Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display panel, a manufacturing method of the display panel and a display device. BACKGROUND

[0002] Liquid crystal display device is one of the most widely used flat panel display devices, and a liquid crystal display panel is a core component of the liquid crystal display device. A traditional liquid crystal display panel is usually composed of a color film substrate, an array substrate and a liquid crystal layer arranged between the two substrates. Its working principle is to place liquid crystal molecules between two parallel glass substrates, and there are many vertical and horizontal fine wires between the two glass substrates. By controlling the power on or off, the liquid crystal molecules change direction to refract the light of the backlight module to produce a picture. The array substrate is provided with a thin film transistor array for driving the rotation of the liquid crystal and controlling the display of each pixel, and the color film substrate is provided with a color filter layer for forming the color of each pixel.

[0003] With the development of liquid crystal display technology, the color resistance and black matrix of the color film substrate are now prepared on the array substrate to solve the problems of light leakage and color deviation caused by insufficient alignment accuracy when the color film substrate is aligned with the array substrate. Currently, the same shading effect can be achieved by replacing the black matrix with a metal shading structure, which is composed of two metal layers and an insulating layer sandwiched between the two metal layers. When the inorganic layer is formed, if there is a large area of metal on the substrate, the large area of metal is prone to arc discharge, which causes damage to the substrate and the target material. Therefore, the lower metal layer on the substrate needs to be etched first to form a metal pattern to reduce the metal area on the substrate, and then the insulating layer and the upper metal layer are deposited on the metal pattern in sequence, and the upper metal layer is etched again. Due to the deviation of the two etching processes, the relative position of the lower metal shading structure and the upper metal shading structure is shifted, which reduces the shielding effect of the metal shading structure on the lower metal wiring, and increases the reflectivity of the display panel, affecting the display effect of the display panel.

[0004] Therefore, it is necessary to provide a display panel, a manufacturing method of the display panel and a display device to improve this defect. SUMMARY

[0057]

[0058] ​Embodiments of the present application provide a display panel, the display panel comprising an array substrate, the array substrate comprising a first substrate, a first conductive layer and a first light shielding layer, the first conductive layer being disposed on the first substrate, the first conductive layer comprising a plurality of first signal lines in a display area, the first signal lines extending along a first direction, the first light shielding layer being disposed on the first conductive layer, the first light shielding layer comprising a plurality of first light shielding portions, the first light shielding portions extending along the first direction, a projection of the first light shielding portions on the first substrate covering a projection of at least part of the first signal lines on the first substrate, the first light shielding portions comprising a plurality of first metal sub-portions and at least one second metal sub-portion, the plurality of first metal sub-portions being arranged at intervals along the first direction, a projection of the first metal sub-portion and the second metal sub-portion on the first substrate at least partially overlapping.

[0059] In embodiments of the present application, the plurality of first metal portions are formed by first patterning the first metal film, so as to reduce the area of the metal material on the first substrate when the metal material is deposited, and then the insulating film and the second metal film are sequentially formed on the first metal portions, so as to avoid the situation that the arc discharge caused by the large-area metal during the formation of the insulating material damages the first substrate and the target material; the second metal sub-portion is formed by patterning the second metal film, and the insulating film and the first metal portion not covered by the second metal sub-portion are removed, so as to form the insulating sub-portion and the first metal sub-portion, so that the projection of the first metal sub-portion on the first substrate is located within the projection of the second metal sub-portion on the first substrate, and the relative position of the first metal sub-portion and the second metal sub-portion is prevented from deviating, so as to improve the light shielding effect of the edge of the first light shielding portion on the underlying first signal line, reduce the reflectivity of the display panel, and improve the display effect of the display panel.

[0060] As shown in Figure 1 , Figure 1 the top view of the display panel provided by embodiments of the present application, the display panel comprising a display area AA and a non-display area NA disposed at the periphery of the display area AA, the display area AA being an area for displaying a picture, and the display area AA can be provided with a plurality of pixel driving circuits and a plurality of sub-pixels. The non-display area NA is an area for placing peripheral circuits, and the peripheral circuits can include but are not limited to gate driving circuits.

