[0132] For example, at least one film layer in the light-emitting functional layer 21 is disconnected at the blocking structure 14C, so that the disconnected film layer in the light-emitting functional layer 21 is a discontinuous structure at the blocking structure 14C. Even if part of the light-emitting functional layer 21 is overlapped on the side wall of the isolation structure 15 on the side of the blocking structure 14C away from the center of the light-emitting device, the lateral flow (lateral leakage) of charges in the light-emitting device 20 can be avoided or improved. For example, the flow of charges between the light-emitting functional layer 21 and the isolation structure 15 can be avoided or improved, thereby avoiding the lateral flow or escape (lateral leakage) of charges in the light-emitting functional layer 21 through the isolation structure 15 on the side of the blocking structure 14C away from the center of the light-emitting device 20, thereby improving the luminous efficiency of the light-emitting device 20 and improving the display quality of the display panel.

[0133] In the embodiment of the present application, a blocking structure 14C is provided between the isolation structure 15 located on one side of the light-emitting device 20 and the center of the light-emitting device 20, and at least one film layer in the light-emitting functional layer 21 is disconnected at the blocking structure 14C. On the one hand, the film layer disconnected in the light-emitting functional layer 21 is made to be a discontinuous structure at the blocking structure 14C, and even if the light-emitting functional layer 21 is partially overlapped on the side wall of the isolation structure 15 on the side of the blocking structure 14C away from the center of the light-emitting device, the lateral flow of charges in the light-emitting device 20 can be avoided or improved, for example, the flow of charges between the light-emitting functional layer 21 and the isolation structure 15 can be avoided or improved, thereby avoiding the lateral flow or escape of charges in the light-emitting functional layer 21 through the isolation structure 15 on the side of the blocking structure 14C away from the center of the light-emitting device 20, thereby improving the luminous efficiency of the light-emitting device 20 and improving the display quality of the display panel. On the other hand, no blocking structure 14C is set between the isolation structure 15 located on one side of the light-emitting device 20 and the center of the light-emitting device 20. The second electrode 22 of the light-emitting device 20 can be overlapped on the isolation structure 15 on the side where the blocking structure 14C is not set. When the isolation structure 15 is a conductive structure, it is convenient to provide an electrical signal to the second electrode 22 through the isolation structure 15 on the side where the blocking structure 14C is not set.

[0134] In some embodiments, the two adjacent and oppositely arranged isolation structures 15 on both sides of the light-emitting device 20 respectively include a first isolation side wall 15a and a second isolation side wall 15b. On a plane parallel to the array substrate 10, the blocking structure 14C is located between the first isolation side wall 15a and the center of the light-emitting device 20; the second electrode 22 of the light-emitting device 20 is overlapped on the second isolation side wall 15b.

[0135] For example, Figure 3 , Figure 6 and Figure 8 As shown, two isolation structures 15 are arranged opposite to each other on both sides of the light emitting device 20, and the two side walls of the two isolation structures 15 facing the light emitting device 20 are respectively a first isolation side wall 15a and a second isolation side wall 15b, that is, Figure 1 As shown in the figure, a blocking structure 14C is arranged between one of the first isolation side wall 15a and the second isolation side wall 15b and the center (or central area, or light-emitting area) of the light-emitting device 20, and no blocking structure 14C is arranged between the other of the first isolation side wall 15a and the second isolation side wall 15b and the center (or central area, or light-emitting area) of the light-emitting device 20. Figures 1 to 9 In the example, a blocking structure 14C is provided between the first isolation sidewall 15 a and the center (or the center area, or the light emitting area) of the light emitting device 20 .

[0136] For example, Figure 3 , Figure 6 and Figure 8 As shown, the first isolation structure 15K1 includes a first isolation sidewall 15 a facing the light emitting device 20 , and the second isolation structure 15K2 includes a second isolation sidewall 15 b facing the light emitting device 20 .

[0137] For example, Figure 3 , Figure 6 and Figure 8 As shown by the middle elliptical dotted line 101 , the second electrode 22 of the light emitting device 20 is overlapped on the second isolation sidewall 15 b . When the second isolation structure 15K2 is a conductive structure, it is convenient to provide an electrical signal to the second electrode 22 through the second isolation structure 15K2 .

