Description

Technical Field

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

[0002] During conventional mechanical testing, a large external force is usually applied to the liquid crystal display panel. Since the surface of the spacer on the color filter substrate side facing the array substrate is covered with a very thin alignment layer, the alignment layer will be worn under the pressure of external force to expose the spacer, causing the spacer to slide directly against the alignment layer on the array substrate side. When the test conditions are harsh, the alignment layer on the array substrate side is severely worn, resulting in observable image abnormalities.

[0003] In the process of studying and practicing the prior art, the inventors of the present application found that since the hardness of the spacer is much greater than the hardness of the alignment layer on the array substrate side, when the two slide relative to each other, the alignment layer with lower hardness is worn to a greater extent.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the various embodiments can be combined with each other but will not be repeated one by one, and in the absence of contrary instructions, the directional words used, such as "upper" and "lower", usually refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device; the terms "first", "second", "third", etc. are used only as markings, and no numerical requirements are imposed or order is established.

[0027] The present application provides a liquid crystal display panel, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0028] Figure 1 The LCD panel 100 shown is based on a Fringe Field Switching (FFS) technology driving architecture, but is not limited thereto. For example, it may be a LCD panel 100 based on an In-Plane Switching (IPS) technology driving architecture, or a LCD panel 100 based on a Vertical Alignment (VA) technology driving architecture, or a LCD panel 100 based on a Twisted Nematic (TN) technology driving architecture, and so on.

[0029] Please refer to Figure 1 An embodiment of the present application provides a liquid crystal display panel 100 , which includes an array substrate 10 , an opposing substrate 20 disposed on the array substrate 10 , and liquid crystal disposed between the array substrate 10 and the opposing substrate 20 .

[0030] Optionally, the array substrate 10 includes a first substrate 11 and a first alignment layer 12 , and the first alignment layer 12 is disposed on the first substrate 11 .

[0031] The counter substrate 20 includes a second substrate 21, a spacer 22 and a transition layer 23. The spacer 22 is disposed on a side of the second substrate 21 close to the array substrate 10. At least a portion of the transition layer 23 covers a side of the spacer 22 close to the array substrate 10. The hardness of the first alignment layer 12 is less than that of the spacer 22.

[0032] The hardness of the transition layer 23 is smaller than the hardness of the spacer 22 .

[0033] It should be understood that in the existing liquid crystal display panel, although part of the alignment layer material will remain on the spacer, due to the high spacer and steep slope, the thickness of the alignment film material retained is about 30% to 40% of that in other areas, and the thickness of the alignment film is generally less than or equal to 0.1 micron, so the alignment film material retained on the spacer is at most 0.04 micron. Based on the extremely thin alignment film material on the spacer, when the liquid crystal display panel is squeezed or collided by external force, such as mechanical testing, the extremely thin alignment film material will be quickly worn away and the spacer will be exposed. Then, in the subsequent external force squeezing or collision process, the exposed spacer will have relative sliding friction with the alignment film on the array substrate side. Since the hardness of the spacer is much greater than the hardness of the alignment film, the alignment film will be worn a lot during the relative sliding friction process, which will cause alignment abnormality on the one hand, making the liquid crystal deflection abnormal, and then causing abnormal display screen; on the other hand, the debris of the alignment film worn away will be dispersed in the liquid crystal, which will also cause abnormal display screen.

[0034] Among them, the liquid crystal display panel 100 of the embodiment of the present application is provided with a transition layer 23 with a hardness less than that of the spacer 22. When the transition layer 23 and the first alignment layer 12 are in relative sliding friction, the hardness of the transition layer 23 is relatively small, so the wear degree of the first alignment layer 12 can be reduced, thereby reducing the risk of abnormal display images.

[0035] Optionally, in some embodiments of the present application, the thickness of a portion of the transition layer 23 corresponding to the spacer 22 is greater than the thickness of the first alignment layer 12 .

[0036] It is understandable that the portion of the transition layer 23 corresponding to the spacer 22 has a greater thickness, which can reduce the risk of exposing the spacer 22 due to the transition layer 23 being worn away, thereby reducing the degree of wear of the first alignment layer 12 .

[0037] Please refer to Figure 1The array substrate 10 further includes a thin film transistor tft, a pixel electrode pix and a common electrode com, the thin film transistor tft is connected to the pixel electrode pix, and the common electrode com and the pixel electrode pix are arranged in different layers. The common electrode com and the pixel electrode pix are used to connect different voltages to form an electric field, so that the liquid crystal is deflected under the action of the electric field, thereby realizing the display function.

[0038] Optionally, the thin film transistor TFT is a bottom gate transistor, but is not limited thereto, and may be, for example, a top gate transistor, a double gate transistor, or a vertical transistor.

[0039] exist Figure 1 In the embodiment, the thin film transistor tft includes a gate g01, an active layer p01, a source s01 and a drain d01. The gate g01 is disposed on a first substrate 11. The gate insulating layer gi1 covers the gate g01. The active layer p01 is disposed on the gate insulating layer gi1. The source s01 is connected to one side of the active layer p01, and the drain d01 is connected to the other side of the active layer p01. The drain d01 is connected to the pixel electrode pix.