[0061] As shown in Figure 2 and Figure 3 , Figure 2 the partial schematic view of the display area of the first display panel provided by embodiments of the present application, Figure 3 the partial schematic view of the display area of the first display panel provided by embodiments of the present application, Figure 2The cross-sectional view along the A-A' direction shown indicates that the display panel 100 includes an array substrate 1. The array substrate 1 includes a first substrate 11, a first conductive layer 12, and a first light-shielding layer 13. The first conductive layer 12 is disposed on the first substrate 11 and includes multiple first signal lines 121 located in the display area AA. The first light-shielding layer 13 is disposed on the first conductive layer 12 and includes multiple first light-shielding portions 130. The first light-shielding portions 130 extend along the first direction Y, and the extension direction of the first signal lines 121 is parallel to the first light-shielding layer AA. Figure 2 As shown in the first direction Y, a plurality of first light-shielding parts 130 are along Figure 2 The second direction X is arranged at intervals as shown. The first direction Y is different from the second direction X and is perpendicular to the thickness direction of the display panel. The first direction Y can be perpendicular to the second direction X.

[0062] Combination Figure 2 to Figure 4 As shown, Figure 4 The first type of display panel provided for embodiments of this application is along Figure 2 The cross-sectional view along the B-B' direction shows that the orthographic projection of the first light-shielding portion 130 on the first substrate 11 covers at least a portion of the orthographic projection of the first signal line 121 on the first substrate 11. The first light-shielding portion 130 includes a plurality of first metal sub-parts 131, at least one insulator portion 132, and at least one second metal sub-part 133. The plurality of first metal sub-parts 131 are arranged at intervals along the first direction Y, and in the second direction X, the ends of two adjacent first metal sub-parts 131 are flush. The orthographic projections of the first metal sub-parts 131 on the first substrate 11 at least partially overlap with the orthographic projections of the second metal sub-parts 133 on the first substrate 11, and the orthographic projections of the insulator portion 132 on the first substrate 11 at least partially overlap with the orthographic projections of the second metal sub-parts 133 on the first substrate 11.

[0063] In this embodiment, by making the orthographic projection of the first metal sub-part 131 on the first substrate 11 at least partially overlap with the orthographic projection of the second metal sub-part 133 on the first substrate 11, deviation between the first metal sub-part 131 and the second metal sub-part 133 can be avoided, thereby improving the light-shielding effect of the first light-shielding layer 13 and reducing the reflectivity of the display panel.

[0064] In some embodiments, the first light-shielding portion 130 includes a plurality of first metal sub-portions 131, an insulator portion 132, and a second metal sub-portion 133. The plurality of first metal sub-portions 131 are arranged at intervals along a first direction Y. The width of the first metal sub-portion 131 is less than or equal to the width of the second metal sub-portion 133. The orthographic projections of the plurality of first metal sub-portions 131 on the first substrate 11 are located within the orthographic projections of the corresponding second metal sub-portion 133 on the first substrate 11. The orthographic projection of a first signal line 121 on the first substrate 11 overlaps only with the orthographic projection of a first light-shielding portion 130 on the first substrate 11.

[0065] In the embodiment, on the one hand, by arranging the plurality of first metal sub-parts 131 in the first direction Y, the area of the metal film layer where the first metal sub-parts 131 are located can be reduced, so that the probability of arc discharge in the film forming of the insulating sub-part 132 due to the large area of the lower metal film layer, which causes damage to the first substrate 11 and the target material, can be reduced; on the other hand, by arranging the orthographic projection of the plurality of first metal sub-parts 131 on the first substrate 11 in the orthographic projection of the corresponding same second metal sub-part 133 on the first substrate 11, the area between the adjacent first metal sub-parts 131 is covered by the second metal sub-part 133, so that the light shielding area of the first light shielding layer 13 can be increased, thereby further reducing the reflectivity of the display panel.

[0066] In some embodiments, in combination with Figure 2 to Figure 4 As shown, the side surface of the first metal sub-part 131 in the second direction X is a vertical surface, the side surface of the second metal sub-part 133 in the second direction X is also a vertical surface, the side surface of the first metal sub-part 131 in the second direction X is flush with the side surface of the same side of the second metal sub-part 133, and the width of the first metal sub-part 131 in the second direction X is equal to the width of the second metal sub-part 133 in the second direction X, so as to avoid the relative position of the first metal sub-part 131 and the second metal sub-part 133 from being offset, thereby improving the light shielding effect of the first light shielding layer, reducing the reflectivity of the display panel, and improving the display effect of the display panel.