[0138] Optionally, in some embodiments, all film layers in the light-emitting functional layer 21 are disconnected at the blocking structure 14C.

[0139] For example, all the film layers in the light-emitting functional layer 21 are disconnected at the blocking structure 14C, which can better avoid or improve the lateral flow of charges in the light-emitting device 20. For example, it can better avoid or improve the flow of electrical signals between the light-emitting functional layer 21 and the isolation structure 15, thereby avoiding the lateral flow or escape (lateral leakage) of charges in the light-emitting functional layer 21 through the first isolation side wall 15a, thereby improving the luminous efficiency of the light-emitting device 20 and improving the display quality of the display panel.

[0140] Optionally, in some embodiments, all film layers in the light-emitting functional layer 21 and the second electrode 22 are disconnected at the blocking structure 14C.

[0141] For example, all the film layers in the light-emitting functional layer 21 and the second electrode 22 are disconnected at the blocking structure 14C. On the one hand, the lateral flow of charges in the light-emitting device 20 can be further avoided or improved, for example, the lateral flow or escape of charges through the first isolation sidewall 15a in the light-emitting functional layer 21 can be better avoided or improved, thereby improving the luminous efficiency of the light-emitting device 20 and improving the display quality of the display panel. On the other hand, other forms of lateral flow of charges can also be prevented or improved. For example, the second isolation structure 15K2 provides an electrical signal to the second electrode 22, and can also prevent the electrical signal from being transmitted from the first electrode portion 221 (the portion of the second electrode 22 located on the side of the blocking structure 14C away from the first isolation sidewall 15a) to the second electrode portion 222 (the portion of the second electrode 22 located on the side of the blocking structure 14C away from the second isolation sidewall 15b) and then flowing out through the first isolation structure 15K1 (without reaching the light-emitting layer), thereby improving the luminous efficiency of the light-emitting device 20 and improving the display quality of the display panel.

[0142] In some embodiments, the light-emitting functional layer 21 includes a first light-emitting functional portion 211 and a second light-emitting functional portion 212, the first light-emitting functional portion 211 is located on a side of the blocking structure 14C away from the first isolation sidewall 15a, and the second light-emitting functional portion 212 is located on a side of the isolation structure 15 away from the second isolation sidewall 15b; the first light-emitting functional portion 211 in at least part of the light-emitting device 20 is spaced apart from the second isolation sidewall 15b, and the second electrode 22 covers the edge of the first light-emitting functional portion 211 away from the first isolation sidewall 15a.

[0143] For example, in the direction from the first isolation sidewall 15 a toward the light emitting device 20 , the first light emitting function part 211 and the second light emitting function part 212 are respectively located on both sides of the blocking structure 14C, and the first light emitting function part 211 covers the center of the light emitting device.

[0144] For example, Figure 3 , Figure 6 and Figure 8 As shown by the middle elliptical dotted line 101, the first light-emitting functional portion 211 in at least part of the light-emitting device 20 is spaced apart from the second isolation sidewall 15b, and the second electrode 22 covers the edge of the first light-emitting functional portion 211 away from the first isolation sidewall 15a, which can facilitate the second electrode 22 to overlap on the second isolation sidewall 15b, prevent the first light-emitting functional portion 211 from spacing the second electrode 22 from the second isolation sidewall 15b, increase the area of ​​the second electrode 22 overlapping on the second isolation sidewall 15b, reduce the contact resistance between the second electrode 22 and the second isolation sidewall 15b, and prevent uneven display.

[0145] In some embodiments, at least a portion of the second light emitting function portion 212 in the light emitting device 20 overlaps the first isolation side wall 15 a .

