The light shielding structure 300 includes a first light shielding portion 310 disposed on the side of the semiconductor structure 211 away from the substrate 110, and the orthographic projection of the semiconductor structure 211 on the substrate 110 overlaps with the orthographic projection of the first light shielding portion 310 on the substrate 110 at least partially, so that the first light shielding portion 310 can be used to limit the light from irradiating to the semiconductor structure 211, for example, the first light shielding portion 310 can be used to limit the infrared light from irradiating to the semiconductor structure 211, so that the semiconductor structure 211 can have better working stability.

[0144] Optionally, the material of the light shielding structure 300 may include a light shielding material. For example, the material of the light shielding structure 300 may include at least one of a reflective material and a light absorbing material. For example, the material of the light shielding structure 300 may include an opaque metal material.

[0145] Optionally, at least a portion of the light-shielding structure 300 may be arranged in the same layer and with the same material as at least a portion of the devices or film layer structures arranged in the substrate 100, so that in the preparation process of the display panel 10, the same preparation equipment can be used in the same preparation step to prepare at least a portion of the light-shielding structure 300 and at least a portion of the devices or film layer structures arranged in the substrate 100, which can greatly improve the preparation efficiency of the display panel 10.

[0146] The first light shielding portion 310 is provided with a first connecting opening 311, which penetrates the first light shielding portion 310 along the thickness direction X of the display panel 10. The first connecting opening 311 allows the device or structure between the first light shielding portion 310 and the substrate 110 to be led out to the side of the first light shielding portion 310 away from the substrate 110. The first electrode layer 500 is disposed on one side of the substrate 100 and includes a plurality of first electrodes 510 disposed at intervals. By arranging that the orthographic projection of at least one first connecting opening 311 on the substrate 110 is located within the orthographic projection of the first electrode 510 on the substrate 110, the first electrode 510 can be used to limit the light from irradiating to the first connecting opening 311, so that the light is not easy to irradiate to the semiconductor structure 211 through the first connecting opening 311, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.

[0149] In some embodiments of the present application, the display panel 10 provided in the embodiments of the present application may be an organic light emitting diode (OLED) display panel 10 .

[0150] In some optional embodiments, the display panel 10 may further include a light-emitting layer 600 and a second electrode layer 700 disposed on the side of the first electrode layer 500 facing away from the substrate 100. The light-emitting layer 600 may include a light-emitting unit 610 disposed on the side of the first electrode 510 facing away from the substrate 100, and the second electrode layer 700 may include a second electrode 710 disposed on the side of the light-emitting unit 610 facing away from the substrate 100.

[0151] Optionally, the light-emitting unit 610 may include a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting structure, an electron injection layer (EIL) and an electron transport layer (ETL).

[0152] Optionally, the display panel 10 may further include a pixel definition layer 800 disposed on the side of the first electrode layer 500 facing away from the substrate 100. The pixel definition layer 800 may include a pixel defining portion 810. The pixel defining portion 810 may be provided with a pixel opening 811. The light-emitting unit 610 may be at least partially located in the pixel opening 811. The pixel definition layer 800 may be used to participate in dividing the sub-pixels of the display panel 10.

[0153] Optionally, at least a portion of the first electrode 510 is exposed from the pixel opening 811 , so that a portion of the surface of the first electrode 510 facing away from the substrate 100 can be connected to the light-emitting unit 610 after being exposed from the pixel opening 811 .

[0154] In these optional embodiments, the first electrode 510 and the second electrode 710 can be used as pixel electrodes of the display panel 10, one of the first electrode 510 and the second electrode 710 can be used as an anode, and the other can be used as a cathode to drive the light-emitting unit 610 to emit light. The embodiment of the present application is described by taking the first electrode 510 as the anode of the display panel 10 and the second electrode 710 as the cathode of the display panel 10 as an example.

[0155] In some optional embodiments, the display panel 10 may have a display area AA and a non-display area NA, wherein the first electrode 510, the light-emitting unit 610 and the second electrode 710 may be at least partially disposed in the display area AA, so that the display panel 10 located in the display area AA can perform light-emitting display.

[0156] Optionally, the display panel 10 may have a first display area AA1 and a second display area AA2. For example, the display area AA may include the first display area AA1 and the second display area AA2. Both the first display area AA1 and the second display area AA2 can be used for luminous display, that is, the first display area AA1 and the second display area AA2 may be provided with a first electrode 510, a light-emitting unit 610 and a second electrode 710 for participating in the luminous display of the display panel 10.

