[0104] OLED (Organic Light-Emitting Diode) has the characteristics of self-luminescence, high brightness, wide viewing angle, high contrast, flexibility, and low energy consumption. Therefore, it has attracted widespread attention. As a new generation of display method, it has begun to gradually replace traditional liquid crystal displays and is widely used in mobile phone screens, computer monitors, full-color TVs, etc.

[0105] However, in the related art, the organic light-emitting layer of the OLED display panel is easily corroded by water and oxygen during the etching process, resulting in poor display effect of the display panel.

[0106] Based on the above technical problems, the present application provides a display panel and a manufacturing method thereof, as well as a display device, so as to improve the display effect of the display panel.

[0107] First, see Figures 1 to 7 As shown, the embodiment of the present application provides a display panel 10, including a substrate 110, a first light-emitting functional portion 131, a second light-emitting functional portion 132 and a first isolation portion 120; the first light-emitting functional portion 131 is arranged on one side of the substrate 110; the second light-emitting functional portion 132 is arranged on one side of the substrate 110, and the second light-emitting functional portion 132 is arranged adjacent to the first light-emitting functional portion 131; the first isolation portion 120 is used to separate the second light-emitting functional portion 132 from the first light-emitting functional portion 131; the first isolation portion 130 includes a first electrode 122a arranged on the side of the first light-emitting functional portion 131 close to the substrate 110.

[0108] Specifically, the display panel 10 may be an organic light emitting diode display panel (Organic Light Emitting Diode, referred to as OLED), a quantum dot electroluminescent display panel (Quantum Dot Light Emitting Diodes, referred to as QLED), or the like.

[0109] In some examples, the substrate 110 may be an array substrate. Specifically, the substrate 110 may include a substrate (not shown) and a driving circuit layer (not shown) disposed on the substrate. The substrate may be a rigid substrate or a flexible substrate. When the substrate is a rigid substrate, the material of the substrate may be glass or silicon wafer, etc. When the substrate is a flexible substrate, the material of the substrate may be polyimide. The driving circuit layer includes a pixel driving circuit layer, and the pixel driving circuit layer includes a thin film transistor.

[0110] In some examples, the first light-emitting functional unit 131 and the second light-emitting functional unit 132 each include at least a light-emitting layer (EML), and may also include one or more of a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole blocking layer (HBL), and an electron blocking layer (EBL). Alternatively, the first light-emitting functional unit 131 and the second light-emitting functional unit 132 may also be a laminated light-emitting layer, that is, include at least two light-emitting layers and a charge generation layer (CGL) located between each adjacent light-emitting layer.

[0111] The first isolation portion 120 is used to isolate the second light-emitting functional portion 132 from the first light-emitting functional portion 131, so that the water-oxygen lateral transmission path during the etching process can be isolated, and the probability of water-oxygen erosion of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 during the etching process can be reduced, thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10. In addition, the adjacent first light-emitting functional portion 131 and the second light-emitting functional portion 132 can be isolated during the evaporation process, thereby effectively reducing the lateral crosstalk between the first light-emitting functional portion 131 and the second light-emitting functional portion 132, thereby improving the display effect of the display panel 10.

[0112] The first isolation portion 120 includes a first electrode 122a disposed on a side of the first light-emitting functional portion 131 close to the substrate 110. That is to say, the first electrode 122a corresponding to the first light-emitting functional portion 131 is used as a part of the first isolation portion 120. In this way, the area occupied by the first isolation portion 120 can be reduced, which is beneficial to improving the pixel density of the display panel, and further improving the display effect of the display panel.

[0113] The first electrode 122a can be an anode, and the display panel 10 further includes a cathode. Both the anode and the cathode are electrically connected to the pixel driving circuit layer, so that the first light emitting functional unit 131 and the second light emitting functional unit 132 can emit light normally, thereby ensuring the normal use of the display panel 10.

[0114] In summary, in the display panel 10 provided in the embodiment of the present application, the first isolating portion 120 is used to isolate the second light-emitting functional portion 132 from the first light-emitting functional portion 131; the first isolating portion 130 includes a first electrode 122a provided on the side of the first light-emitting functional portion 131 close to the substrate 110. In this way, on the one hand, the water-oxygen lateral transmission path during the etching process can be isolated, and the probability of water-oxygen erosion of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 during the etching process can be reduced, and the probability of lateral crosstalk between the first light-emitting functional portion 131 and the second light-emitting functional portion 132 can be effectively reduced, thereby improving the display effect of the display panel 10 and facilitating the extension of the service life of the display panel 10. On the other hand, the area occupied by the first isolating portion 120 can be reduced, thereby improving the pixel density of the display panel, and further improving the display effect of the display panel 10.

