[0045] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and accompanying drawings. Similar components in the accompanying drawings are represented by the same or similar reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0046] It should be noted that the terms “having”, “including”, “comprising”, etc. described in the present invention are all open-ended meanings, that is, when describing that a module “has”, “including” or “comprising” the first element, the second element and / or the third element, it means that the module includes other elements in addition to the first element, the second element and / or the third element. In addition, the ordinal numbers such as “first”, “second” and “third” in the present invention are not intended to limit the specific order, but are only used to distinguish the various parts. In addition, the “same-layer arrangement” described in the present invention refers to the arrangement using the same material with the same process; the “forming B on component A” described in the present invention can mean that B is directly formed on component A, or it can mean that other components or layers are included between components A and B.

[0047] In the prior art, the color resist layer in the display area is provided with columnar spacers at intervals so as not to affect the light emission. The columnar spacers naturally do not affect the fluidity of the liquid crystal, and the upper and lower substrates are directly in contact and supported when the box is assembled. Since the non-display area does not emit light, the surrounding area simply adopts an integrated PS Wall design. Therefore, in the non-display area, in order to ensure the support of the upper and lower substrates of the LCD screen and take into account the fluidity of the liquid crystal, the PS Wall is grown on the upper substrate and a gap is left between the PS Wall and the lower substrate. However, this design leads to weak support in the non-display area, which is particularly serious on the side of the full screen with wide edges.

[0048] Reference Figure 1As shown, due to the large gap in the non-display area, when the non-display area is deformed due to contact, the periphery is weakly supported and deformed, and the thickness of the non-display area changes, causing the liquid crystal in the non-display area to flow to the display area; the deformation of the glass in the pressing area also causes the glass in the display area to tilt, so that the photoelastic effect of the glass deformation stress and the difference in the thickness of the liquid crystal box work together to cause the liquid crystal to be unevenly distributed in the part of the display area close to the non-display area. Because the LCD screen displays the picture under the action of liquid crystal and polarizer, the uneven distribution of liquid crystal leads to regional optical brightness differences, resulting in light leakage around the display area, reducing the display effect of the display panel.

[0049] To solve one of the above problems, a first aspect of the present invention provides a display panel, including a display area and a non-display area, wherein the display panel includes a first substrate, a second substrate, and a liquid crystal layer disposed between the first substrate and the second substrate, and the display panel further includes at least one dielectric stacking portion disposed on the non-display area, wherein

[0050] The second substrate comprises a spacer wall with a plurality of openings arranged corresponding to the medium stacking portion, and the spacer wall and the medium stacking portion are used to form support when the second substrate is boxed with the first substrate.

[0051] In this embodiment, by providing a non-display area of ​​at least one dielectric stack portion and providing a partition wall with multiple openings arranged corresponding to the dielectric stack portion, the first substrate and the second substrate can provide good support for the non-display area of ​​the display panel through the dielectric stack portion and the partition wall when the first substrate and the second substrate are assembled, while not affecting the fluidity of the liquid crystal, avoiding light leakage around the display area of ​​the display panel, and improving the display uniformity of the display panel. The manufacturing process is simple and easy to implement, and has broad application prospects.

[0052] In a specific example, referring to Figure 2 and 3 As shown, the display panel 3 provided in the embodiment of the present invention is a liquid crystal display panel, and the display panel 3 includes a first substrate 31 and a second substrate 32 arranged in parallel with each other, and a liquid crystal layer LC arranged between the first substrate 31 and the second substrate 32. When the first substrate 31 and the second substrate 32 are assembled, the liquid crystal layer LC is sealed by a frame sealant ( Figure 3 The display panel 3 includes a display area AA and a non-display area NA.

[0053] In particular, in an embodiment of the present invention, the display panel 3 further includes at least one dielectric stacking portion 311 disposed on the non-display area NA. At the same time, the second substrate 32 includes a partition wall (PS Wall) 312 having a plurality of openings 332 disposed corresponding to the dielectric stacking portion 311, and the material of the partition wall 312 may be a resin material. Optionally, the thickness of the dielectric stacking portion 311 in a direction perpendicular to the substrate substrate is greater than or equal to 2 μm and less than or equal to 2.5 μm. Of course, depending on the specific product, the designer may select other suitable thicknesses so that after the first substrate 31 and the second substrate 32 are boxed, the partition wall 312 is in direct contact with the first substrate 31.