[0146] For example, in some embodiments, during the manufacturing process of the display panel 100, during the formation process of the light-emitting functional layer 21, in order to make the first light-emitting functional part 211 in the light-emitting device 20 spaced from the second isolation sidewall 15b, or in order to make the second electrode 22 directly overlap the second isolation sidewall 15b, it is necessary to control the evaporation angle formed by the light-emitting functional layer 21, for example, the evaporation angle is toward the first isolation sidewall 15a, so that at least part of the second light-emitting functional part 212 in the light-emitting device 20 overlaps the first isolation sidewall 15a. However, the second light-emitting functional part 212 overlaps the first isolation sidewall 15a, which will cause part of the charge to flow laterally in the light-emitting functional layer 21 and be lost. For example, the charge provided by the second isolation structure 15K2 to the second electrode 22 does not reach the light-emitting functional layer and directly flows to the first isolation structure 15K1, resulting in charge loss, reducing the light-emitting efficiency of the light-emitting device 20, and thus causing the image quality of the display panel to deteriorate. The blocking structure 14C of the present application can avoid or improve the lateral flow of charges in the light-emitting functional layer 21, thereby improving the light-emitting efficiency of the light-emitting device 20 and enhancing the display quality of the display panel.

[0147] Optionally, in some embodiments, the orthographic projection of the second light-emitting functional portion 212 on the array substrate 10 covers the orthographic projection of the edge of the second electrode 22 close to the first isolation sidewall 15 a on the array substrate 10 .

[0148] For example, Figure 3 , Figure 6 and Figure 8 As shown by the dotted line 102 in the middle rectangle, during the manufacturing process of the display panel 100, during the formation process of the second electrode 22, in order to make the second electrode 22 directly overlap the second isolation side wall 15b, it is necessary to control the formation angle of the second electrode 22. For example, when the second electrode 22 is formed by the evaporation process, the evaporation angle is controlled to be toward the second isolation side wall 15b, resulting in the second electrode 22 not directly overlapping the first isolation side wall 15a, so that at the first isolation side wall 15a, at least part of the second light-emitting functional part 212 of the light-emitting device 20 overlaps the first isolation side wall 15a, while the second electrode 22 is not overlapped on the first isolation side wall 15a, which easily causes the charge to flow horizontally in the light-emitting functional layer 21, resulting in charge loss, reducing the light-emitting efficiency of the light-emitting device 20, and thus causing the display panel image quality to decline. The blocking structure 14C of the present application can avoid or improve the lateral flow of charges in the light-emitting functional layer 21, thereby improving the light-emitting efficiency of the light-emitting device 20 and improving the display image quality of the display panel.

[0149] In some embodiments, the isolation structure 15 includes a support portion 152 and a crown portion 153 stacked in sequence on the array substrate 10, and the orthographic projection of the support portion 152 on the array substrate 10 is located within the orthographic projection of the crown portion 153 on the array substrate 10; the first isolation side wall 15a and the second isolation side wall 15b are both side walls of the support portion 152 of the corresponding isolation structure 15.

[0150] Optionally, the support portion 152 and the crown portion 153 are integrally formed.

[0151] Optionally, the materials of the support portion 152 and the crown portion 153 are different.

[0152] Optionally, the support portion 152 includes a conductive material.

[0153] For example, the isolation structure 15 includes a support portion 152 and a crown portion 153 which are sequentially stacked on the array substrate 10, and the orthographic projection of the support portion 152 on the array substrate 10 is located within the orthographic projection of the crown portion 153 on the array substrate 10. In this way, at least the portion of the isolation structure 15 away from the substrate 11 is set to a shape that is wide at the top and narrow at the bottom, so that the isolation structure 15 can block other film layers such as the light-emitting functional layer 21 or the hole transport layer HTL of the adjacent light-emitting device 20, which can save expensive fine metal mask plates (FMM), thereby reducing the manufacturing cost of the display panel. At the same time, after not using the fine metal mask plate (FMM), the light-emitting area of ​​the sub-pixel is not limited by the opening of the fine metal mask plate, the light-emitting area of ​​the sub-pixel can be made smaller, and a larger number of sub-pixels can be formed in the display panel, thereby improving the resolution of the display panel.

