Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] In the display panel, the adhesion between the alignment film material (Polyimide, PI) and the sealant (Sealant) is poor, and it is easy to separate and cause leakage in a high temperature and high humidity environment. Patterned spacer bars (PS Bars) can be set at the boundaries of the display area to prevent the flow of the alignment film material, thereby preventing the alignment film in the peripheral area from overlapping with the sealant.

[0003] However, since there is no alignment film in the peripheral area, when the screen is completely black (L0), the liquid crystal in the peripheral area cannot be aligned by the alignment film and becomes disordered, thereby causing the black matrix (BM) light leakage phenomenon. Summary of the invention

[0033] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments provided by the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present application.

[0040] An embodiment of the present application provides a display panel, Figure 1 A structural diagram of a display panel provided in an embodiment of the present application; Figure 2 for Figure 1 A partial enlarged view of the display panel at position P; Figure 3 for Figure 2 A cross-sectional view of the display panel along section line AA'.

[0041] See also Figure 1 The display panel 1 includes a display area (Active Area, AA) 2 and a peripheral area 3 surrounding the display area 2 .

[0042] See also Figure 2 and Figure 3 The display panel 1 includes an array substrate 10 , a color filter substrate 11 and a liquid crystal layer 12 .

[0043] The array substrate 10 includes a first substrate 101 , and a planarization layer (PLN) 102 and a first alignment film 103 stacked in sequence on the first substrate 101 . The planarization layer 102 and the first alignment film 103 are arranged on a side of the first substrate 101 close to the color filter substrate 11 .

[0044] The color filter substrate 11 is arranged opposite to the array substrate 10, and the color filter substrate 11 includes a second substrate 111, and a black matrix (Black Matrix, BM) 112, multiple color resistance layers 113, an organic material layer 114, a second alignment film 13 and a spacer 15 stacked in sequence on the second substrate 111. The second alignment film 13 extends from the display area 2 to the peripheral area 3, and the second alignment film 13 includes a first portion 131 located in the peripheral area 2.

[0045] The liquid crystal layer 12 is disposed between the array substrate 10 and the color filter substrate 11, and the liquid crystal layer 12 extends from the display area 2 to the peripheral area 3. The liquid crystal layer 12 includes a second portion 121 located in the peripheral area 3, and the orthographic projection of the first portion 131 of the second alignment film 13 on the array substrate 10 covers the orthographic projection of the second portion 121 on the array substrate 10.

[0046] The display panel 1 provided in the embodiment of the present application includes an array substrate 10, a color filter substrate 11 and a liquid crystal layer 12. The second alignment film 13 in the color filter substrate 11 extends from the display area 2 to the peripheral area 3, and the liquid crystal layer 12 extends from the display area 2 to the peripheral area 3. The orthographic projection of the first portion 131 of the second alignment film 13 located in the peripheral area 3 on the array substrate 10 covers the orthographic projection of the second portion 121 of the liquid crystal layer 12 located in the peripheral area 3 on the array substrate 10, that is, the second portion 121 is fully covered by the first portion 131, so that the anchoring alignment of the liquid crystal in the peripheral area 3 can be achieved.

[0047] When the L0 screen is displayed, the liquid crystals of the second portion 121 are all in a closed state under the anchoring arrangement of the first portion 131 , and the light incident from the array substrate 10 side is completely blocked by the liquid crystal layer 12 , thereby improving the BM light leakage problem in the peripheral area 3 .

[0048] In some embodiments, see Figure 2 and Figure 3 The display panel 1 also includes a sealing glue layer 14 arranged in the peripheral area 3. The sealing glue layer 14 is located between the array substrate 10 and the color filter substrate 11. The sealing glue layer 14 is used to bond the array substrate 10 and the color filter substrate 11 together to form a packaging box body, which is used to accommodate liquid crystal.

[0049] In the array substrate 10, a first groove 100 is provided in the planarization layer 102, and the first groove 100 is located in the peripheral area 3. In the process of coating the alignment film material to form the first alignment film 103, the alignment film material flows into the first groove 100, which can prevent the alignment film material from flowing to the area where the frame sealant is set, and avoid the first alignment film 103 being located between the frame sealant layer 14 and the planarization layer 102, so that the frame sealant layer 14 can be in direct contact with the planarization layer 102. Since the frame sealant has good adhesion to the material of the planarization layer 102, the adhesion between the frame sealant layer 14 and the array substrate 10 is improved.