[0157] Optionally, a semiconductor structure 211 may be disposed in both the first display area AA1 and the second display area AA2 to facilitate light emitting display control of each sub-pixel in the first display area AA1 and the second display area AA2.

[0158] Optionally, the first display area AA1 may at least partially surround the second display area AA2.

[0159] Optionally, the transmittance of the second display area AA2 may be greater than the transmittance of the first display area AA1, so that when the display panel 10 is applied to a display device, the photosensitive component for sensing light in the display device may be correspondingly arranged under the second display area AA2, so that the second display area AA2 is not likely to have a large shielding effect on the light, so that the photosensitive component can better sense the light. For example, the photosensitive component may include: at least one of: a face recognition sensor, a camera, an under-screen fingerprint recognition module, an infrared light emitting diode (IR-LED) proximity sensor, a distance sensor, and other components capable of sensing light.

[0160] Optionally, the number of second display areas AA2 may be one, which can facilitate the control of the sub-pixel display in the second display area AA2. For example, when the display panel 10 is applied to a display device, by setting the number of second display areas AA2 to one, it can facilitate the control chip in the display device to control the sub-pixel display in the second display area AA2.

[0161] Optionally, the sub-pixel arrangement density in the second display area AA2 may be less than the sub-pixel arrangement density in the first display area AA1, so as to achieve that the light transmittance of the second display area AA2 is greater than the light transmittance of the first display area AA1. For example, the arrangement density of the first electrodes 510 in the second display area AA2 may be less than the arrangement density of the first electrodes 510 in the first display area AA1. For example, the arrangement density of the light-emitting units 610 in the second display area AA2 may be less than the arrangement density of the light-emitting units 610 in the first display area AA1.

[0162] In some optional embodiments, the light shielding structure 300 may be disposed in the second display area AA2.

[0163] In this optional embodiment, since the light transmittance in the second display area AA2 is higher, the semiconductor structure 211 located in the second display area AA2 is more easily affected by light. Therefore, by setting the shading structure 300 in the second display area AA2, the shading structure 300 can better limit the light from irradiating to the semiconductor structure 211 located in the second display area AA2, thereby better improving the working stability of the semiconductor structure 211 in the second display area AA2.

[0164] Optionally, the shading structure 300 may not be disposed in the first display area AA1, which can reduce the space occupied by the shading structure 300 in the first display area AA1 and facilitate the arrangement of devices or film structures in the first display area AA1.

Exemplarily, the first electrode 510 may be electrically connected to the semiconductor structure 211 of some transistors 210 in the driving circuit 200, so that the transistor 210 may provide a driving current to the first electrode 510 to participate in driving the light emitting unit 610 to emit light. For example, the first electrode 510 may be connected to the source and drain 213 of some transistors 210 in the driving circuit 200, so that the first electrode 510 can be electrically connected to the semiconductor structure 211 through the source and drain 213.

For example, the first conductive portion 512a can be spaced apart from the first light shielding portion 310, so that the first conductive structure 512 is not likely to be short-circuited with the first light shielding portion 310, thereby reducing signal crosstalk in the display panel 10. In some embodiments of the present application, the first electrode 510 can be used to limit light from irradiating to the gap between the first conductive structure 512 and the first light shielding portion 310 in the first type of opening 311a, so that light is not likely to irradiate to the semiconductor structure 211 through the gap between the first conductive structure 512 and the first light shielding portion 310, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.

[0199] By arranging at least a portion of the first segment 231 to be located on a side of the first light shielding portion 310 away from the substrate 110 and extending in a direction parallel to the plane where the substrate 110 is located, and arranging at least a portion of the second segment 232 to be located between the first light shielding portion 310 and the substrate 110 and extending along the thickness direction X of the display panel 10, at least a portion of the signal line 230 can be better extended to the side of the first light shielding portion 310 away from the substrate 110, so that the arrangement of at least a portion of the signal line 230 is not easy to interfere with the arrangement of other devices between the first light shielding portion 310 and the substrate 110.