[0154] For example, the support portion 152 and the crown portion 153 may be a multi-layered structure, which is convenient for being formed of different materials. For example, the support portion 152 is designed to be a conductive material, and the crown portion 153 is set to be an insulating material. For example, the support portion 152 is designed to be a conductive material, and the crown portion 153 is set to be a conductive material, but the etching rate of the support portion 152 is greater than the etching rate of the crown portion 153. For example, the support portion 152 and the crown portion 153 can be set as an integrated structure to increase the firmness of the isolation structure 15.

[0155] For example, the support portion 152 includes at least one metal layer. In one example, the support portion 152 includes a metal layer. Further, the material of the support portion 152 includes at least one of a metal and a metal oxide. For example, the metal may be silver, copper, titanium, aluminum, etc. The metal oxide may be tin oxide, zinc oxide, cadmium oxide, indium oxide, indium tin oxide, zinc indium oxide, zinc gallium oxide, zinc aluminum oxide, titanium tantalum oxide, etc.

[0156] For example, the material of the crown 153 includes titanium or molybdenum.

[0157] For example, Figure 1 The isolation structure 15 is schematically shown to include a pad 151, a support portion 152 and a crown portion 153. The pad 151, the support portion 152 and the crown portion 153 can form an "I" shape or a "T" shape. The material of the pad 151 includes titanium or molybdenum, but is not limited thereto.

[0158] For example, Figure 1 , the isolation structure 15 is shown as a laminated structure of a pad portion 151, a support portion 152, and a crown portion 153. For example, the laminated structure of the isolation structure 15 may be titanium / aluminum / titanium or molybdenum / aluminum / molybdenum, the pad portion 151 is made of titanium or molybdenum, the support portion 152 is made of aluminum, and the crown portion 153 is made of titanium or molybdenum. By providing three stacked metal layers, the resistance of the isolation structure 15 can be reduced, thereby reducing the power consumption of the display panel 100.

[0159] For example, Figures 1 to 8 As shown, the first isolation sidewall 15a and the second isolation sidewall 15b are both sidewalls of the support portion 152 of the corresponding isolation structure 15, that is, the first isolation sidewall 15a is the sidewall of the support portion 152 of the first isolation structure 15K1 (as shown in FIG. Figure 1 The second isolation sidewall 15b is the sidewall of the support portion 152 of the second isolation structure 15K2 (as shown in FIG. Figure 1 When the support portion 152 is made of a conductive material, the second electrode 22 is overlapped on the side wall (second support portion side wall 152 b ) of the support portion 152 of the second isolation structure 15K2, and the second isolation structure 15K2 can provide an electrical signal for the second electrode 22.

[0160] See also Figures 1 to 3 .

[0161] In some embodiments, Figures 1 to 3 As shown, the display panel 100 further includes a first insulating layer 14J disposed between the array substrate 10 and the isolation structure 15 ; the blocking structure 14C includes at least one groove 14C1 located in the first insulating layer 14J.

[0162] For example, at least one groove 14C1 in the first insulating layer 14J can be set as a blocking structure 14C, so that at least one film layer in the light-emitting functional layer 21 is disconnected at the groove 14C1, which can avoid or improve the lateral flow of charges in the light-emitting functional layer 21, thereby improving the light-emitting efficiency of the light-emitting device 20 and improving the display quality of the display panel.

[0163] Optionally, in some embodiments, Figures 1 to 3As shown, along the direction of the first isolation sidewall 15 a toward the corresponding light emitting device 20 , the cross section of the groove 14C1 is at least one of a rectangular shape and a trapezoidal shape.

[0164] For example, in the direction in which the first isolation sidewall 15a and the second isolation sidewall 15b are opposite, the cross section of the groove 14C1 is at least one of a rectangle and a trapezoid, so that the light-emitting functional layer 21 can be better disconnected at the groove 14C1.

[0165] For example, Figure 1 , it is illustrated that in the direction along the first isolation side wall 15a toward the corresponding light emitting device 20, the cross section of the groove 14C1 is rectangular; Figure 2 FIG. 4 illustrates that in the direction along the first isolation sidewall 15 a toward the corresponding light emitting device 20 , the cross section of the groove 14C1 is trapezoidal.

