Description

Technical Field

[0001] This application belongs to the field of display device technology, and in particular relates to a display panel and display device. Background Technology

[0002] With the development of display technology, OLED (Organic Light Emitting Diode) display panels have been widely used due to their advantages such as being thinner and lighter, brighter, having lower power consumption, faster response, and higher resolution.

[0003] During the manufacturing process of display panels using related technologies, dark spots may appear in the light-emitting units, affecting the display effect. Summary of the Invention

[0004] In view of this, embodiments of this application provide a display panel and a display device to solve the problem that dark spots exist in the light-emitting units of current display panels, affecting the display effect.

[0005] A first aspect of this application provides a display panel, comprising: a substrate, an insulating layer, a light-emitting layer, an isolation structure, and a protective layer. The insulating layer and the light-emitting layer are sequentially stacked on one side of the substrate. The light-emitting layer includes a plurality of light-emitting units spaced apart from each other. The isolation structure is disposed on the side of the insulating layer away from the substrate, and the isolation structure is located between at least partially adjacent two light-emitting units. Each light-emitting unit includes a first electrode. The insulating layer includes a via. The first electrode passes through at least partially through the via. At least a portion of the orthographic projection of the via on the substrate is located within the orthographic projection of the isolation structure on the substrate. The protective layer is disposed on the side of the insulating layer away from the substrate, and the orthographic projection of the via on the substrate is located within the orthographic projection of the protective layer on the substrate.

[0006] The aforementioned display panel, by placing at least a portion of the vias on the substrate within the orthogonal projection of the isolation structure on the substrate, and by placing the vias on the substrate within the orthogonal projection of the protective layer on the substrate, effectively positions the vias below the protective layer and the isolation structure. This allows the protective layer and the isolation structure to jointly protect the vias. During the manufacturing process of the display panel, under the joint protection of the protective layer and the isolation structure, the first electrode in the via will not be exposed due to over-etching, thus preventing damage to the light-emitting unit during manufacturing and avoiding the problem of dark spots in the light-emitting unit, thereby improving the display effect of the display panel.

[0007] In one embodiment, the isolation structure includes at least two sub-isolation structures and at least one notch, the notch being located between at least partially adjacent sub-isolation structures; at least a portion of the via's orthographic projection on the substrate lies within the orthographic projection of the notch on the substrate. By ensuring that at least a portion of the via's orthographic projection on the substrate lies within the orthographic projection of the notch in the isolation structure on the substrate, i.e., by placing the via below the notch between two adjacent sub-isolation structures in the isolation structure, it facilitates both the processing and installation of the via and the isolation structure, and also facilitates the application of a protective layer to protect the via.

[0008] In one embodiment, the light-emitting unit includes a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit, and the via includes a first via, a second via, and a third via. A first electrode in the first light-emitting unit is at least partially disposed through the first via, a first electrode in the second light-emitting unit is at least partially disposed through the second via, and a first electrode in the third light-emitting unit is at least partially disposed through the third via.

[0009] In one embodiment, at least two of the first via, the second via, and the third via have their orthographic projections on the substrate located within the orthographic projection of the same notch on the substrate. Positioning at least two of the first via, the second via, and the third via below the notch between two adjacent sub-isolation structures within the same isolation structure facilitates the application of a protective layer at the notch location for centralized protection of the vias.

[0010] In one embodiment, the light-emitting unit further includes a second electrode and a light-emitting functional part. The second electrode is disposed opposite to and spaced apart from the first electrode, and the light-emitting functional part is disposed between the first electrode and the second electrode. The protective layer includes the second electrode and the light-emitting functional part. By including the second electrode and the light-emitting functional part in the protective layer, the fabrication of the protective layer does not require additional steps and can be fabricated together with the second electrode and the light-emitting functional part in the light-emitting unit, thereby reducing the difficulty of the manufacturing process and lowering the processing cost.

