[0043] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0044] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. As used in this application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0045] It should be understood that although the terms first, second, third, etc. may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0046] To reduce production costs during the display substrate manufacturing process, reticles from large-sized substrates can be used to prepare reticles for smaller substrates. For example, the ratio of the long side to the short side of the large-sized substrate can be 16:9, while the ratio of the long side to the short side of the smaller substrate can be 32:9. During the manufacturing of the smaller substrate, a baffle can be used to partially shield the reticles from the larger substrate. However, the limited movement of the baffle means that portions of the peripheral areas of the resulting display substrate cannot be covered by the light-shielding layer, resulting in a shiny appearance in the peripheral areas of the display substrate.

[0047] The embodiments of the present application provide a display substrate and a display device that can solve the above-mentioned technical problems. The display substrate and the display device in the embodiments of the present application are described in detail below with reference to the accompanying drawings. The features of the following embodiments can complement or be combined with each other unless they conflict.

[0048] An embodiment of the present application provides a display substrate. As shown in FIG1 , the display substrate includes a display area 101 and a first peripheral area 102 located on at least one side of the display area 101 .

[0049] As shown in Figures 2 and 3 , the display substrate includes a first substrate 110 and a second substrate 120 disposed opposite each other. The first substrate 110 includes a first substrate 30 and a driving circuit layer 40 located on the side of the first substrate 30 facing the second substrate 120. The second substrate 120 includes a second substrate 60, a first light-shielding layer 10 located on one side of the second substrate 60, and a second light-shielding layer 20 located on the other side of the first light-shielding layer 10. As shown in Figures 4 and 5 , the first light-shielding layer 10 includes a first light-shielding portion 11 located in the display area 101 and the first peripheral area 102. The first light-shielding portion 11 has a plurality of first openings 111. The second light-shielding layer 20 is located in the first peripheral area 102 and includes a second light-shielding portion 21. A gap exists between the second light-shielding portion 21 and the third light-shielding portion 22. The orthographic projection of the second light-shielding portion 21 on the first substrate 30 overlaps with the orthographic projection of the first light-shielding portion 11 on the first substrate 30. The second light shielding portion 21 is not provided with any openings, that is, the second light shielding portion 21 is a continuous film layer.

[0050] In the display substrate provided by the embodiment of the present application, since the second substrate includes a first light-shielding layer and a second light-shielding layer, and the orthographic projection of the second light-shielding portion of the second light-shielding layer on the first substrate overlaps with the orthographic projection of the first light-shielding portion of the first light-shielding layer on the first substrate, the light emitted by the backlight source that passes through the portion opposite to the first light-shielding portion and the second light-shielding portion and then enters the second light-shielding layer can be absorbed by the second light-shielding layer, which helps to improve the problem of bright lines appearing in the first peripheral area of ​​the display substrate and enhance the user experience.

[0051] In the display substrate provided in the embodiment of the present application, the first light-shielding layer and the second light-shielding layer can be prepared using a mask plate of a display substrate larger than the display substrate, and different areas of the mask plate are used to prepare the first light-shielding portion and the second light-shielding portion.

[0052] In one embodiment, as shown in FIG1 , the display substrate further includes a second peripheral region 106 adjacent to the first peripheral region 102. The second peripheral region 106 includes a first sub-peripheral region 104 and a second sub-peripheral region 105. The first sub-peripheral region 104 and the second sub-peripheral region 105 are disposed opposite each other and located on opposite sides of the display region 101. The display substrate further includes a third peripheral region 103 disposed opposite the first peripheral region 102. The first and third peripheral regions 102 and 103 extend along a first direction X, while the first and second sub-peripheral regions 104 and 105 extend along a second direction Y. The first and second directions X and Y may be perpendicular to each other. The third peripheral region 103 may be equipped with fan-out circuits, flexible circuit boards, etc., while the first and second sub-peripheral regions 104 and 105 may be equipped with gate drive circuits. In some embodiments, the first direction X may be a row direction, and the second direction Y may be a column direction.

[0053] In one embodiment, as shown in FIG. 1 , the size of the display substrate in the first direction X is greater than the size of the display substrate in the second direction Y.

