[0057] Embodiments of the display panel and the display device are described below with reference to the accompanying drawings.

[0058] Please refer to Figures 1 to 3 , Figure 1 is a partial structure schematic diagram of an isolation structure, an encapsulation part and a light emitting unit in a display panel provided by embodiments of the present application; Figure 2 is a partial structure schematic diagram of an isolation structure, an encapsulation part and a first electrode in a display panel provided by embodiments of the present application; Figure 3 is Figure 1 is a sectional view of A-A in

[0059] As Figures 1 to 3As shown, a first aspect embodiment of this application provides a display panel, which includes a substrate 1, a first electrode layer 61, an isolation structure 2, a light-emitting layer 3, and a first encapsulation layer 4; the first electrode layer 61 is located on one side of the substrate 1 and includes a plurality of first electrodes 611 spaced apart; the isolation structure 2 is located on one side of the substrate 1 and forms a plurality of isolation openings 20, the orthographic projection of the isolation openings 20 on the substrate 1 and the orthographic projection of the first electrodes 611 on the substrate 1 at least partially overlap; the light-emitting layer 3 includes light-emitting units 31 located in each isolation opening 20; the first encapsulation layer 4 includes a plurality of encapsulation portions 40 for encapsulating each light-emitting unit 31; wherein, at least partially, the orthographic projections of two encapsulation portions 40 corresponding to at least two adjacent light-emitting units 31 on the substrate 1 at least partially overlap, and at least partially, the boundary of the orthographic projection of the first electrodes 611 on the substrate 1 is located within the orthographic projection of the encapsulation portions 40 on the substrate 1.

[0060] Optionally, at least a portion of the boundary of the orthographic projection of the first electrode 611 onto the substrate 1 lies within the orthographic projection of the encapsulation portion 40 onto the substrate 1. This can be understood as follows: each light-emitting unit 31 is correspondingly provided with a first electrode 611 and an encapsulation portion 40, and at least a portion of the boundary of the orthographic projection of the first electrode 611 onto the substrate 1 lies within the orthographic projection of the encapsulation portion 40 onto the substrate 1. The orthographic projection of the first electrode 611 onto the substrate 1 can be circular, rectangular, polygonal, or irregular in shape. The orthographic projection of the first electrode 611 can be partially or entirely within the orthographic projection of the encapsulation portion 40 onto the substrate 1. This embodiment uses a rectangular orthographic projection of the first electrode 611 onto the substrate 1 as an example.

[0061] Optionally, the orthographic projection of the first electrode 611 on the substrate 1 is located within the orthographic projection of the package portion 40 on the substrate 1.

[0062] Figure 1 and Figure 2 The location of the packaging section 40 is indicated by a dashed line. The dashed line does not constitute a limitation on the structure of this application. The dashed line is used to define the location and distribution range of the packaging section 40.

[0063] In a display panel provided in this application embodiment, the display panel includes a substrate 1, a first electrode layer 61, an isolation structure 2, a light-emitting layer 3, and a first encapsulation layer 4. The first electrode layer 61 is disposed on one side of the substrate 1 and includes at least two spaced-apart first electrodes 611. The isolation structure 2 is disposed on one side of the substrate 1 and has an isolation opening 20. The light-emitting layer 3 includes light-emitting units 31 disposed on the side of the first electrodes 611 away from the substrate 1 and located within the isolation opening 20. The isolation structure 2 can be used to divide the sub-pixels of the display panel. The isolation structure 2 is disposed on the substrate 1 and forms a plurality of isolation openings 20 to isolate the light-emitting layer 3 to form mutually disconnected light-emitting units 31, thereby reducing crosstalk of charge carriers in the light-emitting layer 3, improving the display effect of the display panel, and eliminating the need for a precision mask in the fabrication of the light-emitting units 31, thus reducing the development and use of precision masks and lowering the manufacturing cost. The first encapsulation layer 4 includes an encapsulation portion 40 for encapsulating each light-emitting unit 31. The encapsulation portion 40 provides encapsulation protection to the light-emitting unit 31, achieving independent encapsulation and improving the yield of the light-emitting unit 31 affected by water and oxygen intrusion. The orthographic projections of the encapsulation portions 40 corresponding to at least two adjacent light-emitting units 31 on the substrate 1 at least partially overlap, and the orthographic projections of the encapsulation portions 40 on the substrate 1 can relatively completely cover the orthographic projection of the first electrode 611 on the substrate 1, resulting in a larger distribution area of ​​the encapsulation portions 40. The overlap of some adjacent encapsulation portions 40 can expand the distribution area of ​​the encapsulation portions 40 and improve the encapsulation effect. Furthermore, at least one encapsulation portion 40 is covered by other encapsulation portions 40, making the relative position between the covered encapsulation portion 40 and the isolation structure 2 more stable. The covered encapsulation portion 40 is less prone to damage, which can further improve the yield and performance of the display panel.