[0011] In one embodiment, the display panel further includes a pixel defining layer disposed on the side of the insulating layer opposite to the substrate. The pixel defining layer defines a plurality of pixel openings spaced apart from each other, and the light-emitting unit is at least partially located within the pixel openings. The isolation structure is disposed on the side of the pixel defining layer away from the substrate. By providing the pixel defining layer and the pixel openings defined by the pixel defining layer, at least part of the light-emitting unit is disposed within the pixel openings, and the isolation structure is disposed on the pixel defining layer, which facilitates the forming of the light-emitting unit and the isolation structure.

[0012] In one embodiment, the display panel further includes an encapsulation layer disposed on the side of the light-emitting layer opposite to the substrate, and the protective layer includes the encapsulation layer. By including the encapsulation layer in the protective layer, the production of the protective layer does not require additional steps and can be formed together with the encapsulation layer. The encapsulation layer not only encapsulates and protects the entire display panel but also protects the first electrode in the via.

[0013] In one embodiment, the isolation structure includes an isolator and a blocking portion. The blocking portion is located on the side of the isolator facing away from the substrate, and the orthographic projection of the isolator on the substrate lies within the orthographic projection of the blocking portion on the substrate. The encapsulation layer at least covers the sidewall of the isolator and at least a portion of the surface of the blocking portion facing away from the isolator. By employing the isolation structure designed above, and having the encapsulation layer cover the sidewall of the isolator and at least a portion of the surface of the blocking portion facing away from the isolator, moisture can be effectively blocked, providing good protection for the first electrode in the via of the display panel.

[0014] In one embodiment, the protective layer includes an optical adhesive layer. Using an optical adhesive layer as the protective layer provides better protection and lower cost.

[0015] In one embodiment, the optical adhesive layer is located on the side of the isolation structure away from the substrate, and / or the isolation structure includes at least one notch, and the optical adhesive layer is located within at least one notch.

[0016] A second aspect of this application provides a display panel, comprising: a substrate, an insulating layer, a light-emitting layer, an isolation layer, and a protective layer. The insulating layer and the light-emitting layer are sequentially stacked on one side of the substrate. The light-emitting layer includes a plurality of light-emitting units spaced apart from each other. The isolation layer is disposed on the side of the insulating layer away from the substrate and defines a plurality of first openings. At least a portion of the light-emitting units are located within the first openings. Each light-emitting unit includes a first electrode. The insulating layer includes a via. At least a portion of the first electrode passes through the via. The orthographic projection of at least a portion of the via on the substrate is located within the orthographic projection of the isolation layer on the substrate. The protective layer is disposed on the side of the insulating layer away from the substrate, and the orthographic projection of the via on the substrate is located within the orthographic projection of the protective layer on the substrate.

[0017] The aforementioned display panel, by placing at least a portion of the vias on the substrate within the orthogonal projection of the isolation layer on the substrate, and by placing the vias on the substrate within the orthogonal projection of the protective layer on the substrate, effectively positions the vias below the protective layer and the isolation layer. This allows the protective layer and the isolation layer to jointly protect the vias. During the manufacturing process of the display panel, under the joint protection of the protective layer and the isolation layer, the first electrode in the via will not be exposed due to over-etching, thus preventing damage to the light-emitting unit during manufacturing and avoiding the problem of dark spots in the light-emitting unit, thereby improving the display effect of the display panel.

[0067] To at least partially address the problems in the relevant technologies, see [link / reference]. Figures 1 to 3 As shown, this application embodiment provides a display panel 100, which includes: a substrate 110, an insulating layer 120, a light-emitting layer 130, an isolation structure 140, and a protective layer 150.