[0054] In one embodiment, as shown in Figures 2 and 3, the display substrate includes a liquid crystal layer 50, which is located between the first substrate 110 and the second substrate 120. The display substrate also includes a first electrode (not shown) and a second electrode (not shown). The display substrate may include a plurality of sub-pixels, and the plurality of sub-pixels may include a first sub-pixel located in the first peripheral area and a plurality of second sub-pixels located in the display area. Each sub-pixel includes a first electrode, a second electrode and liquid crystal molecules. One of the first electrode and the second electrode is a pixel electrode, and the other is a common electrode. Each first opening 111 of the first light-shielding layer 10 may correspond to a pixel electrode respectively, and in the film layer stacking direction of the display substrate, the first opening 111 is opposite to the corresponding pixel electrode and opposite to a partial area of ​​the common electrode.

[0055] In one embodiment, the driving circuit layer 40 includes a plurality of pixel circuits. The pixel circuits may correspond to sub-pixels one-to-one, and each pixel circuit drives the corresponding sub-pixel.

[0056] In one embodiment, as shown in Figures 2 and 3, the first light-shielding layer 10 is located on the side of the second substrate 60 facing the first base plate 110, and the second light-shielding layer 20 is located on the side of the first light-shielding layer 10 facing the first base plate 110. The second base plate 120 further includes a color filter layer, which is located on the side of the second light-shielding layer 20 facing away from the base substrate 60. The color filter layer includes a plurality of color filter portions, each of which has an orthographic projection on the second base plate 60 falling within the orthographic projection of a first opening 111 on the second base plate 60.

[0057] In one embodiment, as shown in FIG. 2 and FIG. 3 , the display substrate further includes a sealant 70 . The sealant 70 is located between the first substrate 110 and the second substrate 120 . The sealant 70 is located in the first peripheral region 102 and surrounds the liquid crystal layer 50 .

[0058] In one embodiment, as shown in Figures 2 and 3, the second substrate 120 further includes a first polarizer 91 located on the side of the second substrate 60 away from the first substrate 110, and the first substrate 110 further includes a second polarizer 92 located on the side of the first substrate 30 away from the second substrate 120.

[0059] In one embodiment, as shown in FIG. 4 and FIG. 5 , the second light shielding layer 20 further includes a third light shielding portion 22 located on a side of the second light shielding portion 21 away from the display area 101 . The third light shielding portion 22 defines a plurality of second openings 221 .

[0060] In one embodiment, the shape and area of ​​the first opening 111 of the first light shielding portion 11 are the same as those of the second opening 221 of the third light shielding portion 22 .

[0061] In one embodiment, as shown in FIG. 4 and FIG. 5 , in the direction from the display area 101 to the first peripheral area 102 , that is, in the second direction Y, the size of the third light shielding portion 22 is larger than that of the second light shielding portion 21 .

[0062] In one embodiment, in the second direction Y, the size of the third light shielding portion 22 may be 2.6 mm, the size of the second light shielding portion 21 may be 2.3 mm, and the gap between the second light shielding portion 21 and the third light shielding portion 22 may be 0.4 mm.

[0063] In one embodiment, the second light shielding portion 21 is in contact with the first light shielding layer 10. The first light shielding layer 10 and the second light shielding layer 21 can be formed by coating a light shielding material and then exposing the light shielding material twice. When the light shielding material is a negative photoresist, the first light shielding layer is exposed first, and the second light shielding layer is formed by exposing the material twice.

[0064] In one embodiment, as shown in FIG4 , the orthographic projection of the third light-shielding portion 22 on the first substrate 30 does not overlap with the orthographic projection of the first light-shielding layer 10 on the first substrate 30. This arrangement ensures that even if the third light-shielding portion 22 becomes charged due to ions in the air or static electricity generated by the edge of the display substrate, the charge cannot be transferred from the third light-shielding portion 22 to the first light-shielding portion 11. This prevents the first light-shielding portion 11 from becoming charged and causing the image displayed in the display area of ​​the display substrate to appear green, thereby improving the user experience.

