Display panel

Abstract

The application discloses a display panel, which comprises an array substrate, the array substrate comprising a first substrate, a plurality of signal lines and a first light shielding layer. The first light shielding layer comprises a plurality of light shielding portions by forming the first light shielding layer on the signal lines. The light shielding portion comprises a first metal sub-portion, an insulating sub-portion and a second metal sub-portion which are sequentially stacked. The first metal sub-portion is at least partially overlapped with the insulating sub-portion and the second metal sub-portion on the first substrate. The light shielding portion covers at least part of the signal lines on the first substrate. Thus, the signal lines can be shielded by the light shielding portion formed by the metal material. Since the process precision of the metal material is high, the relative position of the light shielding portion and the signal lines can be prevented from being deviated. Thus, the shielding effect of the first light shielding layer on the signal lines can be improved, so that the reflectivity of the display panel can be reduced and the display effect of the display panel can be improved.

Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel. Background Technology

[0002] Liquid crystal displays (LCDs) are among the most widely used flat panel displays, and the LCD panel is the core component of an LCD. A traditional LCD panel typically consists of a color filter substrate, an array substrate, and a liquid crystal layer disposed between the two substrates. Its working principle involves placing liquid crystal molecules between two parallel glass substrates. Numerous vertical and horizontal fine wires are located between the two glass substrates. The direction of the liquid crystal molecules is controlled by whether or not electricity is applied, thus refracting light from the backlight module to produce an image. The array substrate contains a thin-film transistor array used to drive the rotation of the liquid crystal and control the display of each pixel, while the color filter substrate contains a color filter layer used to form the color of each pixel.

[0003] With the development of liquid crystal display technology, the color resist and black matrix of the color filter substrate are now fabricated on the array substrate to solve problems such as light leakage and color shift caused by insufficient alignment accuracy between the color filter substrate and the array substrate during cell alignment. However, due to the lower process precision of the black matrix, the relative position of the black matrix and the metal traces is prone to misalignment, resulting in poor shielding effect of the black matrix on the underlying metal traces. This leads to increased reflectivity of the display panel and affects the display effect.

[0004] Therefore, it is necessary to provide a display panel to improve this deficiency. Utility Model Content

[0005] Embodiments of this application provide a display panel that can reduce the reflectivity of the display panel.

[0006] To achieve the above objectives, according to a first aspect of this application, a display panel is provided, including a display area, the display panel including an array substrate, the array substrate comprising:

[0007] First substrate;

[0008] Multiple signal lines are disposed on the first substrate and located in the display area;

[0009] A first light-shielding layer is disposed on the signal line and includes a plurality of light-shielding portions. The orthogonal projection of the light-shielding portions on the first substrate covers at least a portion of the orthogonal projection of the signal line on the first substrate.

[0010] The light-shielding portion includes a first metal sub-part, an insulator portion, and a second metal sub-part stacked sequentially. The orthographic projection of the first metal sub-part on the first substrate at least partially overlaps with the orthographic projections of the insulator portion and the second metal sub-part on the first substrate.

[0011] Optionally, the multiple signal lines include data lines, and the multiple light-shielding portions include multiple first light-shielding portions, the orthographic projection of the first light-shielding portions on the first substrate covering the orthographic projection of the data lines on the first substrate.

[0012] Optionally, the multiple signal lines include scan lines, and the multiple light-shielding portions include multiple second light-shielding portions, the orthographic projection of the second light-shielding portions on the first substrate covering the orthographic projection of the scan lines on the first substrate.

[0013] Optionally, the lengths of the first metal sub-part, the insulator part, and the second metal sub-part are all greater than or equal to the dimension of the display area in the extension direction of the signal line.

[0014] Optionally, the thickness of the first metal sub-part is greater than the thickness of the second metal sub-part.

[0015] Optionally, the insulator portion and the second metal portion at least cover the top surface of the first metal portion.

[0016] Optionally, the insulator portion and the second metal portion cover one side of the first metal portion.

[0017] Optionally, the array substrate further includes a common electrode, which is connected to a DC signal, and the light-shielding part is electrically connected to the common electrode.

[0018] Optionally, the common electrode is disposed on the first light-shielding layer, and the common electrode is connected to the second metal sub-part;

[0019] Alternatively, the first light-shielding layer is disposed on the common electrode, and the first metal sub-part is connected to the common electrode.