[0067] In some embodiments, in combination with Figure 5 As shown, Figure 5 A second display panel provided by the embodiment of the present application is shown in a cross-sectional view along the B-B' direction, which has substantially the same structure as the display panel shown in Figure 2 to Figure 4 As shown, the side surface of the first metal sub-part 131 in the second direction X is a vertical surface, the side surface of the second metal sub-part 133 in the second direction X is also a vertical surface, the side surface of the first metal sub-part 131 in the second direction X is flush with the side surface of the same side of the second metal sub-part 133, and the width of the first metal sub-part 131 in the second direction X is equal to the width of the second metal sub-part 133 in the second direction X, so as to avoid the relative position of the first metal sub-part 131 and the second metal sub-part 133 from being offset, thereby improving the light shielding effect of the first light shielding layer, reducing the reflectivity of the display panel, and improving the display effect of the display panel.

[0068] In some embodiments, as Figure 5As shown, the side surface of the first metal sub-section 131 and the side surface of the second metal sub-section 133 each has a certain slope, and the bottom of the side surface of the first metal sub-section 131 is beyond the bottom of the side surface of the second metal sub-section 133. In this structure, the width of the first metal sub-section 131 is greater than the width of the second metal sub-section 133, so that the orthographic projection of the first metal sub-section 131 on the first substrate 11 partially overlaps the orthographic projection of the second metal sub-section 133 on the first substrate 11, so that the relative position of the first metal sub-section and the second metal sub-section can also be prevented from deviating, so that the light shielding effect of the first light shielding layer can be improved, the reflectivity of the display panel can be reduced, and the display effect of the display panel can be improved.

[0069] In some embodiments, in combination with Figure 2 and Figure 3 As shown, each first light shielding section 130 includes a plurality of first metal sub-sections 131, an insulating sub-section 132, and a second metal sub-section 133. The plurality of first metal sub-sections 131 in the same first light shielding section 130 are arranged in the same column along the first direction Y, and the plurality of first light shielding sections 130 are arranged along the second direction X. In the second direction X, the insulating sub-section 132 of one of the two adjacent first light shielding sections 130 is arranged to be spaced apart from the insulating sub-section 132 of the other first light shielding section 130.

[0070] In some embodiments, in combination with Figure 1 to Figure 3 As shown, each first light shielding section 130 can extend from one end of the display area AA to the other end of the display area AA along the first direction Y, and the plurality of first metal sub-sections 131 in each column can be provided with only one corresponding insulating sub-section 132 and one second metal sub-section 133. The orthographic projection of all the first metal sub-sections 131 in the same column on the first substrate 11 is located within the orthographic projection of the same second metal sub-section 133 on the first substrate 11.

[0071] In other embodiments, at least two first light shielding sections 130 are arranged to be spaced apart along the first direction Y, and each first light shielding section 130 can include at least two first metal sub-sections 131, an insulating sub-section 132, and a second metal sub-section 133. By covering 2 or more first metal sub-sections 131 with the first second metal sub-section 133, the light shielding area of the first light shielding layer 13 can also be increased, so that the reflectivity of the display panel can be further reduced, and the display effect of the display panel can be improved.

[0072] In some embodiments, in combination with Figure 2 and Figure 3As shown, the width of the first light-shielding part 130 is greater than or equal to the line width of the first signal line 121. On the one hand, by covering the edge of the first signal line 121 with the first light-shielding part 130, light leakage at the edge of the first signal line 121 can be prevented. On the other hand, the first light-shielding part 130 can also shield the electric field of the first signal line 121, thereby reducing the parasitic capacitance between the first signal line 121 and the common electrode or pixel electrode, and reducing the impact of the voltage fluctuation of the first signal line 121 being lower than the potential of the common electrode or pixel electrode, thereby improving the display effect of the display panel.