[0115] like Figures 1 to 7 As shown, in one embodiment, the first isolation portion 120 further includes a first isolation body 121, and the first isolation body 121 is disposed on a side of the first electrode 122a close to the substrate 110; the orthographic projection of the first isolation body 121 on the substrate 110 is located within the orthographic projection range of the first electrode 122a on the substrate 110. In a specific example, the end of the first electrode 122a close to the second light-emitting functional portion 132 extends toward the second light-emitting functional portion 132 to protrude from at least a portion of the side wall of the first isolation body 121 close to the second light-emitting functional portion 132.

[0116] Thus, the first isolation portion 120 can form an undercut structure with a "large upper portion and a small lower portion", that is, the first isolation portion 120 near the second light-emitting functional portion has an "eave". In this way, when the first light-emitting functional portion 131 or the second light-emitting functional portion 132 is manufactured by the evaporation process, the first light-emitting functional material layer (corresponding to the film layer of the first light-emitting functional portion 131) or the second light-emitting functional material layer (corresponding to the film layer of the second light-emitting functional portion 132) can be isolated, so that the water-oxygen lateral transmission path during the etching process can be isolated, and the probability of water-oxygen erosion of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 during the etching process can be reduced, so that the display effect of the display panel 10 can be improved and the service life of the display panel 10 can be extended.

[0117] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in one embodiment, the first isolator 121 includes at least one insulating layer. In a specific example, the material of the first isolator 121 can be organic glue.

[0118] Thus, the etching selectivity between the material of the first electrode 122 a and the insulating material can be utilized to form the first isolation portion 120 with an undercut structure, so that the first isolation portion 120 can separate the first light emitting functional portion 131 from the second light emitting functional portion 132 .

[0119] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, in one embodiment, the first insulator 121 is provided with a first through groove 121a penetrating along the thickness direction of the substrate 110, the first through groove 121a is provided with a first conductive connecting portion 121b, and the first electrode 122a is electrically connected to the first conductive connecting portion 121b.

[0120] Thus, the first electrode 122a can be electrically connected to the pixel driving circuit layer through the first conductive connection portion 121b, so that the wiring arrangement of the display area is more optimized.

[0121] like Figure 3 , Figure 6 , Figure 7 As shown, in one embodiment, the first isolation body 121 includes at least one metal layer.

[0122] Thus, the first electrode 122a can be electrically connected to the pixel driving circuit layer below through the first insulator 121, so that the wiring arrangement of the display area is more optimized.

[0123] like Figure 3 , Figure 6 As shown, in one embodiment, the first insulator 121 includes a first metal layer 1211 and a second metal layer 1212 which are stacked, and the second metal layer 1212 is located on a side of the first metal layer 1211 close to the first electrode 122a; the orthographic projection of the first metal layer 1211 on the substrate 110 is located within the orthographic projection range of the second metal layer 1212 on the substrate 110. In a specific example, the first metal layer 1211 may be aluminum, and the second metal layer 1212 may be titanium.

[0124] Thus, the first isolator 121 with an undercut structure can be formed by virtue of the etching selectivity of different metal materials, thereby ensuring that the first isolating portion 120 can isolate the first light-emitting functional portion 131 from the second light-emitting functional portion 132, thereby improving the display effect of the display panel 10. In addition, the resistance of the first isolating portion can be reduced, thereby reducing the power consumption of the display panel.

[0125] like Figure 3 , Figure 6 As shown, in one embodiment, the first electrode 122 a is located on a side of the second metal layer 1212 facing away from the substrate 110 , and the orthographic projection of the first electrode 122 a on the substrate 110 coincides with the orthographic projection of the second metal layer 1212 on the substrate 110 .

[0126] Thus, the first isolation portion 120 can be ensured to have an undercut structure, and can be ensured to be able to separate the first light-emitting functional portion 131 from the second light-emitting functional portion 132 , thereby improving the display effect of the display panel 10 .

[0127] like Figures 1 to 7 As shown, in one embodiment, a first insulating portion 141 is further included. The first insulating portion 141 is disposed on a side of the first electrode 122 a close to the second light-emitting functional portion 132 .

[0128] In this way, the first insulating portion 141 can provide protection for the periphery of the first electrode 122 a , thereby reducing the lateral electrical crosstalk between the first light emitting functional portion 131 and the second light emitting functional portion 132 , and improving the display effect of the display panel 10 .

[0129] like Figures 1 to 7 As shown, in one embodiment, the first insulating portion 141 covers the side wall of the first electrode 122 a close to the second light emitting functional portion 132 .