[0068] Specifically, an insulating layer 120 and a light-emitting layer 130 are sequentially stacked on one side of a substrate 110. The light-emitting layer 130 includes a plurality of light-emitting units 131 spaced apart from each other. The insulating layer 120 and the light-emitting layer 130 are sequentially stacked on one side of the substrate 110, meaning the insulating layer 120 is located on one side of the substrate 110, and the light-emitting layer 130 is located on the side of the insulating layer 120 facing away from the substrate 110. The substrate 110 is used to support and carry other film layers in the display panel 100. Exemplarily, the substrate 110 can be made of materials such as glass or polyimide (PI). In some embodiments, the substrate 110 may further include an array substrate, on which a driving circuit is provided for driving the light-emitting units 131 in the display area to emit light. Under the drive of the driving circuit, different light-emitting units 131 in the display area can be excited to emit light of different colors, enabling the display panel 100 to achieve a colorful display effect.

[0069] like Figure 1 As shown, the substrate 110 further includes a driving circuit layer 170. Specifically, the driving circuit layer 170 includes a semiconductor layer, a gate, and source / drain electrodes. The semiconductor layer includes an active layer, and the gate is located on one side of the semiconductor layer. The orthographic projection of the gate onto the surface of the semiconductor layer at least partially overlaps with the orthographic projection of the active layer onto the surface of the semiconductor layer. An interlayer insulating layer is provided between the semiconductor layer and the gate. The source / drain electrodes include a source electrode and a drain electrode spaced apart, and the source electrode and drain electrode are connected to the active layer through vias penetrating the interlayer insulating layer.

[0070] An insulating layer 120 is disposed on one side of the substrate 110. In addition to maintaining relative insulation between the film layers located on both sides thereon, the insulating layer 120 may also have other functions. For example, the insulating layer 120 may include a planarization layer to enable the light-emitting layer 130 disposed on the insulating layer 120 to have a high degree of planarization. The light-emitting layer 130 includes a plurality of light-emitting units 131 arranged at intervals between each other. For example, the light-emitting units 131 may be red light-emitting units for emitting red light, green light-emitting units for emitting green light, blue light-emitting units for emitting blue light, or white light-emitting units for emitting white light, etc. The number of different types of light-emitting units 131, the arrangement of the plurality of light-emitting units 131, and the spacing between two adjacent light-emitting units 131 can be flexibly set and are not limited here.

[0071] An isolation structure 140 is disposed on the side of the insulating layer 120 facing away from the substrate 110, and the isolation structure 140 is located between at least partially adjacent two light-emitting units 131. That is, among the plurality of light-emitting units 131, an isolation structure 140 is provided between a portion of two adjacent light-emitting units 131, or an isolation structure 140 is provided between every two adjacent light-emitting units 131. The light emitted by each light-emitting unit 131 is blocked by the isolation structure 140 to prevent interference with the light emitted by its adjacent light-emitting units 131, thus avoiding signal crosstalk between adjacent light-emitting units 131. The specific structural form of the isolation structure 140 is not limited, as long as it can effectively separate two light-emitting units 131.

[0072] The light-emitting unit 131 emits light under the driving action of the driving circuit. Specifically, the light-emitting material in the light-emitting unit 131 emits light under the action of an electric field. The light-emitting unit 131 may include a first electrode 1311. Under the action of the first electrode 1311 and other components, an electric field is generated, thereby causing the light-emitting material in the light-emitting unit 131 to emit light. The insulating layer 120 includes a via 121. The first electrode 1311 is at least partially disposed through the via 121. Through the via 121 on the insulating layer 120, the first electrode 1311 can be connected to the driving circuit or other signal traces of the display panel 100. The shape, size, etc. of the first via 121A are not limited.

[0073] It is understood that the first electrode 1311 in this application may include a connection structure located in the via 121 of the insulating layer 120.

[0074] To prevent the first electrode 1311 in the via 121 from being exposed due to over-etching, which could damage the light-emitting unit 131 during the fabrication of the display panel 100 and cause dark spots in the light-emitting unit 131, in the embodiments of this application, at least a portion of the orthographic projection of the via 121 on the substrate 110 lies within the orthographic projection of the isolation structure 140 on the substrate 110. The protective layer 150 is disposed on the side of the insulating layer 120 facing away from the substrate 110, and the orthographic projection of the via 121 on the substrate 110 lies within the orthographic projection of the protective layer 150 on the substrate 110. For example... Figure 2 As shown, the orthographic projection of the third via 121C on the substrate 110 is located within the orthographic projection of the isolation structure 140 on the substrate 110.

