[0040] The orientation terms appearing in the following description are all in the directions shown in the figures and do not limit the specific structure of the embodiments of the present application. In the description of the present application, unless there are specific and clear regulations and limitations, the terms "attach" and "connect" should be understood in a broad sense. For example, it may be a fixed connection, a removably connected, or an integrally connected, directly connected, or indirectly connected. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific situation.

[0041] To better understand the present application, the display panel, display device, and manufacturing method of the display panel of the embodiments of the present application will be described in detail below with reference to FIGS. 1-15.

[0042] FIG. 1 is a schematic structural diagram of a display panel 10 according to an embodiment of the present application, and FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1.

[0043] As shown in FIGS. 1 and 2, an embodiment of the first aspect of the present application provides a display panel 10 including a substrate 100, a first electrode layer 200 provided on the substrate 100, a transparent conductive layer 300, a pixel definition layer 400, and an isolation structure 500. The first electrode layer 200 is installed on the substrate 100, and the first electrode layer 200 includes a plurality of first electrodes 210 distributed at intervals. The transparent conductive layer 300 is installed on one side of the substrate 100, and the transparent conductive layer 300 includes a transparent conductive portion 320. The pixel definition layer 400 is installed on the side of the first electrode layer 200 away from the substrate 100 and covers at least a part of the transparent conductive portion 320. The pixel definition layer 400 includes a pixel limiting portion 410 and a first opening 420 formed in the pixel limiting portion 410. The light-emitting layer includes a light-emitting unit 470 located in the first opening 420. The isolation structure 500 is installed on the side of the pixel definition layer 400 away from the substrate 100. The isolation structure 500 forms an isolation opening 510 and a light-transmitting opening 520 by surrounding. The orthographic projection of the isolation opening 510 on the substrate 100 and the orthographic projection of the first opening 420 on the substrate 100 at least partially overlap, and the orthographic projection of the light-transmitting opening 520 on the substrate 100 and the orthographic projection of the transparent conductive portion 320 on the substrate 100 at least partially overlap.

[0044] In the display panel 10 according to the embodiment of the present application, the display panel 10 includes a substrate 100, a first electrode layer 200 provided on the substrate 100, a light-transmitting conductive layer 300, a pixel definition layer 400, and an isolation structure 500. A first opening 420 for accommodating a light-emitting unit 470 is formed in a pixel-limiting portion 410 of the pixel definition layer 400. By at least partially overlapping the orthographic projection of the first opening 420 on the substrate 100 and the orthographic projection of the first electrode 210 of the first electrode layer 200 on the substrate 100, the first electrode 210 can drive the light-emitting unit 470 in the first opening 420 to emit light. The isolation structure 500 surrounds to form a light-transmitting opening 520 and an isolation opening 510. The isolation opening 510 and the first opening 420 are provided correspondingly and do not affect the light emission of the light-emitting unit 470. The light-transmitting opening 520 can improve the light transmittance of the display panel 10. The light-transmitting conductive layer 300 includes a light-transmitting conductive portion 320. The light-transmitting conductive portion 320 corresponds to the light-transmitting opening 520, and when manufacturing components such as the touch electrode 810 later, it can improve the occurrence of parasitic capacitance between components such as the touch electrode 810 and the conductive line or circuit on the substrate 100. Therefore, the embodiment of the present application can improve the problem of parasitic capacitance by providing the light-transmitting conductive portion 320 and effectively improve the process performance of the display panel 10.

[0045] The installation methods of the substrate 100 are various. The substrate 100 may include a base, and a first conductive layer, a second conductive layer, and a third conductive layer that are installed on one side of the base and stacked. The insulating layer is provided between adjacent conductive layers. Exemplarily, the pixel driving circuit provided on the array substrate 100 includes a transistor and a storage capacitor. The transistor includes a semiconductor, a gate electrode, a source electrode, and a drain electrode. The storage capacitor includes a first electrode plate and a second electrode plate. As an example, the gate electrode and the first electrode plate may be located in the first conductive layer, the second electrode plate may be located in the second conductive layer, and the source electrode and the drain electrode may be located in the third conductive layer. Optionally, the substrate 100 may further include a fourth conductive layer located on the side away from the base of the third conductive layer. A connection signal line may be provided on the fourth conductive layer. The first electrode 210 is connected to the driving circuit via the connection signal line. For example, the first electrode 210 is connected to the source electrode or the drain electrode of the driving transistor via the connection signal line.