[0064] The composition and preparation of the isolation structure 2 are further described in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, and PCT / CN2024 / 099072 for reference.

[0065] Optionally, multiple isolation openings 20 are spaced apart along the row and column directions, and the direction from one isolation opening 20 to the next is the row or column direction. For example... Figure 1 As shown, the row direction can be the first direction X, and the column direction can be the second direction Y. For example... Figure 3 As shown, the thickness direction of the display panel can be the third direction Z.

[0066] Optionally, adjacent light-emitting units 31 may have different colors. For example, the light-emitting units 31 may have three colors: red, green, and blue. In the row direction, the red, green, and blue light-emitting units 31 are arranged sequentially, while in adjacent row directions, light-emitting units 31 of the same color are staggered, thereby improving the display stripe phenomenon of the display panel and enhancing the display effect.

[0067] Optional, refer to Figure 3 The display panel also includes a second encapsulation layer 5 and a third encapsulation layer 8 disposed on the side of the first encapsulation layer 4 facing away from the substrate 11. The material of the second encapsulation layer 5 may include organic materials to give the second encapsulation layer 5 good fluidity and make the surface of the second encapsulation layer 5 facing away from the substrate 1 relatively flat. The material of the third encapsulation layer 8 may include inorganic materials to further improve the encapsulation effect of the display panel.

[0068] Optionally, the display panel also includes a touch layer, a polarizing layer, and a cover plate disposed on the third encapsulation layer 8. The touch layer is used to enable touch operation of the display panel, the polarizing layer is used to filter light to improve the display effect of the display panel, and the cover plate is used to protect the underlying film layer to improve the strength of the display panel.

[0069] In some alternative embodiments, refer to Figure 3 The display panel also includes a second electrode layer 62, which includes a second electrode 621 located between the light-emitting unit 31 and the encapsulation portion 40. One of the first electrode 611 and the second electrode 621 can serve as an anode, and the other can serve as a cathode to drive the light-emitting unit 31 to emit light. In this embodiment, the first electrode 611 is used as the anode of the display panel, and the second electrode 621 is used as the cathode of the display panel for illustrative purposes.

[0070] In some alternative embodiments, refer to Figure 3 The material of the isolation structure 2 includes a conductive material, and the second electrode 621 is electrically connected to the isolation structure 2. The isolation structure 2 separates the second electrode layer 62 to form mutually spaced second electrodes 621. The mutually spaced second electrodes 621 are electrically connected through the isolation structure 2 to form a full-surface electrode, ensuring the normal light emission of the light-emitting unit 31.

[0071] In some alternative embodiments, refer to Figure 3The display panel also includes a pixel definition layer 7 located on one side of the substrate 1. The pixel definition layer 7 includes a pixel limiting portion 71 and a pixel opening 72. The pixel opening 72 is connected to an isolation opening 20, and the pixel opening 72 is used to accommodate the light-emitting unit 31. The isolation structure 2 is located on the side of the pixel limiting portion 71 facing away from the substrate 1, or the pixel limiting portion 71 has an accommodating opening, and the isolation structure 2 is located within the accommodating opening. This embodiment of the application illustrates the example where the isolation structure 2 is located on the pixel limiting portion 71. The first electrode 611 and the isolation structure 2 are insulated from each other through the pixel limiting portion 71, making it less likely for the second electrode 621 to short-circuit with the first electrode 611 through the isolation structure 2, thereby improving the operational stability of the display panel.

[0072] Optionally, the orthographic projection of the pixel opening 72 on the substrate 1 is located within the orthographic projection of the isolation opening 20 on the substrate 1, at least a portion of the light-emitting unit 31 is located within the pixel opening 72, and a portion of the first electrode 611 is exposed from the pixel opening 72 to contact at least a portion of the light-emitting unit 31, so that the light-emitting unit 31 can be connected to the first electrode 611 through the pixel opening 72, so that the first electrode 611 can drive the light-emitting unit 31 to emit light for display.

