[0053] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0054] Please refer to Figure 1 , Figure 1 It is a top view of a display panel. The display panel 000 may have a display area 001 and a non-display area 002, and the non-display area 002 is located outside the display area 001. In order to meet product requirements, an opening area 003 may be provided in the display panel 000 for placing functional components with other functions, such as a camera. In this case, the display panel 000 may also have a transition area 004. Among them, the display area 001 is located outside the opening area 003, and the transition area 004 is located between the display area 001 and the opening area 003.

[0055] Please refer to Figure 2 and Figure 3 , Figure 2 yes Figure 1 A schematic cross-sectional view at AA' in FIG. Figure 3 yes Figure 1 A schematic cross-sectional view at BB' in FIG. 000 may include a substrate 100 , and a light emitting device 200 and an isolation column 300 located on one side of the substrate.

[0056] There may be more than one light emitting device 200 in the display panel 000, and the plurality of light emitting devices 200 may be distributed in the display area 001. Exemplarily, the display panel 000 may include: a first electrode layer 201, a light emitting layer 202, and a second electrode layer 203 that are stacked, and the first electrode layer 201, the light emitting layer 202, and the second electrode layer 203 are at least distributed in the display area 001. Here, the first electrode layer 201, the light emitting layer 202, and the second electrode layer 203 may be used to form a plurality of light emitting devices 200.

[0057] For example, the display panel 000 may further include: a pixel definition layer 400. The pixel definition layer 400 may be distributed in the display area 001, and the pixel definition layer 400 may have a plurality of pixel openings K, and a plurality of light-emitting devices 200 may correspond to the plurality of pixel openings K. For example, in one possible case, the plurality of light-emitting devices 200 may correspond to the plurality of pixel openings K one by one. The first electrode layer 201 may be located on the side of the pixel definition layer 400 facing the substrate 100, the light-emitting layer 202 may be located on the side of the pixel definition layer 400 facing away from the substrate 100, and the second electrode layer 203 may be located on the side of the light-emitting layer 202 facing away from the substrate 100. The first electrode layer 201 may include a plurality of first electrode blocks 201a corresponding to the plurality of pixel openings K one by one, and the orthographic projection of each first electrode block 201a on the substrate 100 may overlap with the orthographic projection of the corresponding pixel opening K on the substrate 100. The light-emitting layer 202 may include a plurality of light-emitting blocks 202a corresponding to a plurality of pixel openings K one by one, and the orthographic projection of each light-emitting block 202a on the substrate 100 may be located within the orthographic projection of the corresponding pixel opening K on the substrate 100. The second electrode layer 203 may include a plurality of second electrode blocks 203a corresponding to a plurality of pixel openings K one by one, and the orthographic projection of each second electrode block 203a on the substrate 100 may be located within the orthographic projection of the corresponding pixel opening K on the substrate 100. To this end, the light-emitting block 202a may be in contact with the corresponding first electrode block 201a. In this case, for any pixel opening K, the first electrode block 201a (also usually referred to as an anode) corresponding to the pixel opening K and stacked, the light-emitting block 202a, and the second electrode block 203a (also usually referred to as a cathode) may constitute a light-emitting device 200. It should be noted that a plurality of light-emitting devices 200 may share a cathode, and therefore, the second electrode layer 203 may further include a connecting portion 230b located between adjacently distributed second electrode blocks 203a.

[0058] The isolation column 300 in the display panel 000 may be located in the transition area 004, and the isolation column 300 may be distributed around the opening area 003. The isolation column 300 has a groove U on at least one of the side facing the display area 001 and the side facing the opening area 003. That is, in one possible case, the isolation column 300 has a groove U only on the side facing the display area 001; in another possible case, the isolation column 300 has a groove U only on the side facing the opening area 003; in another possible case, the isolation column 300 has a groove U on both the side facing the display area 001 and the side facing the opening area 003. For the convenience of description, the embodiment of the present application will be described in detail by taking the example that the isolation column 300 has a groove U on both the side facing the display area 001 and the side facing the opening area 003 as an example.

[0059] For example, Figure 2As shown, the isolation column 300 may include a first metal structure 301, a second metal structure 302 and a third metal structure 303 which are stacked, wherein the first metal structure 301 is closer to the substrate 100 than the third metal structure 303, the orthographic projection of the second metal structure 302 on the substrate 100 is located within the orthographic projection of the third metal structure 303 on the substrate 100, and the boundary of the orthographic projection of the second metal structure 302 on the substrate 100 does not overlap with the boundary of the orthographic projection of the third metal structure 303 on the substrate 100, and the orthographic projection of the third metal structure 303 on the substrate 100 overlaps with the orthographic projection of the first metal structure 301 on the substrate 100.

