Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of display panels, and particularly relates to a display panel and a display device. BACKGROUND

[0002] Organic light emitting diode (OLED) display panels and display panels using light emitting diode (LED) devices and other flat display panels have been widely applied to mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, desktop computers and other consumer electronic products due to their high image quality, power saving, thin body and wide application range, and have become the mainstream of display devices. However, the yield of the edge area in the current display panel is poor. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least solve the problem of poor yield of the edge area in the display panel. The purpose is achieved by the following technical solutions:

[0004] The first aspect of the present application provides a display panel, the display panel comprising a display area and a frame area located outside the display area, and the display panel comprising:

[0005] An array substrate, the array substrate comprising a metal structure located in the frame area;

[0006] A light emitting layer located on one side of the array substrate;

[0007] A filter layer, the filter layer located on a side of the light emitting layer away from the array substrate, the filter layer partially located in the frame area, and a projection of the filter layer on the array substrate at least partially overlapping with a projection of the metal structure on the array substrate;

[0008] An encapsulation glue located on a side of the filter layer away from the array substrate and in the frame area;

[0009] An optical shielding layer located on a side of the encapsulation glue away from the array substrate and in the frame area, the optical shielding layer comprising an optical shielding area and a plurality of light transmission areas, a projection of the light transmission area on the array substrate located within a projection of the encapsulation glue on the array substrate, and a projection of the light transmission area on the array substrate located within a projection of the filter layer on the array substrate.

[0010] The display panel provided herein comprises an array substrate having a metal structure formed therein, which is used to control light emission from a light-emitting layer. The light-emitting layer is disposed on one side of the array substrate and is used to emit light for display. The light-emitting layer is at least partially located in the display area, and may also be partially located in the frame area. A filter layer is located on the side of the light-emitting layer facing away from the array substrate, with a portion of the filter layer located in the frame area, and the portion of the filter layer located in the frame area is located between the light-emitting layer and the encapsulant. The filter layer is used to filter light emitted by the light-emitting layer to improve the purity of the light emitted by the display panel. The filter layer also filters light entering the display panel, reducing the transmittance, thereby reducing the amount of light entering the display panel and thereby reducing the reflectivity of light reflected by the film layer within the display panel. The orthographic projection of the filter layer on the array substrate at least partially overlaps with the orthographic projection of the metal structure on the array substrate. By shielding the metal structure from the filter layer, the probability of external light striking the metal structure and being reflected and emitted from the light-emitting surface of the display panel is reduced. The encapsulant is located on the side of the filter layer facing away from the array substrate and in the border area, and is used to encapsulate the border area. The light-shielding layer is located on the side of the encapsulant facing away from the array substrate and is located in the border area. It is used to shield the border area, preventing light reflected from the metal structure in the border area from being emitted from the light-emitting surface of the display panel. It also shields the encapsulant, thereby preventing the internal structure of the border area (including the encapsulant frame) from being visible from the light-emitting side of the display panel, which would affect the visual effect.

[0011] In the display panel provided by the present application, the light-shielding layer includes a light-shielding area and multiple light-transmitting areas. By forming the light-transmitting area in the light-shielding layer, the transmittance of light can be improved. By setting the orthographic projection of the light-transmitting area on the array substrate to be located within the orthographic projection of the encapsulating glue on the array substrate, the transmittance of light (such as ultraviolet light) for curing the encapsulating glue can be increased, which facilitates the curing of the formed encapsulating glue, so that the curing effect of the encapsulating glue is better, and the problem of late warping and falling off caused by poor curing of the encapsulating glue is improved, that is, the curing effect of the encapsulating glue is improved, the preparation yield of the encapsulating glue is improved, and the yield of the display panel frame area is improved. The orthographic projection of the light-transmitting area on the array substrate is set within the orthographic projection of the filter layer on the array substrate, and the filter layer can reduce the transmittance to achieve supplementary light shielding of the light-transmitting area, improve the reflectivity of the metal structure to light, and further improve the problem of light leakage in the edge area.

[0012] In some embodiments of the present application, the ratio of the total area of ​​the light-transmitting region to the total area of ​​the light-shielding layer is in a range of 20%-30%.

[0013] In some embodiments of the present application, the light-transmitting area includes a plurality of light-transmitting holes penetrating the light-shielding layer along a thickness direction of the light-shielding layer, and the plurality of light-transmitting holes are dispersedly arranged.

[0014] In some embodiments of the present application, the light-transmitting area further includes a light-transmitting material filled in the light-transmitting hole.