[0020] Optionally, the display panel further includes a non-display area disposed around the display area, the insulator portion is provided with a through hole, the through hole is located at least in the non-display area, and the second metal portion is connected to the first metal portion through the through hole.

[0021] In the display panel of this application embodiment, a first light-shielding layer is formed on the signal line. The first light-shielding layer includes multiple light-shielding portions, each of which includes a first metal sub-part, an insulator portion, and a second metal sub-part stacked sequentially. The orthographic projection of the first metal sub-part on the first substrate at least partially overlaps with the orthographic projections of the insulator portion and the second metal sub-part on the first substrate, and the orthographic projection of the light-shielding portion on the first substrate covers at least a portion of the orthographic projection of the signal line on the first substrate. In this way, the light-shielding portion formed of metal material can block the signal line. Since the manufacturing process of metal material has high precision, the relative position of the light-shielding portion and the signal line can be avoided from shifting. This can improve the blocking effect of the first light-shielding layer on the signal line, thereby reducing the reflectivity of the display panel and improving the display effect of the display panel.

[0037] 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 them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0038] Embodiments of this application provide a display panel including a display area. The display panel includes an array substrate, which includes a first substrate, multiple signal lines, and a first light-shielding layer. The multiple signal lines are disposed on the first substrate and located in the display area. The first light-shielding layer is disposed on the signal lines and includes multiple light-shielding portions. The orthographic projection of each light-shielding portion on the first substrate covers at least a portion of the orthographic projection of the signal lines on the first substrate. Each light-shielding portion includes a first metal sub-part, an insulator sub-part, and a second metal sub-part stacked sequentially. The orthographic projection of the first metal sub-part on the first substrate at least partially overlaps with the orthographic projections of the insulator sub-part and the second metal sub-part on the first substrate.

[0039] In the embodiments of this application, a first light-shielding layer is formed on the signal line. The first light-shielding layer includes a plurality of light-shielding portions, each of which includes a first metal sub-part, an insulator portion, and a second metal sub-part stacked sequentially. The orthographic projection of the first metal sub-part on the first substrate at least partially overlaps with the orthographic projection of the insulator portion and the second metal sub-part on the first substrate, and the orthographic projection of the light-shielding portion on the first substrate covers at least a portion of the orthographic projection of the signal line on the first substrate. In this way, the light-shielding portion formed of metal material can be used to block the signal line. Since the manufacturing process of metal material has high precision, the relative position of the light-shielding portion and the signal line can be avoided from shifting. This can improve the blocking effect of the first light-shielding layer on the signal line, thereby reducing the reflectivity of the display panel and improving the display effect of the display panel.

[0040] like Figure 1 As shown, Figure 1 This is a top view of a display panel provided in an embodiment of this application. The display panel 100 includes a display area AA and a non-display area NA disposed around the periphery of the display area AA. The display area AA is an area for displaying images, and the display area AA may be provided with multiple pixel driving circuits and multiple sub-pixels. The non-display area NA is an area for placing peripheral circuits, which may include, but are not limited to, gate driving circuits.

[0041] Combination Figure 2 and Figure 3 As shown, Figure 2 A partial schematic diagram of the display area of ​​a first type of display panel provided for an embodiment of this application. Figure 3 The first type of display panel provided for embodiments of this application is along Figure 2 The diagram shows a cross-sectional view along the A-A' direction. The display panel 100 includes an array substrate 1, which includes a first substrate 11, multiple signal lines, and a first light-shielding layer 13. The multiple signal lines are disposed on the first substrate 11, and the first light-shielding layer 13 is disposed on the multiple signal lines. The first light-shielding layer 13 includes multiple light-shielding portions 130, the orthographic projection of which on the first substrate 11 covers at least a portion of the orthographic projection of the signal lines on the first substrate 11.

[0042] like Figure 3 As shown, the light-shielding portion 130 includes a first metal sub-portion 131, an insulator portion 132, and a second metal sub-portion 133 stacked sequentially. The orthographic projection of the first metal sub-portion 131 on the first substrate 11 at least partially overlaps with the orthographic projection of the insulator portion 132 and the second metal sub-portion 133 on the first substrate 11. The stacked light-shielding structure formed by the first metal sub-portion 131, the insulator portion 132, and the second metal sub-portion 133 can shield the signal lines to reduce the reflection of ambient light incident into the display panel, thereby reducing the reflectivity of the display panel.