[0073] In some alternative embodiments, refer to Figure 3 Of the two adjacent encapsulation portions 40, one is a first encapsulation portion 41 and the other is a second encapsulation portion 42. The first encapsulation portion 41 includes a first segment 411 and a second segment 412. The first segment 411 is located on the side of the light-emitting unit 31 away from the substrate 1 and extends to the sidewall of the isolation structure 2 facing the isolation opening 20. The second segment 412 is located on the side of the isolation structure 2 away from the substrate 1. The second encapsulation portion 42 includes a third segment 421 and a fourth segment 422. The third segment 421 is located on the side of the light-emitting unit 31 away from the substrate 1 and extends to the sidewall of the isolation structure 2 facing the isolation opening 20. The fourth segment 422 is located on the side of the isolation structure 2 away from the substrate 1. The orthographic projection of the second segment 412 on the substrate 1 and the orthographic projection of the fourth segment 422 on the substrate 1 at least partially overlap.

[0074] In these embodiments, the encapsulation portion 40 covers the sidewall of the isolation structure 2 facing the isolation opening 20 and extends to the side of the isolation structure 2 away from the substrate 1. That is, the encapsulation portion 40 not only covers the isolation opening 20, but also covers a portion of the isolation structure 2 surrounding the isolation opening 20, which can expand the distribution area of ​​the encapsulation portion 40 and improve the encapsulation effect of the encapsulation portion 40. The second segment 412 and the fourth segment 422 extend on the isolation structure 2 toward the adjacent light-emitting unit 31, and their orthographic projections at least partially overlap. This overlap can be that the second segment 412 is stacked on the side of the fourth segment 422 away from the substrate 1, or the fourth segment 422 is stacked on the side of the second segment 412 away from the substrate 1. In this embodiment, the fourth segment 422 is stacked on the side of the second segment 412 away from the substrate 1 for example. The first encapsulation portion 41 includes a first segment 411 and a second segment 412. The second segment 412 covers a portion of the isolation structure 2 to expand the distribution area of ​​the first encapsulation portion 41. The second encapsulation portion 42 includes a third segment 421 and a fourth segment 422. The fourth segment 422 covers the isolation structure 2 to expand the distribution area of ​​the second encapsulation portion 42. Both the second segment 412 and the fourth segment 422 are located on the top surface 23 of the isolation structure 2. The orthographic projections of the second segment 412 and the fourth segment 422 on the isolation structure 2 at least partially overlap, so that the fourth segment 422 can cover part of the second segment 412. On the one hand, this expands the distribution area of ​​the second encapsulation portion 42 and improves the encapsulation effect of the second encapsulation portion 42. On the other hand, since part of the first encapsulation portion 41 is covered by the second encapsulation portion 42, the stability of the relative position between the first encapsulation portion 41 and the isolation structure 2 can be improved, mitigating the problem of encapsulation failure caused by damage to the second segment 412.

[0075] Optionally, the edges of the orthographic projections of the second segment 412 and / or the fourth segment 422 on the substrate 1 are at least partially located within the orthographic projection of the isolation structure 2 on the substrate 1. By setting the edges of the orthographic projections of the second segment 412 on the substrate 1 to be partially or entirely located within the orthographic projection of the isolation structure 2 on the substrate 1, the second segment 412 can extend a certain distance towards the adjacent light-emitting unit 31 in all directions, thereby increasing the distribution area of ​​the first encapsulation portion 41, expanding the distribution area of ​​the first encapsulation portion 41, and improving the encapsulation effect. The fourth segment 422 is similar and will not be described in detail here.

[0076] Figure 4 This is one of the partial cross-sectional views of a display panel provided in the embodiments of this application.

[0077] In some alternative embodiments, refer to Figure 3 and Figure 4The plurality of first electrodes 611 include a first sub-electrode 6111 corresponding to the first package portion 41 and a second sub-electrode 6112 corresponding to the second package portion 42. The first sub-electrode 6111 is located on the side of the first package portion 41 facing the substrate 1, and the second sub-electrode 6112 is located on the side of the second package portion 42 facing the substrate 1. The edge portion of the first sub-electrode 6111 in the orthographic projection of the substrate 1 is located within the orthographic projection of the second segment 412 on the substrate 1. And / or, the edge portion of the second sub-electrode 6112 in the orthographic projection of the substrate 1 is located within the orthographic projection of the fourth segment 422 on the substrate 1.