[0015] In some embodiments of the present application, the light-transmitting material is made of the same material as the packaging adhesive.

[0016] In some embodiments of the present application, the outer diameter of the light-transmitting hole is in the range of 9 μm-11 μm.

[0017] In some embodiments of the present application, the portion of the filter layer located in the border area includes an opening, and the orthographic projection of the opening on the array substrate does not overlap with the orthographic projection of the light-transmitting area on the array substrate.

[0018] In some embodiments of the present application, the filter layer includes a filter function portion, and the plurality of filter function portions include a red filter portion, a green filter portion, and a blue filter portion, wherein:

[0019] The portion of the filter layer located in the frame area includes a layer of the red filter portion or a layer of the blue filter portion.

[0020] In some embodiments of the present application, the filter layer includes a filter function portion, and the plurality of filter function portions include a red filter portion, a green filter portion, and a blue filter portion, wherein:

[0021] The portion of the filter layer located in the frame area includes multiple layers of filter portions arranged in a direction away from the array substrate, and the multiple layers of filter portions have different colors.

[0022] In some embodiments of the present application, the opening portion penetrates multiple layers of the filter portions arranged in a direction away from the array substrate.

[0023] In some embodiments of the present application, the metal structure includes part or all of a metal trace, a cathode ring, and a metal sealing ring.

[0024] In some embodiments of the present application, the display panel further includes a cutting street area, the cutting street area is located outside the frame area, and the array substrate further includes a test pattern located in the cutting street area;

[0047] like Figure 1 and Figure 2 As shown, according to an embodiment of the present application, a display panel 1 is proposed, which includes a display area A1 and a frame area B1 located outside the display area A1. The display panel 1 includes an array substrate 11, a light-emitting layer 12, a filter layer 17, a packaging glue 13 and a light-shielding layer 14. The array substrate 11 includes a metal structure located in the frame area B1. The light-emitting layer 12 is located on one side of the array substrate 11. The filter layer 17 is located on the side of the light-emitting layer 12 away from the array substrate 11, and the filter layer 17 is partially located in the frame area B1. The orthographic projection of the filter layer 17 on the array substrate 11 at least partially overlaps with the orthographic projection of the metal structure on the array substrate 11. The packaging glue 13 is located on the side of the filter layer 17 away from the array substrate 11 and is located in the frame area B1. The light-shielding layer 14 is located on the side of the packaging glue 13 facing away from the array substrate 11, and is located in the border area B1. The light-shielding layer 14 includes a light-shielding area 141 and multiple light-transmitting areas 142. The orthographic projection of the light-transmitting area 142 on the array substrate 11 is located within the orthographic projection of the packaging glue 13 on the array substrate 11, and the orthographic projection of the light-transmitting area 142 on the array substrate 11 is located within the orthographic projection of the filter layer 17 on the array substrate 11.

[0048] In the display panel 1 provided in the present application, a metal structure is formed in the array substrate 11, and the array substrate 11 is used to control the light emission of the light-emitting layer 12. The light-emitting layer 12 is provided on one side of the array substrate 11 and is used to emit light for display. The light-emitting layer 12 is at least partially located in the display area A1, and part of the light-emitting layer 12 may also be located in the border area B1. The filter layer 17 is located on the side of the light-emitting layer 12 away from the array substrate 11, and part of the filter layer 17 is located in the border area B1. The part of the filter layer 17 located in the border area B1 is located between the light-emitting layer 12 and the packaging glue 13. The filter layer 17 is used to filter the light emitted by the light-emitting layer 12 to improve the light purity of the display panel 1. The filter layer 17 can also filter the light from the outside that enters the interior of the display panel 1, thereby reducing the transmittance, thereby reducing the amount of light from the outside that enters the display panel 1, and thereby reducing the reflectivity of the film layer inside the display panel 1 to reflect the light. The orthographic projection of the filter layer 17 on the array substrate 11 at least partially overlaps with the orthographic projection of the metal structure on the array substrate 11. By shielding the metal structure with the filter layer 17, the probability of external light irradiating the metal structure and being reflected and emitted from the light-emitting surface of the display panel 1 can be reduced. The encapsulation glue 13 is located on the side of the filter layer 17 facing away from the array substrate 11 and is located in the border area B1. The encapsulation glue 13 is used to achieve encapsulation of the border area B1. The light-shielding layer 14 is located on the side of the encapsulation glue 13 facing away from the array substrate 11. The light-shielding layer 14 is located in the border area B1 and is used to shield the border area B1, preventing light reflected from the metal structure in the border area B1 from emitting from the light-emitting surface of the display panel 1. The light-shielding layer 14 can also shield the encapsulation glue 13, thereby preventing the internal structure in the border area B1 (including the border of the encapsulation glue 13) from being seen from the light-emitting side of the display panel 1, thereby affecting the visual effect.