[0075] In other words, at least part of the orthographic projection of the via 121 on the substrate 110 is completely covered by the orthographic projection of the isolation structure 140 on the substrate 110, and is also completely covered by the orthographic projection of the protective layer 150 on the substrate 110. This allows the protective layer 150 and the isolation structure 140 to work together to protect the via 121. During the manufacturing process of the display panel 100, under the joint protection of the protective layer 150 and the isolation structure 140, the first electrode 1311 in the via 121 will not be exposed due to over-etching.

[0076] The display panel 100 of this application embodiment places the orthographic projection of the via 121 on the substrate 110 within the orthographic projection of the isolation structure 140 on the substrate 110, and the orthographic projection of the via 121 on the substrate 110 within the orthographic projection of the protective layer 150 on the substrate 110. That is, the via 121 is placed under the protective layer 150 and the isolation structure 140, so that the protective layer 150 and the isolation structure 140 can jointly protect the via 121. During the manufacturing process of the display panel 100, under the joint protection of the protective layer 150 and the isolation structure 140, the first electrode 1311 in the via 121 will not be exposed due to over-etching, and the light-emitting unit 131 will not be damaged during the manufacturing process, thus avoiding the problem of dark spots in the light-emitting unit 131 and improving the display effect of the display panel 100.

[0077] The specific structural form of the isolation structure 140 is not limited. In some embodiments, the isolation structure 140 can be a single-piece structure in the direction parallel to the surface of the substrate 110, while in other embodiments... Figure 2 In the illustrated embodiment, the isolation structure 140 can also be a split structure. Optionally, the isolation structure 140 includes at least two sub-isolation structures 141 and at least one notch 142. Optionally, each sub-isolation structure 141 can be arranged opposite to each other and spaced apart along a direction parallel to the surface of the substrate 110, and the notch 142 is located between at least partially adjacent two sub-isolation structures 141. That is, the isolation structure 140 is not a completely continuous structure, but has certain breaks at some locations, namely the notch 142. The location, cross-sectional shape, and size of the notch 142 are not limited.

[0078] In this embodiment, at least a portion of the orthographic projection of the via 121 onto the substrate 110 lies within the orthographic projection of the notch 142 onto the substrate 110. For example... Figure 2 As shown, the orthographic projections of the first via 121A and the second via 121B on the substrate 110 are located within the orthographic projection of the notch 142 on the substrate 110.

[0079] By positioning the orthographic projection of the via 121 on the substrate 110 within the orthographic projection of the notch 142 of the isolation structure 140 on the substrate 110, the via 121 is positioned below the notch 142 between two adjacent sub-isolation structures 141 in the isolation structure 140. This facilitates the processing and setting of the via 121 and the isolation structure 140, and also facilitates the setting of the protective layer 150 to protect the via 121.

[0080] As described above, the light-emitting layer 130 may include a plurality of light-emitting units 131 for emitting light of different colors. In some embodiments, optionally, the light-emitting unit 131 includes a first light-emitting unit 131A, a second light-emitting unit 131B, and a third light-emitting unit 131C. The insulating layer 120 also includes a plurality of vias 121 corresponding to different light-emitting units 131. The vias 121 include a first via 121A, a second via 121B, and a third via 121C. The first electrode 1311 in 31A is at least partially inserted through the first via 121A, the first electrode 1311 in the second light-emitting unit 131B is at least partially inserted through the second via 121B, and the first electrode 1311 in the third light-emitting unit 131C is at least partially inserted through the third via 121C; at least two of the first via 121A, the second via 121B, and the third via 121C have their orthogonal projections on the substrate 110 located within the orthogonal projection of the same isolation structure 140 on the substrate 110.