[0065] 4 , the edge of the third light shielding portion 22 away from the display area 101 is flush with the edge of the first peripheral area 102 away from the display area 101. With this arrangement, when preparing the third light shielding portion 22, the preparation precision requirement for the third light shielding portion 22 is relatively low.

[0066] In another embodiment, as shown in FIG. 5 , the orthographic projection of the third light shielding portion 22 on the first substrate overlaps with a portion of the orthographic projection of the first light shielding portion 11 on the first substrate away from the display area 101 .

[0067] Furthermore, as shown in FIG5 , the edge of the first light shielding portion 11 away from the display area 101 is flush with the edge of the first substrate 30 on the same side, and the display substrate further includes an insulating portion 80 located outside the first light shielding portion 11. The outside of the first light shielding portion 11 refers to the side of the first light shielding portion 11 away from the display area 101. By providing the insulating portion 80, static electricity and ions in the air can be prevented from coming into contact with the third light shielding portion 22, thereby causing the third light shielding portion 22 to become charged. This can further prevent the first light shielding portion 11 from becoming charged and causing the image displayed in the display area of ​​the display substrate to appear green. In this embodiment, the first light shielding portion 11 can extend to near the edge of the first peripheral area 102 away from the display area 101. In this embodiment, the third light shielding portion 22 is in contact with the first light shielding portion 11.

[0068] Furthermore, as shown in FIG3 , the insulating portion 80 is located between the first polarizer 91 and the second polarizer 92. The edge of the insulating portion 80 away from the display area 101 may be flush with the edge of the first peripheral area 102 away from the display area 101. Placing the insulating portion 80 between the first polarizer 91 and the second polarizer 92 secures the insulating portion 80 and prevents it from falling off the display substrate. The transmission axis of the first polarizer 91 and the transmission axis of the second polarizer 92 may be perpendicular to each other. In this way, the light emitted by the backlight source that passes through the second polarizer 92 and the insulating portion 80 is absorbed by the first polarizer 91 after entering the first polarizer 91, thereby preventing the first peripheral area 101 of the display substrate from appearing shiny. In this embodiment, the edge of the first polarizer 91 away from the display area 101 may extend beyond the second substrate 60, and the edge of the second polarizer 92 away from the display area 101 may extend beyond the first substrate 30.

[0069] In one embodiment, the orthographic projection of the first polarizer 91 on the first substrate 30 is located in the first peripheral area 102 and the edge extending along the first direction X coincides with the orthographic projection of the second polarizer 92 on the first substrate 30 is located in the first peripheral area 102 and the edge extending along the first direction X.

[0070] In one embodiment, the orthographic projection of the sealant 70 on the first substrate 30 entirely falls within the orthographic projection of the first polarizer 91 on the first substrate 30, and the orthographic projection of the sealant 70 on the first substrate 30 entirely falls within the orthographic projection of the second polarizer 92 on the first substrate 30. This arrangement prevents the first peripheral area 102 where the sealant 70 is located from being shiny.

[0071] In one embodiment, as shown in Figure 6, the frame sealing glue 70 is located in the first peripheral area 102 and away from the edge of the display area 101 on the inner side of the edge 911 of the first polarizer 91 on the same side, and the frame sealing glue 70 is located in the first peripheral area 102 and away from the edge of the display area 101 on the inner side of the edge 921 of the second polarizer 92 on the same side.

[0072] In one embodiment, as shown in FIG6 , the first polarizer 91 is located in the first peripheral region 102, and an edge 911 extending along the first direction X is located inside an edge 61 of the second substrate 60 located on the same side. The second polarizer 92 is located in the first peripheral region 102, and an edge 921 extending along the first direction X is located inside an edge 31 of the first substrate 30 located on the same side. For example, the distance between the edge 911 of the first polarizer 91 and the edge 61 of the second substrate 60 is 0.6 mm, and the distance between the edge 921 of the second polarizer 92 and the edge 31 of the first substrate 30 is 0.6 mm.

