[0010] Flat display devices based on organic light emitting diodes and light emitting diodes have the advantages of high image quality, power saving, thinness, and wide range of applications, and are widely used in various consumer electronic products such as mobile phones, televisions, notebook computers, and desktop computers, becoming the mainstream in display devices. However, the performance of current OLED display products needs to be improved.

[0011] In order to solve the above problems, embodiments of the present application provide a display panel and a display device, and each embodiment of the display panel and the display device will be described below with reference to the drawings.

[0012] FIG. 1 is a structural schematic diagram of a display panel 10 according to an embodiment of the present application, and FIG. 2 is a partial cross-sectional view of the display panel 10 according to the embodiment of the present application, in which the X direction in the figure is the thickness direction of the display panel 10, the Y direction in the figure is the first direction, and the Z direction in the figure is the second direction, where the first direction Y and the second direction Z intersect with the thickness direction X two by two.

[0013] As shown in Figures 1 and 2, an embodiment of a first aspect of the present application provides a display panel 10, which may be an Organic Light Emitting Diode (OLED) display panel.

[0014] As shown in Figures 1 and 2, an embodiment of the first aspect of the present application provides a display panel 10, which has a display area AA and a non-display area NA, and the display panel 10 includes an array substrate 100, an emitting layer 700 provided on the array substrate 100 and including a plurality of light-emitting units 710, an isolation structure 500 located in the display area AA, provided on the array substrate 100 and having a plurality of isolation openings 500a, the light-emitting units 710 being located in the isolation openings 500a, and a first shielding structure 600 located in the non-display area NA and installed in the same layer as at least a portion of the isolation structure 500, and at least a portion of a touch assembly 900 is located on the side of the first shielding structure 600 away from the array substrate 100.

[0015] In the display panel 10 of the embodiment of the present application, the display panel 10 has a display area AA and a non-display area NA, and includes an array substrate 100, an emission layer 700, an isolation structure 500, a first shielding structure 600, and a touch assembly 900, where the isolation structure 500 is provided on the array substrate 100 in the display area AA and has a plurality of isolation openings 500a, and the emission units 710 of the emission layer 700 are provided in the isolation openings 500a, so that the isolation structure 500 can partition the sub-pixels of the display panel 10.

[0016] By arranging the first shielding structure 600 in the non-display area NA and at least a portion of the touch assembly 900 to be located on the side of the first shielding structure 600 away from the array substrate 100, the first shielding structure 600 can effectively restrict the transmission of signals in the array substrate 100 to the touch assembly 900, effectively reduce the mutual interference between the signals in the array substrate 100 and the touch signals in the touch assembly 900, and effectively improve the operation reliability of the display panel 10. Furthermore, by providing the first shielding structure 600 and disposing it in the same layer as at least a portion of the isolation structure 500, the first shielding structure 600 can be manufactured in the same process step as the isolation structure 500, so that the provision of the first shielding structure 600 can restrict the mutual interference between the touch signals and other signals in the display panel 10, and can simplify the manufacturing process of the display panel 10 and improve the manufacturing efficiency of the display panel 10.

[0017] There are a number of ways to install the array substrate 100. The array substrate 100 may include, for example, a base 110 and a driving circuit 170 provided on the base 110. Alternatively, the array substrate may include a first insulating layer 120, a second insulating layer 130, and a third insulating layer 140 that are stacked. Exemplarily, the driving circuit 170 may include a transistor 171, a storage capacitor 172, and a driving signal line for connecting each device. The transistor 171 includes a semiconductor, a gate electrode 171a, a source electrode 171b, and a drain electrode 171c. The storage capacitor 172 includes a first plate 172a and a second plate 172b. As an example, the gate electrode 171a and the first plate 172a may be located on the first insulating layer 120, the second plate 172b may be located on the second insulating layer 130, and the source electrode 171b and the drain electrode 171c may be located on the third insulating layer 140.

[0018] The touch assembly 900 may include touch electrodes and signal lines connected to the touch electrodes, such as a touch ground signal line, a touch driving signal line, a touch receiving signal line, and the like.

[0019] In some embodiments of the present application, the isolation structure 500 may be disposed in the display area AA of the display panel 10, and the first shielding structure 600 may be disposed in the non-display area NA of the display panel 10, such that the touch assembly 900 disposed in the non-display area NA and located on the side of the first shielding structure 600 away from the array substrate 100 is less likely to interfere with other signals in the display panel 10 due to the shielding of the first shielding structure 600. For example, the first shielding structure 600 can shield the driving signal of the driving circuit 170 disposed in the non-display area NA, so that the touch signal of the touch assembly 900 is less likely to interfere with the driving signal of the driving circuit 170, and the operation reliability of the display panel 10 can be improved.