[0060] Since the isolation column 300 has a groove U, the isolation column 300 can be used to isolate the portion of the light-emitting layer 202 distributed in the transition area 004. That is, the portion of the light-emitting layer 202 distributed on the side of the isolation column 300 away from the substrate 100 can be disconnected from other portions. For example, the portion of the light-emitting layer 202 located in the transition area 004 may include: a first portion of the light-emitting layer 202 distributed on the side of the isolation column 300 away from the substrate 100, and a second portion isolated from the first portion. Therefore, the isolation column 300 can effectively prevent water and oxygen in the external environment from entering the display area 001 along the light-emitting layer 202 from the opening area 003, avoid water and oxygen from corroding the light-emitting device 200 in the display area 001, and ensure the display effect of the display panel 000. In a possible implementation, the isolation column 300 can be a ring body distributed around the opening area 003, so that the portion of the light-emitting layer 202 located in the transition area 004 can be more fully isolated by the isolation column 300. In this case, even if water and oxygen in the external environment invade into the light-emitting layer 202 in the transition zone 004 through the opening area 003, the invasion of water and oxygen can be blocked by the light-emitting layer 202 isolated in the transition zone 004 to ensure that water and oxygen in the external environment will not invade the portion of the light-emitting layer 202 located in the display area 001, thereby ensuring that the life of each light-emitting device 200 is relatively long.

[0061] In this application, please refer to Figure 3 The display panel 000 may further include: a plurality of pixel driving circuits P. The plurality of pixel driving circuits may be located on a side of the plurality of light emitting devices 200 facing the substrate 100, and may be electrically connected to the plurality of light emitting devices 200 in a one-to-one correspondence, and each pixel driving circuit P may be used to drive the corresponding light emitting device 200 to emit light. The pixel driving circuit P electrically connected to the light emitting device 200 in the display panel 000 may include: at least two transistors and at least one storage capacitor.

[0062] The storage capacitor may include: a first capacitor electrode C1 and a second capacitor electrode C2 arranged opposite to each other. The transistor may include: an active layer Act, a gate G, a source electrode S and a drain electrode D. The active layer Act may be insulated from the gate G, and the source electrode S and the drain electrode D may be overlapped with the active layer Act. The source electrode S may be electrically connected to a plurality of data lines distributed in the display area 001. In a possible case, as Figure 3 As shown, the drain electrode D may be electrically connected to the anode electrode 201a of the light emitting device 200. In another possible case, as Figure 4 As shown, Figure 4 yes Figure 1 In another cross-sectional view at BB', the drain electrode D can also be electrically connected to the anode 201a of the light emitting device 200 through the switching electrode Z. It should be noted that the switching electrode Z of the display panel 000 can be a single-layer structure or a multi-layer structure, and the present application does not impose any limitation on this.

[0063] like Figure 3 As shown, when the drain D is directly electrically connected to the anode 201a of the light-emitting device 200, the isolation column 300 can be arranged in the same layer as the source S and drain D layers in the display area 001 and the same material; or, when the display panel 000 has a switching electrode Z, the isolation column 300 can be arranged in the same layer as the source S and drain D layers in the display area 001, and at least one layer of the switching electrode Z layer and the same material.

[0064] For example, the isolation column 300 can be a titanium-aluminum-titanium three-layer structure, that is, the first metal structure 301 and the third metal structure 303 in the isolation column 300 are both metal titanium, and the second metal structure 302 is metal aluminum, wherein the thickness of the first metal structure 301 and the third metal structure 303 can range from 30 nanometers to 80 nanometers; the thickness of the second metal structure 302 can range from 400 nanometers to 800 nanometers. After the display panel 000 has prepared the titanium-aluminum-titanium three-layer structure of the pixel driving circuit P in the display area 001 and the isolation column 300 in the transition area 004, it is necessary to continue to form the first electrode layer 201, the pixel definition layer 400, the light-emitting layer 202, and the second electrode layer 203 and other film layers in sequence.