[0073] In one embodiment, the area of ​​the first peripheral area 102 that extends beyond the first polarizer 91 is not incident with light from the backlight source, or the surface of the first peripheral area 102 that extends beyond the first polarizer 91 and faces away from the second substrate 120 is covered by the housing of the display device where the display substrate is located. This prevents the area of ​​the first peripheral area 102 that extends beyond the first polarizer 91 from being illuminated.

[0074] In one embodiment, as shown in FIG6 , the first light shielding portion 11 is in contact with the second light shielding portion 21; the first light shielding portion 11 includes a light shielding portion 112 without the first opening 111, and the total transmittance of the light shielding portion 112 of the first light shielding portion 11 and the portion of the second light shielding portion 21 in contact with the light shielding portion 112 is less than the transmittance of the portion of the second light shielding portion 21 opposite the first opening 111. In some embodiments, the total thickness of the light shielding portion 112 of the first light shielding portion 11 and the portion of the second light shielding portion 21 in contact with the light shielding portion 112 is greater than the thickness of the portion of the second light shielding portion 21 opposite the first opening 111, thereby making the total transmittance of the light shielding portion 112 of the first light shielding portion 11 and the portion of the second light shielding portion 21 in contact with the light shielding portion 112 greater than the transmittance of the portion of the second light shielding portion 21 opposite the first opening 111.

[0075] In one embodiment, as shown in FIG7 , the first light-shielding layer 10 includes a fourth light-shielding portion 12 located in the second peripheral region 106 . The second light-shielding portion 21 is in direct contact with a portion of the fourth light-shielding portion 12. The orthographic projection of the fourth light-shielding portion 21 on the first substrate partially overlaps with the orthographic projection of the second light-shielding portion 21 on the substrate. A boundary line 108 exists between the area where the second light-shielding portion 21 and the fourth light-shielding portion 12 are in contact and the area where the fourth light-shielding portion 12 and the second light-shielding portion 21 are not in contact. The combined thickness of the area where the second light-shielding portion 21 and the fourth light-shielding portion 12 are in contact and the second light-shielding portion 21 is greater than the thickness of the area where the fourth light-shielding portion 12 and the second light-shielding portion 21 are not in contact. This creates a height difference between the area where the second light-shielding portion 21 and the fourth light-shielding portion 12 are in contact and the area where the fourth light-shielding portion 12 and the second light-shielding portion 21 are not in contact, thereby creating a boundary line 108 between the two areas. In some embodiments, the boundary line 108 may be a straight line. In some embodiments, the boundary line 108 extends along the first direction X.

[0076] In one embodiment, as shown in FIG6 , the orthographic projection of the first light shielding portion 11 on the first substrate does not overlap with the orthographic projection of the third light shielding portion 22 on the first substrate, and the edge of the third light shielding portion 22 away from the display area 22 may extend beyond the edge 911 of the first polarizer 91 on the same side, and extend beyond the edge 921 of the second polarizer 92 on the same side. In a display device where the display substrate is located, light emitted by the backlight source cannot be incident on the area where the third light shielding portion 22 is located, or light emitted by the backlight source cannot be incident on the area where the third light shielding portion 22 extends beyond the first polarizer, or the housing of the display device covers the area where the third light shielding portion 22 is located, and light emitted by the backlight source cannot be emitted after entering the area where the third light shielding portion 22 is opposite to the first polarizer and the second polarizer. In this way, the area where the third light shielding portion 22 is located can be illuminated.

[0077] In one embodiment, as shown in Figure 5, the orthographic projection of the first light shielding portion 11 on the first substrate overlaps the orthographic projection of the third light shielding portion 22 on the first substrate. The edge of the first light shielding portion 11 away from the display area 101 is flush with the edge of the first substrate 30 on the same side. In this case, the display substrate further includes an insulating portion located outside the first light shielding portion 11. The orthographic projection of the third light shielding portion 22 on the first substrate 30 is covered by the orthographic projection of the first polarizer 91 on the first substrate 30, and is also covered by the orthographic projection of the second polarizer 92 on the first substrate 30. With this arrangement, the transmission axes of the first polarizer 91 and the second polarizer 92 are perpendicular to each other. In a display device in which the display substrate is located, light emitted by a backlight source, when incident on the area of ​​the third light shielding portion 22, passes through the second polarizer 92, then passes through the second opening 221 of the third light shielding portion 22 and is incident on the first polarizer 91, where it is absorbed by the first polarizer 91. This prevents the first peripheral area 102 of the display substrate from being illuminated.