[0200] In some optional embodiments, the first connecting opening 311 may include a second-type opening 311b, and the signal line 230 includes a first-type signal line 230a extending along the thickness direction X of the display panel 10 and passing through the second-type opening 311b, so that the first-type signal line 230a can extend to the side of the first light-shielding portion 310 away from the substrate 110, so that the arrangement of the first-type signal line 230a is not easy to interfere with the arrangement of other devices between the first light-shielding portion 310 and the substrate 110.

[0201] Optionally, the number of the first type signal lines 230a may be at least two. Optionally, at least two first type signal lines 230a may be arranged side by side in a direction parallel to the plane where the substrate 110 is located.

For example, the first segment 231 of the first type signal line 230a may be located between the sixth insulating layer 170 and the seventh insulating layer 180.

[0203] Optionally, the first segment 231 of the first signal line 230a can be set in the same layer and material as the second conductive part 512b, so that in the preparation process of the display panel 10, the second conductive part 512b and the first segment 231 of the first signal line 230a can be prepared using the same preparation equipment in the same preparation step, which can greatly improve the preparation efficiency of the display panel 10.

[0204] Optionally, the first type signal line 230a is spaced apart from the first light shielding portion 310. For example, the second segment 232 of the first type signal line 230a can be spaced apart from the first light shielding portion 310, so that the first type signal line 230a is not easily short-circuited with the first light shielding portion 310, thereby reducing signal crosstalk in the display panel 10.

[0205] In some optional embodiments, the orthographic projection of the first electrode 510 on the substrate 110 at least partially overlaps with the orthographic projection of the second type of opening 311b on the substrate 110, so that the first electrode 510 can also be used to limit the light from irradiating to the second type of opening 311b, making it difficult for the light to irradiate to the semiconductor structure 211 through the second type of opening 311b, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.

[0206] In some optional embodiments, the orthographic projection of the first segment 231 on the substrate 110 at least partially overlaps with the orthographic projection of the first connecting opening 311 on the substrate 110, so that the first segment 231 of the signal line 230 can be used to limit light from irradiating toward the first connecting opening 311, making it difficult for light to irradiate toward the semiconductor structure 211 through the first connecting opening 311, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.

[0207] Optionally, the orthographic projection of the first segment 231 on the substrate 110 at least partially overlaps with the orthographic projection of the second type of opening 311b on the substrate 110, so that the first segment 231 can be used to limit light from irradiating to the second type of opening 311b, making it difficult for light to irradiate to the semiconductor structure 211 through the second type of opening 311b.

[0208] Exemplarily, the orthographic projection of the second type opening 311 b on the substrate 110 may be located within the orthographic projection of the first segment 231 on the substrate 110 , so that the first segment 231 may have a larger size to shield the light irradiating the second type opening 311 b .

[0211] Optional, such as Figure 3As shown, the orthographic projection edge of the first segment 231 on the substrate 110 can be connected to the orthographic projection edge of the first electrode 510 on the substrate 110, and the first electrode 510 and the first segment 231 can be used together to limit light from irradiating to the second type of opening 311b, and make it difficult for the first electrode 510 to have a large size, which can better improve the transmittance of the display panel 10.

[0216] In this optional embodiment, by providing a shielding portion 231b with a larger line width, the shielding portion 231b can have a larger size to shield the light irradiating the first communication opening 311. By providing a wiring portion 231a with a smaller size, the arrangement of the wiring portion 231a can be facilitated, so that the first segment 231 is not likely to interfere with other devices, and the wiring portion 231a of the first segment 231 is not likely to shield too much light, which can help improve the light transmittance of the display panel 10.

[0232] Optionally, at least a portion of the first segment 231 of the signal line 230 may extend through the second communication opening 321 .

[0233] Optionally, at least one second communication opening 321 penetrates the second light shielding portion 320 along a direction parallel to the plane where the substrate 110 is located, and / or the first light shielding portion 310 and the second light shielding portion 320 jointly enclose at least one second communication opening 321 .

[0234] Optionally, there may be a plurality of second communication openings 321 , and the plurality of second communication openings 321 are distributed at intervals around the semiconductor structure 211 .

[0235] In these optional embodiments, by providing the second communication opening 321 , the signal line 230 located on the peripheral side of the semiconductor structure 211 can be led out of the light shielding structure 300 through the second communication opening 321 , which can facilitate the arrangement of the signal line 230 .

