[0001] This application relates to the field of displays, specifically to a display panel, a display device, and a method for manufacturing the display panel. Background Technology

[0002] With the rapid development of display technology, the demand for large-size display panels (especially top-emitting display panels) is increasing. Currently, top-emitting display panels utilize reflective anodes and semi-reflective, semi-transparent cathodes to form microcavities. The interaction between the microcavity structure and the light-emitting material enhances the microcavity efficiency, thereby significantly improving the luminous efficiency of the light-emitting pixels. However, the light emitted from the light-emitting layer in existing display panels is relatively concentrated, resulting in a narrow viewing angle and affecting the display quality. Summary of the Invention

The reflective layer has multiple reflective surfaces on the side away from the array substrate, and two adjacent reflective surfaces are intersecting.

[0007] The light-emitting layer is disposed on the side of the first electrode layer opposite to the array substrate.

[0008] Optionally, in some embodiments of this application, the anode layer further includes a second electrode layer located between the reflective layer and the array substrate.

[0009] Optionally, in some embodiments of this application, the second electrode layer has a first opening on the side facing away from the array substrate, and the reflective layer is partially located in the first opening, so that the side of the reflective layer facing away from the array substrate forms a recessed area corresponding to the position of the first opening.

[0013] Optionally, in some embodiments of this application, the angle formed between the sidewall of the second opening and the side of the reflective surface facing the array substrate is greater than or equal to 5 degrees and less than or equal to 80 degrees.

[0014] Accordingly, this application also provides a display device, which includes the display panel described in any of the above claims.

[0015] Accordingly, this application also provides a method for manufacturing a display panel, the method comprising:

[0016] Provide an array substrate;

[0017] A reflective layer is deposited on the array substrate, and multiple reflective surfaces are formed on the side of the reflective layer facing away from the array substrate; two adjacent reflective surfaces are arranged intersectingly.

[0018] A first electrode layer is deposited on the side of the reflective layer opposite to the array substrate;

[0019] A light-emitting layer is formed on the side of the first electrode layer that is away from the array substrate.

[0020] Optionally, in some embodiments of this application, depositing a reflective layer on the array substrate includes:

[0021] A second electrode layer is deposited on the array substrate;

[0022] The second electrode layer is etched to form a first opening on the side of the second electrode layer opposite to the array substrate;

[0023] A reflective layer is deposited on the side of the second electrode layer away from the array substrate, such that a portion of the reflective layer is located within the first opening, thereby forming a recessed region on the side of the reflective layer away from the array substrate corresponding to the first opening.

The light-emitting layer is disposed on the side of the first electrode layer facing away from the array substrate. By forming multiple reflective surfaces on the side of the reflective layer facing away from the array substrate, and with adjacent reflective surfaces intersecting, this application ensures that when light emitted from the light-emitting layer passes through the first electrode layer and illuminates the reflective layer, it is reflected at different angles after being reflected by the multiple reflective surfaces of the reflective layer. This helps to increase the light-emitting angle of the light-emitting layer and improve the overall viewing angle of the display panel. Attached Figure Description

[0041] Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0043] This application provides a display panel, a display device, and a method for manufacturing the display panel, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0044] First, this application provides a display panel, such as... Figures 1 to 4 As shown, the display panel 100 includes an array substrate 110, in which a thin-film transistor layer is disposed. The thin-film transistor layer serves as a switching function layer of the display panel 100, used to control the display mode of the display panel 100.

[0045] The material type of the thin-film transistor in the thin-film transistor layer can be low-temperature poly-silicon (LTPS) thin-film transistor, oxide thin-film transistor, or solid-phase crystallization (SPC) thin-film transistor, etc., and its structure type can be any type such as top-gate structure, bottom-gate structure, or dual-gate structure, without any special limitation here.