[0043] In some embodiments, combined with Figure 2 As shown, the multiple signal lines include data lines (Data), and the display panel also includes multiple scan lines (Scan). The data lines (Data) extend vertically and are arranged at horizontal intervals. The scan lines (Scan) extend horizontally and are arranged at vertical intervals. The data lines (Data) and scan lines (Scan) are set on different layers and are arranged to intersect each other to define multiple sub-pixel areas within the display area AA.

[0044] In some embodiments, and Figure 2 As shown, the plurality of light-shielding portions 130 include a plurality of first light-shielding portions 130a, each of which is also composed of a first metal sub-portion 131, an insulator portion 132, and a second metal sub-portion 133 stacked sequentially. The first light-shielding portions 130a extend along the extension direction of the data line Data, and the plurality of first light-shielding portions 130a are arranged at intervals in a direction perpendicular to the extension direction of the data line Data. The orthographic projection of the first light-shielding portions 130a on the first substrate 11 covers the orthographic projection of the data line Data on the first substrate 11. In this way, by covering the data line Data with the first light-shielding portions 130a, the reflection of ambient light incident into the display panel by the data line Data can be reduced, thereby reducing the reflectivity of the display panel.

[0045] In some embodiments, the lengths of the first metal sub-part 131, the insulator part 132, and the second metal sub-part 133 are all greater than the dimensions of the display area AA in the direction of extension of the signal line.

[0046] In some embodiments, combined with Figures 1 to 3 As shown, the first metal sub-part 131, the insulator part 132, and the second metal sub-part 133 are all elongated strips, and the lengths of the first metal sub-part 131, the insulator part 132, and the second metal sub-part 133 are all greater than the size of the display area AA in the extension direction of the data line Data. The first metal sub-part 131, the insulator part 132, and the second metal sub-part 133 all extend from one end of the display area AA to the opposite end of the display area AA, passing through the entire display area to completely cover the data line Data located below it.

[0047] In some embodiments, the thickness of the first metal sub-part 131 is greater than the thickness of the second metal sub-part 133. By reducing the thickness of the second metal sub-part 133, the reflection of ambient light by the light-shielding part 130 can be reduced, thereby further reducing the reflectivity of the display panel.

[0048] In some embodiments, combined with Figure 2As shown, the display panel includes multiple sub-pixels SP. Each sub-pixel SP may include a driving transistor and a pixel electrode electrically connected to the driving transistor. Each sub-pixel is disposed within a corresponding sub-pixel area. The multiple sub-pixels SP may include a first sub-pixel SP1, a second sub-pixel SP2, and a third sub-pixel SP3. The first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 allow different colors of light to pass through. For example, the first sub-pixel SP1 allows red light to pass through, the second sub-pixel SP2 allows green light to pass through, and the third sub-pixel SP3 allows blue light to pass through. The first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3, which are adjacent to each other in the extension direction of the data line Data, constitute a pixel unit.

[0049] In some embodiments, such as Figure 2 As shown, in the extension direction of the scan line Scan, the sum of the distance between two adjacent first light-shielding parts 130a and the width of one of the first light-shielding parts 130a is set as the first distance D1, and the center distance between two adjacent sub-pixels is set as the second distance D2. The first distance D1 and the second distance D2 are equal. In this way, the first light-shielding part 130a can cover the area between two adjacent sub-pixels SP along the extension direction of the scan line Scan. On the one hand, it can ensure that the first light-shielding part 130a can cover the data line Data. On the other hand, it can ensure that the first light-shielding part 130a can cover the area where the corresponding color resists of two adjacent sub-pixels overlap, so as to prevent color mixing between two adjacent sub-pixels SP. This can improve the contrast of the display panel while reducing the reflectivity of the display panel.

