region 102 and the edge of the display panel 100. Furthermore, corrosive media such as water vapor and oxygen outside the display panel 100 are difficult to contact the flat structure 130 in the jumper region 102, that is, the corrosive media are difficult to reach the channels that may invade the main body region 101 of the display panel 100, thus strengthening the realization of the isolation of water vapor and oxygen, reducing the probability of black spots occurring in the main body region 101 of the display panel 100, and improving the package yield of the display panel 100.

[0104] 5. Reasonably limit the positions (or patterns) of two or more gate structures respectively, or reasonably limit the positions of each turn of the same gate structure respectively, which affects the positions (or patterns) of the source-drain structures 120 in the jumper region 102, and thus indirectly affects the positions (or patterns) of the flat structures 130 in the jumper region 102. This can also facilitate the formation of partitions respectively between the flat structures 130 in the jumper region 102, the flat structures 130 in the main body region 101, and the source-drain structures 120 in the main body region 101.

[0105] 6. Reasonably limit the positions of each turn of the same source-drain structure 120 respectively, that is, a fourth interval 106 is formed between the orthographic projection of the first sub-source-drain structure 121 on the substrate 110 and the orthographic projection of the second sub-source-drain structure 122 on the substrate 110. Then it can facilitate the formation of partitions respectively between the flat structures 130 in the jumper region 102, the flat structures 130 in the main body region 101, and the source-drain structures 120 in the main body region 101.

[0106] 7. The orthographic projection of a part of the gate structure 140 on the substrate 110 is located within the fourth interval 106. By restricting the size of the fourth interval 106 through the routing structure, it can facilitate strengthening the formation of partitions respectively between the flat structures 130 in the jumper region 102, the flat structures 130 in the main body region 101, and the source-drain structures 120 in the main body region 101.