[0046] The first electrode 210 is, for example, an anode. The material of the first electrode 210 may include at least one of indium tin oxide or indium zinc oxide. For example, the material of the first electrode 210 includes indium tin oxide to further improve the light transmittance of the display panel 10. Optionally, the material of the first electrode 210 may further include silver. The first electrode 210 includes, for example, a stacked silver metal layer, an indium tin oxide layer, and a silver metal layer. The indium tin oxide layer provides protection for the silver metal layer.

[0047] The installation methods of the material of the transparent conductive layer 300 are various. The material of the transparent conductive layer 300 includes, for example, at least one of indium tin oxide and indium zinc oxide to further improve the light transmittance of the display panel 10.

[0048] In some selectable embodiments, the transparent conductive layer 300 is provided on the side of the substrate 100 away from the first electrode 210, which can improve the influence of the manufacturing and forming of the transparent conductive layer 300 on the first electrode 210.

[0049] Optionally, the transparent conductive layer 300 further includes a first protection portion 310 that covers at least a part of the first electrode 210. When performing a patterning process on the transparent conductive material to form the first protection portion 310 and the transparent conductive portion 320 of the transparent conductive layer 300, the material on the first electrode 210 can be left to form the first protection portion 310, and furthermore, damage to the first electrode 210 caused by the patterning process on the transparent conductive material can be improved.

[0050] Optionally, the orthographic projection of the first opening 420 on the substrate 100 and the orthographic projection of the first protection portion 310 on the substrate 100 overlap at least partially. For example, since the orthographic projection of the first opening 420 on the substrate 100 is located within the orthographic projection of the first protection portion 310 on the substrate 100, the first electrode 210 can drive the light-emitting unit 470 to emit light through the first protection portion 310 and the first opening 420.

[0051] Optionally, the first electrode 210 includes a first sub-layer, a second sub-layer, and a third sub-layer that are laminated in a direction away from the substrate 100, and the first protection portion 310 is located on the side of the third sub-layer away from the second sub-layer. That is, the first protection portion 310 is not a layer structure within the first electrode 210, but a layer structure provided to cover the first electrode 210. The first sub-layer and the third sub-layer may be the above-mentioned silver metal layer, and the second sub-layer may be the above-mentioned indium tin oxide layer.

[0052] The relative positional relationship between the first protection portion 310 and the transparent conductive portion 320 can be set in various ways. For example, as shown in FIG. 4, one first protection portion 310 and at least one transparent conductive portion 320 are connected to each other to form a transparent conductive portion, and each transparent conductive portion is provided insulated from each other with a gap therebetween. Thereby, the transparent conductive portion 320 has the same potential as the first protection portion 310 and further has the same potential as the first electrode 210. The problem that a plurality of transparent conductive portions are installed insulated from each other with a gap therebetween and different first electrodes 210 are short-circuited and connected through the transparent conductive portions can be avoided.

[0053] In some other alternative embodiments, as shown in FIG. 5, the first protection portion 310 and the translucent conductive portion 320 are installed at an interval and insulated from each other. The substrate 100 further includes a second power signal line 120, and the translucent conductive portion 320 and the second power signal line 120 are connected to each other. For example, a via hole is provided in the layer structure between the second power signal line 120 and the translucent conductive portion 320, and the translucent conductive portion 320 is connected to the via hole of the second power signal line 120, so that the translucent conductive portion 320 can have a fixed potential and better improve the problem of parasitic capacitance. The second power signal line 120 may be, for example, a driving power supply voltage signal line.