[0050] In some embodiments, the array substrate 1 further includes a common electrode com, which is connected to a DC signal, and a light-shielding part 130 is electrically connected to the common electrode com. By connecting the light-shielding part 130 to a DC signal, the light-shielding part 130 has a constant potential. This not only allows the light-shielding part 130 to cover the signal lines, reducing the reflection of ambient light incident into the display panel and thus reducing the reflectivity of the display panel, but also allows the light-shielding part 130 to shield the signal lines, reducing the parasitic capacitance between the signal lines and the common electrode or pixel electrode. This reduces signal crosstalk and improves the display effect of the display panel.

[0051] In some embodiments, the first light-shielding layer 13 is disposed on the common electrode com, and the first metal sub-part 131 is connected to the common electrode com.

[0052] Combination Figure 2 and Figure 3The array substrate 1 includes a first substrate 11 and a first gate layer 16, a first gate insulating layer 17, an active layer 18, a second gate insulating layer 19, a second conductive layer 15, a first interlayer dielectric layer 101, a first conductive layer 12, a first insulating layer 102, a color filter layer 14, a planarization layer 103, a first electrode layer 104, a second insulating layer 105, a second electrode layer 106, a third insulating layer 107, and a first light-shielding layer 13, which are sequentially stacked on the first substrate 11. The first conductive layer 12 includes data lines (Data), and can also be considered as a source-drain layer. The second conductive layer 15 can be considered as a second gate layer. At least one of the first gate layer 16 and the second conductive layer 15 can include scan lines (Scan).

[0053] Combination Figure 2 and Figure 3 As shown, the first electrode layer 104 includes pixel electrodes, the second electrode layer 106 includes a common electrode com, the third insulating layer 107 is disposed on the second electrode layer 106, the first light-shielding layer 13 is disposed on the third insulating layer 107, and the first metal sub-part 131 is connected to the common electrode com through a via on the third insulating layer 107, so that the first metal sub-part 131 has the same potential as the common electrode com. In this way, the first metal sub-part 131 can shield the electric field of the data line Data, thereby reducing signal crosstalk and improving the display effect of the display panel.

[0054] In some other embodiments, the common electrode com can also be disposed on the first light-shielding layer 13. The common electrode can be connected to the second metal sub-part 133 of the light-shielding part 130 through a via, so that the second metal sub-part can shield the electric field of the data line Data, thereby reducing signal crosstalk and improving the display effect of the display panel.

[0055] In some embodiments, combined with Figure 3 As shown, the insulator part 132 is provided with a through hole H, and the second metal part 133 is connected to the first metal part 131 through the through hole H. In this way, the first metal part 131 and the second metal part 133 can simultaneously have the same potential as the common electrode com. This not only enables the light-shielding part 130 to shield the electric field of the data line Data, but also reduces the impedance of the common electrode com, thereby reducing the potential difference of the common electrode com in different areas and improving the uniformity of the brightness of the display panel.

[0056] In some embodiments, via H is provided at least in the non-display area NA. For example, via H can be provided in the non-display area NA on at least one side of the display area AA, via H can be provided in the non-display area NA surrounding the display area AA, or via H can be provided in both the display area AA and the non-display area NA. By electrically connecting the first metal sub-part 131 and the second metal sub-part 133 using via H, the same potential of the common electrode com can be applied to the first metal sub-part 131 and the second metal sub-part 133 simultaneously. This not only enables the light-shielding part 130 to shield the electric field of the data line Data, but also reduces the impedance of the common electrode com, thereby reducing the potential difference of the common electrode com in different areas and improving the uniformity of the brightness of the display panel.

[0057] In some embodiments, combined with Figure 3 As shown, the display panel 100 also includes an opposing substrate 2 and a liquid crystal layer 3. The opposing substrate 2 and the array substrate 1 are disposed at a distance from each other, and the liquid crystal layer 3 is disposed between the array substrate 1 and the opposing substrate 2.

[0058] like Figure 3 As shown, the opposing substrate 2 includes a second substrate 22 and a second light-shielding layer 21. The second light-shielding layer 21 is disposed on the second substrate 22 and includes a plurality of third light-shielding portions 211. The third light-shielding portions 211 extend along the extension direction of the scan line Scan. The orthogonal projection of the third light-shielding portions 211 on the first substrate 11 can cover the orthogonal projection of the scan line Scan on the first substrate 11. By using the third light-shielding portions 211 to cover the scan line Scan, the reflection of ambient light incident on the display panel by the scan line Scan can be reduced, thereby further reducing the reflectivity of the display panel.