[0049] In the display panel 1 provided in the present application, the light-shielding layer 14 includes a light-shielding area 141 and a plurality of light-transmitting areas 142. By forming the light-transmitting area 142 in the light-shielding layer 14, the transmittance of light can be improved. By setting the orthographic projection of the light-transmitting area 142 on the array substrate 11 to be located within the orthographic projection of the encapsulation glue 13 on the array substrate 11, the transmittance of light (such as ultraviolet light) for curing the encapsulation glue 13 can be increased, which facilitates the curing of the formed encapsulation glue 13, so that the curing effect of the encapsulation glue 13 is better, and the problem of later warping and falling off caused by poor curing of the encapsulation glue 13 is improved, that is, the curing effect of the encapsulation glue 13 is improved, the preparation yield of the encapsulation glue 13 is improved, and the yield of the border area B1 of the display panel 1 is improved. The orthographic projection of the light-transmitting area 142 on the array substrate 11 is set within the orthographic projection of the filter layer 17 on the array substrate 11. The filter layer 17 can reduce the transmittance to achieve supplementary shading of the light-transmitting area 142, improve the reflectivity of the metal structure to light, and further improve the problem of light leakage in the edge area.

[0050] Specifically, the display panel 1 also includes a glass cover plate 15, which is located on the side of the light shielding layer 14 facing away from the array substrate 11. If the encapsulant 13 is poorly cured, the display panel 1 may warp or fall off after the glass cover plate 15 is attached to the display panel 1. This may cause bubbles to form within the display panel 1 and affect the yield of the display panel 1. In the present application, by improving the curing yield of the encapsulant 13, defects such as bubbles in the display panel 1 can be improved, thereby improving the manufacturing yield of the display panel 1.

[0051] Specifically, the light shielding layer 14 can be directly formed on the edge region of the glass cover 15 .

[0052] In the above embodiment, the orthographic projection of the light shielding layer 14 (including the light shielding area 141 and the plurality of light transmitting areas 142) on the array substrate 11 can cover the border area B1 to enhance the light shielding effect on the border area B1. Figure 2 As shown, the array substrate 11 includes a substrate 111 and a driving circuit layer 112 formed on one side of the substrate 111. The driving circuit layer 112 includes a top metal layer 1120 on the side of the driving circuit layer 112 facing away from the substrate 111. The top metal layer 1120 is used to connect the driving circuit layer 112 with the film layer located on the side of the top metal layer 1120 facing away from the substrate 111. The border area B1 includes a patterned conductive structure. The conductive structure includes a conductive metal strip 1121 located in the display area A1 and located on the top metal layer 1120, metal traces, and conductive traces located in the border area B1. The conductive traces can be arranged around the display area A1 to form a cathode ring 1122. The top metal layer 1120 also includes a metal sealing ring 1123 located in the border area B1 and on the side of the cathode ring 1122 away from the display area A1.

[0053] In the above embodiment, the metal structure is located between the light-emitting layer 12 and the substrate 111. The metal structure includes part or all of the metal traces, the cathode ring 1122, and the metal sealing ring 1123. The display panel 1 also includes a cathode 24 located on the side of the light-emitting layer 12 facing away from the array substrate 11. The cathode 24 can be connected to the cathode ring 1122 in the frame area B1, and the cathode ring 1122 is used to supply power to the cathode 24. The metal traces are used to achieve electrical connections between the structures within the driving circuit. The function of the metal sealing ring 1123 is to prevent cracks generated during the cutting process of the array substrate 11 from spreading toward the display area A1 and to provide electrostatic protection. In the above embodiment, the orthographic projection of the portion of the filter layer 17 located in the frame area B1 on the array substrate 11 can cover the metal structure to achieve better shielding of the metal structure, thereby further reducing the light leakage rate in the frame area B1, thereby improving the yield of the display panel 1.

[0054] like Figure 2As shown, the orthographic projection of the encapsulant 13 on the array substrate 11 is spaced a predetermined distance from the display area A1. The display panel 1 also includes a filler 16 located in the same layer as the encapsulant 13. The filler 16 is partially located in the display area A1 and partially extends into the border area B1. The encapsulant 13 is used to block the filler 16.

