[0068] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0069] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating directions or positional relationships, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0070] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the embodiments of the present application. In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0071] like Figure 1 and Figure 2a As shown, a display panel provided by an embodiment of the first aspect of the present application includes: a substrate 100, an isolation structure 200, a light-emitting layer, a first flat layer 410 and a filter layer 500, wherein the isolation structure 200 is arranged on one side of the substrate 100, and the isolation structure 200 encloses an isolation opening 240; the light-emitting layer includes a light-emitting unit 300 arranged in the isolation opening 240; the first flat layer 410 is arranged on the side of the light-emitting layer away from the substrate 100; and the filter layer 500 is arranged on the side of the first flat layer 410 away from the substrate 100.

[0072] In this embodiment, the isolation structure 200 encloses and forms an isolation opening 240, and the light-emitting unit 300 is arranged in the isolation opening 240. The isolation structure 200 can reduce the light crosstalk between adjacent light-emitting units 300, thereby improving the display effect of the display panel. The first flat layer 410 is arranged on the side of the light-emitting layer away from the substrate 100 to flatten the step difference between the light-emitting layer and the isolation structure 200, so as to facilitate the manufacture of the filter layer 500. The filter layer 500 is arranged on the side of the first flat layer 410 away from the substrate 100, and the filter layer 500 can filter the emitted light of the light-emitting unit 300, thereby improving the display effect of the display panel.

[0073] In some embodiments, the side of the light-emitting layer facing away from the substrate 100 is flattened by inkjet printing of organic materials, and the thickness of the organic material in the middle portion is greater than the thickness at the edge, thereby generating a height step difference, which will affect the thickness of the filter layer 500 when the filter layer 500 is subsequently manufactured, making the thickness of the filter layer 500 uneven and thus affecting the light filtering effect. In the present application, the first flat layer 410 is used to flatten the side of the light-emitting layer facing away from the substrate 100, and the height step difference between the middle portion and the edge portion of the first flat layer 410 is small, so that the thickness uniformity of the filter layer 500 is better, thereby improving the performance of the display panel.

[0074] In addition, disposing the filter layer 500 on the first planar layer 410 can reduce the distance between the filter layer 500 and the light-emitting layer.

[0075] There are many ways to set the substrate 100. The substrate 100 may include a substrate and a first conductive layer, a second conductive layer, and a third conductive layer that are arranged on one side of the substrate and are stacked. An insulating layer is provided between adjacent conductive layers. Exemplarily, a pixel driving circuit is provided on the substrate 100, and the pixel driving circuit includes a transistor and a storage capacitor. The transistor includes a semiconductor, a gate, a source and a drain. The storage capacitor includes a first plate and a second plate. As an example, the gate and the first plate may be located in the first conductive layer, the second plate may be located in the second conductive layer, and the source and the drain may be located in the third conductive layer.

[0076] Optionally, the material of the first planar layer 410 may include optical glue, so that the first planar layer 410 has good fluidity and can better planarize the step difference between the light emitting layer and the isolation structure 200 .

[0077] like Figures 1 to 3 As shown, in some optional embodiments, the display panel has a display area AA and a retaining wall area 110 arranged around the display area AA, and the retaining wall area 110 is arranged on one side of the substrate 100; the first flat layer 410 is located in the area enclosed by the retaining wall area 110, the first flat layer 410 includes a first area 411 and a second area 412, the second area 412 is located between the first area 411 and the retaining wall area 110, and the first flat layer 410 includes a first surface 413 facing away from the side of the substrate 100, and the first surface 413 located in the second area 412 is arranged at an equal distance from the substrate 100.

[0078] In these optional embodiments, the second region 412 is arranged around the first region 411, the retaining wall area 110 is arranged around the side of the second region 412 away from the first region 411, in the second region 412, the first surface 413 of the first flat layer 410 is equidistant from the substrate 100, the side of the first flat layer 410 away from the substrate 100 is parallel to the plane where the substrate 100 is located, and the filter layer 500 is arranged on one side of the first surface 413.

[0079] The retaining wall area 110 includes a plurality of dams disposed on one side of the substrate 100, and the height of the dams from the plane where the substrate 100 is located is greater than or equal to the height of the first planar layer 410 from the plane where the substrate 100 is located. Each dam surrounds at least one side of the display area AA, and the plurality of dams are successively disposed along a plane parallel to the substrate 100.