[0078] In one embodiment, the orthographic projection of the gap between the second light-shielding portion 21 and the third light-shielding portion 22 on the first substrate is covered by the orthographic projection of the first polarizer 91 on the first substrate 30, and is also covered by the orthographic projection of the second polarizer 92 on the first substrate 30. With this arrangement, the transmission axes of the first polarizer 91 and the second polarizer 92 are perpendicular to each other. Light incident from the side of the first substrate 110 away from the second substrate, after passing through the second polarizer 92, can pass through the gap to be incident on the first polarizer 91 and absorbed by the first polarizer 91. This prevents the gap between the second light-shielding portion 21 and the third light-shielding portion 22 from causing the first peripheral region 102 of the display substrate to appear bright.

[0079] In one embodiment, as shown in FIG4 , the portion of the first light shielding portion 11 located in the first peripheral area 102, away from the display area 101, is provided with a notch 113. The orthographic projection of the edge of the notch 113 adjacent to the display area 101 on the first substrate 30 is covered by the orthographic projection of the second light shielding portion 21 on the first substrate 30. During the preparation of the first light shielding layer, the tilting of the baffle can cause the notch 113 to form in the portion of the first light shielding portion 11 located in the first peripheral area 102. By ensuring that the orthographic projection of the edge of the notch 113 adjacent to the display area 101 on the first substrate 30 is covered by the orthographic projection of the second light shielding portion 21 on the first substrate 30, the area of ​​the first peripheral area 102 where the notch 113 is located can be prevented from shining. In the embodiment shown in FIG4 , the area adjacent to the notch 113 of the first light shielding portion 11 is partially covered by the second light shielding portion 21. In other embodiments, the area adjacent to the notch 113 of the first light shielding portion 11 can be entirely covered by the second light shielding portion 21.

[0080] In one embodiment, as shown in FIG4 , in the direction from the display area 101 to the first peripheral area 102, the portion of the first light shielding portion 11 where the notch portion 113 is provided gradually decreases in size in a direction perpendicular to the direction from the display area 101 to the first peripheral area 102 (i.e., the first direction X). That is, in the direction from the display area 101 to the first peripheral area 102, the size of the notch portion 113 in the first direction X gradually increases. FIG4 exaggerates the size of the notch portion 113 to better illustrate it. In an actual structure, the size of the notch portion 113 in the second direction Y is smaller than the size of the second light shielding portion 12 in the second direction Y. In some embodiments, the size of the notch portion 113 in the second direction Y may range from 0.756 to 1.002 mm.

[0081] In one embodiment, at least some liquid crystal molecules in the liquid crystal layer 50 located in the first peripheral area 102 are in contact with the frame sealant 70 ; the orthographic projection of the second light shielding portion 21 on the first substrate 30 covers the orthographic projection of at least some liquid crystal molecules on the first substrate 30 .

[0082] In the process of preparing the display substrate, a sealant 70 and one of the liquid crystal layer 50 are set on the first substrate 110, and a sealant 70 and the other of the liquid crystal layer 50 are set on the second substrate 120. Then, the first substrate 110 and the second substrate 120 are aligned so that the first substrate 110 and the second substrate 120 are bonded together by the sealant 70. Before the sealant is cured, some liquid crystal molecules are in contact with the sealant 70. During the curing process of the sealant 70, the liquid crystal molecules in contact with the sealant are fixed. Even if an electric field is applied to these liquid crystal molecules, they cannot be deflected. These liquid crystal molecules will cause bright lines to appear in the first peripheral area 102, affecting the user experience. By setting the orthographic projection of the second light shielding portion 21 on the first substrate 30 to cover the orthographic projection of at least part of the liquid crystal molecules on the first substrate 30, the problem of bright lines appearing in the first peripheral area 102 due to the liquid crystal molecules being fixed by the sealant 70 can be solved.