[0050] In the color filter substrate 11, the orthographic projection of the second alignment film 13 on the array substrate 10 does not overlap with the orthographic projection of the frame glue layer 14 on the array substrate 10. Since the adhesion between the frame glue and the material of the second alignment film 13 is poor, while the adhesion between the frame glue and the material of the organic material layer 114 is good, by arranging the second alignment film 13 and the frame glue layer 14 not to overlap, the second alignment film 13 can be avoided from being located between the color filter substrate 11 and the frame glue layer 14, thereby improving the adhesion between the color filter substrate 11 and the frame glue layer 14.

[0051] It can be understood that, along the direction X, the outer boundary M of the orthographic projection of the second alignment film 13 on the array substrate 10 coincides with the inner boundary N of the orthographic projection of the frame glue layer 14 on the array substrate 10, or the outer boundary M of the orthographic projection of the second alignment film 13 on the array substrate 10 is located inside the inner boundary N of the orthographic projection of the frame glue layer 14 on the array substrate 10. In both of the above cases, the anchoring alignment of the liquid crystal layer 12 in the peripheral area 3 is achieved while ensuring the adhesion of the frame glue layer 14, thereby improving the BM light leakage problem of the display panel 1 under the L0 screen.

[0052] For example, the embodiment provided in the present application is described by taking the outer boundary M of the orthographic projection of the second alignment film 13 on the array substrate 10 and the inner boundary N of the orthographic projection of the sealing glue layer 14 on the array substrate 10 as an example. Figure 2 When the display panel 1 is in the L0 screen, due to the alignment effect of the second alignment film 13 and the first alignment film 103, the liquid crystal layer 12 in the peripheral area 3 is in a closed state, and the light incident from the array substrate 10 side is blocked by the liquid crystal layer 12, thereby improving the BM light leakage problem in the peripheral area 3.

[0053] In some embodiments, see Figure 2 and Figure 3 In the color film substrate 11, the black matrix 112 includes a second groove 110 located in the peripheral area 3. The present application does not limit the cross-sectional shape of the second groove 110. For example, the cross-sectional shape of the second groove 110 can be U-shaped, rectangular or V-shaped. Along the direction Z, the second groove 110 can penetrate the black matrix 112 or not. The embodiment provided in the present application takes the second groove 110 as a rectangular shape penetrating the black matrix 112 as an example for explanation. The second groove 110 penetrating the black matrix 112 can disconnect the black matrix 112, preventing external static electricity from being transmitted from the peripheral area 3 to the inside of the display area 2 along the black matrix 112, thereby improving the anti-static (ESD) capability of the display panel 1.

[0054] The second groove 110 includes an outer edge E away from the display area 2, and the orthographic projection of the outer edge E of the second groove 110 on the second substrate 111 coincides with the inner boundary N of the orthographic projection of the frame glue layer 14 on the second substrate 111, that is, the position of the second groove 110 is set at the inner side boundary of the frame glue layer 14. In the process of forming the organic material layer 114 above the second groove 110, the organic material will flow into the second groove 110, and in the organic material layer 114 formed after curing, a depression will be formed at the position of the organic material layer 114 corresponding to the second groove 110, thereby generating a groove 120 located in the peripheral area 3.

[0055] The orthographic projection of the groove 120 on the second substrate 111 at least partially overlaps with the orthographic projection of the second groove 110 on the second substrate 111, that is, the positions of the groove 120 and the second groove 110 roughly correspond, and at least part of the groove 120 of the organic material layer 114 is located within the inner boundary N of the frame adhesive layer 14. Since the material polyimide (PI) of the second alignment film 13 has fluidity, during the process of forming the second alignment film 13 on the entire surface, PI will flow into the groove 120, thereby achieving the blocking of PI by the groove 120 and preventing PI from overlapping with the frame adhesive.