[0073] In some embodiments, combined with Figure 2 and Figure 3 As shown, the distance between the edge of the first light-shielding portion 130 and the edge of the first signal line 121 in the linewidth direction of the first signal line 121 is a third distance D3, which is greater than or equal to 0.3 micrometers. For example, the distance between the edge of the first light-shielding portion 130 and the edge of the first signal line 121 in the linewidth direction of the first signal line 121 can be 0.3 micrometers, 0.4 micrometers, 0.5 micrometers, 0.8 micrometers, 1 micrometer, 1.2 micrometers, 1.5 micrometers, 1.7 micrometers, or 2 micrometers, etc.

[0074] It should be noted that if the distance between the edge of the first light-shielding part 130 and the edge of the first signal line 121 in the linewidth direction of the first signal line 121 is too small, and if the position of the first light-shielding part 130 deviates, the edge of the first signal line 121 may be exposed. This will not only increase the reflectivity of the display panel but also weaken the shielding effect on the electric field of the first signal line 121, resulting in light leakage in the display panel. In this embodiment, by limiting the distance between the edge of the first light-shielding part 130 and the edge of the first signal line 121 in the linewidth direction of the first signal line 121 to more than 0.3 micrometers, even if the position of the first light-shielding part 130 deviates, it can be ensured that the first light-shielding part 130 can cover the first signal line 121. This can improve the light-shielding effect of the first light-shielding layer 13, thereby further reducing the reflectivity of the display panel and improving the display effect of the display panel.

[0075] In some embodiments, such as Figure 2 As shown, the array substrate 1 includes multiple data lines (Data) and multiple scan lines (Scan). The multiple data lines (Data) are arranged along... Figure 2 Extending in the longitudinal direction as shown, and along Figure 2 As shown, multiple scan lines are arranged at intervals in the lateral direction and extend in the lateral direction and are arranged at intervals in the longitudinal direction. Data lines and scan lines are set in different layers. The orthogonal projections of multiple data lines and multiple scan lines on the first substrate 11 are arranged to intersect each other to define multiple sub-pixels SP.

[0076] In some embodiments, as shown in Figure 2 The plurality of sub-pixels SP include a first sub-pixel SP1, a second sub-pixel SP2 and a third sub-pixel SP3, which allow light of different colors 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 are alternately arranged along the first direction Y, and the first sub-pixel SP1, a second sub-pixel SP2 and a third sub-pixel SP3 adjacent in the first direction Y constitute a pixel unit.

[0077] In some embodiments, the plurality of first signal lines 121 include data lines Data or scan lines Scan.

[0078] In some embodiments, as shown in Figure 2 and Figure 3 The plurality of first signal lines 121 include data lines Data, and the orthographic projection of the first light shielding portion 130 on the first substrate 11 covers the orthographic projection of the data lines Data on the first substrate 11, so that the reflection of ambient light by the data lines Data can be reduced, thereby reducing the reflectivity of the display panel.

[0079] In some embodiments, as shown in Figure 2 and Figure 3 The array substrate 1 further includes a color filter layer 14 disposed between the first conductive layer 12 and the first light shielding layer 13, and the color filter layer 14 includes a plurality of filter portions 141. The orthographic projection of the first light shielding portion 130 on the color filter layer 14 covers the portion overlapping with two adjacent filter portions 141 in the second direction X, so that the occurrence of color mixing between the two adjacent sub-pixels SP can be prevented, thereby improving the contrast of the display panel.

[0080] In some embodiments, as shown in Figure 2 and Figure 3 In the first direction Y, the plurality of first metal sub-portions 131 are arranged at intervals, and a groove 142 is provided between two adjacent filter portions 141 to separate the two adjacent filter portions 141 in the first direction Y, so that a pixel driving circuit and a via for electrically connecting a pixel electrode and a driving thin film transistor can be placed in the region between the two adjacent filter portions 141. The groove 142 is located between two adjacent first metal sub-portions 131.

[0081] It should be noted that the terrain of the region between the two adjacent light filtering portions 141 in the first direction Y is recessed and forms a groove 142. If the first metal sub-portion 131 is formed in the groove 142, the topography of the first metal sub-portion 131 will be poor, and the risk of short circuit between the adjacent conductive film layers of the first metal sub-portion 131 will be increased. In the embodiment, the two adjacent first metal sub-portions 131 in the first direction Y are arranged on the two sides of the groove 142, so as to avoid the first metal sub-portion 131 from being formed in the groove 142. In this way, the risk of short circuit between the adjacent conductive film layers of the first metal sub-portion 131 can be reduced, and thus the production yield of the display panel can be improved.