[0081] In this embodiment, as Figure 2 As shown, the first via 121A and the second via 121B can be located within the orthogonal projection of the same isolation structure 140 onto the substrate 110; alternatively, the first via 121A and the third via 121C can be located within the orthogonal projection of the same isolation structure 140 onto the substrate 110; or the second via 121B and the third via 121C can be located within the orthogonal projection of the same isolation structure 140 onto the substrate 110. Figure 3 As shown, the first via 121A, the second via 121B, and the third via 121C can all be located within the orthographic projection of the same isolation structure 140 on the substrate 110. By making at least two of the first via 121A, the second via 121B, and the third via 121C on the substrate 110 within the orthographic projection of the same isolation structure 140 on the substrate 110, the via 121 is positioned more centrally. This not only facilitates the manufacturing of the display panel 100 but also provides more robust protection for the via 121, further reducing the risk of the first electrode 1311 in the via 121 being exposed.

[0082] Similarly, such as Figure 2As shown, in some embodiments, optionally, the orthographic projections of at least two of the first via 121A, the second via 121B, and the third via 121C on the substrate 110 lie within the orthographic projection of the same notch 142 on the substrate 110. By disposing at least two of the first via 121A, the second via 121B, and the third via 121C below the notch 142 between two adjacent sub-isolation structures 141 in the same isolation structure 140, a protective layer 150 can be provided at the notch 142 location to centrally protect the vias 121. Optionally, the first via 121A, the second via 121B, and the third via 121C are disposed below the notch 142 between two adjacent sub-isolation structures 141 in the same isolation structure 140.

[0083] The light-emitting material in the light-emitting unit 131 emits light under the action of an electric field. In some embodiments, the light-emitting unit 131 may optionally include a second electrode 1312 and a light-emitting functional part 1313. The second electrode 1312 and the first electrode 1311 are opposite to each other and spaced apart. The light-emitting functional part 1313 is disposed between the first electrode 1311 and the second electrode 1312. The protective layer 150 includes the second electrode 1312 and the light-emitting functional part 1313.

[0084] One of the first electrode 1311 and the second electrode 1312 can be an anode, and the other of the first electrode 1311 and the second electrode 1312 can be a cathode. In this way, an electric field will be generated between the first electrode 1311 and the second electrode 1312, which are arranged opposite to each other and spaced apart. The light-emitting functional unit 1313 can emit light under the action of this electric field. The light-emitting functional unit 1313 can include a multi-layer structure. For example, the light-emitting functional unit 1313 includes a hole injection unit, a hole transport unit, a light-emitting unit, an electron transport unit, an electron injection unit, etc., which are stacked. By making the protective layer 150 include the second electrode 1312 and the light-emitting functional unit 1313, the fabrication of the protective layer 150 does not require additional processes. It can be fabricated together with the second electrode 1312 and the light-emitting functional unit 1313 in the light-emitting unit 131, which can reduce the difficulty of the manufacturing process and reduce the manufacturing cost.

[0085] To further avoid signal crosstalk between adjacent light-emitting units 131, in some embodiments, the display panel 100 may optionally include a pixel defining layer 160. The pixel defining layer 160 is disposed on the side of the insulating layer 120 away from the substrate 110, and defines a plurality of pixel openings 161 spaced apart from each other. The light-emitting units 131 are at least partially located within the pixel openings 161. An isolation structure 140 is disposed on the side of the pixel defining layer 160 away from the substrate 110. By providing the pixel defining layer 160 and the pixel openings 161 defined by the pixel defining layer 160, the light-emitting units 131 are at least partially disposed within the pixel openings 161, and the isolation structure 140 is disposed on the pixel defining layer 160, which facilitates the shaping and configuration of the light-emitting units 131 and the isolation structure 140.