[0054] Specifically, refer to Figure 3 As shown, the dielectric stacking part 311 is arranged on the first substrate 31. The first substrate 31 includes a driving circuit board 331 arranged on the first substrate 321 and a color resist layer 341 arranged on the driving circuit board 331. The dielectric stacking part 311 is arranged in the same layer as the color resist layer 341, so that the stacking of the position of the non-display area with the partition wall is completed in a one-step process by using the color resist layer 341. Because it is arranged in the same layer as the color resist layer, the contact between the display area and its columnar pad and the contact between the non-display area and the partition wall are both close, so that the support capacity of the display panel in the display area and the non-display area after the box is assembled is consistent.

[0055] In this embodiment, because the dielectric stacking portion 311 is set in the non-display area corresponding to the partition wall 312, when the two substrates of the display panel 3 are aligned, the first substrate 31 stacked by the dielectric stacking portion 311 is in direct contact with the partition wall 312, thereby forming good support for the first substrate 31 and the second substrate 32, so that when the non-display area NA is subjected to external force, the box thickness will not change significantly, thereby avoiding light leakage.

[0056] In addition, in this embodiment, a plurality of openings 332 are provided on the partition wall 312 for the flow and diffusion of liquid crystal, so that when the partition wall is in close contact with the dielectric stacking portion, the flow of liquid crystal is still not affected, thereby ensuring the uniformity of the liquid crystal in the display panel after the box is assembled, and ensuring that other display effects of the display panel are not affected while solving the light leakage problem.

[0057] In this embodiment, the first substrate 31 further includes an organic film layer 351 covering the dielectric stacking portion 311 and the color resist layer 341 , so as to further improve the protection of the driving circuit 331 and the color resist layer 341 on the first substrate 31 .

[0058] Specifically, refer to Figure 3As shown, the second substrate 32 further includes a black matrix layer 352. The black matrix layer 352 is a light absorbing material. In the display area, the black matrix layer 352 and the color resist layer 341 are arranged in a grid shape to form a shield between two color resist materials of different colors to prevent color mixing. The coverage area of ​​the black matrix layer 352 in the non-display area covers the entire non-display area so that the non-display area does not emit light.

[0059] In some optional embodiments, the opening 332 on the partition wall 312 is arranged corresponding to the black matrix layer 352 in the display area AA. Figure 4 As shown, for the partition wall 312 parallel to the display area AA, the black matrix layer 352 of the display area AA includes a portion in the Y direction and a portion in the X direction, that is, the black matrix layer 352 of the display area AA includes a portion perpendicular to the partition wall 312 and a portion parallel to the partition wall 312, and the opening 332 is on the extension line of the Y direction.

[0060] In the Rubbing process, when the fluff on the surface of the rubbing cloth of the Rubbing roller aligns and combs the surface of the second substrate, because the opening 332 in the partition wall 312 has a large height difference relative to the entire partition wall 312, the surface fluff passing through the opening 332 is severely collapsed. When the rubbing cloth passes through the display area again, the alignment channels formed on the substrate surface by the surface fluff corresponding to the opening 332 are different from the alignment channels formed at other positions, which will cause the display brightness and color to be uneven when the display panel is turned on, which is also called the Rubbing Mura problem.

[0061] In an embodiment of the present invention, by utilizing the pixel arrangement characteristics, the openings are set corresponding to the black matrix layer of the display area, so that the influence of the opening position on the fluff on the surface of the friction cloth in the Rubbing process occurs at the position corresponding to the black matrix layer of the display area, so that when the Rubbing roller passes through the display area, the influence of uneven display may no longer occur at the position corresponding to the color resistance, thereby avoiding Rubbing Mura defects by designing the distribution of the openings.