[0020] Optionally, the orthogonal projection of the touch assembly 900 located in the non-display area NA on the array substrate 100 is arranged to overlap with the orthogonal projection of the first shielding structure 600 on the array substrate 100. Optionally, the orthogonal projection of the driving circuit 170 located in the non-display area NA on the array substrate 100 is arranged to overlap with the orthogonal projection of the first shielding structure 600 on the array substrate 100. In these optional embodiments, the relative positions of the first shielding structure 600, the touch assembly 900, and the driving circuit 170 are reasonably arranged to improve the shielding effect of the first shielding structure 600, and improve the effect of the first shielding structure 600 in restricting mutual interference between touch signals and driving signals in the display panel 10.

[0021] Alternatively, the isolation structure 500 and the first shielding structure 600 are disposed in the same layer and are both integral structures, so that the first shielding structure 600 can be manufactured together with the isolation structure 500 in the same process step, thereby simplifying the manufacturing process of the display panel 10 and improving the manufacturing efficiency of the display panel 10.

[0022] As shown in FIG. 2, optionally, the isolation structure 500 and the first shielding structure 600 both include a first end 10a facing the array substrate 100 and a second end 10b away from the array substrate 100, and the orthogonal projection of the first end 10a of the isolation structure 500 on the array substrate 100 is located within the orthogonal projection of the second end 10b of the isolation structure 500 on the array substrate 100, and the orthogonal projection of the first end 10a of the first shielding structure 600 on the array substrate 100 is located within the orthogonal projection of the second end 10b of the first shielding structure 600 on the array substrate 100.

[0023] Optionally, in the direction away from the array substrate 100, the distance between the surfaces of the isolation openings 500a on either side of the isolation structure 500 may gradually increase such that the orthogonal projection of the first end 10a of the isolation structure 500 on the array substrate 100 lies within the orthogonal projection of the second end 10b on the array substrate 100.

[0024] In these optional embodiments, the orthogonal projection of the first end 10a of the isolation structure 500 on the array substrate 100 is located within the orthogonal projection of the second end 10b of the isolation structure 500 on the array substrate 100. Therefore, when depositing the light-emitting layer 700 of the display panel 10, the second end 10b can shield at least a portion of the material used to manufacture the light-emitting layer 700, so as to block the light-emitting layer 700 between adjacent subpixels, and a plurality of spaced-apart light-emitting units 710 can be easily formed. This eliminates the need to install a highly accurate mask plate when depositing the light-emitting layer 700 of the display panel 10, for example, eliminates the need to install a high-precision metal mask (Fine Metal Mask, FMM) when depositing the light-emitting layer 700, thereby reducing the manufacturing cost of the display panel 10.

[0025] FIG. 3 is a partial cross-sectional view of a display panel 10 according to another embodiment of the present application, and FIG. 4 is a partial cross-sectional view of a display panel 10 according to another embodiment of the present application.

[0026] As shown in Figures 3 and 4, optionally, the isolation structure 500 includes a first isolation portion 510 and a second isolation portion 520 provided on a side of the first isolation portion 510 away from the array substrate 100, and the orthogonal projection of the first isolation portion 510 on the array substrate 100 is located within the orthogonal projection of the second isolation portion 520 on the array substrate 100.

[0027] The isolation structure 500 includes a first isolation portion 510 and a second isolation portion 520 arranged on a side of the first isolation portion 510 away from the array substrate 100, and is arranged such that the orthogonal projection of the first isolation portion 510 on the array substrate 100 is located within the orthogonal projection of the second isolation portion 520 on the array substrate 100. By so doing, when depositing the light-emitting layer 700 and the second electrode layer 800 of the display panel 10, the second isolation portion 520 can shield at least a portion of the material for manufacturing the light-emitting layer 700 and the material for manufacturing the second electrode layer 800, so as to block the light-emitting layer 700 and the second electrode layer 800 between adjacent subpixels, and thus the light-emitting units 710 and the second electrodes 810 arranged at multiple intervals can be easily formed. This eliminates the need to install a highly accurate mask plate when depositing the light-emitting layer 700 and the second electrode layer 800 of the display panel 10; for example, it eliminates the need to install a highly accurate metal mask plate when depositing the light-emitting layer 700 and the second electrode layer 800, thereby reducing the manufacturing cost of the display panel 10.