[0054] Furthermore, in some embodiments, the first protection portion 310 and the translucent conductive portion 320 in the translucent conductive layer 300 are provided at an interval to avoid short-circuit connection between the first protection portion 310 and the translucent conductive portion 320. The first protection portion 310 is located on the side of the substrate 100 away from the first electrode layer 200, and the orthographic projection of the first protection portion 310 on the substrate 100 and the orthographic projection of the first electrode 210 on the substrate 100 are provided at least partially overlapping, and the first protection portion 310 at least partially covers the surface of the first electrode 210 away from the substrate 100, whereby the first protection portion 310 can protect the first electrode 210. When the material of the translucent conductive layer 300 is the same as the material of the first electrode layer 200, in the manufacturing process of the display panel 10, retaining the first protection portion 310 on the first electrode 210 and removing the first protection portion 310 can improve the damage to the first electrode 210, improve the service life of the first electrode 210, and improve the yield of the display panel 10.

[0055] Optionally, the material of the pixel definition layer 400 may be an inorganic material or an organic material. Here, by selecting an inorganic material as the material of the pixel definition layer 400, the thickness of the pixel definition layer 400 can be appropriately reduced, and the overall thickness of the display panel 10 can be reduced. On the other hand, the shape of the second opening 430 can be more easily controlled, and the inclination angle of the wall surface where the pixel limiting portion 410 is installed toward the second opening 430 can be more easily controlled.

[0056] In some selectable embodiments, as shown in FIG. 3, the pixel defining portion 410 is further provided with a second opening 430, and the orthographic projection of the second opening 430 on the substrate 100 is located within the orthographic projection of the light-transmitting opening 520 on the substrate 100. In these embodiments, at least a part of the pixel definition layer 400 on the light-transmitting conductive portion 320 can be removed to further improve the light transmittance of the display panel 10.

[0057] In some other selectable embodiments, as shown in FIG. 2, the pixel definition layer 400 further includes a second protection portion 440, and the second protection portion 440 is located on the side of the light-transmitting conductive portion 320 away from the substrate 100.

[0058] In these selectable embodiments, the second protection portion 440 is provided on the light-transmitting conductive portion 320. When manufacturing the isolation structure 500 in the etching process, the damage to the light-transmitting conductive portion 320 in this process can be improved, the yield of the light-transmitting conductive portion 320 can be increased, and the process yield of the display panel 10 can be increased.

[0059] Optionally, the second protection portion 440 may be located in the pixel definition layer 400, that is, the second protection portion 440 and the pixel defining portion 410 may be provided in the same layer. When manufacturing the pixel definition layer 400, the material on the light-transmitting conductive portion 320 can be reserved to form the second protection portion 440, which can simplify the manufacturing process of the display panel 10 and improve the manufacturing efficiency of the display panel 10.

[0060] Optionally, since the orthographic projection of the light-transmitting conductive portion 320 on the substrate 100 is located within the orthographic projection of the second protection portion 440 on the substrate 100, the second protection portion 440 can provide comprehensive protection for the light-transmitting conductive portion 320.

[0061] Optionally, the orthographic projection of the light-transmitting opening 520 on the substrate 100 is located within the orthographic projection of the second protection portion 440 on the substrate 100, further improving the influence of the isolation structure 500 on the light-transmitting conductive portion 320 when manufacturing the light-transmitting opening 520.

[0062] In some alternative embodiments, the isolation structure 500 and the transparent conductive portion 320 are connected to each other, so that the transparent conductive portion 320 has a fixed potential, and the parasitic capacitance problem can be better improved.

[0063] Optionally, when the transparent conductive layer 300 includes the first protection portion 310 and the isolation structure 500 and the transparent conductive portion 320 are connected to each other, the first protection portion 310 and the transparent conductive portion 320 are provided with an insulating gap therebetween to avoid a short - circuit connection between the isolation structure 500 and the first electrode 210.