[0083] In one embodiment, the orthographic projection of the edge of the frame sealant 70 facing the display area 101 on the first substrate 30 is covered by the orthographic projection of the second light shielding portion 21 on the first substrate 30. This ensures that the orthographic projection of the second light shielding portion 21 on the first substrate 30 covers the orthographic projection of the liquid crystal molecules in contact with the frame sealant on the first substrate 30. In the embodiment shown in Figure 6, the area of ​​the orthographic projection of the frame sealant 70 on the first substrate 30 partially overlaps with the orthographic projection of the second light shielding portion 21 on the first substrate 30. In other embodiments, only the edge of the orthographic projection of the frame sealant 70 on the first substrate 30 facing the display area 101 overlaps with the orthographic projection of the second light shielding portion 21 on the first substrate 30.

[0084] In one embodiment, in the direction from the display area 101 toward the first peripheral area 102, that is, in the second direction Y, the size of the overlapping portion between the orthographic projection of the designed position of the frame sealant 70 on the first substrate 30 and the orthographic projection of the second light shielding portion 21 on the first substrate 30 is greater than or equal to the deviation of the edge position of the frame sealant 30 in the second direction Y. With this configuration, even if the deviation of the edge position of the frame sealant 30 in the second direction Y reaches a maximum during the preparation process, it is ensured that the orthographic projection of the frame sealant 70 on the first substrate 30 toward the edge of the display area overlaps with the orthographic projection of the second light shielding portion 21 on the first substrate 30.

[0085] In some embodiments, the width of the frame sealant 70 in the second direction Y is designed to be 1.8 mm, and the deviation between the two opposing edges of the frame sealant 70 is 0.215 mm, meaning the maximum width of the frame sealant can reach 2.23 mm. The display substrate provided in the embodiments of this application is manufactured using a mask for a large-scale display substrate. Large-scale display substrates require that the size of the second light shielding portion 21 in the second direction Y be greater than or equal to the size of the frame sealant 70. In the embodiments of this application, the size of the second light shielding portion 21 in the second direction Y can be approximately 2.3 mm.

[0086] In one embodiment, as shown in Figure 8, the orthographic projection of the sealing glue 70 on the first substrate 30 overlaps with the orthographic projection of the second light-shielding portion 21 on the first substrate 30, and the orthographic projection of the sealing glue 70 on the first substrate 30 overlaps with the orthographic projection of the third light-shielding portion 22 on the first substrate 30.

[0087] Further, as shown in Figure 8, in the direction from the display area 101 to the first peripheral area 102, that is, in the second direction Y, the size of the overlapping part of the orthographic projection of the frame sealing glue 70 on the first substrate 30 and the orthographic projection of the second shading portion 21 on the first substrate 30 is a first size d1, and the size of the overlapping part of the orthographic projection of the frame sealing glue 70 on the first substrate 30 and the orthographic projection of the third shading portion 22 on the first substrate 30 is a second size d2, and the first size d1 is smaller than the second size d2.

[0088] Furthermore, the second dimension d2 may be greater than one-third of the first dimension d1. The second dimension d2 may be substantially the same as the gap between the second light shielding portion 21 and the third light shielding portion 22 in the second direction Y. In some embodiments, the first dimension d2 is approximately 0.9 mm, and the second dimension d2 is approximately 0.4 mm.