[0082] In some embodiments, in combination with Figure 2 and Figure 3 As shown in FIG. 1, the array substrate 1 further includes a second conductive layer 15, and the second conductive layer 15 includes a plurality of second signal lines 151, and the second signal lines 151 intersect the first direction Y.

[0083] In some embodiments, in combination with Figure 2 and Figure 3 As shown in FIG. 1, the display panel 100 further includes an opposite substrate 2 and a liquid crystal layer 3, the opposite substrate 2 is arranged opposite to the array substrate 1, and the liquid crystal layer 3 is arranged between the array substrate 1 and the opposite substrate 2.

[0084] The opposite substrate 2 includes a second substrate 22 and a second light shielding layer 21, the second light shielding layer 21 is arranged on the second substrate 22, and the second light shielding layer 21 includes a plurality of second light shielding portions 211, and the orthographic projection of the second light shielding portions 211 on the first substrate 11 can not only cover the orthographic projection of at least part of the second signal lines 151 on the first substrate 11, but also cover the region between the two adjacent first metal sub-portions 131 in the first direction Y. In this way, the second signal lines 151 and part of the first signal lines 121 can be shielded by the second light shielding layer 21, so as to prevent the second signal lines 151 and the first signal lines 121 from reflecting ambient light, and thus the reflectivity of the display panel can be further reduced.

[0085] In some embodiments, the material of the second light shielding layer 21 includes resin, and the second light shielding layer 21 can be regarded as a black matrix.

[0086] In some embodiments, the first signal line 121 is one of a data line Data and a scan line Scan, and the second signal line 151 is the other of the data line Data and the scan line Scan.

[0087] In some embodiments, in combination with Figure 2 and 3As shown, the first signal line 121 is a data line Data, and the second signal line 151 is a scan line Scan, that is, the first conductive layer 12 is a source-drain electrode layer, and the second conductive layer 15 is a gate electrode layer.

[0088] In some embodiments, as shown in FIG. 1, the array substrate 1 includes, in sequence from the first substrate 11, a first gate electrode 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, and a first light shielding layer 13. The first electrode layer 104 includes a plurality of patterned pixel electrodes, and the second electrode layer 106 includes a common electrode. Figure 3

[0089] It should be noted that, Figure 3 Only the film layer structure of the first light shielding part 130 of the first light shielding layer 13 and the relative position relationship between the first light shielding part 130 and the data line Data in the thickness direction of the display panel are shown, and it does not represent the film layer position of the first light shielding layer 13 in actual application. In actual application, the first light shielding layer 13 can be disposed on the second electrode layer 106, the first light shielding layer 13 can also be disposed between the first electrode layer 104 and the second electrode layer 106, and the first light shielding layer 13 can also be disposed between the first electrode layer 104 and the color filter layer 14. In this way, the data line Data or the scan line Scan can also be shielded to reduce the reflectivity of the display panel, and the first metal sub-part 131 and the second metal sub-part 133 of the first light shielding part 130 can also be prevented from being offset, so that the reflectivity of the display panel can be further reduced, and the display effect of the display panel can be improved.

[0090] In other embodiments, the first signal line 121 can be a scan line Scan, and the second signal line 151 can be a data line Data. In this way, the same or similar technical effects as those of the above embodiments can also be achieved, and details are not described herein.

[0091] In some embodiments, the sum of the distance between two adjacent first metal sub-parts 131 in the first direction Y and the length of one of the first metal sub-parts 131 is a first distance D1, and the first distance D1 is equal to the center distance between two adjacent sub-pixels SP in the first direction Y. In this way, the overlapping part of the first metal sub-part 131 and the second metal sub-part 133 can cover the area between the two adjacent sub-pixels SP in the second direction X, so as to prevent color mixing of the two adjacent sub-pixels SP, and the extension direction of the scan line Scan is parallel to the second direction X.