[0062] Optionally, the color resist layer 341 includes a plurality of sub-color resists of different colors distributed in an array, the color resist layer 341 is divided into a color resist portion including at least one sub-color resist, and the opening 332 of the partition wall 312 is arranged corresponding to the black matrix layer defining the color resist portion. For example, if the color resist portion includes three sub-color resists of red (R), green (G), and blue (B), the opening 332 is arranged so that one opening is arranged corresponding to every three sub-color resists.

[0063] In addition, it should be noted that Figure 2As shown, the spacer wall 312 is arranged in a strip shape parallel to each side of the display area, in order to provide good support for the first substrate 31 and the second substrate 32 according to the shape of the display area AA and the non-display area NA. The present invention does not limit whether the spacer wall 312 parallel to the X direction and the Y direction are connected, which is subject to the actual design needs of the designer. Among them, the X direction and the Y direction are perpendicular to each other.

[0064] Alternatively, if Figure 2 As shown, in the direction perpendicular to the first substrate, the projection area of ​​the dielectric stacking portion 311 is larger than the projection area of ​​the spacer wall 312 to ensure that the spacer wall 312 can contact the portion of the first substrate 31 stacked by the dielectric stacking portion 311 .

[0065] Optionally, although Figure 2 and Figure 3 As shown in the figure, there is a situation where a spacer wall 312 and a corresponding dielectric stacking portion 311 are included between one side of the display area AA and the frame sealant, but the present invention is not intended to be limited to this. In order to achieve a good and uniform support effect on the first substrate 31 and the second substrate 32 in the non-display area NA, a plurality of spacer walls 312 can be set between one side of the display area AA and the frame sealant. For example, three spacer walls 312 are set. Correspondingly, it can be understood that a plurality of dielectric stacking portions 311 are also set accordingly. Optionally, when the ratio of the projection area of ​​the spacer wall 312 on the second substrate 322 to the projection area of ​​the non-display area on the second substrate is greater than or equal to a preset threshold, for example, 10000μm 2 / mm 2 When the first substrate 31 and the second substrate 32 are well supported in the non-display area NA.

[0066] It is worth mentioning that Figure 3 In the example shown in FIG. 1 , when the color resist layer is disposed on the first substrate 31 , the dielectric stacking portion 311 is disposed on the same layer as the color resist layer, but the present invention is not limited thereto.

[0067] In another example, Figure 5 As shown, the color resist layer 542 is disposed on the second substrate 52. The first substrate 51 includes a driving circuit layer 531 disposed on the first substrate 521 and a dielectric stacking portion 511 disposed on the driving circuit layer 531. The dielectric stacking portion 511 may be a patterned organic material layer, which may be a material layer for making an organic protective layer. Generally, the thickness of the organic protective layer may meet the requirements of the dielectric stacking portion 511 in this embodiment. That is, the dielectric stacking portion in this embodiment may be easily formed to a required thickness by utilizing the process steps for making the organic protective layer.

[0068] In this embodiment, because the dielectric stacking portion 511 is provided in the non-display area corresponding to the partition wall 512, when the two substrates of the display panel 5 are aligned, the first substrate 51 stacked by the dielectric stacking portion 511 is in direct contact with the partition wall 512, thereby forming good support for the first substrate 51 and the second substrate 52, so that when the non-display area is subjected to external force, the thickness of the box will not change significantly, thereby avoiding light leakage.

[0069] Of course, those skilled in the art should understand that, in addition to the change in the dielectric stack portion according to the setting position of the color resist layer, the height and number of the dielectric stack portion in the above-described example; the number and setting position of the partition walls, and other features of their openings are also applicable to this example, and the functions and effects are similar, and will not be repeated here.

[0070] In yet another example, the dielectric stack portion may also be disposed on the second substrate.

[0071] Specifically, refer to Figure 6 As shown, the second substrate 62 includes a color resist layer 642 disposed on the second substrate 622, and the dielectric stacking portion 662 is disposed in the same layer as the color resist layer 642. Because it is disposed in the same layer as the color resist layer, the contact between the display area and its columnar spacer and the contact between the non-display area and the spacer wall are both close, so that the support capacity of the display panel in the display area and the non-display area after the box is assembled is consistent.