[0086] In order to encapsulate and protect the display panel 100 as a whole, in some embodiments, the display panel 100 may optionally include an encapsulation layer 151, which is disposed on the side of the light-emitting layer 130 away from the substrate 110, and the protective layer 150 includes the encapsulation layer 151.

[0087] The encapsulation layer 151 can be a single-layer structure made of inorganic or organic materials, or a multilayer structure made of at least one of inorganic or organic materials. It can encapsulate and protect other structures in the display panel 100. By including the encapsulation layer 151 in the protective layer 150, the protective layer 150 can be manufactured together with the encapsulation layer 151 without additional steps. The encapsulation layer 151 not only encapsulates and protects the entire display panel 100, but also protects the first electrode 1311 in the via 121. In this embodiment, the encapsulation layer 151 is an inorganic encapsulation layer. Optionally, an organic encapsulation layer, another inorganic encapsulation layer, a touch layer, an organic adhesive layer, a cover plate, etc., can also be provided on the side of the encapsulation layer 151 away from the substrate 110. The specific configuration can be determined according to actual conditions and is not limited here.

[0088] The specific structural form of the isolation structure 140 is not limited. In some embodiments, in the direction perpendicular to the surface of the substrate 110, the isolation structure 140 includes an isolation body 1411 and a blocking portion 1412. The blocking portion 1412 is located on the side of the isolation body 1411 away from the substrate 110, and the orthogonal projection of the isolation body 1411 on the substrate 110 is located within the orthogonal projection of the blocking portion 1412 on the substrate 110. The encapsulation layer 151 at least covers the sidewall of the isolation body 1411 and at least a portion of the surface of the blocking portion 1412 on the side away from the isolation body 1411.

[0089] In other words, the isolation structure 140 includes a relatively independent isolator 1411 and a blocking portion 1412. The isolator 1411 is located on the substrate 110 or the pixel defining layer 160, and the blocking portion 1412 is located on the side of the isolator 1411 facing away from the substrate 110. The area covered by the orthogonal projection of the blocking portion 1412 on the substrate 110 is larger, while the area covered by the orthogonal projection of the isolator 1411 on the substrate 110 is relatively smaller, so that the orthogonal projection of the blocking portion 1412 on the substrate 110 can cover the orthogonal projection of the isolator 1411 on the substrate 110. The cross-sectional shapes of the isolator 1411 and the blocking portion 1412 can include regular shapes, such as rectangles or triangles, or irregular shapes. Figure 2 In the illustrated embodiment, the cross-sectional shape of the isolator 1411 includes an inverted trapezoid, and the cross-sectional shape of the blocking portion 1412 includes a rectangle. By employing the isolation structure 140 designed above, and having the encapsulation layer 151 cover the sidewall of the isolator 1411 and at least a portion of the surface of the blocking portion 1412 on the side away from the isolator 1411, moisture can be effectively blocked, providing good protection for the first electrode 1311 in the via 121 of the display panel 100. It is understood that the isolation structure 140 includes a relatively independent base located on the side of the isolator 1411 away from the blocking portion 1412, and the orthographic projection of the isolator 1411 on the substrate 110 lies within the orthographic projection of the base on the substrate 110. Optionally, the base, the isolator 1411, and the blocking portion 1412 are made of different materials.

[0090] exist Figure 2 and Figure 3 In the embodiment shown, the protective layer 150 may also include a second electrode 1312, a light-emitting functional part 1313, and an encapsulation layer 151 stacked sequentially.

[0091] In some embodiments, optionally, the fabrication order of the first light-emitting unit 131A, the second light-emitting unit 131B, and the third light-emitting unit 131C may be the third light-emitting unit 131C, the second light-emitting unit 131B, and the first light-emitting unit 131A, respectively. When the protective layer 150 includes a second electrode 1312, a light-emitting functional part 1313, and an encapsulation layer 151 stacked sequentially, it may be the second electrode 1312, the light-emitting functional part 1313, and the encapsulation layer 151 corresponding to the third light-emitting unit 131C, or it may be the second electrode 1312, the light-emitting functional part 1313, and the encapsulation layer 151 corresponding to the second light-emitting unit 131B. Optionally, the colors of the first light-emitting unit 131A, the second light-emitting unit 131B, and the third light-emitting unit 131C may be red, green, and blue, respectively.