[0080] In some embodiments, the thickness of the organic material in the second region 412 varies greatly on the side of the light-emitting layer away from the substrate 100 by self-leveling, that is, the thickness of the organic material is thinner as it approaches the retaining wall region 110, thereby affecting the thickness uniformity of the filter layer 500. In this embodiment, the first surface 413 of the first flat layer 410 in the second region 412 is arranged at an equal distance from the substrate 100, such as Figure 3 In the embodiment, the distance between the first surface 413 of the first flat layer 410 in the second region 412 and the substrate 100 is B, so that a flattened first surface 413 can be formed on the side of the first flat layer 410 in the second region 412 away from the substrate 100, thereby improving the thickness uniformity of the filter layer 500.

[0081] Optionally, the first surface 413 in the first region 411 and the first surface 413 in the second region 412 are at the same distance from the substrate 100, so that the first surface 413 in the first region 411 and the first surface 413 in the second region 412 can be in the same plane, thereby improving the thickness uniformity of the filter layer 500 in the first region 411 and the filter layer 500 in the second region 412. Figure 3 In the embodiment, the distance between the first surface 413 of the first planar layer 410 in the first region 411 and the substrate 100 is b, where B=b.

[0082] like Figure 2a As shown, in some optional embodiments, the first planar layer 410 covers the side of the light emitting unit 300 facing away from the substrate 100 and fills the isolation opening 240 .

[0083] In these optional embodiments, the first planarization layer 410 fills the isolation opening 240 and covers the side of the light emitting unit 300 facing away from the substrate 100 , thereby planarizing the side of the isolation structure 200 and the light emitting unit 300 facing away from the substrate 100 .

[0084] Optional, such as Figure 2a As shown, the first flat layer 410 also covers the side of the isolation structure 200 facing away from the substrate 100, and the distance D between the first surface 413 of the first flat layer 410 facing away from the substrate 100 and the substrate 100 is greater than the distance d between the side of the isolation structure 200 facing away from the substrate 100 and the substrate 100, that is, the first flat layer 410 covers the isolation opening 240 and the isolation structure 200, so that the filter layer 500 can be completely manufactured on the first surface 413, reducing the influence of the isolation structure 200 on the filter layer 500.

[0085] like Figure 2a As shown, in some optional embodiments, the display panel includes a first encapsulation layer, the first encapsulation layer includes an encapsulation portion 420 arranged on the side of the light-emitting unit 300 away from the substrate 100, the encapsulation portion 420 extends from the isolation opening 240 to the side of the isolation structure 200 away from the substrate 100, and the first flat layer 410 is arranged on the side of the encapsulation portion 420 away from the substrate 100.

[0086] In these optional embodiments, the packaging part 420 can package the light-emitting unit 300, reducing water, oxygen, etc. from entering the light-emitting unit 300 and affecting the service life of the light-emitting unit 300. The packaging part 420 extends from the isolation opening 240 to the side of the isolation structure 200 away from the substrate 100, thereby improving the packaging effect of the packaging part 420.

[0087] like Figure 2a As shown, in some optional embodiments, a sealed gap 421 is formed between two adjacent packaging parts 420 and is located on the side of the isolation structure 200 away from the substrate 100 , and a portion of the first flat layer 410 is located in the sealed gap 421 and is arranged in contact with the isolation structure 200 .

[0088] In these optional embodiments, each light-emitting unit 300 is provided with a packaging part 420 on the side facing away from the substrate 100, and two adjacent packaging parts 420 are arranged at intervals or partially in contact. Two adjacent packaging parts 420 have a sealing gap 421 on the side of the isolation structure 200 facing away from the substrate 100, ensuring that the light-emitting unit 300 on the side of the isolation structure 200 facing away from the substrate 100 is removed, and part of the first flat layer 410 is located in the sealing gap 421 and is arranged in contact with the isolation structure 200 to fill the sealing gap 421.

[0089] like Figure 2a As shown, in some optional embodiments, the isolation structure 200 includes a first sublayer 210 and a second sublayer 220, the first sublayer 210 is located on the side of the second sublayer 220 facing the substrate 100, and the orthographic projection of the first sublayer 210 on the substrate 100 is located within the orthographic projection of the second sublayer 220 on the substrate 100.