[0065] In the process of forming the first electrode layer 201, when an etching solution is used to perform the etching process, the etching solution will undergo a chemical replacement reaction with the isolation column 300. Since the activity of metal aluminum is greater than that of metal titanium, the etching speed of the etching solution on the second metal structure 302 is greater than the etching speed on the first metal structure 301 and the third metal structure 303, thereby forming a groove U on at least one side of the isolation column 300 facing the display area 001 and the side of the isolation column 300 facing the opening area 003.

[0066] To this end, in the subsequent process of forming the pixel definition layer 400 on the side of the first electrode layer 201 away from the substrate 100, for example, the pixel definition layer 400 can be an organic material, and the organic material has good fluidity. Therefore, when forming the pixel definition base layer, the organic material will enter the groove U of the isolation column 300.

[0067] Since the orthographic projection of the second metal structure 302 on the substrate 100 is located within the orthographic projection of the third metal structure 303 on the substrate 100, and the boundary of the orthographic projection of the second metal structure 302 on the substrate 100 does not overlap with the boundary of the orthographic projection of the third metal structure 303 on the substrate 100. That is, the side of the third metal structure 303 in the isolation column 300 facing the display area 001 protrudes out of the side of the second metal structure 302 facing the display area 001, and / or, the side of the third metal structure 303 facing the opening area 003 protrudes out of the side of the second metal structure 302 facing the opening area 003, the groove U of the isolation column 300 is blocked by the third metal structure 303, and the exposure light cannot enter the groove U, resulting in that the organic material in the groove U cannot be exposed. Therefore, organic residues 401 are easily formed in the groove U of the isolation column 300. The organic residues 401 can respectively contact the first part of the light-emitting layer 202 located on the side of the isolation column 300 away from the substrate 100 and the second part of the light-emitting layer 202 separated from the first part, forming a water and oxygen intrusion channel, causing water and oxygen in the external environment to easily invade the display area 001 from the opening area 003 through the water and oxygen intrusion channel formed by connecting the first part of the light-emitting layer 202, the organic residues 401 and the second part of the light-emitting layer 202, resulting in poor effect of isolating water and oxygen by the isolation column 300, which will further damage the light-emitting device 200 in the display area 001 and affect the display effect of the display panel 000.

[0068] To do this, refer to Figure 5 , Figure 5 The display panel 000 may further include: an auxiliary support portion 500 and a reflective portion 600 located on one side of the substrate 100 .

[0069] The auxiliary support part 500 in the display panel 000 is located in the transition area 004 and is distributed around the opening area 003. The side of the isolation column 300 having the groove U is arranged adjacent to the auxiliary support part 500, and the angle between the side of the auxiliary support part 500 facing the isolation column 300 and the side of the auxiliary support part 500 facing the substrate 100 is an acute angle.

[0070] The reflective portion 600 in the display panel 000 is at least distributed on the side surface of the auxiliary support portion 500 facing the spacer 300 .

[0071] In this case, please refer to Figure 6, Figure 6 This is a schematic diagram of an exposure light path of a display panel provided in an embodiment of the present application during the process of forming a pixel definition layer. The reflective portion 600 can reflect the exposure light into the groove U of the isolation column 300, so that the organic material in the groove U can be fully exposed, thereby removing the organic material in the groove U and avoiding the formation of organic residues in the groove U of the isolation column 300, thereby ensuring the isolation effect of the isolation column 300 on the light-emitting layer 202, avoiding the invasion of water and oxygen in the external environment from the opening area 003 into the display area 001, and ensuring the display effect of the display panel 000.

[0072] It should be noted that, since the angle between the side of the auxiliary support part 500 facing the isolation column 300 and the side of the auxiliary support part 500 facing the substrate 100 is an acute angle, it can be ensured that the reflective part 600 arranged on the side of the auxiliary support part 500 facing the isolation column 300 is also arranged obliquely relative to the substrate 100. In this way, the reflective part 600 can better reflect the exposure light into the groove U of the isolation column 300, so as to ensure that the organic material in the groove U can be more fully exposed.

[0073] In a possible implementation, the auxiliary support portion 500 may also be a ring body distributed around the opening area 003. In this way, it can be ensured that the reflecting portion 600 distributed on the auxiliary support portion 500 is also a ring body distributed around the opening area 003, and further ensured that the reflecting portion 600 can reflect the exposure light into the groove U of the annular isolation column 300, so as to ensure that the organic materials in the groove U can be more fully exposed.