[0056] In the embodiment of the present application, the second alignment film 13 may fill the groove 120 and adhere to the side of the sealant layer 14 close to the display area 2, or the outer boundary M of the second alignment film 13 may be located in the groove 120 and not adhere to the sealant layer 14. When the display panel 1 is in the L0 screen, the above two situations are both possible. The liquid crystal layer 12 in the peripheral area 3 is in a closed state under the anchoring alignment of the alignment film, thereby improving the BM light leakage problem in the peripheral area 3. Figure 2 and Figure 3 The second alignment film 13 fills the groove 120 and is bonded to the side of the sealant layer 14 close to the display area 2 . In this case, the outer boundary M of the second alignment film 13 coincides with the inner boundary N of the sealant layer 14 .

[0057] In some embodiments, see Figure 3 Along the direction perpendicular to the second substrate 111 (direction Z), the OC glue located above the black matrix 112 has a certain flatness. When the depth of the second groove 110 is constant, the second groove 110 can be widened to make a groove 120 appear in the organic material layer 114, so as to achieve the effect of blocking the diffusion of PI liquid.

[0058] For example, as shown in Table 1 below, when the depth (THK) of the second groove 110 of the black matrix 112 is 1.2 μm, the width of the second groove 110 is greater than or equal to 17 μm, and the OC located above the second groove 110 is not smoothed, and an OC groove can be formed, so that part of the second alignment film 13 is located in the OC groove. As the width of the second groove 110 increases, the depth of the groove formed by the organic material layer 114 located above the second groove 110 also increases.

[0059]

[0060]

[0061] Table 1

[0062] Alternatively, as shown in Table 2 below, when the depth (THK) of the second groove 110 of the black matrix 112 is 1.3 μm, the width of the second groove 110 is greater than or equal to 14 μm, and the OC located above the second groove 110 is not smoothed, and an OC groove can be formed, so that part of the second alignment film 13 is located in the OC groove. As the width of the second groove 110 increases, the depth of the groove formed by the organic material layer 114 located above the second groove 110 also increases.

[0063]

[0064]

[0065] Table 2

[0066] Alternatively, as shown in Table 3 below, when the depth (THK) of the second groove 110 of the black matrix 112 is 1.4 μm, the width of the second groove 110 is greater than or equal to 11 μm, and the OC located above the second groove 110 is not smoothed, and an OC groove can be formed, so that part of the second alignment film 13 is located in the OC groove. As the width of the second groove 110 increases, the depth of the groove formed by the organic material layer 114 located above the second groove 110 also increases.

[0067]

[0068]

[0069] Table 3

[0070] It can be seen from the data in the above table that as the depth (THK) of the second trench 110 in the BM increases, the width of the second trench 110 required for the OC groove to appear gradually decreases.

[0072] See also Figure 4 The display panel 1 includes a display area 2 and a peripheral area 3 surrounding the outside of the display area 2. The display panel 1 includes an array substrate 10, a color filter substrate 11 and a liquid crystal layer 12. The array substrate 10 includes a first substrate 101, and a planarization layer 102 and a first alignment film 103 stacked in sequence on the first substrate 101. The planarization layer 102 and the first alignment film 103 are arranged on a side of the first substrate 101 close to the color filter substrate 11.

[0073] In some embodiments, see Figure 5 and Figure 6 The color filter substrate 11 is arranged opposite to the array substrate 10, and the color filter substrate 11 includes a second substrate 111, and a black matrix 112, an organic material layer 113, and a second alignment film 13 stacked in sequence on the second substrate 111 near the array substrate 10. The display panel 1 also includes a sealant layer 14 and a barrier layer 4 arranged in the peripheral area 3, wherein the material of the sealant layer 14 has a high adhesion to the material of the barrier layer 4.

[0074] The sealant layer 14 is located between the array substrate 10 and the color filter substrate 11, and the barrier layer 4 is located between the sealant layer 14 and the color filter substrate 11. The second alignment film 13 includes a first side surface H, and the barrier layer 4 includes a second side surface I close to the display area 2. The first side surface H is at least partially in contact with the second side surface I, that is, the second alignment film 13 is blocked by the barrier layer 4, so that the second alignment film 13 does not contact the sealant layer 14, which not only improves the adhesion between the sealant layer 14 and the color filter substrate 11, but also enables the second alignment film 13 to cover the liquid crystal layer 12 in the peripheral area 3, thereby achieving the effect of anchoring the alignment of the liquid crystal in the peripheral area 3, thereby improving the BM light leakage problem in the peripheral area 3.