[0028] Optionally, the display panel 10 may further include a pixel defining layer 400 provided on one side of the array substrate 100, the pixel defining layer 400 including a pixel defining portion 410 and a plurality of pixel openings 420 opened in the pixel defining portion 410, and the pixel defining portion 410 may define sub-pixels in the display panel 10. Optionally, the orthogonal projection of the pixel opening 420 on the array substrate 100 may be located within the orthogonal projection of the isolation opening 500a on the array substrate 100.

[0029] 3, in some embodiments, the pixel limiting portion 410 may have an accommodating groove 410a recessed toward the array substrate 100, and the isolation structure 500 may be disposed in the accommodating groove 410a, so that the isolation structure 500 is less likely to have an excessively large height compared to the array substrate 100, and the thickness of the display panel 10 may be suitably reduced. Optionally, the first shielding structure 600 disposed in the same layer as the isolation structure 500 may be disposed in the accommodating groove 410a of the pixel limiting portion 410 located in the non-display area NA.

[0030] 1 and 4, in some other embodiments, the isolation structure 500 may be directly disposed on the side of the pixel limiting portion 410 away from the array substrate 100. Optionally, the pixel opening 420 may be provided only in the non-display area NA as shown in Fig. 1, or alternatively, the pixel opening 420 may be provided in both the display area AA and the non-display area NA as shown in Fig. 4.

[0031] For convenience of explanation, the following embodiments will be described taking as an example an isolation structure 500 disposed on a side of the pixel limiting portion 410 away from the array substrate 100. Alternatively, the first shielding structure 600 disposed in the same layer as the isolation structure 500 may be disposed on a side of the pixel limiting portion 410 away from the array substrate 100.

[0032] In some optional embodiments, the display panel 10 further includes a first electrode layer 300 disposed on one side of the array substrate 100, the first electrode layer 300 including a plurality of first electrodes 310 disposed within the isolation openings 500a. Optionally, the first electrodes 310 are located on a side where the light-emitting units 710 face the array substrate 100.

[0033] Optionally, the display panel 10 further includes a second electrode layer 800 disposed on one side of the array substrate 100, the second electrode layer 800 including a plurality of second electrodes 810 disposed in the isolation openings 500a. Optionally, the second electrodes 810 are located on a side of the array substrate 100 where the light emitting units 710 are spaced apart from the array substrate 100.

[0034] Optionally, the light emitting layer 700 is located between the first electrode layer 300 and the second electrode layer 800. Here, the light emitting unit 710 may include a hole inject layer (HIL), a hole transport layer (HTL), a light emitting structure, an electron inject layer (EIL) and an electron transport layer (ETL).

[0035] Alternatively, the first electrode layer 300 and the second electrode layer 800 may be pixel electrode layers, with one of the first electrode layer 300 and the second electrode layer 800 functioning as an anode and the other functioning as a cathode to drive the light emitting unit 710 to emit light. In the embodiment of the present application, an example will be described in which the first electrode layer 300 is the anode of the display panel 10 and the second electrode layer 800 is the cathode of the display panel 10.

[0036] Alternatively, the second electrode layer 800 and the light-emitting layer 700 may be disposed in the display area AA of the display panel 10, so that water vapor does not easily penetrate from the non-display area NA into the path located in the second electrode layer 800 and the light-emitting layer 700 of the display area AA, and the water vapor is less likely to propagate through the display panel 10 via the second electrode layer 800 and the light-emitting layer 700, thereby favorably improving the operating reliability of the display panel 10.

[0037] In some embodiments of the present application, the material of at least a portion of the isolation structure 500 and at least a portion of the first shielding structure 600 may include a conductive material, such that the second electrodes 810 in adjacent isolation openings 500a are electrically connected by the isolation structure 500, and the shielding and shielding effect between the touch signals and the driving signals in the display panel 10 by the first shielding structure 600 can also be improved.

[0038] Optionally, the material of the first isolation portion 510 may include a conductive material, and the second electrodes 810 in adjacent isolation openings 500a are connected to each other by the first isolation portion 510 to form a surface electrode, facilitating control of the second electrodes 810 in the display panel 10.

[0039] In some alternative embodiments, the first shielding structure 600 includes a first shielding portion 610 and a second shielding portion 620 disposed on a side of the first shielding portion 610 away from the array substrate 100 .