[0046] The display panel 100 includes an anode layer 130 disposed on an array substrate 110. The anode layer 130 includes a reflective layer 132 and a first electrode layer 131 disposed sequentially along a direction away from the array substrate 110. The first electrode layer 131 is a transparent electrode, which allows light emitted from inside the display panel 100 to pass through the first electrode layer 131 to the reflective layer 132 and be reflected out by the reflective layer 132, thereby improving the light emission rate of the display panel 100. At the same time, the reflective layer 132 can also reflect light from the external environment, preventing light from the external environment from directly shining into the display panel 100 and affecting the display effect of the display panel 100.

[0047] The reflective layer 132 has multiple reflective surfaces 1321 on the side facing away from the array substrate 110, and two adjacent reflective surfaces 1321 are arranged intersectingly. That is, the side of the reflective layer 132 facing away from the array substrate 110 is not a flat plane, but is formed by multiple planes connected to each other at an angle, thereby forming multiple reflective surfaces 1321. This structural design allows light emitted from inside the display panel 100 to shine on the reflective layer 132, and after being reflected by the multiple reflective surfaces 1321 of the reflective layer 132, it can be reflected at different reflection angles, thereby helping to increase the overall light-emitting viewing angle of the display panel 100 and improve the display effect of the display panel 100.

[0048] The display panel 100 includes a light-emitting layer 150, which is disposed on the side of the first electrode layer 131 facing away from the array substrate 110. By inputting a control signal onto the first electrode layer 131, the light-emitting layer 150 can be controlled to emit light. Before forming the light-emitting layer 150, a pixel definition layer 140 is formed, and pixel openings are created on the pixel definition layer 140, exposing a portion of the anode layer 130. The light-emitting layer 150 is then disposed within the pixel openings to define the position of the light-emitting pixels. Part of the light emitted from the light-emitting layer 150 passes through the first electrode layer 131 to the reflective layer 132. After being reflected by multiple reflective surfaces 1321 of the reflective layer 132, it is reflected out at different angles, thereby increasing the emission angle of the light-emitting layer 150.

[0049] The light-emitting layer 150 can be formed on the first electrode layer 131 by vapor deposition or inkjet printing. Since the side of the reflective layer 132 facing away from the array substrate 110 is composed of multiple intersecting reflective surfaces 1321, the side of the first electrode layer 131 facing away from the reflective layer 132 after deposition on the reflective layer 132 is not a flat plane. In this case, forming the light-emitting layer 150 by vapor deposition helps to ensure the uniformity of the thickness of the light-emitting layer 150, thereby improving the display effect of the display panel 100.

[0050] In this embodiment, the display panel 100 includes an array substrate 110, an anode layer 130, and a light-emitting layer 150. The anode layer 130 is disposed on the array substrate 110 and includes a reflective layer 132 and a first electrode layer 131 sequentially disposed along a direction away from the array substrate 110. The reflective layer 132 has multiple reflective surfaces 1321 on the side away from the array substrate 110, with adjacent reflective surfaces 1321 intersecting. The light-emitting layer 150 is disposed on the side of the first electrode layer 131 away from the array substrate 110. By forming multiple reflective surfaces 1321 on the side of the reflective layer 132 away from the array substrate 110, and with adjacent reflective surfaces 1321 intersecting, the light emitted by the light-emitting layer 150 passes through the first electrode layer 131 to the reflective layer 132 and is reflected by the multiple reflective surfaces 1321 of the reflective layer 132, resulting in different reflection angles. This helps to increase the light emission angle of the light-emitting layer 150 and improve the overall viewing angle of the display panel 100.

[0051] Optional, such as Figures 1 to 3 As shown, the anode layer 130 also includes a second electrode layer 133, which is located between the reflective layer 132 and the array substrate 110. That is, the anode layer 130 is composed of the second electrode layer 133, the reflective layer 132, and the first electrode layer 131 stacked together. Before forming the anode layer 130 on the array substrate 110, a planarization layer 120 needs to be formed on the array substrate 110 to planarize the surface of the array substrate 110, so as to facilitate the subsequent film layer fabrication.