[0130] Thus, the lateral electrical crosstalk between the first light emitting functional portion 131 and the second light emitting functional portion 132 can be effectively reduced, thereby improving the display effect of the display panel 10 .

[0131] like Figures 1 to 7As shown, in one embodiment, the first insulating portion 141 extends to the surface of the first electrode 122a away from the substrate 110 and defines a first opening 141a; at least a portion of the first light-emitting functional portion 131 is disposed in the first opening 141a.

[0132] Thus, the first insulating portion 141 can provide protection for the periphery of the first light emitting functional portion 131 , thereby reducing lateral electrical crosstalk between the first light emitting functional portion 131 and the second light emitting functional portion 132 , and improving the display effect of the display panel 10 .

[0133] like Figures 1 to 3 As shown, in one embodiment, a first material layer 151 is disposed on a side wall of the first insulating portion 141 close to the second light-emitting functional portion 132 .

[0134] Thus, during the etching process, the first material layer 151 and the second light-emitting functional part 132 are protected by the photoresist, so that the second light-emitting functional part 132 can be protected laterally, the etching amount and etching time can be reduced, and the probability of water and oxygen corrosion of the second light-emitting functional part 132 during the etching process can be effectively reduced, thereby improving the display effect of the display panel 10. In addition, the first insulating part 141 separates the first material layer 151 from the first electrode 122a, so as to avoid crosstalk.

[0135] like Figures 1 to 3 As shown, in one embodiment, the first material layer 151 is connected to the first light emitting functional portion 131 .

[0136] Thus, during the etching process, the first material layer 151 and the first light-emitting functional unit 131 are protected by the photoresist, so that the first light-emitting functional unit 131 can be protected laterally, the etching amount and etching time can be reduced, and the probability of water and oxygen corrosion of the first light-emitting functional unit 131 during the etching process can be effectively reduced, thereby improving the display effect of the display panel 10. In addition, the first insulating part 141 separates the first material layer 151 from the first electrode 122a, and even if the first material layer 151 is connected to the first light-emitting functional unit 131, it will not affect the normal light emission of the first light-emitting functional unit 131, thereby ensuring the display effect of the display panel 10.

[0137] like Figures 1 to 3 As shown, in one embodiment, the first material layer 151 and the second light emitting functional portion 132 are made of the same material.

[0138] Thus, the first material layer 151 and the second light-emitting functional part 132 can be simultaneously manufactured by the evaporation process. During the etching process, the first material layer 151 and the second light-emitting functional part 132 are protected by the photoresist, so that the second light-emitting functional part 132 can be protected laterally, the etching amount and etching time can be reduced, and the probability of water and oxygen corrosion of the second light-emitting functional part 132 during the etching process can be effectively reduced, thereby improving the display effect of the display panel 10.

[0139] like Fig.11 As shown, in one embodiment, the orthographic projection of the first isolation portion 120 on the substrate 110 is in a grid shape.

[0140] like Fig.11 As shown, in one embodiment, the first electrode 122a is in a grid shape, the first light-emitting functional portion 131 covers the first electrode 122a; and the second light-emitting functional portion 132 is located in the mesh holes of the grid shape.

[0141] Thus, the first isolation portion 120 can separate any adjacent first light-emitting functional portion 131 and second light-emitting functional portion 132, effectively reducing the probability of water and oxygen corrosion of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 during the etching process, and effectively reducing the lateral crosstalk between the first light-emitting functional portion 131 and the second light-emitting functional portion 132, thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10.

[0142] like Figure 8 As shown, in one embodiment, the orthographic projection of the first isolation portion 120 on the substrate is in the shape of a strip.

[0143] like Figure 8 As shown, in a specific example, the first electrode 122 a is in a strip shape, and the first light-emitting functional portion 131 is in a strip shape and extends along a first direction X; the first direction X is an extending direction of the first electrode 122 a.

[0144] like Figure 8 As shown, in a specific example, the second light emitting functional portion 132 is strip-shaped and extends along the first direction X, the second light emitting functional portion 132 and the first light emitting functional portion 131 are spaced apart along the second direction Y, and the first direction X intersects with the second direction Y and is perpendicular to the thickness direction of the substrate 110.

[0145] Thus, the first isolation portion 120 can separate the first light emitting functional portion 131 from the second light emitting functional portion 132 , thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10 .

[0146] like Figures 1 to 7As shown, in one embodiment, a second electrode 161 is further included, and the second electrode 161 is disposed on a side of the second light-emitting functional portion 132 close to the substrate 110. In a specific example, the second electrode 161 can be an anode.

