In the following detailed description, many specific details are proposed to provide a comprehensive understanding of the present application.

A person skilled in the art will be able to understand the specific meaning of the above terms in this application depending on the specific circumstances.

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

[0042] Figure 1 is a schematic diagram of the structure of the display panel 10 according to an embodiment of the present application, and Figure 2 is a cross-sectional view of AA in Figure 1.

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

[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, a light-transmitting conductive layer 300, a pixel definition layer 400, and an isolation structure 500 provided on the substrate 100. A first aperture 420 for housing a light-emitting unit 470 is provided in the pixel limiting portion 410 of the pixel definition layer 400. The orthographic projection of the first aperture 420 on the substrate 100 and the orthographic projection of the first electrode 210 of the first electrode layer 200 on the substrate 100 overlap at least partially, so that the first electrode 210 can drive the light-emitting unit 470 in the first aperture 420 to emit light. The isolation structure 500 surrounds and forms a light-transmitting aperture 520 and an isolation aperture 510, and the isolation aperture 510 and the first aperture 420 are provided correspondingly and do not affect the light emission of the light-emitting unit 470. The light-transmitting aperture 520 can improve the light transmittance of the display panel 10. The light-transmitting conductive layer 300 includes a light-transmitting conductive portion 320, which corresponds to a light-transmitting aperture 520. This improves the problem of parasitic capacitance occurring between components such as touch electrodes 810 and conductive wires or circuits in the substrate 100 when components such as touch electrodes 810 are manufactured thereafter. Therefore, the embodiment of the present application can improve the parasitic capacitance problem by providing the light-transmitting conductive portion 320, and can effectively improve the process performance of the display panel 10.

[0045] The substrate 100 can be installed in various ways, and may include a base and a first conductive layer, a second conductive layer, and a third conductive layer installed on one side of the base and stacked thereon. An insulating layer is provided between adjacent conductive layers. Exemplarily, a 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 and a second electrode. For example, the gate electrode and the first electrode may be located on the first conductive layer, the second electrode on the second conductive layer, and the source electrode and drain electrode on the third conductive layer. Optionally, the substrate 100 may further include a fourth conductive layer located away from the base of the third conductive layer, and connection signal lines may be provided on the fourth conductive layer, and the first electrode 210 is connected to the driving circuit via the connection signal lines, for example, the first electrode 210 is connected to the source electrode or drain electrode of the driving transistor via the connection signal lines.

[0046] The first electrode 210 is, for example, an anode, and 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 may include indium tin oxide to further improve the light transmittance of the display panel 10. Selectively, the material of the first electrode 210 may further include silver, and the first electrode 210 may include, for example, a laminated silver metal layer, an indium tin oxide layer and a silver metal layer, with the indium tin oxide layer providing protection to the silver metal layer.

[0047] There are various methods for installing the material of the light-transmitting conductive layer 300. For example, the material of the light-transmitting conductive layer 300 may include 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 light-transmitting conductive layer 300 is provided on the side of the first electrode 210 away from the substrate 100, which can improve the influence of the manufacturing and molding of the light-transmitting conductive layer 300 on the first electrode 210.

[0049] Selectively, the light-transmitting conductive layer 300 further includes a first protective portion 310 that covers at least a portion of the first electrode 210. When patterning is performed on the light-transmitting conductive material to form the first protective portion 310 and the light-transmitting conductive portion 320 of the light-transmitting conductive layer 300, the first protective portion 310 can be formed while leaving material on the first electrode 210, and further damage to the first electrode 210 due to the patterning process on the light-transmitting conductive material can be improved.

[0050] Selectively, the orthographic projection of the first aperture 420 on the substrate 100 and the orthographic projection of the first protective portion 310 on the substrate 100 overlap at least partially. For example, the orthographic projection of the first aperture 420 on the substrate 100 is located within the orthographic projection of the first protective portion 310 on the substrate 100, so that the first electrode 210 can drive the light-emitting unit 470 via the first protective portion 310 and the first aperture 420 to emit light.