[0052] The planarization layer 120 is an organic layer containing substances such as moisture. If the reflective layer 132 is directly placed on the planarization layer, the moisture and other substances in the planarization layer may erode the reflective layer 132 and affect the structural stability of the anode layer 130. Therefore, by setting a second electrode layer 133 between the reflective layer 132 and the planarization layer 120, it is helpful to ensure the structural stability of the reflective layer 132, thereby helping to ensure the overall display effect of the display panel 100.

[0053] Optionally, the second electrode layer 133 has a first opening 1331 on the side away from the array substrate 110, and the reflective layer 132 is partially located in the first opening 1331, so that the side of the reflective layer 132 away from the array substrate 110 forms a recessed area 1322 corresponding to the position of the first opening 1331, thereby forming a plurality of reflective surfaces 1321.

[0054] In other words, when forming the second electrode layer 133, a first opening 1331 is formed on the side of the second electrode layer 133 away from the array substrate 110, so that the side of the second electrode layer 133 away from the array substrate 110 is composed of multiple intersecting surfaces. Then, a reflective layer 132 and a first electrode layer 131 are uniformly deposited sequentially on the second electrode layer 133, so that the side of the reflective layer 132 away from the array substrate 110 forms multiple intersecting reflective surfaces 1321. The reflective surface 1321 can be consistent with the surface structure of the side of the second electrode layer 133 away from the array substrate 110.

[0055] Since the reflective layer 132 is made of metal, its internal resistance is relatively small compared to the first electrode layer 131 and the second electrode layer 133. This structural design helps to ensure the uniformity of the thickness of the reflective layer 132, thereby helping to reduce the overall internal resistance of the anode layer 130 and thus helping to improve the display effect of the display panel 100.

[0056] In some embodiments, such as Figure 1 As shown, the first opening 1331 extends along the thickness direction of the second electrode layer 133 and penetrates the second electrode layer 133. That is, the second electrode layer 133 is not a continuous film layer after patterning. This structural design makes the area of ​​the reflective surface 1321 formed by the reflective layer 132 at an angle to the initial horizontal plane larger under the same thickness. This allows more light emitted by the light-emitting layer 150 to be reflected by the reflective surface 1321, which is different from the horizontal plane. This helps to further increase the overall light emission angle of the light-emitting layer 150, thereby improving the light emission viewing angle of the display panel 100.

[0057] In other embodiments, such as Figure 2 and Figure 3 As shown, the depth of the first opening 1331 is less than the thickness of the second electrode layer 133. This means that the second electrode layer 133 remains a continuous film after patterning. This structural design reduces the step difference between the reflective layer 132 and the first electrode layer 131 while maintaining the same thickness, thus improving the thickness uniformity of the subsequent light-emitting layer 150 and consequently improving the display effect of the display panel 100. Furthermore, this structural design also reduces the erosion of the reflective layer 132 by moisture, ensuring the structural stability of the reflective layer 132 and further contributing to the overall display effect of the display panel 100.

[0058] The specific depth of the first opening 1331 can be adjusted according to the actual design and usage. No special restrictions are imposed here. It is only necessary to ensure that the setting of the first opening 1331 can enable the reflective layer 132 to form multiple reflective surfaces 1321 on the side away from the array substrate 110, thereby increasing the light emission angle of the light emission layer 150 and improving the light emission viewing angle of the display panel 100.

[0059] Optionally, the angle between the sidewall of the first opening 1331 and the side of the second electrode layer 133 facing the array substrate 110 is greater than or equal to 5 degrees and less than or equal to 80 degrees. Since the structure of the reflective surface 1321 of the reflective layer 132 and the surface of the second electrode layer 133 facing away from the array substrate 110 can be kept consistent, when the structure of the reflective surface 1321 of the reflective layer 132 and the surface of the second electrode layer 133 facing away from the array substrate 110 is kept consistent, the angle between the reflective surface 1321 on the reflective layer 132 corresponding to the sidewall position of the first opening 1331 and the reflective surface 1321 on the reflective layer 132 located in the horizontal position is greater than or equal to 5 degrees and less than or equal to 80 degrees.