[0147] like Figures 1 to 7 As shown, in one embodiment, the second electrode 161 and the first electrode 122a are disposed in the same layer or in different layers, which can be designed according to process requirements.

[0148] like Figures 1 to 7 As shown, in one embodiment, the orthographic projection of the second electrode 161 on the substrate 110 does not overlap with the orthographic projection of the first electrode 122 a on the substrate 110 .

[0149] Thus, an effective distance can be maintained between the first electrode 122a and the second electrode 161, and the probability of tip discharge between the first electrode 122a and the second electrode 161 can be reduced, thereby extending the service life of the first light-emitting functional portion 131 and the second light-emitting functional portion 132, thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10.

[0150] like Figures 4 to 7 As shown, in one embodiment, the second electrode 161 is arranged in the same layer as the first electrode 122a; the display panel 10 also includes a second isolation portion 160, the second isolation portion 160 includes the second electrode 160, the second isolation portion 160 also includes a second isolation body 162, and the second isolation body 162 is located on the side of the second electrode 161 away from the second light-emitting functional portion 132; the orthographic projection of the second isolation body 162 on the substrate is located within the orthographic projection range of the second electrode 161 on the substrate.

[0151] Thus, an undercut structure with a "large top and small bottom" can be formed between the second electrode 161 and the second insulator 162, that is, the second isolating portion 160 has an undercut structure with a "large top and small bottom". In this way, when the second light-emitting functional portion 132 is manufactured by the evaporation process, the second light-emitting functional material layer (corresponding to the film layer of the second light-emitting functional portion 132) can be isolated, thereby isolating the lateral water and oxygen transmission path during the etching process, reducing the probability of water and oxygen erosion of the second light-emitting functional portion 132 during the etching process, thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10.

[0152] like Figures 4 to 7 As shown, in one embodiment, the first isolating body 121 and the second isolating body 162 are spaced apart from each other.

[0153] Therefore, the first light-emitting functional portion 131 is separated below the first electrode 122a, and the second light-emitting functional portion 132 is separated below the second electrode 161. This, on the one hand, is conducive to the production of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 using a photolithography process; on the other hand, it can effectively reduce the probability of water and oxygen corrosion of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 during the etching process, thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10.

[0154] like Figures 4 to 7 As shown, in one embodiment, the second insulator 162 is disposed at the same layer as at least a portion of the first insulator 121 .

[0155] Therefore, that is to say, at least part of the second insulator 162 and the first insulator 121 are manufactured by patterning the same film layer, thus reducing the manufacturing process steps of the display panel and improving the manufacturing efficiency of the display panel.

[0156] like Fig. 9 As shown, in one embodiment, the orthographic projection of the second insulator 162 on the substrate 110 is arranged in blocks at intervals; the second electrodes 161 are arranged in blocks at intervals, and the second light-emitting functional parts 132 are arranged in blocks at intervals.

[0157] Thus, the second light-emitting functional portion 132 can be isolated below the second electrode 161 , reducing the probability of water and oxygen corrosion of the second light-emitting functional portion 132 during the etching process, thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10 .

[0158] like Fig. 9 As shown, in one embodiment, the orthographic projection of the first insulator 121 on the substrate 110 is arranged in blocks; the first electrodes 122a are arranged in blocks, and the first light-emitting functional parts 131 are arranged in blocks; the first light-emitting functional parts 131 and the second light-emitting functional parts 132 are arranged in blocks.

[0159] Therefore, the first light-emitting functional portion 131 is separated below the first electrode 122a, and the second light-emitting functional portion 132 is separated below the second electrode 161. This, on the one hand, is conducive to the production of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 using a photolithography process; on the other hand, it can effectively reduce the probability of water and oxygen corrosion of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 during the etching process, thereby improving the display effect of the display panel 10 and extending the service life of the display panel 10.

[0160] like Figure 1As shown, in one embodiment, the first electrode 122a and the second electrode 161 are arranged in different layers, and a first distance H1 is formed between the side of the first electrode 122a facing away from the substrate 110 and the substrate 110, and a second distance H2 is formed between the side of the second electrode 161 facing away from the substrate 110 and the substrate 110; the first distance H1 is greater than the second distance H2.

[0161] Thus, the first electrode 122a and the second electrode 161 have an oblique distance M, so that as long as the oblique distance M between the first electrode 122a and the second electrode 161 is greater than or equal to the effective spacing, the tip discharge between the first electrode 122a and the second electrode 161 can be avoided, and the horizontal distance N between the first electrode 122a and the second electrode 161 is a component of the oblique distance M, so that the horizontal distance between the first electrode 122a and the second electrode 161 can be shortened, which is beneficial to increase the effective light-emitting area of ​​the first light-emitting functional portion 131, improve the life of the first light-emitting functional portion 131, and further extend the service life of the display panel 10. In addition, when the effective light-emitting area of ​​the first light-emitting functional portion 131 remains unchanged, the area occupied by the first light-emitting functional portion 131 can be reduced, so that the pixel density of the display panel 10 can be increased, and the display effect of the display panel 10 can be improved.