[0051] Selectively, the first electrode 210 includes a first sublayer, a second sublayer, and a third sublayer, which are stacked in a direction away from the substrate 100, and the first protective portion 310 is located on the side of the third sublayer away from the second sublayer. That is, the first protective 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 and third sublayers may be the silver metal layers, and the second sublayer may be the indium tin oxide layer.

[0052] The relative positional relationship between the first protective section 310 and the light-transmitting conductive section 320 can vary. For example, as shown in Figure 4, one first protective section 310 and at least one light-transmitting conductive section 320 are connected to each other to form a light-transmitting conductive section, and each light-transmitting conductive section is provided spaced apart and insulated from one another. This ensures that the light-transmitting conductive section 320 has the same potential as the first protective section 310 and also has the same potential as the first electrode 210. Multiple light-transmitting conductive sections are provided spaced apart and insulated from one another, avoiding the problem of different first electrodes 210 being short-circuited and connected via the light-transmitting conductive sections.

[0053] In some other selectable embodiments, as shown in Figure 5, the first protective section 310 and the light-transmitting conductive section 320 are installed spaced apart and insulated from each other, and the substrate 100 further includes a second power signal line 120, with the light-transmitting conductive section 320 and the second power signal line 120 connected to each other. For example, a via hole is provided in the layer structure between the second power signal line 120 and the light-transmitting conductive section 320, and the light-transmitting conductive section 320 is connected to the via hole of the second power signal line 120, thereby allowing the light-transmitting conductive section 320 to have a fixed potential and better improving the parasitic capacitance problem. The second power signal line 120 may be, for example, a drive power supply voltage signal line.

[0054] Furthermore, in some embodiments, the first protective portion 310 and the light-transmitting conductive portion 320 in the light-transmitting conductive layer 300 are spaced apart to avoid short-circuit connections between the first protective portion 310 and the light-transmitting conductive portion 320. The first protective portion 310 is located on the side of the first electrode layer 200 away from the substrate 100, and the orthographic projection of the first protective portion 310 on the substrate 100 and the orthographic projection of the first electrode 210 on the substrate 100 overlap at least partially, so that the first protective portion 310 covers at least partially the surface of the first electrode 210 away from the substrate 100, thereby enabling the first protective portion 310 to protect the first electrode 210. If the material of the light-transmitting conductive layer 300 is the same as the material of the first electrode layer 200, the manufacturing process of the display panel 10 can be improved by retaining the first protective part 310 on the first electrode 210 and preventing damage to the first electrode 210 when the first protective part 310 is removed, thereby improving the service life of the first electrode 210 and improving the yield of the display panel 10.

[0055] Selectively, the material of the pixel definition layer 400 may be an inorganic material or an organic material. 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, thereby reducing the overall thickness of the display panel 10. At the same time, the shape of the second aperture 430 can be more easily controlled, and the inclination angle of the wall surface on which the pixel limiting portion 410 is installed facing the second aperture 430 can be more easily controlled.

[0056] In some selectable embodiments, as shown in Figure 3, a second aperture 430 is further provided in the pixel limiting portion 410, and the orthographic projection of the second aperture 430 on the substrate 100 lies within the orthographic projection of the light-transmitting aperture 520 on the substrate 100. In these embodiments, the light transmittance of the display panel 10 can be further improved by removing at least a portion of the pixel definition layer 400 on the light-transmitting conductive portion 320.

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

[0058] In these selectable embodiments, the light-transmitting conductive portion 320 is provided with a second protective portion 440, which improves damage to the light-transmitting conductive portion 320 during the etching process when manufacturing the isolation structure 500, improves the yield of the light-transmitting conductive portion 320, and improves the process yield of the display panel 10.

[0059] Selectively, the second protective portion 440 may be located on the pixel definition layer 400, that is, the second protective portion 440 and the pixel limiting portion 410 may be provided on the same layer. When manufacturing the pixel definition layer 400, the material on the light-transmitting conductive portion 320 can be retained while forming the second protective portion 440, thereby simplifying the manufacturing process of the display panel 10 and improving the manufacturing efficiency of the display panel 10.