[0089] In one embodiment, as shown in Figures 4 and 5, the portion of the first light-shielding portion 11 located in the first peripheral area includes a first sub-light-shielding portion 114 and a second sub-light-shielding portion 115 located between the first sub-light-shielding portion 114 and the display area 101, and the display substrate also includes multiple rows of first sub-pixels located in the first peripheral area 102; the orthographic projection of one of the first sub-pixels on the first substrate falls within the orthographic projection of a first opening of the second sub-light-shielding portion 115 on the first substrate 30; the orthographic projection of the second sub-light-shielding portion 115 on the first substrate 30 is at least partially outside the orthographic projection of the second light-shielding portion 21 on the first substrate 30; the first sub-pixel includes liquid crystal molecules, and the long axis direction of the liquid crystal molecules of the first sub-pixel is perpendicular to the surface of the first substrate 30. Because the long axis direction of the liquid crystal molecules in the first sub-pixel is perpendicular to the surface of the first substrate 30, light emitted by the backlight source located on the side of the first substrate facing away from the second substrate cannot pass through the first sub-pixel. In other words, the area where the second sub-light shielding portion 115 is located is in a dark state. This can prevent the second light shielding layer 20 from covering the display area 101 due to errors in the preparation of the second light shielding layer 20, thereby affecting the display effect of the display area 101. Moreover, even if the second light shielding portion covers the first sub-pixel, it will not affect the dark state effect presented in the first peripheral area. The preparation accuracy requirements for the second light shielding portion are low, which helps to reduce the difficulty of manufacturing the display substrate. In some embodiments, the long axis direction of the liquid crystal molecules in the first sub-pixel can be made perpendicular to the surface of the first substrate 30 by controlling the electrical signal output by the pixel circuit to the pixel electrode of the first sub-pixel. In some embodiments, each row of first sub-pixels includes multiple first sub-pixels arranged along the first direction X. The display substrate may include, for example, six rows of first sub-pixels.

[0090] Furthermore, as shown in Figure 4 , the edge of the orthographic projection of the second sub-light-shielding portion 115 on the first substrate 30 facing away from the display area 101 overlaps with the edge of the orthographic projection of the second light-shielding portion 21 on the first substrate 30 facing the display area 101. This configuration prevents the orthographic projection of the second sub-light-shielding portion 115 on the first substrate 30 from overlapping too much with the orthographic projection of the second light-shielding portion 21 on the first substrate 30, when the distance between the second light-shielding portion 21 and the third light-shielding portion 22 is constant, thereby preventing the orthographic projection of the second sub-light-shielding portion 115 on the first substrate 30 from overlapping too much, thereby causing the third light-shielding portion 22 to contact the first light-shielding portion 11, and thus causing the image displayed in the display area of ​​the display substrate to appear green. In some embodiments, the dimension of the second sub-light-shielding portion 115 in the second direction Y can be approximately 2.2 mm.

[0091] In one embodiment, the orthographic projection of the end portion of the signal line connected to the pixel circuit corresponding to the first sub-pixel on the first substrate 30 is covered by the orthographic projection of the second light shielding portion 21 on the first substrate 30. In this way, the second light shielding portion 31 can prevent the end portion of the signal line covered by it from reflecting light.

[0092] In one embodiment, the edge of the second light shielding portion 21 facing the display area 101 overlaps the edge of the display area 101 facing the first peripheral area 102. In this embodiment, the first peripheral area 102 may not be provided with first sub-pixels. This helps reduce the width of the first peripheral area 102 and increase the area of ​​the display area 101. In this embodiment, the second light shielding layer 20 requires high fabrication precision, and the second light shielding layer 20 does not cover the display area 101.

[0093] In one embodiment, as shown in FIG9 , the second light-shielding layer 20 is located on a side of the second substrate 60 facing away from the first base plate 110, and the first light-shielding layer 10 is located on a side of the second substrate 60 facing the first base plate 110. The second light-shielding layer 20 can be formed by coating a light-shielding material, for example, the second light-shielding layer 20 can be formed by spraying tungsten powder.

[0094] Furthermore, as shown in FIG. 9 , the second light shielding layer 20 is located between the first polarizer 91 and the second substrate 60 .

[0095] Furthermore, the thickness of the second light-shielding layer 20 is less than 1 / 10 of the thickness of the first light-shielding layer 10. The thickness of the second light-shielding layer 20 can be less than or equal to 10 μm, while the thickness of the first light-shielding layer 10 can be greater than 100 μm. The thickness of the adhesive layer between the first polarizer 91 and the second substrate 60 is approximately 200 μm. In this manner, the second light-shielding layer 20 does not affect the adhesion of the first polarizer 91 to the second substrate 60.