[0162] like Figure 4 , Figure 5 As shown, in one embodiment, the first electrode 122a and the second electrode 161 are arranged in the same layer, and a first distance H1 is formed between the side of the first electrode 122a facing away from the substrate 110 and the substrate 110, and a second distance H2 is formed between the side of the second electrode 161 facing away from the substrate 110 and the substrate 110; the first distance H1 is greater than or equal to the second distance H2.

[0163] Thus, the first electrode 122a and the second electrode 161 are manufactured by patterning the same film layer, thus reducing the manufacturing process steps of the display panel 10 and improving the manufacturing efficiency of the display panel 10. When the first distance H1 is greater than the second distance H2, it is beneficial to increase the effective light emitting area of ​​the first light emitting functional portion 131, improve the life of the first light emitting functional portion 131, and further extend the service life of the display panel 10. In addition, when the effective light emitting area of ​​the first light emitting functional portion 131 remains unchanged, the area occupied by the first light emitting functional portion 131 can be reduced, thereby improving the pixel density of the display panel 10 and improving the display effect of the display panel 10.

[0164] like Figure 2 , Figure 5 , Figure 7 As shown, in one embodiment, a first insulating layer 171 is further included. The first insulating layer 171 is disposed on a side of the first insulator 121 away from the first electrode 122a.

[0165] Thus, the first insulating layer 171 can play a role in padding the first isolation portion 120, thereby increasing the first distance H1 between the side of the first electrode 122a away from the substrate 110 and the substrate 110, so that the first distance H1 is greater than the second distance H2, which is conducive to increasing the effective light-emitting area of ​​the first light-emitting functional portion 131, improving the life of the first light-emitting functional portion 131, and further extending the service life of the display panel 10. In addition, when the effective light-emitting area of ​​the first light-emitting functional portion 131 remains unchanged, the area occupied by the first light-emitting functional portion 131 can be reduced, thereby increasing the pixel density of the display panel 10 and improving the display effect of the display panel 10.

[0166] like Figure 2 , Figure 5 , Figure 7 As shown, in one embodiment, the orthographic projection of the first isolation portion 120 on the substrate 110 is located within the orthographic projection range of the first insulating layer 171 on the substrate 110 .

[0167] Therefore, the first insulating layer 171 can provide protection for the substrate 110 during the etching process, thereby reducing the probability of damage to the substrate 110 during the etching process and improving the reliability of the display panel 10 .

[0168] like Figure 2 , Figure 5 , Figure 7 As shown, in one embodiment, a second through-groove 171 a penetrating along the thickness direction of the substrate 110 is disposed on the first insulating layer 171 , and a second conductive connecting portion 171 b is disposed in the second through-groove 171 a .

[0169] Thus, the electrical connection between the first electrode 122a and the pixel driving circuit layer below can be facilitated, thereby optimizing the wiring arrangement of the display area of ​​the display panel.

[0170] like Figures 1 to 7 As shown, in one embodiment, a second insulating portion 142 is further included. The second insulating portion 142 is disposed on a side of the second electrode 161 close to the first light-emitting functional portion 131 .

[0171] In this way, the second insulating portion 142 can provide protection around the second electrode 161 , thereby reducing lateral electrical crosstalk between the first light-emitting functional portion 131 and the second light-emitting functional portion 132 and between the first electrode 122 a and the second electrode 161 , thereby improving the display effect of the display panel 10 .

[0172] like Figures 1 to 7 As shown, in one embodiment, the second insulating portion 142 covers the side wall of the second electrode 161 close to the first light emitting functional portion 131 .

[0173] Thus, the lateral electrical crosstalk between the first light emitting functional portion 131 and the second light emitting functional portion 132 and between the first electrode 122 a and the second electrode 161 can be effectively reduced, thereby improving the display effect of the display panel 10 .

[0174] like Figures 1 to 7 As shown, in one embodiment, the second insulating portion 142 extends to the surface of the second electrode 161 away from the substrate 110 and defines a second opening 142 a ; at least a portion of the second light emitting functional portion 132 is disposed in the second opening 142 a .

[0175] Thus, the second insulating portion 142 can provide protection for the periphery of the second light emitting functional portion 132 , thereby reducing lateral electrical crosstalk between the first light emitting functional portion 131 and the second light emitting functional portion 132 , and improving the display effect of the display panel 10 .