[0072] In this embodiment, because the dielectric stacking portion 662 is set in the non-display area corresponding to the partition wall 612, when the two substrates of the display panel 6 are aligned, the second substrate 62 is stacked by the dielectric stacking portion 662, so that the partition wall 612 can be in direct contact with the first substrate 61, and good support is formed for the first substrate 61 and the second substrate 62, so that when the non-display area is subjected to external force, the box thickness will not change significantly, thereby avoiding light leakage.

[0073] Of course, those skilled in the art should understand that, in addition to the change in the dielectric stack portion according to the setting position of the color resist layer, the height and number of the dielectric stack portion in the above-described example; the number and setting position of the partition walls, and other features of their openings are also applicable to this example, and the functions and effects are similar, and will not be repeated here.

[0074] Corresponding to the same inventive concept, refer to Figure 7 As shown, an embodiment of the present invention further provides a method for manufacturing the display panel described in the above embodiment, comprising:

[0075] S1, forming a first substrate and a second substrate respectively, comprising at least one dielectric stacking portion arranged on a non-display area of ​​a display panel, and a spacer wall having a plurality of openings arranged on the second substrate and corresponding to the dielectric stacking portion;

[0076] S2, aligning the first substrate with the second substrate, wherein the spacer wall and the dielectric stacking portion form a support when the second substrate is aligned with the first substrate.

[0077] In this embodiment, by providing at least one dielectric stacking portion in the non-display area of ​​the display panel and providing a partition wall having a plurality of openings corresponding to the dielectric stacking portion on the second substrate, the dielectric stacking portion and the partition wall can provide good support for the non-display area of ​​the display panel when the first substrate and the second substrate are assembled, while not affecting the fluidity of the liquid crystal, avoiding light leakage around the display area of ​​the display panel, and improving the display uniformity of the display panel. The manufacturing process is simple and easy to implement, and has broad application prospects.

[0078] Optionally, when making Figure 3 In the display panel 3 of the embodiment, in step S1, a driving circuit layer 331 is first formed on a first substrate 321. The first substrate 321 may be a glass substrate, and the driving circuit layer 331 may include a thin film transistor circuit, a scanning line Gate, a data line SD, and a pixel electrode line, etc., and an insulating layer GI or PVX may be included between each layer of lines. Then, a color resist material layer is formed on the driving circuit layer 331, and then the color resist material layer is patterned to form a color resist layer 341 located in a display area and a dielectric stacking portion 311 located in a non-display area.

[0079] In addition, a black matrix layer 352 is formed on the second substrate 32, and step S1 further includes forming a spacer wall 312 on the second substrate 32, and the opening 332 of the spacer wall 312 is arranged corresponding to the black matrix layer 352 of the display area AA. Specifically, the spacer wall with a plurality of openings can be formed by coating a spacer wall material, such as a resin material, on the second substrate, coating a photoresist on the spacer wall material, and performing photolithography on the spacer wall material using a mask.

[0080] Those skilled in the art should understand that because the dielectric stacking portion 311 of the present invention is intended to increase the height of the first substrate using a material of the same thickness as the color resist layer and is independent of the color of the material, the color resist material layer used to make the dielectric stacking portion 311 can be made of a resin material of any color of sub-color resists of various colors, and the present invention is not intended to be limiting.

[0081] Through the above arrangement, the dielectric stacking portion 311 can be formed on the first substrate by using the same process method and materials as the color resist layer, and only by simply adjusting the patterned mask. Other material layers formed in subsequent steps, such as the organic protective layer 351, are stacked at corresponding positions. When the two substrates of the display panel are aligned, the first substrate 31 stacked by the dielectric stacking portion 311 is in direct contact with the partition wall 312, thereby forming a good support for the first substrate and the second substrate, so that when the non-display area is subjected to external force, the thickness of the cell will not change significantly, thereby avoiding light leakage.