[0064] Optionally, as shown in FIG. 3, a first through - hole 450 is formed in the pixel definition layer 400, and the isolation structure 500 is connected to each other through the first through - hole 450 and the transparent conductive portion 320.

[0065] In these alternative embodiments, by providing the first through - hole 450 in the second protection portion 440, the isolation structure 500 can be connected to each other through the first through - hole 450 and the transparent conductive portion 320, the transparent conductive portion 320 can have a fixed potential, and the parasitic capacitance problem can be better improved.

[0066] Optionally, at least one first through - hole 450 is correspondingly provided for each transparent conductive portion 320, that is, each transparent conductive portion 320 is connected to each other through at least one first through - hole 450 and the isolation structure 500, so that each transparent conductive portion 320 can have a fixed potential.

[0067] Optionally, the orthographic projection of the first through - hole 450 on the substrate 100 is located within the orthographic projection of the isolation structure 500 on the substrate 100, that is, the first through - hole 450 is located on the side facing the substrate 100 of the isolation structure 500, the first through - hole 450 is covered by the isolation structure 500, and the first through - hole 450 is provided with a misalignment from the light - transmitting opening 520 and the isolation opening 510, so that the influence on the transparent conductive portion 320 through the first through - hole 450 during the manufacture of the light - transmitting opening 520 and the isolation opening 510 can be improved.

[0068] The installation methods of the shape of the first communication hole 450 are various.

[0069] In some other alternative embodiments, as shown in FIG. 7, at least one first communication hole 450 is provided on at least one side of the light-transmitting opening 520.

For example, an ambient light sensor, a fingerprint sensor, a camera, etc. are provided below the light-transmitting area. The light-transmitting opening 520 may be located only in the light-transmitting area, or the light-transmitting opening 520 may be located in the light-transmitting area and the display area AA other than the light-transmitting area. The light-transmitting area may be a part of the display area AA. In this case, the isolation opening 510 and the light-transmitting opening 520 are provided in the isolation structure 500 of the light-transmitting area, and a light-emitting unit is provided in the isolation opening 510, so that the light-transmitting area has a display function and a light-transmitting function.

[0072] The installation methods of the isolation structure 500 are various. For example, the isolation structure 500 includes a first sub-layer 501 and a second sub-layer 502 located on the side away from the substrate 100 of the first sub-layer 501. The orthographic projection of the first sub-layer 501 on the substrate 100 is located within the orthographic projection of the second sub-layer 502 on the substrate 100. Thereby, the projected area of the second sub-layer 502 can be made larger than the projected area of the first sub-layer 501, and a depression can be formed in the second sub-layer 502. During the subsequent manufacturing of the light-emitting unit 470, the light-emitting material can be cut at the edge position of the second sub-layer 502, the precise mask process can be omitted, and the manufacturing process of the display panel 10 can be simplified.

Alternatively, in some other embodiments, the isolation structure 500 further includes a third sub-layer 503 located on the side facing the substrate 100 of the first protection part 310. The orthographic projection of the first sub-layer 501 on the substrate 100 is located in the orthographic projection of the third sub-layer 503 on the substrate 100.

[0075] Also, by providing the third sub-layer 503, when the first sub-layer 501 is side-etched so that the orthographic projection of the first sub-layer 501 on the substrate 100 is located within the orthographic projection of the second sub-layer 502 on the substrate 100, the material located under the third sub-layer 503 can be protected, and damage to the layer structure under the third sub-layer 503 can be avoided.

[0076] In some embodiments, the display panel 10 further includes a second electrode layer 600. The second electrode layer 600 includes a second electrode 610 located on the side away from the substrate 100 of the light-emitting unit 470. The second electrode 610 is connected to the isolation structure 500. Thereby, the plurality of second electrodes 610 are connected to each other via the isolation structure 500 to form a planar electrode.