[0059] In some embodiments, the material of the second light-shielding layer 21 includes resin, and the second light-shielding layer 21 can be considered as a black matrix.

[0060] Combination Figure 4 As shown, Figure 4 This is a schematic diagram illustrating the manufacturing process of the first light-shielding layer in a display panel provided for an embodiment of this application. The method for manufacturing the first light-shielding layer in the display panel includes the following steps:

[0061] Step S1: A first metal material is formed on the first substrate 11, and the first metal material is patterned to form a plurality of spaced first metal portions 1310.

[0062] Step S3: An insulating material 1320 is formed on the first substrate 11 and the first metal portion 1310, and a second metal material 1330 is formed on the insulating material.

[0063] Step S4: Form a photoresist layer on the second metal material 1330, expose the photoresist to form multiple photoresist patterns 4; etch the second metal material 1330 to form a second metal sub-part 133; remove the insulating material not covered by the second metal sub-part 133 to form an insulator part 132; remove the first metal part 1310 not covered by the second metal sub-part 133 to form a first metal sub-part 131, and obtain a first light-shielding layer.

[0064] Combination Figure 4 As shown, the insulator portion 132 and the second metal portion 133 cover the top surface of the first metal portion 131. The width of the first metal portion 131 is the same as that of the insulator portion 132 and the second metal portion 133, and is greater than the line width of the signal line. This ensures that the light-shielding portion 130 can completely cover the signal line.

[0065] like Figure 5 As shown, Figure 5 The first light-shielding layer in the display panel provided in the embodiment of this application is a film layer diagram. The first light-shielding layer 13 includes a plurality of first light-shielding portions 130a. The plurality of first light-shielding portions 130a extend longitudinally and are continuously disposed, and the plurality of first light-shielding portions 130a are arranged at intervals in the transverse direction.

[0066] In some embodiments, combined with Figure 6 As shown, Figure 6 This is a schematic diagram of the manufacturing process of another first light-shielding layer in a display panel provided for an embodiment of this application. The manufacturing method is the same as the manufacturing method provided in the above embodiment. The difference is that the first metal sub-part 131 and the second metal sub-part 133 overlap on the orthogonal projection portion of the first substrate 11. The insulator part 132 and the second metal sub-part 133 not only cover the top surface of the first metal sub-part 131, but also cover the side surface of the first metal sub-part 131. In this way, the signal lines can also be covered to reduce the reflectivity of the display panel, and the manufacturing process can also be simplified.

[0067] In some embodiments, combined with Figure 7 As shown, Figure 7 A schematic diagram illustrating the manufacturing process of another first light-shielding layer in a display panel provided for embodiments of this application. The method for manufacturing the first light-shielding layer in the display panel includes the following steps:

[0068] Step S1: A first metal material 1311, an insulating material 1320 and a second metal material 1330 are sequentially formed on the first substrate 11;

[0069] Step S2: Form a photoresist layer on the second metal material 1330, expose the photoresist to form multiple photoresist patterns 4; etch the second metal material 1330 to form a second metal sub-part 133; remove the insulating material 1320 not covered by the second metal sub-part 133 to form an insulator 132; remove the first metal material 1311 not covered by the second metal sub-part 133 to form a first metal sub-part 131, and obtain a first light-shielding layer.

[0070] In this embodiment, the first metal sub-part 131, the insulator part 132, and the second metal sub-part 133 are formed by a single exposure and etching process, which can prevent misalignment between the first metal sub-part 131 and the second metal sub-part 133, thereby further reducing the reflectivity of the display panel.

[0071] Combination Figure 8 and Figure 9 As shown, Figure 8 This is a partial schematic diagram of the display area of ​​a second type of display panel provided for an embodiment of this application. Figure 9 A film layer diagram of the first light-shielding layer in a second type of display panel provided for embodiments of this application, the structure of which is similar to... Figure 2 The structure of the first type of display panel shown is roughly the same, the difference being that: the signal lines include multiple scan lines (Scan), and the multiple light-shielding portions 130 include multiple second light-shielding portions 130b. The second light-shielding portions 130b extend along the extension direction of the scan lines (Scan), and the multiple second light-shielding portions 130b are arranged at intervals along the extension direction of the data lines (Data). The orthographic projection of the second light-shielding portions 130b on the first substrate 11 covers the orthographic projection of the scan lines (Scan) on the first substrate 11. In this way, the second light-shielding portions 130b can cover the scan lines (Scan) to reduce the reflection of ambient light incident on the display panel, thereby reducing the reflectivity of the display panel.