[0092] Please see Figure 4In some embodiments, the protective layer 150 may optionally include an optical adhesive layer 152. Using an optical adhesive layer 152 as the protective layer 150 provides better protection and lower cost. The optical adhesive layer 152 can be disposed in the gap 142 between two adjacent sub-isolation structures 141 and completely fill the gap 142. The optical adhesive layer 152 can also be disposed on the side of the blocking portion 1412 of the isolation structure 140 facing away from the substrate 110, thereby enhancing the protection effect on the via 121.

[0093] In some embodiments, optionally, the orthogonal projections of the first via 121A and the second via 121B on the substrate 110 are located within the orthogonal projection of the notch 142 on the substrate 110, and the protective layer 150 corresponding to the first via 121A and the second via 121B includes a second electrode 1312, a light-emitting functional part 1313 and an encapsulation layer 151 stacked sequentially; the orthogonal projection of the third via 121C on the substrate 110 is located within the orthogonal projection of the isolation structure 140 on the substrate 110, and the protective layer 150 corresponding to the third via 121C includes an optical adhesive layer 152.

[0094] In some embodiments, the optical adhesive layer 152 is located on the side of the isolation structure 140 away from the substrate 110, and / or, the optical adhesive layer 152 is located within at least one notch 142.

[0095] See Figures 5 to 8 As shown in the figure, this application embodiment also provides a display panel 200, which includes: a substrate 210, an insulating layer 220, a light-emitting layer 230, an isolation layer 240, and a protective layer 250. An insulating layer 220 and a light-emitting layer 230 are sequentially stacked on one side of a substrate 210. The light-emitting layer 230 includes a plurality of light-emitting units 231 spaced apart from each other. An isolation layer 240 is disposed on the side of the insulating layer 220 away from the substrate 210 and defines a plurality of first openings 241. The light-emitting units 231 are at least partially located within the first openings 241. The light-emitting units 231 include a first electrode 2311. The insulating layer 220 includes a via 221. The first electrode 2311 is at least partially inserted through the via 221. At least a portion of the orthographic projection of the via 221 on the substrate 210 is located within the orthographic projection of the isolation layer 240 on the substrate 210. A protective layer 250 is disposed on the side of the insulating layer 220 away from the substrate 210. The orthographic projection of the via 221 on the substrate 210 is located within the orthographic projection of the protective layer 250 on the substrate 210.

[0096] and Figures 2 to 4Unlike other embodiments, the display panel 200 in this embodiment includes an isolation layer 240 that covers the entire surface. The isolation layer 240 defines a plurality of first openings 241 and second openings 242. At least a portion of the light-emitting unit 231 is located within the first opening 241, that is, adjacent light-emitting units 231 are separated by the isolation layer 240. In this case, at least a portion of the via 221's orthogonal projection on the substrate 210 lies within the orthogonal projection of the isolation layer 240 on the substrate 210.

[0097] It is understood that the first electrode 2311 in this application may include a connection structure located in the via 221 of the insulating layer 220.

[0098] The display panel 200 of this application embodiment has at least a portion of the orthographic projection of the via 221 on the substrate 210 located within the orthographic projection of the isolation layer 240 on the substrate 210, and the orthographic projection of the via 221 on the substrate 210 located within the orthographic projection of the protective layer 250 on the substrate 210. That is, the via 221 is placed under the protective layer 250 and the isolation layer 240, so that the protective layer 250 and the isolation layer 240 can jointly protect the via 221. During the manufacturing process of the display panel 200, under the joint protection of the protective layer 250 and the isolation layer 240, the first electrode 2311 in the via 221 will not be exposed due to over-etching, and the light-emitting unit 231 will not be damaged during the manufacturing process, thus avoiding the problem of dark spots in the light-emitting unit 231 and improving the display effect of the display panel 200.