[0055] In the above embodiment, the orthographic projection of the light-transmitting area 142 on the array substrate 1 is located within the orthographic projection of the packaging glue 13 on the array substrate 11. On the one hand, the edge of the packaging glue 13 is covered by the light-shielding area 141 to avoid observing the edge of the packaging glue 13 from the light-emitting side of the display panel 1. On the other hand, the part of the orthographic projection of the light-shielding layer 14 on the array substrate 11 that exceeds the orthographic projection of the packaging glue 13 on the array substrate 11 is not provided with the light-transmitting area 142, so that the light-shielding area 141 can effectively shield the area outside the packaging glue 13 in the border area B1.

[0056] In a feasible embodiment, the ratio of the total area of ​​the light-transmitting region 142 to the total area of ​​the light-shielding layer 14 is in a range of 20%-30%.

[0057] In the above embodiment, the total area of ​​the light-shielding layer 14 is the sum of the total area of ​​the light-shielding regions 141 and the total area of ​​the light-transmitting regions 142. By controlling the ratio of the total area of ​​the light-transmitting regions 142 to the total area of ​​the light-shielding layer 14, the light-shielding regions 142 are prevented from being too large, thereby affecting the light-shielding effect of the light-shielding regions 141. At the same time, the light-transmitting regions 142 are prevented from being too small, thereby causing a low light flux for curing the encapsulant 13 and thus affecting the curing effect of the encapsulant 13. Specifically, by setting the ratio of the total area of ​​the light-transmitting regions 142 to the total area of ​​the light-shielding layer 14 within the above ratio range, a balance is achieved between the light-shielding effect of the encapsulation layer 18 and the curing effect of the encapsulant 13.

[0058] In one possible implementation, Figure 2 and Figure 3 As shown, the light-transmitting area 142 includes a plurality of light-transmitting holes 1410 penetrating the light-shielding layer 14 along the thickness direction of the light-shielding layer 14 , and the plurality of light-transmitting holes 1410 are dispersedly arranged.

[0059] In the above embodiment, the light-transmitting area 142 includes a plurality of dispersed light-transmitting holes 1410, so that the area of ​​the light-transmitting area 142 can be dispersed, thereby avoiding the light-transmitting area 142 being concentratedly arranged to cause the area to be too large and affect the light-shielding effect of the light-shielding layer 14 on the frame area B1. The dispersed arrangement of the light-transmitting area 142 can disperse the light passing through the light-shielding layer 14 for curing the packaging glue 13, that is, the positions where the packaging glue 13 receives light are evenly dispersed, so that each position of the packaging glue 13 can achieve a good curing effect.

[0060] Specifically, if Figure 4As shown, the light-transmitting holes 1410 can be arranged in an array, thereby facilitating preparation.

[0061] Specifically, the interval between adjacent light-transmitting holes 1410 ranges from 40 μm to 50 μm.

[0062] Specifically, the spacing between adjacent light-transmitting holes 1410 may be 40 μm, 41 μm, 42 μm, 45 μm, 48 μm, 49 μm, 50 μm, etc., which is not particularly limited in this application.

[0063] In one possible implementation, Figure 5 As shown, the light-transmitting area 142 further includes a light-transmitting material 1411 filled in the light-transmitting hole 1410 .

[0064] In the above embodiment, the light-transmitting area 142 includes a light-transmitting hole 1410 and a light-transmitting material 1411 located in the light-transmitting hole 1410. The light-transmitting material 1411 fills the light-transmitting hole 1410, thereby reducing the step difference in the light-transmitting hole 1410 area, so as to provide a flat supporting surface for subsequent film layers, thereby improving the uniformity and stability of the supporting stress, so as to improve the yield of subsequent film layers.

[0065] In the above embodiment, the light-transmitting material 1411 may be a material with high light transmittance, good flatness, and easy preparation.

[0066] Specifically, the surface of the light-transmitting material 1411 facing away from the array substrate 11 can be flush with the surface of the light-shielding area 141 facing away from the array substrate 11 , so as to achieve a better supporting effect for the upper film layer.

[0067] In a feasible implementation, the transparent material 1411 and the packaging adhesive 13 are made of the same material.