[0040] Optionally, the material of the first shielding portion 610 includes a conductive material, and optionally, the first shielding portion 610 is provided in the same layer and made of the same material as the first isolation portion 510, and / or the second shielding portion 620 is provided in the same layer and made of the same material as the second isolation portion 520.

[0041] In these optional embodiments, by providing the first shielding structure 600, which includes a first shielding portion 610 and a second shielding portion 620 stacked on the array substrate 100, the first shielding portion 610 is provided in the same layer and made of the same material as the first isolation portion 510, and the second shielding portion 620 is provided in the same layer and made of the same material as the second isolation portion 520, the first shielding structure 600 is manufactured in the same process step as the isolation structure 500, and the first shielding structure 600 can limit mutual interference between touch signals and other signals in the display panel 10, and can simplify the manufacturing process of the display panel 10 and improve the manufacturing efficiency of the display panel 10.

[0042] Optionally, the first shielding structure 600 located in the non-display area NA may be connected to the isolation structure 500 located in the display area AA, so that the first shielding structure 600 and the isolation structure 500 can be more easily manufactured in the same process step, further improving the manufacturing efficiency of the display panel 10.

[0043] In some optional embodiments, the first shielding structure 600 is connected to a DC voltage signal terminal of the display panel 10, so that the first shielding structure 600 can provide a relatively stable voltage through the DC voltage signal terminal, thereby improving the shielding and shielding effect between the touch signal and the driving signal in the display panel 10 by the first shielding structure 600, and making it less likely that mutual interference will occur between the touch signal and the driving signal in the display panel 10.

[0044] Optionally, the signal lines of the DC voltage signal terminals may include at least one of a touch ground signal line, an initialization signal line, a negative power supply voltage signal line, and a positive power supply voltage signal line.

[0045] FIG. 5 is a schematic diagram of a partial structure of a first shielding structure 600 according to an embodiment of the present application.

[0046] 4 and 5, in some selectable embodiments, the first shielding structure 600 is provided with a plurality of first shielding openings 600a, which can release water vapor in the display panel 10, making the display panel 10 less likely to be destroyed by water vapor pressure. For example, the first shielding openings 600a may be used to release water vapor generated by a remanufacturing process (e.g., baking) of a part of the organic material layer structure of the display panel 10, and the first shielding openings 600a may be used for water vapor generated by a reliability test (simulating a user's usage scene) of the display panel 10.

[0047] Alternatively, the orthogonal projection of the first shielding portion 610 on the array substrate 100 can be located within the orthogonal projection of the second shielding portion 620 on the array substrate 100, so that the shape of the first shielding structure 600 can approximate the shape of the isolation structure 500, and the first shielding opening 600a provided by the first shielding structure 600 is manufactured by a similar or the same manufacturing process as the isolation opening 500a, and the first shielding opening 600a and the isolation opening 500a are manufactured in the same process step, thereby further simplifying the manufacturing process of the display panel 10 and improving the manufacturing efficiency of the display panel 10.

[0048] Optionally, there are multiple configuration ways of the first shielding opening 600a, where the shape of the first shielding opening 600a can be set according to the water vapor discharging needs of the display panel 10. For example, the shape of the first shielding opening 600a when orthogonally projected onto the array substrate 100 may be a polygon, a closed curve, an irregular shape, etc.

[0049] Optionally, the plurality of first shielding openings 600a are spaced apart in the first direction Y and / or the second direction Z to improve the ability of the first shielding openings 600a to release water vapor.

[0050] Optionally, the orthogonal projection of the touch assembly 900 located in the non-display area NA on the array substrate 100 is located within the orthogonal projection of the first shielding structure 600 on the array substrate 100.

[0052] As shown in FIG. 6, in some optional embodiments, the display panel 10 further includes a second shielding structure 200 located on the side of the first shielding structure 600 facing the array substrate 100, and a positive projection of at least a portion of the second shielding structure 200 in the thickness direction X of the display panel 10 covers the first shielding opening 600a.

[0053] Optionally, the orthogonal projection of the first shielding opening 600 a on the array substrate 100 is located within the orthogonal projection of the second shielding structure 200 on the array substrate 100 .

[0054] By providing the second shielding structure 200 located on the side of the first shielding structure 600 facing the array substrate 100, and the orthogonal projection of the first shielding opening 600a on the array substrate 100 being located within the orthogonal projection of at least a part of the second shielding structure 200 on the array substrate 100, the second shielding structure 200 can effectively shield the first shielding opening 600a in the thickness direction X of the display panel 10, and provide effective shielding and shielding effect between the touch signal and other signals on the display panel 10, and the touch signal and other signals on the display panel 10 are less likely to interfere with each other due to the first shielding opening 600a, thereby further improving the operational reliability of the display panel 10.