[0077] The second electrode 610 may be connected to the first sub-layer 501 of the isolation structure 500. Optionally, when the isolation structure 500 includes a third sub-layer 503, the second electrode 610 may be connected to the third sub-layer 503 of the isolation structure 500, or the second electrode 610 may be connected to the first sub-layer 501 and the third sub-layer 503 of the isolation structure 500.

[0078] Optionally, the material of the first sub-layer 501 includes a conductive material, and the second electrode 610 and the first sub-layer 501 are electrically connected to each other. Optionally, the material of the second sub-layer 502 may include a conductive material to increase the distribution area of the conductive part in the isolation structure 500 and reduce the overall resistance of the second electrode 610. Optionally, the material of the third sub-layer 503 includes a conductive material to further isolate the distribution area of the conductive part in the structure 500 and reduce the overall resistance of the second electrode 610.

[0079] In some selectable embodiments, as shown in FIG. 9, the display panel 10 further includes a first power signal line 110. The first power signal line 110 is located inside or on the side of the substrate 100. A second through-hole 460 is formed in the pixel defining portion 410. The isolation structure 500 is connected to the first power signal line 110 through the second through-hole 460.

[0080] In these selectable embodiments, a second through-hole 460 is further formed in the pixel defining portion 410. The isolation structure 500 is connected to the first power signal line 110 inside the substrate 100 through the second through-hole 460, and the mutual transmission of the signal lines can be realized.

[0081] Optionally, the first power signal line 110 may be located in the fourth conductive layer so as to reduce the distance between the first power signal line 110 and the isolation structure 500 and facilitate the electrical connection between the first power signal line 110 and the isolation structure 500.

[0082] Optionally, both the pixel defining portion 410 and the second protection portion 440 are part of the pixel definition layer 400. The pixel defining portion 410 and the second protection portion 440 are members in different regions of the pixel definition layer 400, and there may not be an obvious boundary between the pixel defining portion 410 and the second protection portion 440. The second through hole 460 and the first through hole 450 may be manufactured in the same process step to further simplify the manufacturing process of the display panel 10.

[0083] Optionally, the display panel 10 further includes a non-display area NA provided to surround at least a part of the display area AA. The second through hole 460 can be located in the non-display area NA, whereby the isolation structure 500 is electrically connected to the first power signal line 110 in the non-display area NA, and the second through hole 460 improves the influence on the structure within the display area AA.

[0084] Optionally, a dam structure 700 is further provided on the substrate 100 of the display panel 10. The dam structure 700 is provided to surround the display area AA. The second through hole 460 may be provided on the side of the dam structure 700 facing the display area AA. Furthermore, the entire isolation structure 500 may be located on the side of the dam structure 700 facing the display area AA, and the structure of the isolation structure 500 can be simplified.

[0085] Optionally, the display panel 10 further includes a sealing layer 900. The sealing layer 900 may include a first sealing layer. The first sealing layer includes a sealing portion 910 located on the side of each second electrode 610 away from the substrate 100. The sealing portion 910 can provide sealing protection for each light emitting unit 470. The material of the first sealing layer can protect inorganic materials.

[0086] Optionally, the encapsulation layer 900 further includes a second encapsulation layer 920 located on the side of the first encapsulation layer away from the substrate 100. The second encapsulation layer 920 is located on the side facing the display area AA of the dam structure 700, and the dam structure 700 can improve the situation where the material of the second encapsulation layer 920 overflows to the side away from the display area AA of the dam structure 700. The material of the second encapsulation layer 920 may include an organic material.

[0087] Optionally, the second encapsulation layer 920 is in contact with and connected to at least a part of the second protection part 440. For example, the first encapsulation layer 900 does not seal the light-transmitting opening 520, and the first encapsulation layer 900 seals only the area where the isolation opening 510 is located. Thus, the second encapsulation layer 920 can be directly in contact with and connected to the second protection part 440 within the light-transmitting opening 520.

[0088] Optionally, the encapsulation layer 900 further includes a third encapsulation layer 930 located on the side of the second encapsulation layer 920 away from the substrate 100. The material of the third encapsulation layer 930 may be the same as the material of the first encapsulation layer. For example, the material of the third encapsulation layer 930 is an inorganic material.