[0078] The first sub-electrode 6111 corresponding to the first encapsulation part 41 can be understood as the first encapsulation part 41 encapsulating one light-emitting unit 31, and the first sub-electrode 6111 being electrically connected to the light-emitting unit 31. The second sub-electrode 6112 corresponding to the second encapsulation part 42 can be understood as the first encapsulation part 41 encapsulating another light-emitting unit 31, and the second sub-electrode 6112 being electrically connected to the other light-emitting unit 31.

[0079] In these embodiments, by extending the boundary of the first sub-electrode 6111 below the second segment 412, the first sub-electrode 6111 can have a sufficiently large area, thereby increasing the size of the pixel opening 72 on the first sub-electrode 6111. This results in a larger area for the light-emitting unit 31 disposed within the pixel opening 72, increasing the proportion of the light-emitting area of ​​the display panel and improving the display effect. Furthermore, the first sub-electrode 6111 extending below the second segment 412 is also located on the side of the pixel limiting portion 71 facing the substrate 1, away from the pixel opening 72. This location allows for the placement of vias connecting the first sub-electrode 6111 to the thin-film transistor (TFT), reducing the impact of unevenness caused by the vias on the light emission of the light-emitting unit 31. The placement of the second sub-electrode 6112 is similar and will not be described further here.

[0080] Optionally, the fourth segment 422 includes a first sub-segment 4221 and a second sub-segment 4222. The first sub-segment 4221 is connected between the third segment 421 and the second sub-segment 4222, and the second sub-segment 4222 is located on the side of the second segment 412 facing away from the substrate 1. The fourth segment 422 extends along a bending path, with a portion of the fourth segment 422 (i.e., the second sub-segment 4222) located on the second segment 412, and another portion of the fourth segment 422 (i.e., the first sub-segment 4221) and the second segment 412 arranged side by side.

[0081] Optionally, the second sub-segment 4222 is connected to the periphery of the first sub-segment 4221 away from the third segment 421, that is, the second sub-segment 4222 is connected to the edge of the first sub-segment 4221 away from the third segment 421. For example, Figure 4The dashed line M in the middle represents the boundary between the first sub-segment 4221 and the second sub-segment 4222.

[0082] Optionally, the second sub-segment 4222 and the second segment 412 are spaced apart along the thickness direction of the display panel to form a first gap Q1. During the fabrication of the second encapsulation portion 42, a second light-emitting material layer is covered under the second encapsulation material layer, and this portion of the second light-emitting material layer is subsequently etched away to form the first gap Q1.

[0083] Optionally, the second segment 412 and the second sub-layer 22 are spaced apart along the thickness direction of the display panel to form a second gap Q2. During the fabrication of the first encapsulation portion 41, a first light-emitting material layer is covered under the first encapsulation material layer, and this portion of the first light-emitting material layer is subsequently etched away to form the second gap Q2.

[0084] Optionally, the first sub-segment 4221 and the second sub-layer 22 are spaced apart along the thickness direction of the display panel to form a third gap Q3. That is, the third gap Q3 is formed when the second light-emitting material layer between the first sub-segment 4221 and the isolation structure 2 is removed.

[0085] In some alternative embodiments, refer to Figure 4 The edge of the second sub-electrode 6112 in the orthographic projection of the substrate 1 is located within the orthographic projection of the first sub-segment 4221 on the substrate 1. The edge of the second sub-electrode 6112 in the orthographic projection of the substrate 1 can be partially located within the orthographic projection of the first sub-segment 4221 of the fourth segment 422 on the substrate 1, thereby maintaining a certain distance from the first sub-electrode 6111.

[0086] In some other embodiments, the edge of the second sub-electrode 6112 in the orthographic projection of the substrate 1 may also be partially located within the orthographic projection of the second sub-segment 4222 of the fourth segment 422 on the substrate 1.

[0087] Optionally, the edge of the second sub-electrode 6112 in the orthographic projection of the substrate 1 may be partially located within the orthographic projection of the second segment 412 on the substrate 1 (not shown). That is, part of the second segment 412 extends directly above the second sub-electrode 6112 corresponding to the adjacent light-emitting unit 31, further expanding the distribution area of ​​the first encapsulation portion 41 and improving the encapsulation effect.

[0088] Alternatively, as... Figure 4 As shown, the orthographic projection of the second sub-electrode 6112 onto the substrate 1 and the orthographic projection of the second segment 412 onto the substrate 1 can also be arranged alternately.