[0072] In some embodiments, the second light-shielding layer 21 on the opposing substrate 2 includes a plurality of third light-shielding portions 211. The third light-shielding portions 211 extend along the extension direction of the data line Data. The orthographic projection of the third light-shielding portions 211 on the first substrate 11 can cover the orthographic projection of the data line Data on the first substrate 11. By using the third light-shielding portions 211 to cover the data line Data, the reflection of ambient light incident on the display panel by the data line Data can be reduced, thereby further reducing the reflectivity of the display panel.

[0073] In some embodiments, combined with Figure 8As shown, in the extension direction of the data line Data, the sum of the distance between two adjacent first light-shielding parts 130a and the width of one of the first light-shielding parts 130a is set as the third distance D3, and the center distance between two adjacent sub-pixels is set as the fourth distance D4. The third distance D3 and the fourth distance D4 are equal. In this way, the first light-shielding part 130a can cover the area between two adjacent sub-pixels SP along the extension direction of the data line Data. On the one hand, it can ensure that the first light-shielding part 130a can cover the scan line Scan. On the other hand, it can ensure that the first light-shielding part 130a can cover the area where the corresponding color resists of two adjacent sub-pixels overlap, so as to prevent color mixing between two adjacent sub-pixels SP. This can improve the contrast of the display panel while reducing the reflectivity of the display panel.

[0074] In some embodiments, combined with Figure 10 and Figure 11 As shown, Figure 10 A partial schematic diagram of the display area of ​​a third type of display panel provided in an embodiment of this application. Figure 11 A film layer diagram of the first light-shielding layer in a third type of display panel provided for embodiments of this application, the structure of which is similar to... Figure 2 The structure of the first type of display panel shown is roughly the same, except that: the plurality of light-shielding portions 130 include a plurality of first light-shielding portions 130a and a plurality of second light-shielding portions 130b, which are arranged intersectingly. The orthographic projection of the first light-shielding portion 130a on the first substrate 11 covers the orthographic projection of the data line Data on the first substrate 11, and the orthographic projection of the second light-shielding portion 130b on the first substrate 11 covers the orthographic projection of the scan line Scan on the first substrate 11. In this way, the first light-shielding portion 130a and the second light-shielding portion 130b can cover the data line Data and the scan line Scan respectively, thus eliminating the need for a second light-shielding layer on the opposing substrate, thereby simplifying the film layer structure of the display panel.

[0075] Based on the display panel provided in the above embodiments of this application, embodiments of this application also provide a display device. Please refer to [link to relevant documentation]. Figure 12 , Figure 12 This is a schematic diagram of a display device provided in an embodiment of this application. The display device 1000 includes a display panel 100 and a housing 200, with the display panel 100 disposed on the housing 200. The display panel 100 can be any of the display panels provided in the above embodiments. The display device provided in the embodiments of this application can achieve the same technical effects as the display panels provided in any of the above embodiments, and will not be described in detail here.

[0076] The beneficial effects of the embodiments of this application are as follows: In the display panel of the embodiments of this application, by forming a first light-shielding layer on the signal line, the first light-shielding layer includes a plurality of light-shielding parts, each of which includes a first metal sub-part, an insulator part, and a second metal sub-part stacked sequentially. The orthographic projection of the first metal sub-part on the first substrate at least partially overlaps with the orthographic projection of the insulator part and the second metal sub-part on the first substrate, and the orthographic projection of the light-shielding part on the first substrate covers at least part of the orthographic projection of the signal line on the first substrate. In this way, the light-shielding part formed of metal material can be used to block the signal line. Since the manufacturing process of metal material has high precision, the relative position of the light-shielding part and the signal line can be avoided from shifting. This can improve the blocking effect of the first light-shielding layer on the signal line, thereby reducing the reflectivity of the display panel and improving the display effect of the display panel.