[0176] like Figures 1 to 7 As shown, in one embodiment, the second light emitting functional portion 132 extends to a side of the second insulating portion 142 close to the first light emitting functional portion 131 .

[0177] Therefore, during the etching process, the second light-emitting functional portion 132 is protected by the photoresist, so that the second light-emitting functional portion 132 can be protected laterally, the etching amount and etching time can be reduced, and the probability of water and oxygen corrosion of the second light-emitting functional portion 132 during the etching process can be effectively reduced, thereby improving the display effect of the display panel 10.

[0178] like Figures 1 to 7 As shown, in one of the embodiments, it further includes a light-emitting material layer 181 , which is disposed on one side of the substrate 110 ; the light-emitting material layer 181 is located between the second electrode 161 and the first insulator 121 .

[0179] Therefore, during the etching process, the photoresist is used to protect the light-emitting material layer 181, so that the first light-emitting functional part 131 and the second light-emitting functional part 132 can be protected laterally, reducing the etching amount and etching time, thereby effectively reducing the probability of water and oxygen erosion of the first light-emitting functional part 131 and the second light-emitting functional part 132 during the etching process, thereby improving the display effect of the display panel 10.

[0180] like Figures 1 to 7 As shown, in one embodiment, a third insulating portion 143 is further included. The third insulating portion 143 is connected to the second insulating portion 142 , and the third insulating portion 143 covers at least a portion of the side wall of the first insulator 121 close to the second electrode 161 .

[0181] Thus, the lateral electrical crosstalk between the first light emitting functional portion 131 and the second light emitting functional portion 132 and between the first electrode 122 a and the second electrode 161 can be effectively reduced, thereby improving the display effect of the display panel 10 .

[0182] like Figures 1 to 3 In one of the embodiments shown, the light emitting material layer 181 is made of the same material as the second light emitting functional portion 132 and is connected to the second light emitting functional portion 132 .

[0183] like Figures 4 to 7 As shown, in one embodiment, it also includes a third insulating portion 143, which covers at least a portion of the side wall of the second insulator 162 close to the first insulator 121; the third insulating portion 143 covers at least a portion of the side wall of the first insulator 121 close to the second electrode 161.

[0184] Thus, the lateral electrical crosstalk between the first electrode 122 a and the second electrode 161 can be effectively reduced, thereby improving the display effect of the display panel 10 .

[0185] like Figure 6 As shown, in one embodiment, the light-emitting material layer 181 includes a first sublayer 1811 and a second sublayer 1812 . The first sublayer 1811 is made of the same material as the first light-emitting functional portion 131 , and the second sublayer 1812 is made of the same material as the second light-emitting functional portion 132 .

[0186] Thus, that is to say, the first sublayer 1811 and the first light-emitting functional unit 131 are formed synchronously, and the second sublayer 1812 and the second light-emitting functional unit 132 are formed synchronously. During the etching process, the light-emitting material layer 181 is protected by the photoresist so that the light-emitting material layer 181 is retained, thereby protecting the first light-emitting functional unit 131 and the second light-emitting functional unit 132 laterally, reducing the etching amount and etching time, thereby effectively reducing the probability of water and oxygen erosion of the first light-emitting functional unit 131 and the second light-emitting functional unit 132 during the etching process, and improving the display effect of the display panel 10.

[0187] like Figures 1 to 3 As shown, in one embodiment, a second insulating layer 191 is further included. The second insulating layer 191 is disposed on a side of the light emitting material layer 181 away from the substrate. The second insulating layer 191 is in contact with a surface of the first electrode 122 a close to the substrate 110 .

[0188] Therefore, the second insulating layer 191 can provide insulating protection for the surface of the first electrode 122a close to the substrate 110 to prevent subsequent film layers from being connected to the first electrode 122a and affecting the display; in addition, the second insulating layer 191 can fill the undercut area between the first electrode 122a and the first insulator 121, which is beneficial to the film formation continuity of subsequent film layers.

[0189] like Figures 4 to 7 As shown, in one embodiment, the second insulating layer 191 covers the light emitting material layer 181 , and the second insulating layer 191 is in contact with a surface of the second electrode 161 that is close to the substrate 110 .

[0190] Therefore, the second insulating layer 191 can provide insulating protection for the surface of the second electrode 161 close to the substrate 110 to prevent subsequent film layers from being connected to the second electrode 161 and affecting the display; in addition, the second insulating layer 191 can fill the undercut area between the second electrode 161 and the second insulator 162, which is beneficial to the film formation continuity of subsequent film layers.