[0060] By selectively positioning the orthographic projection of the light-transmitting conductive portion 320 on the substrate 100 within the orthographic projection of the second protective portion 440 on the substrate 100, the second protective portion 440 can be provided with complete protection by the light-transmitting conductive portion 320.

[0061] Selectively, the orthographic projection of the light-transmitting aperture 520 on the substrate 100 is located within the orthographic projection of the second protective 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 aperture 520.

[0062] In some selectable embodiments, the isolation structure 500 and the light-transmitting conductive portion 320 are connected to each other, giving the light-transmitting conductive portion 320 a fixed potential, which can better improve the parasitic capacitance problem.

[0063] If the light-transmitting conductive layer 300 selectively includes the first protective portion 310 and the isolation structure 500 and the light-transmitting conductive portion 320 are connected to each other, the first protective portion 310 and the light-transmitting conductive portion 320 are provided with a gap between them and insulated from each other, thereby avoiding a short circuit between the isolation structure 500 and the first electrode 210.

[0064] Selectively, as shown in Figure 3, a first communication hole 450 is provided in the pixel definition layer 400, and the isolation structure 500 is connected to each other via the first communication hole 450 and the light-transmitting conductive portion 320.

[0065] In these selectable embodiments, by providing the first communication hole 450 in the second protective part 440, the isolation structure 500 can be connected to each other via the first communication hole 450 and the light-transmitting conductive part 320, the light-transmitting conductive part 320 can have a fixed potential, and the parasitic capacitance problem is better improved.

[0066] Selectively, each light-transmitting conductive portion 320 is provided with at least one corresponding first communication hole 450, that is, each light-transmitting conductive portion 320 is connected to one another via at least one first communication hole 450 and an isolation structure 500, so that each light-transmitting conductive portion 320 can have a fixed potential.

[0067] Selectively, the orthographic projection of the first communication hole 450 on the substrate 100 lies within the orthographic projection of the isolation structure 500 on the substrate 100, that is, the first communication hole 450 is located on the side of the isolation structure 500 facing the substrate 100, the first communication hole 450 is covered by the isolation structure 500, the first communication hole 450 is offset from the light-transmitting opening 520 and the isolation opening 510, and it is possible to improve the effect on the light-transmitting conductive part 320 through the first communication hole 450 when manufacturing the light-transmitting opening 520 and the isolation opening 510.

[0068] The shape of the first communication hole 450 can be installed in various ways. As shown in Figure 6, the first communication hole 450 can be annular in shape, surrounding the light-transmitting opening 520. The isolation structures 500 located on the periphery of the light-transmitting opening 520 can all be connected to the light-transmitting conductive part 320 via the first communication hole 450. This improves the contact area between the isolation structure 500 and the light-transmitting conductive part 320 and improves the yield of connections between the isolation structure 500 and the light-transmitting conductive part 320.

[0069] In some other selectable embodiments, as shown in Figure 7, at least one first communication hole 450 is provided on at least one side of the light-transmitting opening 520, for example, a plurality of first communication holes 450 are spaced apart to surround the light-transmitting opening 520, and isolation structures 500 located at different positions on the periphery of the light-transmitting opening 520 are connected to the light-transmitting conductive portion 320 via different first communication holes 450.

[0070] Selectively, as shown in Figures 8 and 9, the display panel 10 includes a display area AA, and both the first opening 420 and the isolation opening 510 can be located in the display area AA, and the light-emitting unit 470 emits light and displays within the display area AA. The first communication hole 450 may also be located in the display area AA, and the first communication hole 450 may connect the isolation structure 500 of the display area AA to the light-transmitting conductive part 320.

[0071] Selectively, the display panel 10 further includes a light-transmitting area, which is an area where sensors are provided. For example, an ambient light sensor, a fingerprint sensor, a camera, etc., may be provided below the light-transmitting area. The light-transmitting aperture 520 may be located only in the light-transmitting area, or it 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 structure 500 for the light-transmitting area is provided with an isolation aperture 510 and a light-emitting unit, and a light-emitting unit is provided in the isolation aperture 510, thereby giving the light-transmitting area both a display function and a light-transmitting function.