[0089] In some alternative embodiments, such as Figure 4As shown, the edge portion of the first sub-electrode 6111 in the orthographic projection of the substrate 1 is located within the orthographic projection of the second sub-segment 4222 on the substrate. That is, a portion of the second sub-segment 4222 extends directly above the first sub-electrode 6111 corresponding to the adjacent light-emitting unit 31, further expanding the distribution area of ​​the second encapsulation portion 42 and improving the encapsulation effect.

[0090] In some alternative embodiments, refer to Figure 4 The display panel further includes a second encapsulation layer 5; the second encapsulation layer 5 is disposed on the side of the first encapsulation layer 4 facing away from the substrate 1, and at least one encapsulation portion 40 forms a gap with its adjacent encapsulation portion 40 and the isolation structure 2, and the second encapsulation layer 5 fills at least part of the gap. The gap may include at least one of a first gap Q1, a second gap Q2, and a third gap Q3, that is, the second encapsulation layer 5 fills at least one of the first gap Q1, the second gap Q2, and the third gap Q3.

[0091] Optionally, the second encapsulation layer 5 is at least partially filled into the first gap Q1; and / or: the second encapsulation layer 5 is at least partially filled into the second gap Q2; and / or: the second encapsulation layer 5 is at least partially filled into the third gap Q3, such that the second encapsulation layer 5 can provide support to the first sub-segment 4221, the second sub-segment 4222, or the second segment 412.

[0092] In some alternative embodiments, refer to Figure 3 and Figure 4 The isolation structure 2 includes a first sublayer 21 and a second sublayer 22 stacked along a direction away from the substrate 1. The orthographic projection of the first sublayer 21 onto the substrate 1 is located within the orthographic projection of the second sublayer 22 onto the substrate 1.

[0093] In these embodiments, by positioning the orthographic projection of the first sublayer 21 onto the substrate 1 within the orthographic projection of the second sublayer 22 onto the substrate 1, i.e., the second sublayer 22 protruding from the first sublayer 21 toward the isolation opening 20, the second sublayer 22 can shield at least part of the material used to prepare the light-emitting layer 3 and the second electrode layer 62 when the light-emitting layer 3 and the second electrode layer 62 of the display panel are deposited, thereby isolating the light-emitting layer 3 and the second electrode layer 62 between adjacent sub-pixels. This facilitates the formation of multiple spaced light-emitting units 31 located within the isolation opening 20 and multiple spaced second electrodes 621 located within the isolation opening 20. As a result, it is not necessary to set a high-precision mask when depositing the light-emitting layer 3 and the second electrode layer 62 of the display panel. For example, it is not necessary to set a high-precision fine metal mask (FMM) when depositing the light-emitting layer 3 and the second electrode layer 62, thereby significantly reducing the manufacturing cost of the display panel.

[0094] Optionally, the orthographic projections of the second segment 412, the fourth segment 422, and the second sublayer 22 on the substrate 1 at least partially overlap. That is, the orthographic projections of the second segment 412, the fourth segment 422, and the second sublayer 22 on the substrate 1 have a common overlapping portion, which expands the distribution area of ​​the encapsulation portion 40 and improves the encapsulation effect of the encapsulation portion 40.

[0095] Optionally, the edges of the orthographic projections of the second segment 412 and / or the fourth segment 422 on the substrate 1 are at least partially located within the orthographic projection of the first sublayer 21 on the substrate 1. The edges of the orthographic projections of the second segment 412 and / or the fourth segment 422 on the substrate 1 may be partially located within the orthographic projection of the first sublayer 21 on the substrate 1, or they may be entirely located within the orthographic projection of the first sublayer 21 on the substrate 1. This allows the second segment 412 and / or the fourth segment 422 to extend a longer distance towards the adjacent light-emitting unit 31 in each direction, further improving the encapsulation effect.

[0096] Figure 5 This is a second partial cross-sectional view of a display panel provided in an embodiment of this application.

[0097] In some alternative embodiments, refer to Figure 5 The isolation structure 2 further includes a third sub-layer 24, which is disposed on the side of the first sub-layer 21 facing the substrate 1. The third sub-layer 24 protrudes from the first sub-layer 21 toward the isolation opening 20. Optionally, the material of the third sub-layer 24 may include a conductive material. The second electrode 621 can be connected to the third sub-layer 24, so that the second electrodes 621 of adjacent sub-pixels can be electrically connected through the third sub-layer 24. By setting the third sub-layer 24 to protrude from the first sub-layer 21 toward the isolation opening 20, the third sub-layer 24 can have a larger size to facilitate connection with the second electrode 621.