[0075] In some embodiments, see Figure 5 and Figure 6, the second alignment film 13 includes a first surface 131 away from the second substrate 111, and the barrier layer 4 includes a second surface 42 away from the second substrate 111. Compared with the second substrate 111, the height of the second surface 42 is greater than or equal to the height of the first surface 131, that is, along the direction Z, the thickness of the barrier layer 4 is greater than or equal to the thickness of the second alignment film 13, so that in the process of forming the second alignment film 13, PI is blocked from flowing to the position where the sealing glue layer 14 is subsequently set, and the peripheral area 3 is covered by the second alignment film 13, so as to achieve anchoring alignment of the liquid crystal located in the peripheral area 3, thereby improving the BM light leakage problem in the peripheral area 3.

[0076] In some embodiments, see Figure 6 The color film substrate 11 also includes a spacer 15 arranged on the side of the organic material layer 114 away from the second substrate 111. The barrier layer 4 is made of the same material as the spacer 15 and is arranged in the same layer, that is, the barrier layer 4 is also set to PS. PS has good adhesion to the frame sealing glue, thereby improving the bonding strength between the frame sealing glue layer 14 and the color film substrate 11 and avoiding delamination.

[0077] Exemplarily, silicon balls are provided in the sealant layer 14, and the silicon balls are used to adjust the thickness and uniformity of the sealant layer 14. In the case where the barrier layer 4 is PS, since the surface of the PS is not necessarily flat during the formation of the entire surface of the PS, the diameter of the silicon balls in the sealant layer 14 can be reduced to increase the adjustable margin of the height of the sealant layer 14, thereby improving the consistency of the gap (Gap) between the display area 2 and the peripheral area 3, improving the problem of yellowing of the display panel caused by a high Gap, and thus improving the uniformity of the display.

[0078] Figure 7 is a partial enlarged view of another display panel at Q; Figure 8 for Figure 7 A cross-sectional view of the display panel along section line CC'; Fig. 9 Figure 8 Top view of the barrier layer in FIG.

[0079] For example, see Figure 7 to Figure 9 The barrier layer 4 includes a plurality of sub-barrier layers 41. Along the direction (direction X) from the display area 2 to the peripheral area 3, the plurality of sub-barrier layers 41 are arranged at intervals. The projections of the plurality of sub-barrier layers 41 on the first substrate 111 do not overlap. It can be understood that the barrier layer 4 has a plurality of island structures. The plurality of sub-barrier layers 41 can be arranged at equal intervals or unequal intervals, and the spacing distance between the plurality of sub-barrier layers 41 is greater than or equal to 5 μm to ensure the feasibility of the process.

[0080] In the embodiment provided in the present application, multiple sub-barrier layers 41 are arranged at equal intervals as an example for explanation. At least part of the sealant layer 14 is embedded between two adjacent sub-barrier layers 41, and the total contact area between the sealant layer 14 and the barrier layer 4 and the organic material layer 114 is increased, thereby improving the adhesion between the sealant layer 14 and the barrier layer 4 and the organic material layer 114, thereby improving the drop resistance of the display panel 1, as well as its high temperature and high humidity reliability and water resistance.

[0082] In some embodiments, see Fig.10 and Fig.11 The black matrix 112 includes a plurality of openings 115 located in the display area 2, and the color filter substrate 11 also includes a plurality of color resist layers 113, one color resist layer 113 is disposed in one opening 115, and the color of the color resist layer 113 can be one of red, green, and blue (Red, Green, Blue, R, G, B). The blocking layer 4 is made of the same material as the color resist layer 113, that is, the blocking layer 4 is set as the color resist layer 113, and an opening is added to the mask plate (Mask) used when forming the color resist layer 113 to form the blocking layer 4, and there is no need to add a separate Mask.

[0083] Exemplarily, the blocking layer 4 includes at least one color resist layer 113 . The embodiment provided in the present application is described by taking the blocking layer 4 including three color resist layers 113 of R, G, and B as an example.

[0084] In another aspect, a display device is provided. Fig.12 A structural diagram of a display device provided in an embodiment of the present application, such as Fig.12 As shown, the display device 5 includes a display panel 1 and a backlight module 51 as in any of the above embodiments.