[0072] The isolation structure 500 can be installed in various ways. For example, the isolation structure 500 includes a first sub-layer 501 and a second sub-layer 502 located on the side of the first sub-layer 501 away from the substrate 100, such that the orthographic projection of the first sub-layer 501 on the substrate 100 lies within the orthographic projection of the second sub-layer 502 on the substrate 100. This makes the projection area of ​​the second sub-layer 502 larger than that of the first sub-layer 501, allowing a recess to 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, eliminating the need for a precision mask process and simplifying the manufacturing process of the display panel 10.

[0073] Selectively, as described above, when the isolation structure 500 includes a first sublayer 501 and a second sublayer 502, the first sublayer 501 is connected to the first through-hole 450 and the light-transmitting conductive portion 320. The first sublayer 501 is closer to the light-transmitting conductive portion 320 than the second sublayer 502, and the first sublayer 501 is more easily connected to the first through-hole 450 and the light-transmitting conductive portion 320.

[0074] The first sublayer 501 and the light-transmitting conductive portion 320 may be directly connected to each other. Alternatively, in some other embodiments, the isolation structure 500 further includes a third sublayer 503 located on the substrate 100 side of the first protective portion 310, where the orthographic projection of the first sublayer 501 on the substrate 100 is located on the orthographic projection of the third sublayer 503 on the substrate 100, and the third sublayer 503 is connected to each other via the first communication hole 450 and the light-transmitting conductive portion 320, such that the first sublayer 501 is connected to the light-transmitting conductive portion 320 via the third sublayer 503.

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

[0076] In some embodiments, the display panel 10 further includes a second electrode layer 600, the second electrode layer 600 including a second electrode 610 located on the side of the light-emitting unit 470 away from the substrate 100, the second electrode 610 being connected to an isolation structure 500. This allows multiple second electrodes 610 to be connected to each other via the isolation structure 500 to form a surface electrode.

[0077] The second electrode 610 may be connected to the first sublayer 501 of the isolation structure 500. Selectively, if the isolation structure 500 includes a third sublayer 503, the second electrode 610 may be connected to the third sublayer 503 of the isolation structure 500, or the second electrode 610 may be connected to both the first sublayer 501 and the third sublayer 503 of the isolation structure 500.

[0078] Selectively, the material of the first sublayer 501 includes a conductive material, and the second electrode 610 and the first sublayer 501 are electrically connected to each other. Selectively, the material of the second sublayer 502 may also include a conductive material, increasing the distribution area of ​​the conductive portion in the isolation structure 500 and reducing the overall resistance of the second electrode 610. Selectively, the material of the third sublayer 503 includes a conductive material, further isolating the distribution area of ​​the conductive portion in the structure 500 and reducing the overall resistance of the second electrode 610.

[0079] In some selectable embodiments, as shown in Figure 9, the display panel 10 further includes a first power signal line 110 located within or on the substrate 100, with a second communication hole 460 provided in the pixel limiting section 410, and the isolation structure 500 connected to the first power signal line 110 via the second communication hole 460.

[0080] In these selectable embodiments, a second communication hole 460 is further provided in the pixel limiting portion 410, and the isolation structure 500 is connected to the first power signal line 110 in the substrate 100 via the second communication hole 460, thereby enabling mutual transmission of signal lines.

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

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

[0083] Selectively, the display panel 10 further includes a non-display area NA provided to surround at least a portion of the display area AA. The second communication hole 460 may be located in the non-display area NA, thereby electrically connecting the isolation structure 500 to the first power signal line 110 in the non-display area NA and improving the influence of the second communication hole 460 on the structure within the display area AA.

[0084] Selectively, the substrate 100 of the display panel 10 may be further provided with a dam structure 700, the dam structure 700 may be provided so as to surround the display area AA, the second communication hole 460 may be provided on the side of the dam structure 700 facing the display area AA, and furthermore, the entire isolation structure 500 may be located on the side of the dam structure 700 facing the display area AA, thereby simplifying the structure of the isolation structure 500.