[0055] Optionally, the pixel limiting portion 410 may further include a plurality of third shielding openings located in the non-display area NA, and the third shielding openings may release water vapor in the display panel 10 to prevent the display panel 10 from being destroyed by water vapor pressure.

Optionally, an orthogonal projection of at least a portion of the second shielding structure 200 in the thickness direction X of the display panel 10 covers the third shielding opening.

[0057] Optionally, the material of the second shielding structure 200 may include a conductive material. Optionally, the second shielding structure 200 is connected to a DC voltage signal terminal of the display panel 10, so that the second shielding structure 200 can provide a relatively stable voltage through the DC voltage signal terminal, thereby improving the shielding and shielding effect between the touch signal and the driving signal in the display panel 10 by the second shielding structure 200, and making it difficult for mutual interference to occur between the touch signal and the driving signal in the display panel 10.

[0060] 7 and 8, in some selectable embodiments, the second shielding structure 200 includes a plurality of second shielding openings 200a. The second shielding openings 200a can release water vapor in the display panel 10 and prevent the display panel 10 from being pressure-destroyed by water vapor. For example, the second shielding openings 200a can be used to release water vapor generated by a remanufacturing process (e.g., baking) of a part of the organic material layer structure of the display panel 10, and the second shielding openings 200a can be used for water vapor generated by a reliability test (e.g., simulating a user's usage scene) of the display panel 10.

[0061] Optionally, there are multiple configuration ways of the shape of the second shielding opening 200a, where the shape of the second shielding opening 200a can be set according to the water vapor discharging needs of the display panel 10. For example, the shape of the second shielding opening 200a when orthogonally projected onto the array substrate 100 may be a polygon, a closed curve, an irregular shape, etc.

[0062] In some optional embodiments, the orthogonal projection of the first shielding structure 600 on the array substrate 100 is located within the orthogonal projection of the second shielding structure 200 on the array substrate 100, or the orthogonal projection of the first shielding structure 600 on the array substrate 100 overlaps with the orthogonal projection of the second shielding structure 200 on the array substrate 100.

[0063] By reasonably configuring the dimensions of the second shielding structure 200 and the second opening, the second shielding structure 200 can limit the mutual interference between signals and improve the operation reliability of the display panel 10 .

[0064] Optionally, the orthogonal projection of at least a portion of the first shielding structure 600 in the thickness direction X of the display panel 10 covers the second shielding opening 200a.

[0065] Optionally, the orthogonal projection of the second shielding opening 200a on the array substrate 100 is spaced apart from the orthogonal projection of the first shielding opening 600a on the array substrate 100. Optionally, the orthogonal projection of the second shielding opening 200a on the array substrate 100 is located within the orthogonal projection of the first shielding structure 600 on the array substrate 100.

[0066] In these optional embodiments, by rationally setting the relative positional relationship between the second shielding opening 200a and the first shielding opening 600a, the second shielding structure 200 can effectively shield the first shielding opening 600a in the thickness direction X of the display panel 10, and the first shielding structure 600 can effectively shield the second shielding opening 200a, so that the touch signal and other signals in the display panel 10 are less likely to interfere with each other through the first shielding opening 600a and the second shielding opening 200a, and the operational reliability of the display panel 10 is further improved.

[0067] In some alternative embodiments, the second shielding openings 200a are spaced apart in the first direction Y and / or the second direction Z to improve the ability of the second shielding openings 200a to release water vapor.

[0068] In some alternative embodiments, the orthogonal projection of the inner wall of the second shielding opening 200a on the array substrate 100 and the orthogonal projection of the inner wall of the first shielding opening 600a on the array substrate 100 have a predetermined distance, which is 20 μm or more.

[0069] Optionally, the predetermined spacing is greater than or equal to 25 μm and less than or equal to 35 μm. Optionally, the predetermined spacing may be 29 μm, 30 μm, or 31 μm.

[0070] Alternatively, a plurality of first shielding openings 600a may be provided around a portion of the second shielding openings 200a, and / or a plurality of second shielding openings 200a may be provided around a portion of the first shielding openings 600a.