[0074] In summary, the display panel provided by the present application includes: a substrate, and a light-emitting device, an isolation column, an auxiliary support portion and a reflective portion located on one side of the substrate. Since the auxiliary support portion is arranged adjacent to the side of the isolation column having a groove, and the angle between the side of the auxiliary support portion facing the isolation column and the side of the auxiliary support portion facing the substrate is an acute angle, the reflective portion is at least distributed on the side of the auxiliary support portion facing the isolation column. Therefore, the reflective portion can reflect the exposure light into the groove of the isolation column, so that the organic material in the groove can be fully exposed, thereby removing the organic material in the groove, avoiding the formation of organic residues in the groove of the isolation column, thereby ensuring the isolation effect of the isolation column on the light-emitting layer, avoiding the water and oxygen in the external environment from invading the display area from the opening area, and ensuring the display effect of the display panel.

[0075] It should be noted that if Figure 5As shown, in the direction perpendicular to the substrate 100, the distance d1 between the side of the auxiliary support portion 500 facing away from the substrate 100 and the side of the isolation column 300 facing the substrate 100 is less than the height d2 of the isolation column 300. The height d2 of the isolation column 300 refers to: the distance between the side of the isolation column 300 facing away from the substrate 100 and the side of the isolation column 300 facing the substrate 100. In this case, the reflective portion 600 distributed on the side of the auxiliary support portion 500 facing the isolation column 300 can reflect the exposure light into the groove U of the isolation column 300, so that the organic material in the groove U can be fully exposed, thereby removing the organic material in the groove U, avoiding the formation of organic residues in the groove U of the isolation column 300, thereby ensuring the isolation effect of the isolation column 300 on the light-emitting layer 202, preventing water and oxygen in the external environment from invading from the opening area 003 into the display area 001, and ensuring the display effect of the display panel 000.

[0076] In the examples of this application, please refer to Figure 7 , Figure 7 is a cross-sectional schematic diagram of another display panel at the transition zone provided by an embodiment of the present application. The reflective portion 600 may also be distributed on the side of the auxiliary support portion 500 facing away from the substrate 100, and / or, on the side of the auxiliary support portion 500 facing away from the isolation column 300. Exemplarily, the reflective portion 600 may be distributed simultaneously on the side of the auxiliary support portion 500 facing the isolation column 300, the side of the auxiliary support portion 500 facing away from the substrate 100, and the side of the auxiliary support portion 500 facing away from the isolation column 300. That is, the orthographic projection of the auxiliary support portion 500 on the substrate 100 may be located within the orthographic projection of the reflective portion 600 on the substrate 100. In this case, it can be ensured that the process of forming the reflective portion 600 on the auxiliary support portion 500 is relatively simple, thereby simplifying the difficulty of preparing the display panel.

[0077] It should be noted that there are many possible implementations of the auxiliary support portion 500 , and the embodiments of the present application are schematically described using the following two possible implementations as examples.

[0078] For the first possible implementation, please refer to Figure 7 The auxiliary support portion 500 may include: a first sub-support portion 501 and a second sub-support portion 502 which are stacked.

[0079] The first sub-support portion 501 is closer to the substrate 100 than the second sub-support portion 502, and the orthographic projection of the first sub-support portion 501 on the substrate 100 is located within the orthographic projection of the second sub-support portion 502 on the substrate 100. For example, the second sub-support portion 502 can cover the side of the first sub-support column 501 facing the opening area 003, the side of the first sub-support column 501 facing away from the substrate 100, and the side of the first sub-support column 501 facing away from the opening area 003.

[0080] In the present application, the angle between the first side surface 501a of the first sub-support portion 501 facing the isolation column 300 and the side of the first sub-support portion 501 facing the substrate 100 is an acute angle. In this case, the reflective portion 600 is at least distributed on the portion of the second sub-support portion 502 covering the first side surface 501a, so that the reflective portion 600 distributed on the portion of the second sub-support portion 502 covering the first side surface 501a can be tilted relative to the substrate 100.

[0081] In a possible case, the angle between the second side surface 501b of the first sub-support portion 501 facing away from the isolation column 300 and the side of the first sub-support portion 501 facing the substrate 100 is also an acute angle. In this way, the reflective portion 600 distributed on the portion of the second sub-support portion 502 covering the second side surface 501b can be arranged obliquely relative to the substrate 100, so that it can better reflect the exposure light into the groove U of the adjacent isolation column 300.