[0098] Figure 6 This is a third partial cross-sectional view of a display panel provided in an embodiment of this application; Figure 7 This is a fourth partial cross-sectional view of a display panel provided in an embodiment of this application.

[0099] Combined with reference Figures 1 to 7An embodiment of the first aspect of this application also provides a display panel, including a substrate 1, a first electrode layer 61, an isolation structure 2, a light-emitting layer 3, and a first encapsulation layer 4; the first electrode layer 61 is located on one side of the substrate 1 and includes a plurality of first electrodes 611 spaced apart; the isolation structure 2 is located on one side of the substrate 1, the isolation structure 2 encloses to form a plurality of isolation openings 20 and has a top surface 23 facing away from the substrate 1, the orthographic projection of the isolation openings 20 on the substrate 1 and the orthographic projection of the first electrodes 611 on the substrate 1 at least partially overlap; the light-emitting layer 3 includes light-emitting units 31 located in each isolation opening 20; the first encapsulation layer 4 includes a plurality of encapsulation portions 40 for encapsulating each light-emitting unit 31; wherein, the orthographic projection of the encapsulation portion 40 on the substrate 1 and the orthographic projection of the top surface 23 on the substrate 1 at least partially overlap, and at least a portion of the boundary of the orthographic projection of the first electrode 611 on the substrate 1 corresponding to at least one light-emitting unit 31 is located within the orthographic projection of the encapsulation portion 40 on the substrate 1.

[0100] Optionally, corresponding to at least one light-emitting unit 31, at least a portion of the boundary of the orthographic projection of the first electrode 611 onto the substrate 1 is located within the orthographic projection of the encapsulation portion 40 onto the substrate 1. This can be understood as follows: each light-emitting unit 31 is correspondingly provided with a first electrode 611 and an encapsulation portion 40, and at least a portion of the boundary of the orthographic projection of the first electrode 611 onto the substrate 1 is located within the orthographic projection of the encapsulation portion 40 onto the substrate 1. The orthographic projection of the first electrode 611 onto the substrate 1 can be circular, rectangular, polygonal, or irregular in shape, and its orthographic projection can be partially or entirely located within the orthographic projection of the encapsulation portion 40 onto the substrate 1.

[0101] Optionally, the orthographic projection of the first electrode 611 on the substrate 1 is located within the orthographic projection of the package portion 40 on the substrate 1.

[0102] In a display panel provided in this application embodiment, the display panel includes a substrate 1, a first electrode layer 61, an isolation structure 2, a light-emitting layer 3, and a first encapsulation layer 4. The first electrode layer 61 is disposed on one side of the substrate 1 and includes at least two spaced-apart first electrodes 611. The isolation structure 2 is disposed on one side of the substrate 1 and has an isolation opening 20. The light-emitting layer 3 includes light-emitting units 31 disposed on the side of the first electrodes 611 away from the substrate 1 and located within the isolation opening 20. The isolation structure 2 can be used to divide the sub-pixels of the display panel. The isolation structure 2 is disposed on the substrate 1 and forms a plurality of isolation openings 20 to isolate the light-emitting layer 3 to form mutually disconnected light-emitting units 31, thereby reducing crosstalk of charge carriers in the light-emitting layer 3, improving the display effect of the display panel, and eliminating the need for a precision mask in the fabrication of the light-emitting units 31, thus reducing the development and use of precision masks and lowering the manufacturing cost. The first encapsulation layer 4 includes an encapsulation portion 40 for encapsulating each light-emitting unit 31. The encapsulation portion 40 provides encapsulation protection to the light-emitting unit 31, achieving independent encapsulation and improving the yield of the light-emitting unit 31 affected by water and oxygen intrusion. The encapsulation portion 40 extends on the top surface 23 to adjacent light-emitting units 31. The orthographic projection of the encapsulation portion 40 on the substrate 1 at least partially overlaps with the orthographic projection of the top surface 23 on the substrate 1. Furthermore, the orthographic projection of the encapsulation portion 40 on the substrate 1 can relatively completely cover the orthographic projection of the first electrode 611 on the substrate 1, resulting in a larger distribution area of ​​the encapsulation portion 40. This expands the distribution area of ​​the encapsulation portion 40, improves the encapsulation effect, and thereby improves the yield and performance of the display panel.

[0103] Optional, such as Figure 6 As shown, the orthographic projections of two adjacent package portions 40 onto the substrate 1 can be spaced apart; as... Figure 4 and Figure 5 As shown, the orthographic projections of two adjacent package portions 40 onto the substrate 1 can also overlap; as...