[0082] Optionally, when making Figure 5 In the display panel 5 of the embodiment, in step S1, when forming the first substrate 51, a driving circuit layer 531 can be formed on the glass substrate 521. The driving circuit layer 531 can include a thin film transistor circuit, a scanning line Gate, a data line SD, and a pixel electrode line, etc., and an insulating layer GI or PVX can be included between each layer of lines. Then, an organic material layer is formed on the driving circuit layer 531; and the organic material layer is patterned to form a dielectric stacking portion 511 located in the non-display area.

[0083] In addition, a black matrix layer 552 is formed on the second substrate 52. Step S1 also includes forming a spacer wall 512 on the second substrate 52. The openings of the spacer wall 512 are arranged corresponding to the black matrix layer 552 in the display area. Specifically, a spacer wall having a plurality of openings can be formed by coating a spacer wall material, such as a resin material, on the second substrate, coating a photoresist on the spacer wall material, and performing photolithography on the spacer wall material using a mask.

[0084] Through the above arrangement, the process method and materials for manufacturing the organic protective layer can be used, and the dielectric stacking portion 511 can be formed on the first substrate by simply adjusting the patterned mask. Other material layers formed in subsequent steps, such as the organic film layer 551, are stacked at corresponding positions. When the two substrates of the display panel are aligned, the first substrate 51 stacked by the dielectric stacking portion 511 is in direct contact with the spacer wall 512, thereby forming a good support for the first substrate and the second substrate, so that when the non-display area is subjected to external force, the thickness of the cell will not change significantly, thereby avoiding light leakage.

[0085] Optionally, when making Figure 6 In the display panel 6 of the embodiment, in step S1, when forming the first substrate 61, a driving circuit layer 631 may be formed on the glass substrate 621. The driving circuit layer 631 may include a thin film transistor circuit, a scanning line Gate, a data line SD, and a pixel electrode line, etc., and an insulating layer GI or PVX may be included between each layer of lines. Then, an organic protective layer, an alignment layer PI, etc. are formed on the driving circuit layer 631.

[0086] When forming the second substrate 62, a black matrix layer 652 may be formed on the second substrate 622, and a color resist material layer may be formed on the black matrix layer 652; and then the color resist material layer may be patterned to form a color resist layer 642 in the display area and a dielectric stack portion 662 in the non-display area.

[0087] In addition, step S1 also includes forming a spacer wall 612 on the second substrate 62, and the openings of the spacer wall 612 are arranged corresponding to the black matrix layer 652 of the display area. Specifically, the spacer wall 612 with a plurality of openings can be formed by coating a spacer wall material, such as a resin material, on the second substrate, coating a photoresist on the spacer wall material, and performing photolithography on the spacer wall material using a mask.

[0088] Through the above arrangement, the dielectric stacking portion 662 can be formed on the first substrate 62 by using the same process method and materials as the color resist layer, and only by simply adjusting the patterned mask. When the two substrates of the display panel are aligned, the second substrate 62 is stacked by the dielectric stacking portion 662, so that the partition wall 612 can directly contact the first substrate 61, and form a good support for the first substrate and the second substrate, so that when the non-display area is subjected to external force, the thickness of the cell will not change significantly, thereby avoiding light leakage.

[0089] Based on the same inventive concept, an embodiment of the present invention further provides a display device, including the display panel as described in the above embodiment. Since the display panel included in the display device provided in the embodiment of the present application corresponds to the display panel provided in the above embodiments, the previous implementation is also applicable to the use method provided in this embodiment, and will not be described in detail in this embodiment.

[0090] In this embodiment, the display device may be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame or a navigator.

[0091] In view of the existing problems, the present invention develops a display panel and a manufacturing method thereof, as well as a display device. By providing a non-display area of ​​at least one dielectric stacking portion and providing a partition wall with multiple openings arranged corresponding to the dielectric stacking portion, the first substrate and the second substrate can play a good supporting role for the non-display area of ​​the display panel through the dielectric stacking portion and the partition wall when the first substrate and the second substrate are assembled, and at the same time, the fluidity of the liquid crystal is not affected, light leakage around the display area of ​​the display panel is avoided, and the display uniformity of the display panel is improved. In addition, the manufacturing process is simple and easy to implement, and it has broad application prospects.

[0092] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