[0099] like Figure 5 As shown, in some embodiments, optionally, the light-emitting unit 231 includes a first light-emitting unit 231A, a second light-emitting unit 231B, and a third light-emitting unit 231C, and the via 221 includes a first via 221A, a second via 221B, and a third via 221C. At least a first electrode 2311 in the first light-emitting unit 231A passes through the first via 221A, at least a first electrode 2311 in the second light-emitting unit 231B passes through the second via 221B, and at least a first electrode 2311 in the third light-emitting unit 231C passes through the third via 221C. The orthographic projections of at least two of the first via 221A, the second via 221B, and the third via 221C onto the substrate 210 are located within the orthographic projection of the same second opening 242 onto the substrate 210. For example, Figure 5 The orthographic projections of the first via 221A and the second via 221B on the substrate 210 are both located within the orthographic projection of the same second opening 242 on the substrate 210.

[0100] In some embodiments, the first light-emitting unit 231A and the second light-emitting unit 231B are arranged alternately along the first direction X, and the first light-emitting unit 231A and the third light-emitting unit 231C are arranged alternately along the second direction Y.

Figure 5 In the illustrated embodiment, the light-emitting area of ​​the third light-emitting unit 231C includes a recessed portion 2314 recessed into the light-emitting area along a direction parallel to the surface of the substrate 210. The orthographic projection of the third via 221C on the substrate 210 overlaps with the orthographic projection of the recessed portion 2314 on the substrate 210. Thus, the recessed portion 2314 within the light-emitting area of ​​the third light-emitting unit 231C can partially accommodate the third via 221C and the first electrode 2311 in the third light-emitting unit 231C, resulting in high space utilization and improved arrangement density of the light-emitting units 231.

[0104] In some embodiments, optionally, the second opening 242 and the first opening 241 are spaced apart from each other, and at least a portion of the orthographic projection of the via 221 on the substrate 210 lies within the orthographic projection of the second opening 242 on the substrate 210.

[0105] In some embodiments, optionally, the second opening 242 is located between two first openings 241 that are opposite to each other and spaced apart. For example, Figure 5 The second opening 242 is located between the first opening 241 corresponding to the first light-emitting unit 231A and the first opening 241 corresponding to the second light-emitting unit 231B.

[0106] and Figures 2 to 4Similarly, in some embodiments, the light-emitting unit 231 may optionally include a second electrode 2312 and a light-emitting functional part 2313. The second electrode 2312 and the first electrode 2311 are opposite to each other and spaced apart. The light-emitting functional part 2313 is disposed between the first electrode 2311 and the second electrode 2312. The second electrode 2312 and the light-emitting functional part 2313 are at least partially located within the first opening 241. The protective layer 250 includes the second electrode 2312 and the light-emitting functional part 2313.

[0107] In some embodiments, the display panel 200 may optionally include a pixel defining layer 260, which is disposed on the side of the insulating layer 220 away from the substrate 210. The pixel defining layer 260 defines a plurality of pixel openings 261 spaced apart from each other, and the light-emitting unit 231 is at least partially located within the pixel openings 261. An isolation layer 240 is disposed on the side of the pixel defining layer 260 away from the substrate 210, and the orthographic projection of the pixel openings 261 on the substrate 210 is located within the orthographic projection of the first opening 241 on the substrate 210.

[0110] In some embodiments, the protective layer 250 may optionally include an optical adhesive layer 252.

[0111] In some embodiments, the optical adhesive layer 252 is optionally located on the side of the isolation layer 240 away from the substrate 210, and / or the isolation layer 240 further defines a plurality of second openings 242 in which the optical adhesive layer 252 is located.