[0089] Optionally, the display panel 10 further includes a touch function layer 800, and the touch function layer 800 is located on the side of the encapsulation layer 900 away from the substrate 100.

In the process of installing the touch electrodes 810, some of the touch electrodes 810 are located above the light-transmitting opening 520, that is, at least partially overlapping, the orthographic projection of some of the touch electrodes 810 on the substrate 100 and the orthographic projection of the light-transmitting opening 520 on the substrate 100 are installed. At this time, the light-transmitting conductive part 320 is installed corresponding to the light-transmitting opening 520. The light-transmitting conductive part 320 plays a shielding role, improves the parasitic capacitance generated between the touch electrode 810 and other signal lines in the array substrate 100, and can improve the stability of touch signal transmission.

[0091] In some alternative embodiments, the orthographic projection of the first electrode 210 on the substrate 100 is located within the orthographic projection of the first protection part 310 on the substrate 100. Thereby, the size of the first protection part 310 can be made larger than the size of the first electrode 210, and the first protection part 310 can provide overall protection for the first electrode 210.

[0092] Optionally, the first electrode 210 includes a top surface away from the substrate 100 and a side surface connected to the peripheral side of the top surface and extending toward the substrate 100.

The central region is located on the side away from the substrate 100 of the first protection part 310, and the edge region is connected to the peripheral side of the central region and is in contact with and connected to the substrate 100. The size of the first protection part 310 is larger than that of the first electrode 210, and by forming an edge region that protrudes from the first electrode 210 and contacts the substrate 100, the first protection part 310 can provide more comprehensive protection for the first electrode 210.

[0094] An embodiment of the second aspect of the present application further provides a display device including the display panel 1010 of any of the above embodiments of the first aspect. Since the display device according to the embodiment of the second aspect of the present application includes the display panel 1010 of any one of the above embodiments of the first aspect, the display device according to the embodiment of the second aspect of the present application has the beneficial effects of the display panel 1010 of any one of the above embodiments of the first aspect, and the description thereof is omitted herein.

[0095] The display device in the embodiments of the present application includes, but is not limited to, devices having a display function such as mobile phones, personal digital assistants (abbreviated as PDAs), tablet computers, e-books, televisions, door access, smart landline phones, and consoles.

[0096] An embodiment of the third aspect of the present application further provides a manufacturing method of a display panel 10. The display panel 10 may be the display panel 10 according to any of the above embodiments of the first aspect. As shown in FIGS. 1-10, the manufacturing method of the display panel 10 includes the following steps.

[0097] In step S01, as shown in FIG. 11, a material layer of the first electrode 210 is disposed on the substrate 100, and a patterning process is performed on the material layer of the first electrode 210 to form the first electrode layer 200. The first electrode layer 200 includes a plurality of first electrodes 210 provided at intervals.

[0098] In step S02, as shown in FIG. 12, a conductive functional material layer is continuously disposed on the substrate 100, and a patterning process is performed on the conductive functional material layer to fabricate the transparent conductive layer 300. The transparent conductive layer 300 includes a transparent conductive portion 320.

[0099] Optionally, as shown in FIG. 12, in step S02, the transparent conductive layer 300 may further include a first protection portion 310. The first protection portion 310 covers at least a part of the first electrodes 210, and the first protection portion 310 can protect the first electrodes 210.

[0100] In step S03, as shown in FIG. 13, a pixel defining material layer is disposed on the substrate 100.

[0101] In step S04, as shown in FIG. 14, an isolation structure 500 is fabricated on the side of the pixel defining material layer away from the substrate 100. The isolation structure 500 surrounds to form an isolation opening 510 and a light-transmitting opening 520, and the orthographic projection of the light-transmitting opening 520 on the substrate 100 at least partially overlaps with the orthographic projection of the light-transmitting conductive portion 320 on the substrate 100.