[0096] Furthermore, as shown in FIG. 10 , there is a gap between the edge of the second light shielding layer 20 facing the display area 101 and the display area 101 .

[0097] Furthermore, in the second direction Y, the width of the second light-shielding layer 20 may be greater than or equal to the sum of the maximum process error between the design position and the actual position of the edge of the frame sealant 70 and the size of the liquid crystal molecules in contact with the frame sealant 70. With this configuration, even if the process error of the frame sealant 70 reaches its maximum value, the frame sealant 70 can still cover the liquid crystal molecules in contact with the frame sealant 70, thereby preventing the liquid crystal molecules in contact with the frame sealant 70 from causing bright lines to appear in the first peripheral area 102. In some embodiments, in the second direction Y, the maximum process error between the design position and the actual position of the edge of the frame sealant 70 is 0.215 mm, the size of the liquid crystal molecules in contact with the frame sealant 70 is 18.6 μm, and the size of the second light-shielding layer 20 is greater than 0.44 mm.

[0098] In one embodiment, the driving circuit layer 40 includes a target signal line, and the shape and area of ​​the target signal line are the same as those of the second light shielding layer 20. In this configuration, the second light shielding layer 20 can be prepared using the same mask used to prepare the target signal line, which helps reduce preparation costs.

[0099] In one embodiment, the target signal line is a gate signal line for providing a gate driving signal to the pixel circuit. The second light shielding layer 20 can be formed by using a long strip opening in the edge region of the mask corresponding to the gate signal line.

[0100] Furthermore, in the second direction Y, the size of the second light-shielding layer 20 is greater than the distance between the edge of the first light-shielding portion 11 away from the display area 101 and the edge of the first peripheral area 102 away from the display area 101. This allows the orthographic projection of the second light-shielding layer 20 on the second substrate 60 to overlap with the orthographic projection of the first light-shielding portion 11 on the second substrate 60. In this embodiment, an insulating portion is required around the periphery of the second light-shielding layer 20 to prevent the display area from emitting a green tint. In some embodiments, the size of the second light-shielding layer 20 in the second direction Y is 10.7 mm.

[0101] In this embodiment, a boundary line exists between a region where the second light shielding layer contacts the fourth light shielding portion and a region where the fourth light shielding portion does not contact the second light shielding portion.

[0102] In another embodiment, the target signal line is a common voltage signal line or a ground signal line. The second light shielding layer 20 can be formed by using a long strip opening in the edge area of ​​the mask corresponding to the common voltage signal line and the ground signal line.

[0103] Furthermore, in the second direction Y, the size of the target signal line is smaller than the distance between the edge of the first light-shielding layer 20 away from the display area 101 and the edge of the first peripheral area 102 away from the display area 101. Thus, when the second light-shielding layer 20 is made with high precision, the orthographic projection of the second light-shielding layer 20 on the second substrate 60 and the orthographic projection of the first light-shielding portion 11 on the second substrate 60 do not overlap. In some embodiments, the size of the target signal line in the second direction Y can be 1.75 mm or 1.5 mm.

[0104] In this embodiment, a boundary line exists between a region where the second light shielding layer contacts the fourth light shielding portion and a region where the fourth light shielding portion does not contact the second light shielding layer.

[0105] Figure 11 is a schematic diagram of a partial structure of the second light-shielding layer 20. As shown in Figure 11, the boundary of the second light-shielding layer is partially curved and partially folded. The above-mentioned boundary line is a non-straight line. The boundary line portion 201 can be curved and the boundary line portion 202 can be folded.

[0106] The embodiment of the present application further provides a display device, which includes the above-mentioned display substrate.

[0107] In one embodiment, the display substrate further includes a backlight source, and the backlight source is located on a side of the first substrate facing away from the second substrate.

[0108] In some embodiments, the display device further includes a housing, and the display substrate is embedded in the housing.

[0109] The display device provided in the embodiments of the present application may be any appropriate display device, including but not limited to mobile phones, tablet computers, televisions, monitors, laptop computers, digital photo frames, navigators, e-books, and any other products or components with display functions.