[0092] In combination with Figure 2 ​As shown, the distance between two adjacent first metal sub-parts 131 in the first direction Y is a fourth distance D4, the length of the first metal sub-part 131 is a first length L1, the sum of the fourth distance D4 and the first length L1 is a first distance D1, the center distance between two adjacent sub-pixels SP in the first direction Y is a fifth distance D5, and the first distance D1 is equal to the fifth distance D5.

[0093] It should be noted that the center of the sub-pixel SP refers to the geometric center of the orthogonal projection of the sub-pixel SP on the first substrate 11, and the center distance between two sub-pixels SP refers to the distance between the centers of the two sub-pixels SP.

[0094] In some embodiments, the sum of the distance between two adjacent second metal sub-parts 133 in the second direction X and the width of one of the second metal sub-parts 133 is a second distance D2, and the second distance D2 is equal to the center distance between two adjacent sub-pixels SP in the second direction X. In this way, the overlapping part of the first metal sub-part 131 and the second metal sub-part 133 can cover the area where the first metal sub-part 131 and the second metal sub-part 133 overlap, which can cover the area between two adjacent sub-pixels SP in the second direction X, on the one hand, it can ensure that the area where the first metal sub-part 131 and the second metal sub-part 133 overlap can cover the data line Data, and on the other hand, it can prevent color mixing between two adjacent sub-pixels SP, thereby reducing the reflectivity of the display panel while improving the contrast of the display panel.

[0095] In combination with Figure 2 As shown, the distance between two adjacent first metal sub-parts 131 in the second direction X is a sixth distance D6, the width of the first metal sub-part 131 is a first width W1, the sum of the sixth distance D6 and the first width W1 is the second distance D2, the center distance between two adjacent sub-pixels SP in the second direction X is a seventh distance D7, and the second distance D2 is equal to the seventh distance D7.

[0096] In combination with Figure 3 , Figure 6 , Figure 7a to Figure 7d As shown, Figure 6 a flowchart of a manufacturing method of a display panel provided by an embodiment of the present application, Figure 7a a film layer diagram of a first metal part in a first display panel provided by an embodiment of the present application, Figure 7b a film layer diagram of a second metal sub-part in a first display panel provided by an embodiment of the present application, Figure 7c a superimposed layer diagram of a first metal part and a second metal sub-part in a first display panel provided by an embodiment of the present application, Figure 7dA stacked diagram of a first metal sub-part, an insulator part, and a second metal sub-part in a first type of display panel provided for embodiments of this application. The method for manufacturing the display panel includes the following steps:

[0097] Step S1: A first conductive layer 12 is formed on the first substrate 11, and a first insulating layer 102 is formed on the first conductive layer 12;

[0098] Step S2: A first metal film is formed on the first insulating layer 102, and the first metal film is patterned to form a plurality of spaced first metal parts 1310.

[0099] Step S3: An insulating film is formed on the first insulating layer 102 and the first metal part 1310, and a second metal film is formed on the insulating film.

[0100] Step S4: Pattern the second metal film to form a second metal sub-part 133; remove the insulating film not covered by the second metal sub-part 133 to form an insulator part 132; remove the first metal part not covered by the second metal sub-part 133 to form a first metal sub-part 131, and obtain a plurality of first light-shielding parts.

[0101] like Figure 7a As shown, the first metal part 1310 extends in the transverse direction and is continuously arranged, and a plurality of first metal parts 1310 are arranged at intervals in the longitudinal direction.

[0102] like Figure 7b As shown, the second metal sub-part 133 and the insulator part 132 completely overlap in the thickness direction of the display panel, the second metal sub-part 133 is continuously arranged in the longitudinal direction, and a plurality of second metal sub-parts 133 are spaced apart in the transverse direction.

[0103] In step S2, by etching the first metal film to form a plurality of first metal portions 1310, the area of ​​the metal material on the first substrate can be reduced to prevent the first substrate and the target material from being damaged by arc discharge caused by a large area of ​​metal during the deposition of insulating material in step S3.

[0104] Combination Figure 7c and Figure 7dAs shown, the second metal sub-section 133 is arranged crossing the first metal section 1310 and partially overlaps the first metal section 1310. During etching to form the second metal sub-section 133 and the insulating sub-section 132, the first metal section 1310 not covered by the second metal sub-section 133 and the insulating sub-section 132 can be etched at the same time to form a plurality of first metal sub-sections 131 arranged at intervals in the lateral direction and the longitudinal direction. In this way, the orthographic projection of the first metal sub-section 131 on the first substrate can be completely covered by the orthographic projection of the second metal sub-section 133 on the first substrate, so as to avoid the relative position of the first metal sub-section 131 and the second metal sub-section 133 from being deviated, thereby further reducing the reflectivity of the display panel and improving the display effect of the display panel.