[0068] In the above embodiment, the transparent material 1411 and the encapsulant 13 are made of the same material. This allows the light used to cure the encapsulant 13 to propagate through the same material as it enters the transparent material 1411, thereby achieving a better curing effect. Furthermore, the material used to prepare the transparent material 1411 can be used in conjunction with the encapsulant 13, eliminating the need to replace other materials, thereby simplifying the preparation process.

[0069] In a feasible implementation manner, the outer diameter of the light-transmitting hole 1410 is in a range of 9 μm-11 μm.

[0070] Specifically, the outer diameter of the light-transmitting hole 1410 may be 9 μm, 10 μm, 11 μm, etc., which is not particularly limited in this application.

[0071] Specifically, the shape of the orthographic projection of the light-transmitting hole 1410 on the array substrate 11 is a regular shape such as a circle, a polygon, or an ellipse, so that it is easy to prepare. Figure 3 and Figure 4 When it is circular, as shown in Figure 6 The orthographic projection of the light-transmitting hole 1410 on the array substrate 11 may also be in the shape of a water drop, a gourd, etc., which is not particularly limited in this application.

[0072] Specifically, the polygon may include a triangle, a square, a rhombus, a rectangle, and the like.

[0073] Specifically, the outer diameter of the light-transmitting hole 1410 is the diameter of the circumscribed circle of the orthographic projection of the light-transmitting hole 1410 on the array substrate 11 .

[0074] In one possible implementation, Figure 7 As shown, the portion of the filter layer 17 located in the border area B1 includes an opening 170 , and the orthographic projection of the opening 170 on the array substrate 11 does not overlap with the orthographic projection of the light-transmitting area 142 on the array substrate 11 .

[0075] In the above embodiment, the opening portion 170 is provided in the edge area of ​​the filter layer 17 so that the portion of the filter layer 17 in the border area B1 is a patterned structure, thereby achieving diffuse reflection interception of light, thereby further improving the shading rate of the border area B1.

[0076] In the above embodiment, the plurality of openings 170 are dispersedly arranged to better intercept diffuse reflection of light.

[0077] In the above embodiment, if Figure 8 As shown, the orthographic projection of the opening portion 170 on the array substrate 11 does not overlap with the orthographic projection of the light-transmitting area 142 on the array substrate 11, so that the light-transmitting area 142 in the shading layer 14 and the opening portion 170 in the filter layer 17 are staggered to achieve complementary shading positions, thereby ensuring the shading effect.

[0078] In the above embodiment, the shapes of the orthographic projections of different openings 170 on the array substrate 11 may be the same or different, and this application does not impose any particular limitation on this.

[0079] In the above embodiment, the orthographic projection of the opening 170 on the array substrate 11 is a regular shape such as a circle, polygon, or ellipse, which facilitates fabrication. The orthographic projection of the opening 170 on the array substrate 11 may also be a teardrop shape, a gourd shape, or the like, which is not particularly limited in this application.

[0080] Specifically, the polygon may include a triangle, a square, a rhombus, a rectangle, and the like.

[0081] In one possible implementation, Figure 7 As shown, the filter layer 17 includes a filter function portion, and the multiple filter function portions include a red filter portion 171, a green filter portion 172 and a blue filter portion 173, wherein:

[0082] The portion of the filter layer 17 located in the border area B1 includes a red filter portion 171 or a blue filter portion 173 .

[0083] In the above embodiment, by forming a light filtering functional portion in the border area B1 , the light filtering functional portion can further shield the metal structure, thereby more effectively reducing the reflection of the metal structure.

[0084] In the above embodiment, the display panel 1 may be an OLED display panel 1, the light-emitting layer 12 may include a red light-emitting functional portion, a green light-emitting functional portion, and a blue light-emitting functional portion, and the multiple filter functional portions include a red filter portion 171, a green filter portion 172, and a blue filter portion 173. The red filter portion 171 located in the display area A1 corresponds to the red light-emitting functional portion, that is, the orthographic projection of the red filter portion 171 on the array substrate 11 overlaps the orthographic projection of the red light-emitting functional portion on the array substrate 11. The green filter portion 172 located in the display area A1 corresponds to the green light-emitting functional portion, that is, the orthographic projection of the green filter portion 172 on the array substrate 11 overlaps the orthographic projection of the green light-emitting functional portion on the array substrate 11. The blue filter portion 173 located in the display area A1 corresponds to the blue light-emitting functional portion, that is, the orthographic projection of the blue filter portion 173 on the array substrate 11 overlaps the orthographic projection of the blue light-emitting functional portion on the array substrate 11.