[0060] If the included angle is too small, the angle difference between the reflective surface 1321 on the reflective layer 132 corresponding to the sidewall of the first opening 1331 and the reflective surface 1321 on the reflective layer 132 in a horizontal position will be too small. The angle difference after the light-emitting layer 150 shines on the corresponding reflective surface 1321 will be small, thus failing to effectively increase the light-emitting angle of the light-emitting layer 150. If the included angle is too large, the reflective surface 1321 on the reflective layer 132 corresponding to the sidewall of the first opening 1331 and the reflective surface 1321 on the reflective layer 132 in a horizontal position will tend to be perpendicular. This will make it difficult for the light emitted by the light-emitting layer 150 to shine on the reflective surface 1321 on the reflective layer 132 corresponding to the sidewall of the first opening 1331, and similarly, it will fail to effectively increase the light-emitting angle of the light-emitting layer 150.

[0061] In the actual manufacturing process, the angle formed between the sidewall of the first opening 1331 and the side of the second electrode layer 133 facing the array substrate 110 can be set to 5 degrees, 10 degrees, 20 degrees, 50 degrees or 80 degrees, etc. The specific value can be adjusted according to the actual design and usage requirements. It is only necessary to ensure that the setting of the first opening 1331 can effectively increase the light emission angle of the light emission layer 150 and improve the overall light emission viewing angle of the display panel 100. No special limitation is made here.

[0062] It should be noted that the angle formed by the sidewall of the first opening 1331 and the side of the second electrode layer 133 facing the array substrate 110 refers to the angle formed by the sidewall of the first opening 1331 and the side of the second electrode layer 133 facing the array substrate 110. The angle formed by the two sides includes an obtuse angle and an acute angle. In the embodiments of this application, the acute angle is used to represent the angle.

[0063] Optional, such as Figure 4 As shown, a second opening 1323 is provided on the side of the reflective layer 132 away from the array substrate 110, and the depth of the second opening 1323 is less than the thickness of the reflective layer 132. The inner wall of the second opening 1323 forms part of the reflective surface 1321 in the reflective layer 132. That is, when forming the reflective layer 132, the reflective layer 132 can be directly patterned to form the second opening 1323 on the reflective layer 132, thereby forming multiple reflective surfaces 1321. At the same time, the continuity of the reflective layer 132 is ensured, so that the reflective layer 132 is set as a whole surface. This structural design allows the multiple reflective surfaces 1321 of the reflective layer 132 to be obtained by adjusting the structure of the reflective layer 132 itself, making the setting of multiple reflective surfaces 1321 more flexible and convenient.

[0064] Specifically, the angle formed between the sidewall of the second opening 1323 and the side of the reflective layer 132 facing the array substrate 110 is greater than or equal to 5 degrees and less than or equal to 80 degrees. If the angle is too small, the angle difference between the reflective surface 1321 corresponding to the sidewall of the second opening 1323 and the horizontally positioned reflective surface 1321 on the reflective layer 132 will be too small, resulting in a small angle difference after reflection when the light-emitting layer 150 is irradiated onto the corresponding reflective surface 1321, thus failing to effectively increase the light-emitting angle of the light-emitting layer 150. If the angle is too large, the reflective surface 1321 corresponding to the sidewall of the second opening 1323 and the horizontally positioned reflective surface 1321 on the reflective layer 132 will tend to be perpendicular, which is not conducive to the light emitted by the light-emitting layer 150 irradiating onto the reflective surface 1321 corresponding to the sidewall of the second opening 1323 on the reflective layer 132, and similarly, it will not effectively increase the light-emitting angle of the light-emitting layer 150.