[0191] like Figures 1 to 7 As shown, in one embodiment, a third electrode layer 201 is further included; the third electrode layer 201 is disposed on a side of the first light-emitting functional portion 131 away from the substrate 110 and a side of the second light-emitting functional portion 132 away from the substrate 110.

[0196] In one embodiment, the first sub-light emitting functional portion 1321 , the second sub-light emitting functional portion 1322 and the first light emitting functional portion 131 are respectively used to emit lights of different colors.

[0197] In a specific example, the first sub-light emitting functional unit 1321 is used to emit one of red light and green light; the second sub-light emitting functional unit 1322 is used to emit the other of red light and green light; and the first light emitting functional unit 131 is used to emit blue light.

[0198] Second, see Fig.11 , the present application embodiment provides a method for manufacturing a display panel, comprising:

[0199] S10, providing a substrate 110;

[0200] S20, forming a first isolation portion 120, a first light-emitting functional portion 131 and a second light-emitting functional portion 132 on one side of the substrate 110; the first light-emitting functional portion 131 is arranged on one side of the substrate 110; the second light-emitting functional portion 132 is arranged adjacent to the first light-emitting functional portion 131; the first isolation portion 120 is used to separate the second light-emitting functional portion 132 from the first light-emitting functional portion 131; the first isolation portion 120 includes a first electrode 122a arranged on the side of the first light-emitting functional portion 131 close to the substrate 110.

[0201] The manufacturing method of the display panel provided in the embodiment of the present application forms a first isolation part 120, a first light-emitting functional part 131 and a second light-emitting functional part 132 on one side of the substrate 110; the first light-emitting functional part 131 is arranged on one side of the substrate 110; the second light-emitting functional part 132 is arranged adjacent to the first light-emitting functional part 131; the first isolation part 120 is used to isolate the second light-emitting functional part 132 from the first light-emitting functional part 131; the first isolation part 120 includes a first electrode 122a arranged on the side of the first light-emitting functional part 131 close to the substrate 110; in this way, on the one hand, the lateral transmission path of water and oxygen during the etching process can be isolated, and the probability of water and oxygen erosion of the first light-emitting functional part 131 and the second light-emitting functional part 132 during the etching process can be reduced, and the probability of lateral crosstalk between the first light-emitting functional part 131 and the second light-emitting functional part 132 can be effectively reduced, thereby improving the display effect of the display panel 10 and helping to extend the service life of the display panel 10. On the other hand, the area occupied by the first isolation portion 120 can be reduced, so that the pixel density of the display panel 10 can be increased, and further the display effect of the display panel 10 can be improved.

[0202] like Fig.12 As shown, in one embodiment, S20, a first isolation portion 120, a first light-emitting functional portion 131 and a second light-emitting functional portion 132 are formed on one side of the substrate 110, including:

[0203] S210, forming a first isolation body 121 on one side of the substrate 110;

[0204] S220, forming a first electrode 122a and a second electrode 161 on one side of the substrate 110, wherein the first electrode 122a is located on a side of the first isolating body 121 away from the substrate 110, and the orthographic projection of the first isolating body 121 on the substrate 110 is located within the orthographic projection range of the first electrode 122a on the substrate 110, so as to define a first isolating portion 120; the second electrode 161 is located on one side of the substrate 110;

[0205] S230, forming a second light-emitting functional portion 132 on a side of the second electrode 161 away from the substrate 110;

[0206] S240 , forming a first light-emitting functional portion 131 on a side of the first electrode 122 a away from the substrate 110 .

[0207] Thus, a first isolation portion 120 with an undercut structure can be formed, so that the first isolation portion 120 can separate the first light-emitting functional portion 131 from the second light-emitting functional portion 132. In addition, the first distance H1 between the side of the first electrode 122a away from the substrate 110 and the substrate 110 can be greater than the second distance H2 between the side of the second electrode 161 away from the substrate 110 and the substrate 110; in this way, it is beneficial to increase the effective light-emitting area of ​​the first light-emitting functional portion 131, improve the life of the first light-emitting functional portion 131, and further extend the service life of the display panel 10. In addition, when the effective light-emitting area of ​​the first light-emitting functional portion 131 remains unchanged, the area occupied by the first light-emitting functional portion 131 can be reduced, so that the pixel density of the display panel 10 can be increased, and the display effect of the display panel 10 can be improved.