[0082] In the present application, the display panel 000 may further include: an inorganic insulating layer 700 located on one side of the substrate 100. The first sub-support portion 501 is located on the side of the inorganic insulating layer 700 facing the substrate 100, and the portion of the inorganic insulating layer 700 covering the first sub-support portion 501 is the second sub-support portion 502. The isolation column 300 is located on the side of the inorganic insulating layer 700 facing away from the substrate 100, and the isolation column 300 is in contact with the inorganic insulating layer 700.

[0083] Here, since the thickness of the inorganic insulating layer 700 at various positions is approximately the same, when the inorganic insulating layer 700 covers the first sub-support portion 501, the portion of the inorganic insulating layer 700 covering the first sub-support portion 501 will bulge upward according to the morphology of the first sub-support portion 501, so that the portion of the inorganic insulating layer 700 covering the first sub-support portion 501 can serve as the second sub-support portion 502. And when the angle between the first side surface 501a of the first sub-support portion 501 facing the isolation column 300 and the side of the first sub-support portion 501 facing the substrate 100 is an acute angle, it can be ensured that the portion of the second sub-support portion 502 covering the first side surface 501a is tilted relative to the substrate 100, and further, it can be ensured that the reflective portion 600 formed on the portion of the second sub-support portion 502 covering the first side surface 501a is also tilted relative to the substrate 100.

[0084] Optionally, the display panel 000 may further include: a conductive pattern layer located on the side of the inorganic insulating layer 700 facing the substrate 100 . The portion of the conductive pattern layer located in the transition region 004 may include a first sub-support portion 501 .

[0085] It should be noted that the conductive pattern layer can also be distributed in other areas of the display panel 000. For example, the conductive pattern layer can be distributed in the display area 001 of the display panel 000, and the portion distributed in the display area 001 can be used as a conductive portion in the pixel driving circuit P. In addition, the inorganic insulating layer 700 can also be distributed in the display area 001 and used as an insulating layer for insulating two adjacent conductive portions in the pixel driving circuit P. In this way, in the process of forming the pixel driving circuit P, the first sub-support portion 501 and the second sub-support portion 502 can be formed simultaneously, thereby effectively simplifying the preparation process of the display panel 000.

[0086] For example, Figure 3 As shown, the display panel 000 may also include: a first gate insulating layer 900 located between the active layer Act and the gate G, a first conductive layer 801 where the gate G and the first capacitor electrode C1 are located, a second gate insulating layer 701 located between the first capacitor electrode C1 and the second capacitor electrode C2, a second conductive layer 802 where the second capacitor electrode C2 is located, and an interlayer dielectric layer 702 located between the second conductive layer 802 and the source S and drain D layers. Here, the first conductive layer 801 and / or the second conductive layer 802 may be used as a conductive pattern layer, and the second gate insulating layer 701 and / or the interlayer dielectric layer 702 may be used as an inorganic insulating layer 700. To this end, the inorganic insulating layer 700 and the conductive pattern layer 800 may have a variety of possible implementations.

[0087] In a possible case, the conductive pattern layer can be the first conductive layer 801, that is, the first sub-support portion 501 can be arranged in the same layer as the gate G and the first capacitor electrode C1 and made of the same material. The portion of the conductive pattern layer located in the display area 001 can include: the gate G and the first capacitor electrode C1 in the pixel driving circuit P, and the portion of the conductive pattern layer 800 located in the transition area 004 can include: the first sub-support portion 501 in the auxiliary support portion 500. In this case, the inorganic insulating layer 700 can be at least one of the second gate insulating layer 701 and the interlayer dielectric layer 702. For example, the portion of the second gate insulating layer 701 covering the first sub-support portion 501 is the second sub-support portion 502; or, the portion of the interlayer dielectric layer 702 covering the first sub-support portion 501 is the second sub-support portion 502; or, the first portion of the second gate insulating layer 701 covering the first sub-support portion 501 and the second portion of the interlayer dielectric layer 702 covering the first portion together constitute the second sub-support portion 502.

[0088] In another possible case, the conductive pattern layer 800 may be the second conductive layer 802, that is, the first sub-support portion 501 may be arranged in the same layer as the second capacitor electrode C2 and made of the same material. The portion of the conductive pattern layer located in the display area 001 may include: the second capacitor electrode C2 in the pixel driving circuit P, and the portion of the conductive pattern layer located in the transition area 004 may include: the first sub-support portion 501 in the auxiliary support portion 500. In this case, the inorganic insulating layer 700 may be an interlayer dielectric layer 702. That is, the portion of the interlayer dielectric layer 702 covering the first sub-support portion 501 is the second sub-support portion 502.