[0236] Optionally, the signal line 230 also includes a second type of signal line 230b, which may include a first segment 231. The first segment 231 of the second type of signal line 230b extends through the second connecting opening 321, so that the second type of signal line 230b can be led out of the shading structure 300 through the second connecting opening 321, which can facilitate the arrangement of the second type of signal line 230b.

[0237] Optionally, the signal line 230 may include at least two second-type signal lines 230 b. Optionally, the at least two second-type signal lines 230 b may be arranged side by side in a direction parallel to the plane where the substrate 110 is located.

[0239] Optionally, at least part of the second light shielding portion 320 is located between the first segment 231 of the signal line 230 and the substrate 110, and / or, at least part of the second light shielding portion 320 is located between the first segment 231 of the signal line 230 and the first light shielding portion 310 (not shown in the figure).

[0240] Optionally, the orthographic projection of the second light shielding portion 320 on the substrate 110 partially overlaps with the orthographic projection of the first segment 231 of the signal line 230 on the substrate 110 .

[0241] For example, at least part of the second light shielding portion 320 may be located between the first segment 231 of the second type signal line 230b and the substrate 110, and / or, at least part of the second light shielding portion 320 may be located between the first segment 231 of the second type signal line 230b and the first light shielding portion 310 (not shown in the figure).

[0242] Exemplarily, the second light shielding portion 320 located between the first segment 231 of the signal line 230 and the substrate 110 may extend through the first insulating layer 120, the second insulating layer 130, and the third insulating layer 140. Exemplarily, the second light shielding portion 320 not located on both sides of the second connecting opening 321 in the thickness direction X of the display panel 10 may extend through the first insulating layer 120, the second insulating layer 130, the third insulating layer 140, the fourth insulating layer 150, and the fifth insulating layer 160.

[0243] In these optional embodiments, by reasonably setting the location and size of the second light shielding portion 320 , the shielding capability of the second light shielding portion 320 against the light directed toward the side of the semiconductor structure 211 can be improved.

[0244] In some optional embodiments, the number of the signal lines 230 is at least two, and the orthographic projections of the at least two signal lines 230 on the substrate 110 at least partially overlap.

[0245] Optionally, the orthographic projections of the first segments 231 of at least two signal lines 230 on the substrate 110 at least partially overlap.

[0247] Optionally, the orthographic projection of the first segment 231 of the first-type signal line 230 a on the substrate 110 may at least partially overlap with the orthographic projection of the first segment 231 of the second-type signal line 230 b on the substrate 110 .

[0248] In these optional embodiments, by arranging the orthographic projections of at least two signal lines 230 on the substrate 110 to at least partially overlap, the arrangement area of ​​the signal lines 230 in the direction parallel to the plane where the substrate 110 is located is smaller, so that the blocking effect of the signal lines 230 on light in the thickness direction X of the display panel 10 can be better reduced, so that the display panel 10 can have better light transmittance, for example, the display panel 10 in the second display area AA2 can have better light transmittance.

[0250] like Fig.10 As shown, optionally, the orthographic projections of the first segments 231 of at least two signal lines 230 on the substrate 110 overlap and extend in different directions. At the overlapped portion of the first segments 231 of the two signal lines 230, the signal lines 230 have less effect on blocking light, and at the non-overlapped portion of the first segments 231 of the two signal lines 230, the first segments 231 of the two signal lines 230 can be extended and arranged more freely, which can facilitate the connection of the signal lines 230 with corresponding devices.

[0252] like Fig.11 As shown, in some optional embodiments, the orthographic projections of the first segments 231 of at least two second-type signal lines 230 b on the substrate 110 may at least partially overlap.

[0253] By arranging at least two second-type signal lines 230b so that their orthographic projections on the substrate 110 at least partially overlap, the arrangement area of ​​the second-type signal lines 230b in a direction parallel to the plane where the substrate 110 is located is smaller, so that the blocking effect of the second-type signal lines 230b on light in the thickness direction X of the display panel 10 can be better reduced, so that the display panel 10 can have better light transmittance.

[0254] Fig.12 It is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application.

[0255] like Fig.12 As shown, in some optional embodiments, the second segment 232 may be at least partially located on a side of the second communication opening 321 facing the semiconductor structure 211 .

[0256] Optionally, the second-type signal line 230 b may also include a second segment 232 , and the first segment 231 of the second-type signal line 230 b may be connected to the second segment 232 to facilitate the arrangement of the second-type signal line 230 b .