[0071] In these alternative embodiments, if the predetermined distance between the first shielding opening 600a and the second shielding opening 200a is too small, for example, the predetermined distance is less than 20 μm, the touch signal and other signals in the display panel 10 are likely to interfere with each other due to the adjacent first shielding opening 600a and second shielding opening 200a, and the first shielding structure 600 and the second shielding structure 200 cannot effectively restrict the mutual interference between the touch signal and other signals in the display panel 10. In addition, if the predetermined distance between the first shielding opening 600a and the second shielding opening 200a is too large, for example, the predetermined distance is greater than 35 μm, water vapor is not easily released through the first shielding opening 600a and the second shielding opening 200a, and the display panel 10 is easily damaged. Therefore, by rationally setting the relative positional relationship between the first shielding opening 600a and the second shielding opening 200a, the touch signal of the display panel 10 and other signals in the display panel 10 are less likely to interfere with each other, and the display panel 10 is less susceptible to damage by water vapor generated during manufacture or use, thereby effectively improving the operational reliability of the display panel 10.

[0072] In some alternative embodiments, the position of the second shielding structure 200 can be set in various ways. Here, the second shielding structure 200 can be disposed between the first shielding structure 600 and the driving circuit 170 of the array substrate 100, and the orthogonal projection of at least a part of the driving circuit 170 on the array substrate 100 is located within the orthogonal projection of the second shielding structure 200 on the array substrate 100.

[0073] 7, in some alternative embodiments, at least a portion of the second shielding structures 200 may be provided in the array substrate 100. Optionally, at least a portion of the second shielding structures 200 are disposed in the same layer as at least a portion of the power supply signal lines of the display panel 10, and / or at least a portion of the second shielding structures 200 are disposed in the same layer as at least a portion of the data signal lines of the display panel 10, so that at least a portion of the second shielding structures 200 can be manufactured in the same process step as the power supply signal lines and / or the data signal lines, thereby improving the manufacturing efficiency of the display panel 10.

[0074] For example, the array substrate 100 may further include a fourth insulating layer 150 located on a side of the third insulating layer 140 away from the base 110, and at least a portion of the second shielding structure 200 may be provided in the fourth insulating layer 150, and / or the array substrate 100 may further include a fifth insulating layer 160 located on a side of the fourth insulating layer 150 away from the base 110, and at least a portion of the second shielding structure 200 may be provided in the fifth insulating layer 160.

[0075] FIG. 9 is a partial cross-sectional view of a display panel 10 according to yet another embodiment of the present invention.

Thus, by providing the second shielding structure 200, it is possible to limit mutual interference between the touch signal and other signals in the display panel 10, simplify the manufacturing process of the display panel 10, and improve the manufacturing efficiency of the display panel 10.

[0077] FIG. 10 is a partial cross-sectional view of a display panel according to still another embodiment of the present invention.

[0079] In this embodiment, the structures of the array substrate 100 and the light emitting layer 700 can be the same as or similar to the structures of the array substrate 100 and the light emitting layer 700 mentioned in any of the above embodiments. By providing the first shielding layer 11a and the second shielding layer 11b stacked in the non-display area AA of the display panel 10, the mutual interference between the signal in the array substrate 100 and the touch signal in the touch assembly 900 can be effectively reduced, and the operation reliability of the display panel 10 can be effectively improved.

[0082] Optionally, the display panel 10 further includes a second electrode layer 800 disposed on one side of the array substrate 100, the second electrode layer 800 including a plurality of second electrodes 810 disposed in the isolation openings 500a.

[0085] Optionally, the first shielding layer 11a may be provided between the light-emitting layer 700 and the fifth insulating layer 160 and / or in the fifth insulating layer 160 of the array substrate 100, and the second shielding layer 11b may be provided in any layer between the first shielding layer 11a and the third insulating layer 140.

[0086] For example, the first shielding layer 11a may be provided between the light emitting layer 700 and the fifth insulating layer 160, in the same layer as the first electrode 310, and the second shielding layer 11b may be provided in the fourth insulating layer 150.

[0087] In some alternative embodiments, the shielding layer 11 is provided with a vent hole 11c, which is used to release water vapor in the display panel 10, so that the display panel 10 is less susceptible to pressure destruction by water vapor.

[0088] Optionally, both the first shielding layer 11a and the second shielding layer 11b are provided with ventilation holes 11c, and in this case, the orthogonal projection of at least a portion of the first shielding layer 11a in the thickness direction X of the display panel 10 is provided to cover the ventilation holes 11c in the second shielding layer 11b, and / or the orthogonal projection of at least a portion of the second shielding layer 11b in the thickness direction X of the display panel 10 is provided to cover the ventilation holes 11c in the first shielding layer 11a.