[0040] Optionally, the array substrate 10 further includes a passivation layer 13, and the passivation layer 13 covers the source electrode s01, the drain electrode d01 and the pixel electrode pix. The common electrode com is disposed on the passivation layer 13. The first alignment layer 12 covers the passivation layer 13 and the common electrode com.

[0041] It is important to understand that Figure 1 What is shown is only one implementation of the present application. In some implementations, the architecture of the thin film transistor tft, the film layer positions of the pixel electrode pix and the common electrode com can be adjusted according to actual conditions as long as the FFS architecture is satisfied.

[0042] Please continue to refer to Figure 1 The counter substrate 20 further includes a black matrix layer bm and a color filter layer cf. The black matrix layer bm is disposed on a side of the second substrate 21 close to the array substrate 10. A plurality of openings are provided on the black matrix layer bm. The color filter layer cf is disposed in the openings. The spacer 22 is disposed on a side of the black matrix layer bm close to the array substrate 10.

[0043] It is understandable that the color filter layer cf may not only be disposed on the counter substrate 20 , but in some embodiments, the color filter layer cf may also be integrated on the array substrate 10 .

[0044] Optionally, the color filter layer cf includes a red color resist, a green color resist and a blue color resist.

[0045] Optionally, in the liquid crystal display panel 100 of one or more embodiments of the present application, the counter substrate 20 further includes a planar layer pn. The planar layer pn covers the black matrix layer bm and the color filter layer cf. The spacer 22 is disposed on a side of the planar layer pn close to the array substrate 10 .

[0046] Optional, see Figure 1 In the liquid crystal display panel 100 of one or more embodiments of the present application, the transition layer 23 may cover the surface of the spacer 22 but not the area outside the spacer 22 to reduce light loss, but is not limited thereto. For example, the transition layer 23 may be laid on the entire surface, covering not only the surface of the spacer 22 but also the surface of the planar layer pn to save photomasks.

[0047] Optionally, if the transition layer 23 covers the surface of the spacer 22 and is located in the area of ​​the black matrix layer bm, the material of the transition layer 23 can be a light-transmitting material or a light-shielding material. If the transition layer 23 is laid on the entire surface, the material of the transition layer 23 is a highly light-transmitting material.

[0048] Optionally, the material of the planar layer pn includes but is not limited to organic compounds, such as transparent photoresist, acrylic resin, epoxy resin, phenolic resin, polyamide resin or polyimide resin.

[0049] Optionally, the thickness of the planar layer pn is between 1.5 microns and 2.5 microns, for example, 1.5 microns, 1.6 microns, 1.7 microns, 1.8 microns, 1.9 microns, 2.0 microns, 2.1 microns, 2.2 microns, 2.3 microns, 2.4 microns or 2.5 microns.

[0050] Optionally, in some embodiments of the present application, the counter substrate 20 further includes a second alignment layer 24 , which covers a side of the transition layer 23 close to the array substrate 10 , and the material of the second alignment layer 24 is the same as that of the first alignment layer 12 .

[0051] The second alignment layer 24 includes a first portion 241 and a second portion 242 connected to each other. The first portion 241 corresponds to and covers the spacer 22, and the second portion 242 is located at the periphery of the spacer 22. The thickness of the first portion 241 is smaller than that of the second portion 242.

[0052] It is understood that the first alignment layer 12 and the second alignment layer 24 are made of the same material, so that the hardness of the two layers is consistent. In addition, since the material forming the second alignment layer 24 has fluidity, the material on the spacer 22 will flow to other areas and become thinner, so that the thickness of the first portion 241 is less than the thickness of the second portion 242.

[0053] Optionally, the materials of the first alignment layer 12 and the second alignment layer 24 may be polyimide, but are not limited thereto.

[0054] Optionally, the thickness of the second portion 242 of the second alignment layer 24 is between 0.065 microns and 0.1 microns, for example, it can be 0.065 microns, 0.07 microns, 0.08 microns, 0.09 microns or 0.1 microns; the thickness of the first portion 241 is between 0.0195 microns and 0.04 microns, for example, it can be 0.0195 microns, 0.02 microns, 0.025 microns, 0.03 microns, 0.035 microns or 0.4 microns.

[0055] In some embodiments, the thickness of the first portion 241 is between 30% and 40% of the thickness of the second portion 242, for example, 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39% or 40%.

[0056] Optionally, in some embodiments of the present application, the spacer 22 has a slope angle a, and the slope angle a is between 30 degrees and 75 degrees.

[0057] It can be understood that the larger the slope angle a is, the steeper the spacer 22 is, and then, it is more difficult for the transition layer 23 and the second alignment layer 24 to attach to the spacer 22, so that the thickness of the portion of the transition layer 23 corresponding to the spacer 22 and the first portion 241 of the second alignment layer 24 are thinner, and then the risk of the transition layer 23 and the first portion 241 being worn away and exposing the spacer 22 is greater; on the other hand, when the spacer 22 has the same height and bottom surface size, the larger the slope angle a is, the larger the top surface area is, and the better its supporting effect is. Therefore, considering the support of the spacer 22 and its exposure risk, the slope angle a of the spacer 22 is selected to be between 30 degrees and 75 degrees.