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

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

[0087] Selectively, the second sealing layer 920 is connected in contact with at least a portion of the second protective portion 440, for example, the first sealing layer 900 does not seal the light-transmitting opening 520, and the first sealing layer 900 seals only the region where the isolation opening 510 is located, thereby allowing the second sealing layer 920 to be connected in direct contact with the second protective portion 440 within the light-transmitting opening 520.

[0088] Selectively, the sealing layer 900 further includes a third sealing layer 930 located on the side of the second sealing layer 920 away from the substrate 100, wherein the material of the third sealing layer 930 may be the same as the material of the first sealing layer, for example, the material of the third sealing layer 930 may be an inorganic material.

[0089] Selectively, the display panel 10 further includes a touch function layer 800, which is located on the side of the sealing layer 900 away from the substrate 100. The touch function layer 800 includes a first touch layer and a second touch layer, with an insulating layer provided between the first and second touch layers. A touch electrode 810 is provided on one of the first and second touch layers, and a bridge portion 820 is provided on the other, connecting adjacent touch electrodes 810 using via holes in the bridge portion 820.

[0090] Selectively, the orthographic projection of at least some of the touch electrodes 810 on the substrate 100 and the orthographic projection of the light-transmitting aperture 520 on the substrate 100 are arranged to overlap by at least a portion. During the installation process of the touch electrodes 810, some of the touch electrodes 810 are positioned above the light-transmitting aperture 520, that is, the orthographic projection of some of the touch electrodes 810 on the substrate 100 and the orthographic projection of the light-transmitting aperture 520 on the substrate 100 are installed to overlap by at least a portion. At this time, the light-transmitting conductive portion 320 is installed corresponding to the light-transmitting aperture 520, and the light-transmitting conductive portion 320 acts as a shield, improving parasitic capacitance that occurs between the touch electrodes 810 and other signal lines in the array substrate 100, thereby improving the stability of touch signal transmission.

[0091] In some selectable embodiments, the orthographic projection of the first electrode 210 on the substrate 100 lies within the orthographic projection of the first protective section 310 on the substrate 100. This allows the size of the first protective section 310 to be larger than the size of the first electrode 210, so that the first protective section 310 can provide more comprehensive protection to the first electrode 210.

[0092] Selectively, the first electrode 210 includes a top surface away from the substrate 100 and a side surface connected to the circumferential side of the top surface and extending toward the substrate 100, and the first protective portion 310 can cover the top surface and the side surface, thereby avoiding damage to the first electrode 210 by the top surface or the side surface when patterning the light-transmitting conductive layer 300.

[0094] Embodiments of a second aspect of the present application further provide a display device including a display panel 1010 of any of the embodiments of the first aspect described above. Since the display device according to the embodiment of the second aspect of the present application includes a display panel 1010 of any of the embodiments of the first aspect described above, 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 of the embodiments of the first aspect described above, which are omitted from this explanation.

[0095] The display devices in the embodiments of this application include, but are not limited to, devices having display functions such as mobile phones, personal digital assistants (PDAs), tablet computers, e-readers, televisions, door access devices, smart landline phones, and consoles.

[0096] A third embodiment of the present application further provides a method for manufacturing a display panel 10, the display panel 10 may be the display panel 10 according to any of the first embodiments described above, and as shown in Figures 1-10, the method for manufacturing the display panel 10 includes the following steps.

[0097] In step S01, as shown in Figure 11, a material layer for the first electrode 210 is placed on the substrate 100, and a patterning process is performed on the material layer for the first electrode 210 to form a first electrode layer 200, the first electrode layer 200 includes a plurality of first electrodes 210 that are spaced apart.

[0098] In step S02, as shown in Figure 12, the conductive functional material layer is continuously placed on the substrate 100, and a patterning process is performed on the conductive functional material layer to create a light-transmitting conductive layer 300, which includes a light-transmitting conductive portion 320.