[0089] In another possible case, please refer to Figure 8 , Figure 8 It is a cross-sectional schematic diagram of another display panel at the transition zone provided by an embodiment of the present application. The conductive pattern layer can be a first conductive layer 801 and a second conductive layer 802, that is, the first sub-support portion 501 can include: a first portion 5011 arranged in the same layer as the gate G and the first capacitor electrode C1 and made of the same material, and a second portion 5012 arranged in the same layer as the second capacitor electrode C2 and made of the same material. In this case, the inorganic insulating layer 700 can be a second gate insulating layer 701 and an interlayer dielectric layer 702. That is, the second sub-support portion 502 can include: a third portion 5021 of the second gate insulating layer 701 covering the first portion 5011 of the first sub-support portion 501, and a fourth portion 5022 of the interlayer dielectric layer 702 covering the second portion 5012 of the first sub-support portion 501.

[0090] For the second possible implementation, please refer to Fig. 9 , Fig. 9is a schematic cross-sectional view of another display panel at the transition region provided by an embodiment of the present application, and the auxiliary support portion 500 may be formed of an organic material. Figure 3 As shown, the display panel may further include: an organic planar layer 1000 located in the display area 001 , and the organic planar layer 1000 is located on a side of the light emitting device 200 facing the substrate 100 .

[0091] In one possible scenario, Figure 3 As shown, the drain electrode D may be electrically connected to the anode of the light emitting device 200, and the organic planar layer 1000 may be located on the side of the source electrode S and the drain electrode D layer away from the substrate 100. The organic planar layer 1000 may ensure that the portion of the display panel 000 located in the display area 001 has good planarity, so as to ensure that the subsequent formation of multiple light emitting devices 200 on the side of the organic planar layer 1000 away from the substrate 100 has good effect.

[0092] In this case, the auxiliary support part 500 may be disposed at the same layer as the organic planarization layer 1000 and may be made of the same material.

[0093] In another possible situation, Figure 4 As shown, the drain electrode D can also be electrically connected to the anode of the light-emitting device 200 through a layer of transition electrode Z, and the organic flat layer 1000 may include: a first organic flat layer 1001 and a second organic flat layer 1002. The first organic flat layer 1001 may be located on the side of the source electrode S and the drain electrode D layer away from the substrate 100; the second organic flat layer 1002 may be located on the side of the transition electrode Z layer away from the substrate 100. The first organic flat layer 1001 can ensure that the portion of the display panel 000 located in the display area 001 has good flatness, so as to ensure that the effect of subsequently forming the transition electrode Z on the side of the first organic flat layer 1001 away from the substrate 100 is good, and the second organic flat layer 1002 can ensure that the portion of the display panel 000 located in the display area 001 has good flatness, so as to ensure that the effect of subsequently forming multiple light-emitting devices 200 on the side of the second organic flat layer 1002 away from the substrate 100 is good. Furthermore, the second organic planarization layer 1002 can also protect the transfer electrode Z layer from being over-etched when etching the first electrode layer 201 , thereby ensuring the integrity of the transfer electrode Z and the yield of the pixel driving circuit P.

[0094] In this case, the auxiliary support part 500 may be disposed in the same layer as at least one of the first organic planarization layer 1001 and the second organic planarization layer 1002 and may be made of the same material.

[0095] In the examples of this application, please refer to Fig.10 , Fig.10: is a cross-sectional schematic diagram of another display panel at the transition zone provided by an embodiment of the present application. Since the side of the isolation column 300 having the groove U is arranged adjacent to the auxiliary support portion 500, therefore, in the case where the side of the isolation column 300 facing away from the opening area 003 and the side of the isolation column 300 facing the opening area 003 both have the groove U, the display panel 000 may include: at least one isolation column 300 and at least two auxiliary support portions 500, one isolation column 300 corresponds to two auxiliary support portions 500, and the two auxiliary support portions 500 corresponding to one isolation column 300 are respectively a first auxiliary support portion 510 and a second auxiliary support portion 520. Among them, for one isolation column 300, the first auxiliary support portion 510 is distributed on the side of the isolation column 300 facing the opening area 003, and the second auxiliary support portion 520 is distributed on the side of the isolation column 300 facing away from the opening area 003.