[0257] Optionally, the second segment 232 of the first type signal line 230a may be at least partially located on the side of the second connecting opening 321 facing the semiconductor structure 211, and / or the second segment 232 of the second type signal line 230b may be at least partially located on the side of the second connecting opening 321 facing the semiconductor structure 211.

[0258] By setting the second segment 232 to be at least partially located on the side of the second connecting opening 321 facing the semiconductor structure 211, the second segment 232 can be relatively close to the semiconductor structure 211, so that the second segment 232 can be used to block at least part of the light irradiated to the side of the semiconductor structure 211, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.

[0259] Fig.13 It is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application.

[0260] like Fig.13 As shown, in some optional embodiments, the signal line 230 includes an adjacent upper signal line UL and a lower signal line DL, and the upper signal line UL and the lower signal line DL each include a first segment 231 and a second segment 232, the first segment 231 of the upper signal line UL is located on the side of the first segment 231 of the lower signal line DL away from the substrate 110, and the second segment 232 of the lower signal line DL extends through at least a portion of the film layer in the substrate 100 between the second segment 232 of the upper signal line UL and the substrate 110.

[0261] Exemplarily, when the first insulating layer 120 and the second insulating layer 130 are located between the second segment 232 of the upper signal line UL and the substrate 110 , the second segment 232 of the lower signal line DL may extend through at least one of the first insulating layer 120 and the second insulating layer 130 .

[0262] Optionally, the upper signal line UL and the lower signal line DL may be two adjacent signal lines 230 in any of the aforementioned embodiments. For example, the upper signal line UL may be a first-type signal line 230a, and the lower signal line DL may be a second-type signal line 230b adjacent to the upper signal line UL. Or, for example, the upper signal line UL and the lower signal line DL may be two adjacent first-type signal lines 230a, and among the two adjacent first-type signal lines 230a, the upper signal line UL may be a first-type signal line 230a that is relatively far away from the substrate 110, and the lower signal line DL may be a first-type signal line 230a that is relatively close to the substrate 110. Or, for example, the upper signal line UL and the lower signal line DL may be two adjacent second-type signal lines 230b, and among the two adjacent second-type signal lines 230b, the upper signal line UL may be a second-type signal line 230b that is relatively far away from the substrate 110, and the lower signal line DL may be a second-type signal line 230b that is relatively close to the substrate 110.

[0263] Optionally, an orthographic projection of the first segment 231 of the upper signal line UL on the substrate 110 at least partially overlaps with an orthographic projection of the first segment 231 of the lower signal line DL on the substrate 110 .

[0264] Optionally, on the side of the second light shading portion 320 facing the semiconductor structure 211, the second segment 232 of the upper signal line UL may be located on the side of the second segment 232 of the lower signal line DL facing the semiconductor structure 211; and on the side of the second light shading portion 320 away from the semiconductor structure 211, the second segment 232 of the upper signal line UL may be located on the side of the second segment 232 of the lower signal line DL away from the semiconductor structure 211, thereby facilitating the arrangement of the upper signal line UL across the lower signal line DL, and reducing the interference effect between the upper signal line UL and the lower signal line DL.

[0265] In these optional embodiments, by setting the second segment 232 of the lower signal line DL closer to the side of the substrate 110 to extend through at least a portion of the film layer between the second segment 232 of the upper signal line UL and the substrate 110 in the substrate 100, the second segment 232 of the lower signal line DL closer to the side of the substrate 110 can be extended to be closer to the substrate 110, so that the second segments 232 of the upper signal line UL and the lower signal line DL can both better participate in blocking light from irradiating to the side of the semiconductor structure 211, that is, the signal line 230 as a whole can have a larger size in the thickness direction X of the display panel 10 to block light from irradiating to the side of the semiconductor structure 211, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.

[0266] Optionally, a second light-shielding portion 320 is provided between the first light-shielding portion 310 and the substrate 110, and between at least a portion of the film layers in the substrate 100 where the second segment 232 is not provided, so that the light irradiating to the side of the semiconductor structure 211 can be better shielded by the second light-shielding portion 320 at the position where the second segment 232 is provided.

[0267] In some optional embodiments, the number of the second segments 232 is at least two, and at least part of the first segment 231 is connected between two adjacent second segments 232 .