[0102] In step S05, as shown in FIG. 15, patterning treatment is performed on the pixel defining material layer exposed from the isolation opening 510 to form a first opening 420.

[0103] Optionally, when the light-transmitting conductive layer 300 includes the first protection portion 310, at least a part of the first protection portion 310 is exposed from the first opening 420. This makes it easier for the subsequent light-emitting unit 470 to be connected to the first electrode 210 via the first protection portion 310.

[0104] In the manufacturing method of the display panel 10 according to the embodiment of the present application, after manufacturing the first electrode layer 200, when continuously manufacturing the light-transmitting conductive layer 300 and performing patterning treatment on the conductive functional material layer, by retaining the first protection portion 310 located on the first electrode 210, the problem that the first electrode 210 is easily damaged under the influence of this process can be improved. Further, after manufacturing the isolation structure 500, by performing patterning treatment on the pixel defining material layer in step S05 to form the first opening 420, the pixel defining material layer improves the protection of the light-transmitting conductive layer 300 in step S04, improves the patterning treatment, and affects the light-transmitting conductive layer 300 when manufacturing the isolation structure 500, thereby improving the process performance of the display panel 10.

[0105] In addition, the first opening 420 is for accommodating the light-emitting unit 470. By at least partially overlapping the orthographic projection of the first opening 420 on the substrate 100 and the orthographic projection of the first electrode 210 of the first electrode layer 200 on the substrate 100, the first electrode 210 can drive the light-emitting unit 470 in the first opening 420 to emit light. The isolation structure 500 forms a light-transmitting opening 520 and an isolation opening 510 by surrounding them. The isolation opening 510 and the first opening 420 are provided correspondingly and do not affect the light emission of the light-emitting unit 470. The light-transmitting opening 520 can improve the light transmittance of the display panel 10. The light-transmitting conductive part 320 corresponds to the light-transmitting opening 520, and when manufacturing members such as the touch electrode 810 later, it can improve the occurrence of parasitic capacitance between members such as the touch electrode 810 and the conductive line or circuit on the substrate 100. Therefore, the embodiment of the present application can not only improve the problem of being easily damaged in the manufacturing process of the first electrode 210 by providing the first protection part 310 and the light-transmitting conductive part 320, but also improve the problem of parasitic capacitance, and can effectively improve the process performance of the display panel 10.

[0106] In some selectable embodiments, when performing a patterning process on the pixel definition material layer in step S05, a second protection part 440 can be formed by leaving a part of the pixel definition material layer located on the side away from the substrate 100 of the light-transmitting conductive part 320, and the second protection part 440 can protect the light-transmitting conductive part 320. Alternatively, in step S05, a part of the pixel definition material layer located in the light-transmitting conductive part 320 can be removed to form a second opening 430, and the light transmittance of the display panel 10 can be further improved.

[0107] In some selectable embodiments, as shown in FIG. 13, in step S03, a patterning process is performed on the pixel definition material layer to create a first through hole 450, and a part of the light-transmitting conductive part 320 is exposed from the first through hole 450. When manufacturing the isolation structure 500 in the subsequent step S04, the isolation structure 500 can be connected to the light-transmitting conductive part 320 through the first through hole 450, so that the light-transmitting conductive part 320 can have a fixed potential and better improve the problem of parasitic capacitance.

[0108] Optionally, the display panel 10 further includes a first power signal line 110, the first power signal line 110 is located inside or on the side of the substrate 100, and in step S03, a patterning process can also be performed on the pixel definition material layer to form a second through hole 460, and a part of the first power signal line 110 is exposed from the second through hole 460. When manufacturing the isolation structure 500 in the subsequent step S04, the isolation structure 500 can be connected to the first power signal line 110 through the second through hole 460.

[0109] As mentioned above, the present application has been described with reference to preferred embodiments. However, various modifications and equivalent substitutions are possible without departing from the gist of the present application. In particular, each technical feature described in each embodiment can be arbitrarily combined as long as there is no structural contradiction. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions included in the scope of the claims.