[0096] It should be noted that in order to ensure that the exposure light reflected by the reflective portion 600 can fully expose the organic residues in the groove U of the isolation column 300, the minimum distance d3 between the isolation column 300 and the corresponding first auxiliary support portion 510 is in the range of 2 microns to 4 microns, and the minimum distance d4 between the isolation column 300 and the corresponding second auxiliary support portion 520 is in the range of 2 microns to 4 microns.

[0097] It should also be noted that, when the display panel 000 includes multiple isolation columns 300, for two adjacent isolation columns 300, the second auxiliary support portion corresponding to the isolation column closer to the opening area 003 and the first auxiliary support portion corresponding to the isolation column further away from the opening area 003 can be the same auxiliary support portion.

[0098] For example, Fig.10 As shown, two adjacent isolation columns in the display panel 000 are respectively: a first isolation column 310 and a second isolation column 320. Among them, the first isolation column 310 is closer to the opening area 003 than the second isolation column 320. The first auxiliary support portion 510 corresponding to the first isolation column 310 is distributed on the side of the first isolation column 310 facing the opening area 003, and the second auxiliary support portion 520 corresponding to the first isolation column 310 is distributed on the side of the first isolation column 310 away from the opening area 003. The first auxiliary support portion 510 corresponding to the second isolation column 320 is distributed on the side of the second isolation column 320 facing the opening area 003, and the second auxiliary support portion 520 corresponding to the second isolation column 320 is distributed on the side of the second isolation column 320 away from the opening area 003. The second auxiliary support portion 520 corresponding to the first isolation column 310 and the first auxiliary support portion 510 corresponding to the second isolation column 320 can be the same auxiliary support portion.

[0099] In the embodiment of the present application, the reflective portion 600 can be disposed in the same layer and made of the same material as the plurality of first electrode blocks 201a in the display area 001. That is, the portion of the first electrode layer 201 of the display panel 000 located in the display area 001 can include: a plurality of separately disposed first electrode blocks 201a, and the portion of the first electrode layer 201 located in the transition area 004 includes: the reflective portion 600. In this way, the manufacturing process of the display panel 000 can be effectively simplified.

[0100] It should be noted that the reflective portion 600 may adopt a three-layer reflective structure of indium tin oxide-silver-indium tin oxide. During the exposure stage of the patterning process, the reflectivity of the reflective portion 600 to the exposure light ranges from 80% to 90%.

[0101] Please refer to Fig.11 , Fig.11 004 is a schematic cross-sectional view of another display panel in the transition region provided in an embodiment of the present application. The display panel 000 may further include: at least one organic barrier dam 1100. The present application embodiment takes the display panel 000 including an organic barrier dam 1100 as an example for schematic illustration. The organic barrier dam 1100 is located in the transition region 004 and is distributed around the opening region 003. Figure 3 As shown, the display panel 000 may further include an encapsulation layer 1200, which is located on the side of the light-emitting device 200 away from the substrate 100. The encapsulation layer 1200 may include: a first inorganic encapsulation layer 1201, an organic encapsulation layer 1202, and a second inorganic encapsulation layer 1203 that are stacked. Here, the first inorganic encapsulation layer 1201 may be in contact with the side of the second electrode layer 203 away from the substrate 100, that is, the first inorganic encapsulation layer 1201 may cover a plurality of light-emitting devices 200. The organic encapsulation layer 1202 may ensure that the portion of the display panel 000 located in the display area 001 has good flatness, so as to ensure that other functional layers (for example, a touch electrode layer) formed on the portion of the encapsulation layer 1200 located in the display area 001 subsequently have good effects. However, since the organic encapsulation layer 1202 has strong fluidity and poor water and oxygen isolation capabilities, an organic barrier dam 1100 is required to prevent the organic encapsulation layer 1202 from entering the opening area 003, and a second inorganic encapsulation layer 1203 is used to cover the side of the organic encapsulation layer 1202 facing away from the substrate 100, and the edge portion of the first inorganic encapsulation layer 1201 close to the opening area 003 needs to be in contact with the edge portion of the second inorganic encapsulation layer 1203 close to the opening area 003 to ensure that the first inorganic encapsulation layer 1201 and the second inorganic encapsulation layer 1203 can wrap the organic encapsulation layer 1202.