[0085] Specifically, the red filter portion 171 and the blue filter portion 173 have a higher light-shielding rate than the green filter portion 172. Therefore, when the portion of the filter layer 17 located in the border area B1 includes only one filter function portion, it can include only the red filter portion 171 or the blue filter portion 173. This improves the light-shielding rate of the border area B1 and reduces the probability of light reflected from the film layer below the filter layer 17 being emitted through the light-emitting surface of the display panel 1, thereby effectively alleviating light leakage from the border area B1 of the display panel 1. Furthermore, when the portion of the filter layer 17 located in the border area B1 includes only one filter function portion, the thickness of the display panel 1 can be reduced, thereby contributing to a thinner and lighter display panel 1.

[0086] In another possible embodiment, Figure 9 and Figure 10 As shown, the filter layer 17 includes a filter function portion, and the multiple filter function portions include a red filter portion 171, a green filter portion 172 and a blue filter portion 173, wherein:

[0087] The portion of the filter layer 17 located in the border area B1 includes multiple layers of filter portions arranged in a direction away from the array substrate 11 , and the multiple layers of filter portions have different colors.

[0088] In the above embodiment, a plurality of filter function parts can be superimposed on the border area B1 of the actual panel to improve the light shielding rate of the border area B1 of the display panel 1, thereby reducing the probability of light reflected by the film layer below the filter layer 17 being emitted through the light-emitting surface of the display panel 1, thereby effectively improving the problem of light leakage in the border area B1 of the display panel 1.

[0089] The multilayer filter function portion may include two stacked filter function portions, specifically, a red filter portion 171 and a blue filter portion 173 , or a red filter portion 171 and a green filter portion 172 , or a blue filter portion 173 and a green filter portion 172 .

[0090] The multi-layer filter function portion may include three layers of filter function portions stacked together. Specifically, it may include a red filter portion 171, a blue filter portion 173, and a green filter portion 172. The upper and lower positions of the red filter portion 171, the blue filter portion 173, and the green filter portion 172 are not particularly limited in this application. For example: Figure 9 As shown, the multi-layer filter function portion includes a blue filter portion 173 and a red filter portion 171 stacked in sequence in a direction away from the substrate, or as shown in FIG. Figure 10 As shown, the multi-layer filter function portion includes a red filter portion 171 and a blue filter portion 173 which are sequentially stacked in a direction away from the substrate.

[0091] In one possible implementation, Figure 11 As shown, the opening 170 penetrates the multi-layer filter portions arranged in a direction away from the array substrate 11 .

[0092] In the above embodiment, when the portion of the filter layer 17 located in the border region B1 includes multiple layers of filter functional portions stacked in a direction away from the array substrate 11, openings 170 may be formed in the stacked layers of filter functional portions. Openings 170 extend through the stacked layers of filter functional portions. The provision of openings 170 provides a patterned structure in the portion of the filter layer 17 located in the border region B1, thereby achieving diffuse reflection interception of light and further improving the light shielding efficiency of the border region B1.

[0093] In the above embodiment, the plurality of openings 170 are dispersedly arranged to better intercept diffuse reflection of light.

[0094] In the above embodiment, the orthographic projection of the opening portion 170 on the array substrate 11 does not overlap with the orthographic projection of the light-transmitting area 142 on the array substrate 11, so that the light-transmitting area 142 in the shading layer 14 and the opening portion 170 in the filter layer 17 are staggered to achieve complementary shading positions, thereby ensuring the shading effect.

[0097] Specifically, the material of the first encapsulation layer 181 may be silicon nitride, the material of the second encapsulation layer 182 may include aluminum oxide, and the material of the third encapsulation layer 183 may be silicon nitride.

[0098] The orthographic projection of the encapsulation layer 18 on the array substrate 11 covers the array substrate 11 .

[0100] In the display panel 1 , the filter layer 17 may be located on a surface of the first planar layer 20 facing away from the array substrate 11 .

[0101] The display panel 1 further includes a second flat layer 21 . The second flat layer 21 includes one organic layer or two organic layers stacked in a direction away from the array substrate. The second flat layer 21 is located on a surface of the filter layer 17 facing away from the array substrate 11 .

[0102] The display panel 1 also includes a light regulation layer, which can be located on the surface of the second flat layer 21 on the side away from the array substrate 11. The light regulation layer includes optical regulation parts 22 arranged at intervals. The optical regulation parts 22 can regulate the large-angle light emitted by the light-emitting unit, thereby improving the light output rate of the display panel 1.