[0166] Optionally, in some embodiments, Figures 1 to 3 As shown, the sidewall of the groove 14C1 includes a first groove sidewall 14C11 facing an adjacent light emitting device 20 and a second groove sidewall 14C12 away from the adjacent light emitting device 20 .

[0167] Optionally, in some embodiments, Figures 1 to 3 As shown, the angle between at least one of the first groove sidewall 14C11 and the second groove sidewall 14C12 and the bottom surface of the groove 14C1 is less than or equal to 90 degrees.

[0168] For example, Figure 1 It is shown that the angle between the first groove side wall 14C11 and the bottom surface of the groove 14C1 is the first groove angle α1, and the first groove angle α1 is less than or equal to 90 degrees. For example, the first groove angle α1 is any value of 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0169] For example, Figure 1 It shows that the angle between the second groove side wall 14C12 and the bottom surface of the groove 14C1 is the second groove angle α2, and the second groove angle α2 is less than or equal to 90 degrees. For example, the first groove angle α1 is any value of 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0170] For example, the angle between at least one of the first groove sidewall 14C11 and the second groove sidewall 14C12 and the bottom surface of the groove 14C1 is less than or equal to 90 degrees, so that the light-emitting functional layer 21 can be better disconnected in the groove 14C1.

[0171] In some embodiments, Figures 1 to 3 As shown, in a direction along the first isolation sidewall 15 a toward the corresponding light emitting device 20 , the size of the groove 14C1 is smaller than the size of the isolation structure 15 .

[0172] For example, Figure 1 As shown, in the direction along the first isolation side wall 15a toward the corresponding light-emitting device 20, the size of the groove 14C1 (the width of the groove 14C1 at one end close to the substrate 11) is the groove width d2, and the size (width) of the isolation structure 15 is the first width d1. The groove width d2 is smaller than the first width d1, which can avoid the blocking structure 14C occupying too large a layout area, which is beneficial to increasing the area of ​​the light-emitting region of the light-emitting device 20, or to improving the resolution of the display panel.

[0173] Optionally, in some embodiments, Figures 1 to 3 As shown, in a direction perpendicular to the plane where the array substrate 10 is located, the size of the groove 14C1 is smaller than the size of the isolation structure 15 .

[0174] For example, Figure 1 As shown, in the direction perpendicular to the plane where the array substrate 10 is located, the size of the groove 14C1 is the groove height h2, the size (height) of the isolation structure 15 is the first height h1, and the groove height h2 is smaller than the first height h1. The smaller the groove height h2, the easier it is to manufacture the groove 14C1 with a groove width d2 smaller than the first width d1, which can avoid the blocking structure 14C occupying too large a layout area, which is beneficial to increasing the area of ​​the light-emitting region of the light-emitting device 20, or to improving the resolution of the display panel.

[0175] Optionally, in a direction perpendicular to the plane where the array substrate 10 is located, the groove 14C1 does not penetrate the first insulating layer 14J.

[0176] For example, Figure 1 As shown, in the direction perpendicular to the plane where the array substrate 10 is located, the groove 14C1 does not penetrate the first insulating layer 14J. In the display panel 100, in the direction perpendicular to the plane where the array substrate 10 is located, the first insulating layer 14J also plays the role of insulating and isolating the film layers on both sides. The groove 14C1 does not penetrate the first insulating layer 14J, which can completely prevent the light-emitting functional layer 21 and / or the second electrode 22 from contacting the film layer on the side of the first insulating layer 14J close to the underlying substrate 11.

[0177] See also Figures 4 to 6 .

[0178] In some embodiments, Figures 4 to 6As shown, the display panel 100 further includes a first insulating layer 14J disposed between the array substrate 10 and the isolation structure 15 ; the blocking structure 14C includes at least one protruding structure 14D1 located on a side of the first insulating layer 14J away from the array substrate 10 .

[0179] For example, at least one protrusion structure 14D1 located on the side of the first insulating layer 14J away from the array substrate 10 can be set as a blocking structure 14C, so that at least one film layer in the light-emitting functional layer 21 is disconnected at the groove 14C1, which can avoid or improve the lateral flow of charges in the light-emitting functional layer 21, thereby improving the light-emitting efficiency of the light-emitting device 20 and improving the display quality of the display panel.