[0102] To this end, the organic encapsulation layer 1202 may be located outside the area enclosed by the organic barrier dam 1100, and the orthographic projections of the first inorganic encapsulation layer 1201 and the second inorganic encapsulation layer 1203 on the substrate 100 cover the orthographic projections of the organic barrier dam 1100 on the substrate 100. That is, there is a partial boundary between the orthographic projections of the first inorganic encapsulation layer 1201 and the second inorganic encapsulation layer 1203 on the substrate 100, which may be located between the orthographic projections of the organic barrier dam 1100 on the substrate 100 and the orthographic projections of the opening area 003 on the substrate 100.

[0103] It should be noted that if Fig.11 As shown, the organic barrier dam 1100 may include: a first sub-dam 1101 and a second sub-dam 1102 arranged in a stacked manner. The first sub-dam 1101 is closer to the substrate 100 than the second sub-dam 1102. The first sub-dam 1101 may be arranged in the same layer and made of the same material as the organic planar layer 1000 in the display area 001, and the second sub-dam 1102 may be arranged in the same layer and made of the same material as the pixel definition layer 400 in the display area 001. It should also be noted that, in the case where the display panel 000 includes the first organic planar layer 1001 and the second organic planar layer 1002, the first sub-dam 1101 may be arranged in the same layer and made of the same material as at least one of the first organic planar layer 1001 and the second organic planar layer 1002.

[0104] It should also be noted that the display panel 000 may include a plurality of isolation columns 300, and the plurality of isolation columns 300 are all located in the transition region 004 and are distributed around the opening region 003. The organic barrier dam 1100 may be located between two adjacent isolation columns 300. For example, Fig.11 As shown, the organic barrier dam 1100 may be located between the adjacently distributed third spacer column 330 and the fourth spacer column 340, and the third spacer column 330 is closer to the opening area 003 than the fourth spacer column 340. In this case, in order to ensure that the groove U1 of the third spacer column 330 facing away from the opening area 003 and the groove U2 of the fourth spacer column 340 facing the opening area 003 can be fully exposed by the reflective portion 600, thereby avoiding the formation of organic residues in the above two grooves U1 and U2, which affects the isolation effect of the third spacer column 330 and the fourth spacer column 340 on the light-emitting layer 202, the second auxiliary support portion 520 corresponding to the third spacer column 330 and the first auxiliary support portion 510 corresponding to the fourth spacer column 340 are not the same auxiliary support portion, and the organic barrier dam 1100 is located between the second auxiliary support portion 520 corresponding to the third spacer column 330 and the first auxiliary support portion 510 corresponding to the fourth spacer column 340.

[0105] like Figure 3 and Figure 4As shown, the display panel 000 may further include: a buffer layer 1300 located on one side of the substrate 100 . The buffer layer 1300 is located on the side of the active layer Act facing the substrate 100 , and can avoid damage to the substrate 100 when etching the active layer Act.

[0106] The display panel 000 may further include: a passivation layer 1400 located on the side of the organic planar layer 1000 facing the substrate 100 , the passivation layer 1000 may protect the source S and drain D layers from being over-etched when etching other film layers, thereby ensuring the integrity of the source S and drain D and ensuring the yield of the pixel driving circuit P.

[0107] In summary, the display panel provided by the present application includes: a substrate, and a light-emitting device, an isolation column, an auxiliary support portion and a reflective portion located on one side of the substrate. Since the auxiliary support portion is arranged adjacent to the side of the isolation column having a groove, and the angle between the side of the auxiliary support portion facing the isolation column and the side of the auxiliary support portion facing the substrate is an acute angle, the reflective portion is at least distributed on the side of the auxiliary support portion facing the isolation column. Therefore, the reflective portion can reflect the exposure light into the groove of the isolation column, so that the organic material in the groove can be fully exposed, thereby removing the organic material in the groove, avoiding the formation of organic residues in the groove of the isolation column, thereby ensuring the isolation effect of the isolation column on the light-emitting layer, avoiding the water and oxygen in the external environment from invading the display area from the opening area, and ensuring the display effect of the display panel.

[0108] The present application also provides a display device, which includes: a power supply component, and a display panel 000 electrically connected to the power supply component. The display panel 000 may include any of the display panels 000 given above. The display device can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, an advertising machine, a display screen, a digital photo frame, etc.

It is also understood that when an element or layer is referred to as being "on" another element or layer, it may be directly on the other element, or there may be an intermediate layer.