[0105] In combination Figure 8 and Figure 9 As shown, Figure 8 a third display panel provided by an embodiment of the present application, Figure 9 a third display panel provided by an embodiment of the present application, Figure 8 As shown, Figure 8 and Figure 9 As shown, the structure of the third display panel is substantially the same as that of the first display panel, except that the first light shielding section 130 includes a plurality of first metal sub-sections 131, a plurality of insulating sub-sections 132, and a plurality of second metal sub-sections 133. Figure 2 to Figure 4 As shown,

[0106] and Figure 8 and Figure 9 As shown, the first metal sub-section 131, the insulating sub-section 132, and the second metal sub-section 133 all have a block structure, and the plurality of first metal sub-sections 131, the plurality of insulating sub-sections 132, and the plurality of second metal sub-sections 133 are arranged at intervals along the first direction Y to form a first light shielding section 130 in the shape of a broken line extending along the first signal line 121. In this way, the first light shielding section 130 in the shape of a broken line can be used to shield the first signal line 121 to avoid the first signal line 121 from reflecting ambient light, thereby reducing the reflectivity of the display panel.

[0107] In some embodiments, the orthographic projection of the second metal sub-section 133 on the first substrate 11 partially overlaps the orthographic projection of the first metal sub-section 131 on the first substrate 11. By making the size of the second metal sub-section 133 greater than the size of the first metal sub-section 131, the orthographic projection of the second metal sub-section 133 on the first substrate 11 can partially overlap the orthographic projection of the first metal sub-section 131 on the first substrate 11. In this way, the probability of the relative position of the first metal sub-section 131 and the second metal sub-section 133 being deviated due to process precision can be reduced, thereby further improving the production yield of the display panel.

[0108] In some embodiments, the length of the second metal sub-part 133 in the first direction Y is greater than the length of the first metal sub-part 131 in the first direction Y, and the end of the second metal sub-part 133 protrudes beyond the end of the first metal sub-part 131. This ensures that the orthographic projection of the second metal sub-part 133 on the first substrate 11 partially overlaps with the orthographic projection of the first metal sub-part 131 on the first substrate 11, thereby reducing the probability of the relative positions of the first metal sub-part 131 and the second metal sub-part 133 shifting due to process precision reasons, and thus further improving the production yield of the display panel.

[0109] In some embodiments, combined with Figure 8 and Figure 9 As shown, the orthographic projection of the second metal sub-part 133 on the first substrate 11 completely overlaps with the orthographic projection of the first metal sub-part 131 on the first substrate 11, that is, the length of the second metal sub-part 133 in the first direction Y is equal to the length of the first metal sub-part 131 in the first direction Y.

[0110] In some embodiments, combined with Figure 8 and Figure 9 As shown, each first light-shielding part 130 includes a plurality of first metal sub-parts 131, a plurality of insulator parts 132 and a plurality of second metal sub-parts 133. In the same first light-shielding part 130, any two adjacent insulator parts 132 in the first direction Y are spaced apart from each other.

[0111] In some embodiments, each first light-shielding portion 130 includes a plurality of first metal sub-portions 131, a plurality of insulator portions 132 and a plurality of second metal sub-portions 133. In the same first light-shielding portion 130, two adjacent insulator portions 132 in the first direction Y are continuously arranged, and the plurality of insulator portions 132 are sequentially connected to form an elongated insulating portion extending along the first direction Y.

[0112] In some embodiments, combined with Figure 8 and Figure 9 As shown, the first signal line 121 includes a data line. A groove 142 is provided between two adjacent filter portions 141 in the first direction Y. The groove 142 is located between two adjacent first light-shielding portions 130 in the first direction Y. The first metal sub-part 131 and the second metal sub-part 133 of the first light-shielding portion 130 are not disposed in the groove 142. By disconnecting the first light-shielding portion 130 at the groove 142, the first metal sub-part 131 and the second metal sub-part 133 can be prevented from forming a film in the groove 142. This prevents the poor film formation quality of the first metal sub-part 131 and the second metal sub-part 133 from causing short circuits in adjacent conductive film layers, thereby improving the production yield of the display panel.