[0268] Specifically, the number of the second segments 232 of a single signal line 230 may be at least two, and the first segment 231 of at least one signal line 230 may be connected between two adjacent second segments 232 .

[0269] Optionally, a portion of the second segment 232 may be located on a side of the second communication opening 321 facing the semiconductor structure 211 , and another portion of the second segment 232 may be located on a side of the second communication opening 321 away from the semiconductor structure 211 .

[0270] Optionally, at least a portion of the second light shielding portion 320 is located between two adjacent second segments 232 .

[0271] In these optional embodiments, by setting the number of second segments 232 to at least two, and setting at least a portion of the first segment 231 to be connected between two adjacent second segments 232, the signal line 230 can be bridge-shaped, and the signal line 230 can be better arranged across the shading structure 300. For example, the first type of signal line 230a can be better arranged across the first shading portion 310 and the second shading portion 320, and the second type of signal line 230b can be better arranged across the second shading portion 320.

[0272] In some optional embodiments, the sizes of the two second segments 232 connected to the two sides of the first segment 231 in the thickness direction X of the display panel 10 may be different.

[0273] Exemplarily, the second segment 232 connected to the first segment 231 close to the side of the semiconductor structure 211 may have a first length in the thickness direction X of the display panel 10, and the second segment 232 connected to the first segment 231 close to the side of the semiconductor structure 211 may have a second length in the thickness direction X of the display panel 10. The first length may be greater than the second length or the first length may be less than the second length.

[0274] In these optional embodiments, when the first length is greater than the second length, the second segment 232 closer to the semiconductor structure 211 may have a larger size in the thickness direction X of the display panel 10, which can facilitate the second segment 232 to block the light, so that the light is not easy to irradiate the side of the semiconductor structure 211. When the second length is greater than the first length, it can facilitate the arrangement of the second light shielding portion 320 away from the second segment 232 on the side of the semiconductor structure 211, reducing the difficulty of arranging the signal line 230.

[0275] In some optional embodiments, the light shielding structure 300 further includes a third light shielding portion 330 disposed between the semiconductor structure 211 and the substrate 110 , and the orthographic projection of the semiconductor structure 211 on the substrate 110 at least partially overlaps with the orthographic projection of the third light shielding portion 330 on the substrate 110 .

[0276] Optionally, the third light shielding portion 330 may be disposed between the substrate 110 and the first insulating layer 120 .

[0277] In these optional embodiments, the third light shielding portion 330 can be used to shield light from the side of the substrate 110 toward the semiconductor structure 211 , which can improve the working stability of the semiconductor structure 211 and thus improve the working stability of the display panel 10 .

[0278] Optionally, at least a portion of the second light shielding portion 320 is connected to the third light shielding portion 330 , so that the light shielding structure 300 can be relatively continuous at the connection between the second light shielding portion 320 and the third light shielding portion 330 , so as to better enhance the light shielding effect of the light shielding structure 300 .

[0279] Optionally, the orthographic projection of the second light shielding portion 320 on the substrate 110 is located within the orthographic projection of the third light shielding portion 330 on the substrate 110, so that the third light shielding portion 330 can have a larger size to shield light.

[0298] Optionally, the material of the support column SPC may include an opaque material, for example, the material of the support column SPC may include a black glue material.

[0299] In these optional embodiments, by setting the orthographic projection of the support column SPC on the substrate 110 to at least partially overlap with the orthographic projection of the first connecting opening 311 on the substrate 110, the support column SPC can also be used to limit the light from irradiating to the first connecting opening 311, so that the light is not easily irradiated to the semiconductor structure 211 through the first connecting opening 311, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.

[0302] By setting at least a portion of the shading structure 300 between at least two adjacent signal lines 230 in the thickness direction X of the display panel 10, the shading structure 300 can better limit the light from shining toward the semiconductor structure 211 through the gap between at least two adjacent signal lines 230 in the thickness direction X of the display panel 10, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.

[0304] By arranging at least a portion of the second segment 232 located in the second display area AA2 to extend along the thickness direction X of the display panel 10 through the film layer where the semiconductor structure 211 is located and adjacent to the semiconductor structure 211, the second segment 232 can be used to block at least a portion of the light irradiated toward the side of the semiconductor structure 211, which can better improve the working stability of the semiconductor structure 211, thereby better improving the working stability of the display panel 10.