[0065] In the actual manufacturing process, the angle formed between the sidewall of the second opening 1323 and the side of the reflective layer 132 facing the array substrate 110 can be set to 5 degrees, 10 degrees, 20 degrees, 50 degrees or 80 degrees, etc. The specific value can be adjusted according to the actual design and usage requirements. It is only necessary to ensure that the setting of the second opening 1323 can effectively increase the light emission angle of the light emission layer 150 and improve the overall light emission viewing angle of the display panel 100. No special limitation is made here.

[0066] In some embodiments, a first opening 1331 is formed on the second electrode layer 133, and a second opening 1323 is formed on the reflective layer 132. The first opening 1331 and the second opening 1323 are staggered in the thickness direction of the array substrate 110. This structural design can avoid the openings on the second electrode layer 133 or the reflective layer 132 being too dense, which would make the manufacturing process more difficult. At the same time, it can also increase the number of reflective surfaces 1321, further increase the light emission angle of the light-emitting layer 150, and improve the overall light emission viewing angle of the display panel 100.

[0067] Optionally, in the embodiments of this application, the cross-sectional shape of the first opening 1331 and the second opening 1323 in the thickness direction of the array substrate 110 can be one or more of quadrilaterals, triangles, semicircles or other polygons. The specific shape can be adjusted according to actual usage requirements and manufacturing process, and no special restrictions are imposed here.

[0068] It should be noted that when the cross-sectional shape of the first opening 1331 and the second opening 1323 in the thickness direction of the array substrate 110 is an arc, that is, when the sidewalls of the first opening 1331 and the second opening 1323 are curved surfaces, the angle between the sidewalls of the first opening 1331 and the second opening 1323 and the corresponding horizontal plane refers to the angle between the tangent plane corresponding to any point on the sidewall of the first opening 1331 and the second opening 1323 and the horizontal plane.

[0069] Optionally, in this embodiment, the first electrode layer 131 and the second electrode layer 133 are made of the same material, including transparent materials such as indium tin oxide. This allows light emitted from the light-emitting layer 150 to pass through the first electrode layer 131 and illuminate the reflective layer 132, which then reflects the light away, thereby improving the light extraction efficiency and viewing angle of the display panel 100. The reflective layer 132 is made of a metal material with high reflectivity and low resistance, such as silver or aluminum. This ensures effective reflection of the light emitted from the light-emitting layer 150 and reduces the overall internal resistance of the anode layer 130, thus helping to improve the display effect of the display panel 100.

[0070] Secondly, this application embodiment also provides a display device, which includes a display panel. The specific structure of the display panel is as described in the above embodiments. Since this display device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0071] like Figure 5As shown, the display device 10 includes a display panel 100, a control circuit 200, and a housing 300. The housing 300 is connected to the display panel 100 to support and fix the display panel 100. The control circuit 200 is disposed inside the housing 300 and is electrically connected to the display panel 100 to control the display panel 100 to display images.

[0072] The display panel 100 can be fixed to the housing 300, forming an integral whole. The display panel 100 and the housing 300 form a sealed space to house the control circuit 200. The control circuit 200 can be the mainboard of the display device 10. Furthermore, the control circuit 200 can integrate one or more functional components such as a battery, antenna structure, microphone, speaker, headphone jack, universal serial bus interface, camera, proximity sensor, ambient light sensor, and processor, enabling the display device 10 to adapt to various application fields.

[0073] It should be noted that the display device 10 is not limited to the above-mentioned components. It may also include other components, such as a camera, an antenna structure, a fingerprint unlocking module, etc., to expand its application scope. No restrictions are imposed here.

[0074] The display device 10 in this application embodiment has a wide range of applications, including flexible displays such as televisions, computers, mobile phones, foldable and rollable displays, and lighting, as well as wearable devices such as smart bracelets and smartwatches, all of which fall within the application field of the display device 10 in this application embodiment.

[0075] Finally, this application also provides a method for manufacturing a display panel, which can be used to manufacture the display panel described in the above embodiments. Figure 6 As shown, the manufacturing method of the display panel mainly includes the following steps:

[0076] S100, Provide an array substrate 110.