[0180] Optionally, in some embodiments, Figures 4 to 6 As shown, along the direction from the first isolation sidewall 15 a toward the light emitting device 20 , the cross section of the protrusion structure 14D1 is rectangular or inverted trapezoidal.

[0181] For example, along the direction from the first isolation sidewall 15 a toward the light emitting device 20 , the cross section of the protrusion structure 14D1 is rectangular or inverted trapezoidal, so that the light emitting function layer 21 can be better disconnected at the protrusion structure 14D1 .

[0182] For example, Figure 4 , it is illustrated that in the direction from the first isolation sidewall 15a toward the light emitting device 20, the cross section of the protrusion structure 14D1 is rectangular; Figure 5 FIG. 4 illustrates that in the direction along the first isolation sidewall 15 a toward the light emitting device 20 , the cross section of the protrusion structure 14D1 is in an inverted trapezoidal shape.

[0183] Optionally, in some embodiments, Figures 4 to 6 As shown, the sidewall of the protrusion structure 14D1 includes a first protrusion sidewall 14D11 facing an adjacent light emitting device 20 and a second protrusion sidewall 14D12 away from the adjacent light emitting device 20 .

[0184] Optionally, in some embodiments, Figures 4 to 6 As shown, the angle between at least one of the first protrusion side wall 14D11 and the second protrusion side wall 14D12 and the surface of the first insulating layer 14J away from the array substrate 10 is less than or equal to 90 degrees.

[0185] For example, Figure 4It is shown that the angle between the first protrusion side wall 14D11 and the surface of the first insulating layer 14J away from the array substrate 10 is the first protrusion angle β1, and the first protrusion angle β1 is less than or equal to 90 degrees. For example, the first protrusion angle β1 is any value of 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0186] For example, Figure 5 It is shown that the angle between the second protrusion side wall 14D12 and the surface of the first insulating layer 14J away from the array substrate 10 is the second protrusion angle β2, and the second protrusion angle β2 is less than or equal to 90 degrees. For example, the second protrusion angle β2 is any value of 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0187] For example, the angle between at least one of the first protrusion sidewall 14D11 and the second protrusion sidewall 14D12 and the surface of the first insulating layer 14J away from the array substrate 10 is less than or equal to 90 degrees, so that the light-emitting functional layer 21 can be better disconnected at the protrusion structure 14D1.

[0188] In some embodiments, Figures 4 to 6 As shown, in a direction parallel to the plane where the array substrate 10 is located, the size of the protrusion structure 14D1 is smaller than the size of the isolation structure 15 .

[0189] For example, Figure 4 As shown, in a direction parallel to the plane where the array substrate 10 is located, and in a direction along the first isolation side wall 15a toward the corresponding light-emitting device 20, the size of the protrusion structure 14D1 (the width of the end of the protrusion structure 14D1 away from the substrate 11) is the protrusion width d3, and the size (width) of the isolation structure 15 is the first width d1. The protrusion width d3 is smaller than the first width d1, which can avoid the blocking structure 14C occupying too large a layout area, which is beneficial to increasing the area of ​​the light-emitting region of the light-emitting device 20, or to improving the resolution of the display panel.

[0190] Optionally, in some embodiments, Figures 4 to 6 As shown, in a direction perpendicular to the plane where the array substrate 10 is located, the size of the protrusion structure 14D1 is smaller than the size of the isolation structure 15 .

[0191] For example, Figure 4As shown, in the direction perpendicular to the plane where the array substrate 10 is located, the size of the protrusion structure 14D1 is the protrusion height h3, the size (height) of the isolation structure 15 is the first height h1, and the protrusion height h3 is smaller than the first height h1. The smaller the protrusion height h3 is, the easier it is to manufacture the protrusion structure 14D1 whose protrusion width d3 is smaller than the first width d1, which can avoid the blocking structure 14C occupying too large a layout area, which is beneficial to increasing the area of ​​the light-emitting region of the light-emitting device 20, or to improving the resolution of the display panel.