[0099] Selectively, as shown in Figure 12, in step S02, the light-transmitting conductive layer 300 may further include a first protective portion 310, the first protective portion 310 covering at least a portion of the first electrode 210, and the first protective portion 310 protecting the first electrode 210.

[0100] In step S03, a pixel definition material layer is placed on the substrate 100, as shown in Figure 13.

[0101] In step S04, as shown in Figure 14, an isolation structure 500 is fabricated on the side away from the substrate 100 of the pixel-defining material layer, and the isolation structure 500 surrounds and forms 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 Figure 15, a patterning process is performed on the pixel definition material layer exposed from the isolation aperture 510 to create the first aperture 420.

[0103] If the light-transmitting conductive layer 300 selectively includes a first protective portion 310, at least a portion of the first protective portion 310 is exposed through the first opening 420. This facilitates the connection of the subsequent light-emitting unit 470 to the first electrode 210 via the first protective 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, the light-transmitting conductive layer 300 is manufactured, and when patterning is performed on the conductive functional material layer, the first protective part 310 located on the first electrode 210 is retained, thereby improving the problem that the first electrode 210 is susceptible to damage during this process. Furthermore, after manufacturing the isolation structure 500, in step S05, patterning is performed on the pixel definition material layer to create the first aperture 420, thereby improving the protection of the light-transmitting conductive layer 300 by the pixel definition material layer in step S04, improving the patterning process to affect the light-transmitting conductive layer 300 when manufacturing the isolation structure 500, and improving the process performance of the display panel 10.

[0105] Furthermore, the first aperture 420 is for housing the light-emitting unit 470, and the orthographic projection of the first aperture 420 on the substrate 100 and the orthographic projection of the first electrode 210 of the first electrode layer 200 on the substrate 100 overlap at least partially, so that the first electrode 210 can drive the light-emitting unit 470 in the first aperture 420 to emit light. The isolation structure 500 surrounds and forms the light-transmitting aperture 520 and the isolation aperture 510, and the isolation aperture 510 and the first aperture 420 are provided correspondingly and do not affect the light emission of the light-emitting unit 470. The light-transmitting aperture 520 can improve the light transmittance of the display panel 10, and the light-transmitting conductive part 320 corresponds to the light-transmitting aperture 520 and can improve the occurrence of parasitic capacitance between components such as the touch electrode 810 and conductive wires or circuits on the substrate 100 when components such as the touch electrode 810 are manufactured thereafter. Therefore, by providing the first protective portion 310 and the light-transmitting conductive portion 320, the embodiment of the present application can not only improve the problem of the first electrode 210 being easily damaged during the manufacturing process, but also improve the problem of parasitic capacitance, thereby effectively improving the process performance of the display panel 10.

[0106] In some selectable embodiments, when patterning the pixel definition material layer in step S05, the second protective portion 440 can be formed while leaving a portion of the pixel definition material layer located on the side of the light-transmitting conductive portion 320 away from the substrate 100, and the second protective portion 440 can protect the light-transmitting conductive portion 320. Alternatively, in step S05, a portion of the pixel definition material layer located on the light-transmitting conductive portion 320 may be removed to form a second aperture 430, further improving the light transmittance of the display panel 10.

[0107] In some selectable embodiments, as shown in Figure 13, in step S03, a patterning process is performed on the pixel-defining material layer to create a first communication hole 450, and a portion of the light-transmitting conductive portion 320 is exposed through the first communication hole 450. In the subsequent step S04, when manufacturing the isolation structure 500, the isolation structure 500 can be connected to the light-transmitting conductive portion 320 via the first communication hole 450, allowing the light-transmitting conductive portion 320 to have a fixed potential, which better improves the parasitic capacitance problem.

[0108] Selectively, the display panel 10 further includes a first power signal line 110, the first power signal line 110 located within or on the substrate 100, and in step S03, a patterning process can be performed on the pixel definition material layer to create a second communication hole 460, with a portion of the first power signal line 110 exposed through the second communication hole 460. When the isolation structure 500 is manufactured in the later step S04, the isolation structure 500 can be connected to the first power signal line 110 via the second communication hole 460.