[0077] When fabricating the display panel 100, an array substrate 110 is first formed. A thin-film transistor (TFT) layer is disposed in the array substrate 110. The TFT layer serves as the switching function layer of the display panel 100, used to control the display mode of the display panel 100. The TFTs in the TFT layer can be made of low-temperature poly-silicon (LTPS), oxide, or solid-phase crystallization (SPC) thin-film transistors, and their structural type can be any type, such as top-gate, bottom-gate, or dual-gate; no special limitation is made here.

[0078] S200, a reflective layer 132 is deposited on the array substrate 110, and multiple reflective surfaces 1321 are formed on the side of the reflective layer 132 away from the array substrate 110; two adjacent reflective surfaces 1321 are arranged to intersect.

[0079] After the array substrate 110 is fabricated, a reflective layer 132 is deposited on the array substrate 110, so that multiple reflective surfaces 1321 are formed on the side of the reflective layer 132 away from the array substrate 110, and two adjacent reflective surfaces 1321 are arranged to intersect. That is, the side of the reflective layer 132 away from the array substrate 110 is not a flat plane, but is formed by multiple planes connected to each other at an angle, thereby forming multiple reflective surfaces 1321.

[0080] This structural design allows light emitted from inside the display panel 100 to be reflected at different angles after being reflected by multiple reflective surfaces 1321 of the reflective layer 132. This helps to increase the overall viewing angle of the display panel 100 and improve its display effect. Simultaneously, the reflective layer 132 also reflects light from the external environment, preventing direct light from entering the display panel 100 and affecting its display performance.

[0081] Optionally, in some embodiments, step S200 involves depositing a reflective layer 132 on the array substrate 110, forming multiple reflective surfaces 1321 on the side of the reflective layer 132 facing away from the array substrate 110. This mainly includes the following:

[0082] like Figure 7 As shown, a second electrode layer 133 is deposited on the array substrate 110, and then the second electrode layer 133 is etched to form a first opening 1331 on the side of the second electrode layer 133 away from the array substrate 110; then a reflective layer 132 is deposited on the side of the second electrode layer 133 away from the array substrate 110, such that part of the reflective layer 132 is located in the first opening 1331, so that a recessed region 1322 is formed on the side of the reflective layer 132 away from the array substrate 110 corresponding to the position of the first opening 1331, thereby forming a plurality of reflective surfaces 1321.

[0083] The second electrode layer 133 is located between the reflective layer 132 and the array substrate 110. Before forming the anode layer 130 on the array substrate 110, a planarization layer 120 needs to be formed on the array substrate 110 to planarize the surface of the array substrate 110, so as to facilitate the subsequent film layer fabrication. Since the planarization layer 120 is an organic layer, it contains substances such as moisture. If the reflective layer 132 is directly placed on the planarization layer, the moisture and other substances in the planarization layer may erode the reflective layer 132 and affect the structural stability of the anode layer 130. Therefore, by setting the second electrode layer 133 between the reflective layer 132 and the planarization layer 120, it helps to ensure the structural stability of the reflective layer 132, thereby helping to ensure the overall display effect of the display panel 100.

[0084] When forming the second electrode layer 133, a first opening 1331 is formed on the side of the second electrode layer 133 away from the array substrate 110, so that the side of the second electrode layer 133 away from the array substrate 110 is composed of a plurality of intersecting surfaces. Then, a reflective layer 132 is uniformly deposited on the second electrode layer 133, so that a plurality of intersecting reflective surfaces 1321 are formed on the side of the reflective layer 132 away from the array substrate 110. The reflective surface 1321 can be consistent with the surface structure of the side of the second electrode layer 133 away from the array substrate 110.

[0085] Since the reflective layer 132 is made of metal, its internal resistance is relatively small compared to the second electrode layer 133. This structural design helps to ensure the uniformity of the thickness of the reflective layer 132, thereby helping to reduce the overall internal resistance of the anode layer 130 and thus helping to improve the display effect of the display panel 100.