[0192] Optionally, in some embodiments, Figures 4 to 6 As shown, the protrusion structure 14D1 and the first insulating layer 14J are an integral structure and can be formed in the same process, thereby simplifying the manufacturing process.

[0194] In some embodiments, Figure 7 and Figure 8 As shown, the display panel 100 also includes a first insulating layer 14J arranged between the array substrate 10 and the isolation structure 15, the first insulating layer 14J includes a first insulating structure 14J1, and a plurality of first openings 14J2 surrounded by the first insulating structure 14J1, the light-emitting device 20 is at least partially accommodated in the corresponding first opening 14J2, the side wall of the first insulating structure 14J1 includes a first opening side wall 14J11 close to the first isolation side wall 15a and facing the light-emitting device 20, the blocking structure 14C is the first opening side wall 14J11, and the angle between the first opening side wall 14J11 and the bottom surface of the first opening 14J2 is less than or equal to 90 degrees.

[0195] For example, Figure 7 As shown, the side wall of the first insulating structure 14J1 includes a first opening side wall 14J11 close to the first isolation side wall 15a and facing the light-emitting device 20. The angle between the first opening side wall 14J11 and the bottom surface of the first opening 14J2 is a first opening angle θ1. The first opening angle θ1 is less than or equal to 90 degrees, which can better disconnect the light-emitting functional layer 21 at the first opening side wall 14J11.

[0196] For example, Figure 7 As shown, the first opening angle θ1 is less than or equal to 90 degrees. For example, the first opening angle θ1 is any value of 90 degrees, 88 degrees, 86 degrees, 85 degrees, 83 degrees, 80 degrees, 78 degrees, 75 degrees, 70 degrees, 60 degrees, 55 degrees, 50 degrees, 45 degrees, 40 degrees, and 30 degrees.

[0199] For example, Figure 7 As shown, the second opening angle θ2 is greater than 90 degrees. For example, the second opening angle θ2 is any value of 100 degrees, 110 degrees, 120 degrees, 125 degrees, 130 degrees, 135 degrees, 140 degrees, 145 degrees, 150 degrees, and 160 degrees.

[0200] Optionally, an angle between the second opening sidewall 14J12 and the bottom surface of the first opening 14J2 is greater than or equal to 130 degrees.

[0201] For example, the second opening angle θ2 is greater than or equal to 130 degrees, so that the light-emitting functional layer 21 can be well and continuously extended at the second opening sidewall 14J12, thereby better avoiding the second electrode 22 from being broken at the second opening sidewall 14J12.

The isolation structure 15 is arranged on the side of the corresponding pixel definition structure 141 away from the array substrate 10.

[0204] For example, in some other embodiments, the pixel definition structure 141 does not cover the edge of the corresponding first electrode 131 .

Figure 7 The first pixel definition side wall 1411 in the middle), the second opening side wall 14112 is a side wall of the pixel definition structure 141 close to the second isolation side wall 15b and facing the center of the light emitting device 20 (such as Figure 7 The second pixel defines sidewall 1412).

The blocking structure 14C has the structure and function described above, which will not be described in detail.

[0225] Second, see Figures 1 to 3 , Figures 4 to 6 ,or Figure 7 and Figure 8The present application provides a display panel 100, which includes an array substrate 10, and a plurality of light-emitting devices 20, a plurality of isolation structures 15 and a plurality of blocking structures 14C arranged on the same side of the array substrate 10; the light-emitting device 20 includes a first electrode 131, a light-emitting functional layer 21 and a second electrode 22 stacked in sequence on one side of the array substrate 10, and the light-emitting functional layer 21 includes at least one film layer; at least part of the isolation structure 15 encloses an isolation opening 15K, and at least part of the light-emitting device 20 is arranged in the corresponding isolation opening 15K; on a plane parallel to the array substrate 10, a blocking structure 14C is arranged between the isolation structure 15 on at least one side of the light-emitting device 20 and the center of the light-emitting device 20, the blocking structure 14C is partially arranged around the center of the light-emitting device 20, and at least one film layer in the light-emitting functional layer 21 is disconnected at the blocking structure 14C.