[0113] In some embodiments, combined with Figure 8and Figure 9 As shown in FIG. 1, the opposite 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, the second light shielding layer 21 includes a plurality of second light shielding portions 211, the orthographic projection of the second light shielding portions 211 on the first substrate 11 can not only cover the orthographic projection of at least part of the scan lines Scan on the first substrate 11, but also cover the region between the adjacent two first light shielding portions 130 in the first direction Y, so as to prevent the data lines Data located in the region between the adjacent two first light shielding portions 130 from reflecting ambient light, thereby reducing the reflectivity of the display panel.

[0114] In combination with Figure 10a to Figure 10c As shown in FIG. 1, Figure 10a A film layer diagram of the insulating sub-portion and the second metal sub-portion in the third display panel provided by the embodiments of the present application, Figure 10b A stacking diagram of the first metal portion and the insulating sub-portion and the second metal sub-portion in the third display panel provided by the embodiments of the present application, Figure 10c A stacking diagram of the first metal sub-portion, the insulating sub-portion and the second metal sub-portion in the third display panel provided by the embodiments of the present application, the manufacturing method of the third display panel provided by the embodiments of the present application is substantially the same as the steps of the manufacturing method of the first display panel provided by the above-mentioned embodiments, the difference lies in that: after the patterning treatment of the second metal thin film and the insulating thin film in step S4, the plurality of second metal sub-portions 133 and the plurality of insulating sub-portions 132 formed are all in block structure, the plurality of second metal sub-portions 133 are arranged in the same column in the longitudinal direction and are spaced apart, so as to form a dashed line-shaped light shielding structure in the longitudinal direction.

[0115] In combination with Figure 10b As shown in FIG. 1, Figure 10c As shown in FIG. 1, the first metal portion 1310 extends and is continuously disposed in the transverse direction, the plurality of first metal portions 1310 are arranged in the longitudinal direction and are spaced apart, and the second metal sub-portion 133 partially overlaps the first metal portion 1310. In the process of etching to form the second metal sub-portion 133 and the insulating sub-portion 132, the first metal portion 1310 which is not covered by the second metal sub-portion 133 and the insulating sub-portion 132 can be etched at the same time to form a plurality of first metal sub-portions 131 which are spaced apart in the transverse direction and the longitudinal direction, so that the orthographic projection of the first metal sub-portion 131 on the first substrate can be completely covered by the orthographic projection of the second metal sub-portion 133 on the first substrate, so as to avoid the relative position of the first metal sub-portion 131 and the second metal sub-portion 133 from being deviated, thereby further reducing the reflectivity of the display panel and improving the display effect of the display panel.

[0116] According to the display panel provided by the above-mentioned embodiments of the present application, the embodiments of the present application further provide a display device, please refer to Figure 11 , Figure 11A schematic diagram of a display device provided by an embodiment of the present application is shown in FIG. 1.

The first light shielding layer includes a first light shielding portion, and the first light shielding portion includes a first metal sub-portion, an insulating sub-portion, and a second metal sub-portion which are sequentially stacked. A plurality of first metal portions are formed by performing a patterning process on the first metal film first, so as to reduce the area of the metal material on the first substrate. Then, the insulating film and the second metal film are sequentially formed on the first metal portion. In this way, the situation that the first substrate and the target material are damaged due to the arc discharge caused by the large-area metal during the film formation of the insulating material can be avoided. The second metal sub-portion is formed by performing a patterning process on the second metal film, and the insulating film and the first metal portion which are not covered by the second metal sub-portion are removed, so as to form the insulating sub-portion and the first metal sub-portion. In this way, the orthographic projection of the first metal sub-portion on the first substrate is located within the orthographic projection of the second metal sub-portion on the first substrate, and the relative position of the first metal sub-portion and the second metal sub-portion is prevented from being deviated. Therefore, the light shielding effect of the first light shielding layer can be improved, the reflectivity of the display panel can be reduced, and the display effect of the display panel can be improved.