[0086] The specific structure of the first opening 1331 can be described in accordance with the specific description of the structure of the display panel 100 in the above embodiments, and will not be repeated here.

[0087] Optionally, in other embodiments, step S200 involves depositing a reflective layer 132 on the array substrate 110, forming multiple reflective surfaces 1321 on the side of the reflective layer 132 facing away from the array substrate 110. This mainly includes the following:

[0088] like Figure 9 As shown, a reflective layer 132 is deposited on the array substrate 110, and then the reflective layer 132 is etched to form a second opening 1323 on the side of the reflective layer 132 away from the array substrate 110. The depth of the second opening 1323 is less than the thickness of the reflective layer 132, so that a plurality of reflective surfaces 1321 are formed on the side of the reflective layer 132 away from the array substrate 110.

[0089] That is, when forming the reflective layer 132, the reflective layer 132 can be directly patterned to form a second opening 1323 on the reflective layer 132, thereby forming multiple reflective surfaces 1321. At the same time, the continuity of the reflective layer 132 is ensured, so that the reflective layer 132 is set as a whole surface. This structural design allows the multiple reflective surfaces 1321 of the reflective layer 132 to be obtained through the structural adjustment of the reflective layer 132 itself, making the setting of multiple reflective surfaces 1321 more flexible and convenient.

[0090] The specific structure of the second opening 1323 and the combination of the second opening 1323 and the first opening 1331 can be referred to the relevant description of the structure of the display panel 100 in the above embodiments, and will not be repeated here.

[0091] S300, a first electrode layer 131 is deposited on the side of the reflective layer 132 facing away from the array substrate 110.

[0092] like Figure 8 and Figure 10 As shown, after the reflective layer 132 is fabricated, a first electrode layer 131 is uniformly deposited on the reflective layer 132, such that the surface shape of the first electrode layer 131 is consistent with the surface shape of the reflective layer 132. The first electrode layer 131 and the reflective layer 132 constitute the anode layer 130. The first electrode layer 131 is a transparent electrode, allowing light emitted from inside the display panel 100 to pass through the first electrode layer 131 and illuminate the reflective layer 132, and then be reflected out by the reflective layer 132, thereby improving the light extraction efficiency of the display panel 100.

[0093] S400, a light-emitting layer 150 is formed on the side of the first electrode layer 131 opposite to the array substrate 110.

[0094] After the anode layer 130 is fabricated, a light-emitting layer 150 is formed on the anode layer 130. By inputting a control signal on the first electrode layer 131, the light-emitting layer 150 can be controlled to emit light. Before forming the light-emitting layer 150, a pixel definition layer 140 needs to be coated first. Then, the pixel definition layer 140 is exposed and developed to form a pixel opening on the pixel definition layer 140, exposing part of the anode layer 130. The light-emitting layer 150 is then placed within the pixel opening to define the position of the light-emitting pixel.

[0095] The light-emitting layer 150 can be formed on the first electrode layer 131 by vapor deposition or inkjet printing. Since the side of the reflective layer 132 facing away from the array substrate 110 is composed of multiple intersecting reflective surfaces 1321, the side of the first electrode layer 131 facing away from the reflective layer 132 after deposition on the reflective layer 132 is not a flat plane. In this case, forming the light-emitting layer 150 by vapor deposition helps to ensure the uniformity of the thickness of the light-emitting layer 150, thereby improving the display effect of the display panel 100.

[0096] After the light-emitting layer 150 is fabricated, the method of fabricating the display panel 100 also includes forming a cathode layer 160 on the light-emitting layer 150. By inputting control signals on the anode layer 130 and the cathode layer 160, the display mode of the display panel 100 can be adjusted to meet the different display requirements of the display panel 100.

[0097] The above provides a detailed description of a display panel, display device, and method for manufacturing the display panel according to embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