[0208] like Fig.13 As shown, in one embodiment, S220, a first electrode 122a and a second electrode 161 are formed on one side of the substrate 110, the first electrode 122a is located on the side of the first isolator 121 away from the substrate 110, and the orthographic projection of the first isolator 121 on the substrate 110 is located within the orthographic projection range of the first electrode 122a on the substrate 110 to define the first isolation portion 120, and the second electrode 161 is located on one side of the substrate 110, including:

[0209] S221a, forming a second electrode material layer on one side of the substrate 110, and patterning the second electrode material layer to obtain a second electrode 161 located on one side of the substrate 110;

[0211] Thus, the first electrode 122a and the second electrode 161 are arranged in different layers, so that the first electrode 122a has a first distance H1 from the substrate 110 that is greater than the second distance H2 from the substrate 110 that is greater than the second distance H2 from the substrate 110 that is greater than the second distance H2 from the substrate 110 that is greater than the second distance H2 from the substrate 110 that is greater than the second distance H2 from the substrate 110 that is greater than the second distance H1 ...1

[0212] like Fig.14 As shown, in one embodiment, S220, a first electrode 122a and a second electrode 161 are formed on one side of the substrate 110, the first electrode 122a is located on the side of the first isolator 121 away from the substrate 110, and the orthographic projection of the first isolator 121 on the substrate 110 is located within the orthographic projection range of the first electrode 122a on the substrate 110 to define the first isolation portion 120, and the second electrode 161 is located on one side of the substrate 110, including:

[0213] S221b, forming an electrode material layer on the side of the first insulator 121 away from the substrate 110, and composing the third electrode material layer to obtain a first electrode 122a and a second electrode 161; the first electrode 122a is located on the side of the first insulator 121 away from the substrate 110, and the orthographic projection of the first insulator 121 on the substrate 110 is located within the range of the orthographic projection of the first electrode 122a on the substrate 110 to define the first isolation portion 120; the second electrode 161 is located on one side of the substrate 110.

[0214] Thus, the first electrode 122a and the second electrode 161 are arranged in the same layer, so that the first distance H1 between the side of the first electrode 122a facing away from the substrate 110 and the substrate 110 is greater than or equal to the second distance H2 between the side of the second electrode 161 facing away from the substrate 110 and the substrate 110.

[0215] like Fig.15 As shown, in one embodiment, S20, a first isolation portion 120, a first light-emitting functional portion 131 and a second light-emitting functional portion 132 are formed on one side of the substrate 110, including:

[0219] S240a, forming a first light-emitting functional portion 131 on a side of the first electrode 122a away from the substrate 110.

[0220] Thus, the first isolation portion 120 and the second isolation portion can be manufactured simultaneously, thereby simplifying the manufacturing process of the display panel 10 and improving the manufacturing efficiency of the display panel 10 .

[0221] Third, see 1 to Figure 7 The embodiment of the present application provides a display panel 10, including a substrate 110, a first light-emitting functional portion 131, a first isolation portion 120 and a second light-emitting functional portion 132; the first light-emitting functional portion 131 is arranged on one side of the substrate 110; the first isolation portion 120 is arranged on a side of the substrate 110 close to the first light-emitting functional portion 131, the first isolation portion 120 includes a first isolation body 121 and a first blocking portion 122b arranged on a side of the first isolation body 121 close to the first light-emitting functional portion 131; the orthographic projection of the first isolation body 121 on the substrate 110 is located within the orthographic projection range of the first blocking portion 122b on the substrate 110; the first blocking portion 122b is reused as a first electrode 122a; the first electrode 122a is located on a side of the first light-emitting functional portion 131 close to the substrate 110; the second light-emitting functional portion 132 is arranged on one side of the substrate 110, and the second light-emitting functional portion 132 is arranged adjacent to the first light-emitting functional portion 131.

[0222] In the display panel 10 provided by the embodiment of the present application, the orthographic projection of the first isolator 121 of the first isolating portion 120 on the substrate 110 is located within the orthographic projection range of the first blocking portion 122b on the substrate 110; the first blocking portion is reused as the first electrode 122a. In this way, on the one hand, the first isolating portion 120 can isolate the second light-emitting functional portion 132 from the first light-emitting functional portion 131, so that the lateral transmission path of water and oxygen during the etching process is isolated, thereby reducing the probability of water and oxygen erosion of the first light-emitting functional portion 131 and the second light-emitting functional portion 132 during the etching process, and effectively reducing the probability of lateral crosstalk between the first light-emitting functional portion 131 and the second light-emitting functional portion 132, thereby improving the display effect of the display panel 10 and facilitating the extension of the service life of the display panel 10. On the other hand, the first blocking portion 122b is reused as the first electrode 122a, which is located on the side of the first light-emitting functional portion 131 close to the substrate 110, which can reduce the area occupied by the first isolation portion 120, thereby increasing the pixel density of the display panel 10 and further improving the display effect of the display panel 10.