[0058] For example, the slope angle a can be 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees or 75 degrees.

[0059] Further optionally, the slope angle a may be between 30 degrees and 45 degrees to reduce the risk of the spacers 22 being exposed.

[0060] Optionally, in some embodiments of the present application, the hardness of the transition layer 23 is greater than the hardness of the first alignment layer 12 .

[0061] It is understandable that the hardness of the transition layer 23 is between the first alignment layer 12 and the spacer 22 , so that the hardness difference between the transition layer 23 and the first alignment layer 12 is smaller than the hardness difference between the spacer 22 and the first alignment layer 12 , thereby reducing the degree of wear of the first alignment layer 12 .

[0062] Optionally, based on the pencil hardness standard, the hardness of the spacer 22 is between 8H and 12H, and the hardness of the first alignment layer 12 is between 2H and 3H.

[0063] It is understood that the spacer 22 needs to maintain the thickness of the liquid crystal layer, so the spacer 22 needs to have a relatively high hardness. For example, the hardness of the spacer 22 can be 8H, 9H, 10H, 11H or 12H. The hardness of the first alignment layer 12 can be 2H or 3H.

[0064] Optionally, in some embodiments of the present application, the hardness of the transition layer 23 may also be equal to the hardness of the first alignment layer 12 .

[0065] The hardness of the transition layer 23 is greater than that of the first alignment layer 12 , but the hardness of the transition layer 23 is equal to that of the first alignment layer 12 , so that there is no hardness difference between the transition layer 23 and the first alignment layer 12 , further reducing the risk of the first alignment layer 12 being worn.

[0066] Optionally, the material of the transition layer 23 may be consistent with or different from the material of the first alignment layer 12 , as long as the hardness of the two is the same.

[0067] Optionally, in some embodiments of the present application, the hardness of the transition layer 23 may also be smaller than the hardness of the first alignment layer 12 .

[0068] It can be understood that, based on the mechanism that the film layer with smaller hardness is worn to a relatively greater extent due to the friction between two film layers with different hardnesses, a transition layer 23 with a hardness lower than that of the first alignment layer 12 is used to have relative sliding friction with the first alignment layer 12, so that the degree of wear of the first alignment layer 12 is greatly reduced, thereby reducing the risk of display abnormalities.

[0069] Secondly, since the hardness of the transition layer 23 is relatively low, when the transition layer 23 and the first alignment layer 12 slide relative to each other, the transition layer 23 is worn more and more debris is easily formed. Therefore, in order to reduce the overall debris, the hardness difference between the transition layer 23 and the first alignment layer 12 can be set smaller than the hardness difference between the spacer 22 and the first alignment layer 12.

[0070] That is, not only the chipping rate of the entire panel is reduced, but also the degree of wear of the first alignment layer 12 is greatly reduced, thereby greatly improving the display yield of the display panel.

[0071] In addition, based on the low hardness of the transition layer 23, the transition layer 23 has good flexibility. When external force is applied to the liquid crystal display panel 100, the transition layer 23 is arranged on the spacer 22. The transition layer 23 has the effect of buffering and releasing stress, which can reduce the pressure of the transition layer 23 on the first alignment layer 12, thereby reducing friction and reducing the degree of wear between the two.

[0072] Optionally, based on the fact that the hardness of the transition layer 23 is less than that of the first alignment layer 12 , the material of the transition layer 23 includes but is not limited to acrylic (PMMA), thermoplastic elastomer (TPE), polycarbonate, and polyvinyl alcohol.

[0073] Please refer to Figure 2 Based on the above embodiments, in some embodiments of the present application, the portion of the transition layer 23 corresponding to the spacer 22 also has a concave-convex structure.

[0074] It can be understood that the concavo-convex structure makes the surface of the transition layer 23 rough. When the transition layer 23 and the first alignment layer 12 slide relative to each other, the rough surface of the transition layer 23 increases the friction between the transition layer 23 and the first alignment layer 12, so as to reduce the relative sliding distance, thereby reducing the wear area of ​​the first alignment layer 12.

[0075] Optionally, in some embodiments of the present application, a portion of the transition layer 23 corresponding to the spacer 22 has a recessed portion 23 a , and the periphery of the recessed portion 23 a is closed.

[0076] It can be understood that, since the liquid material of the second alignment layer 24 will be coated on the transition layer 23, the recessed portion 23a can intercept most of the alignment layer material and cover the transition layer 23, thereby increasing the thickness of the first portion 241 of the second alignment layer 24, thereby reducing the risk of the first portion 241 of the second alignment layer 24 being worn away; and since the hardness of the second alignment layer 24 and the first alignment layer 12 tend to be consistent, the degree of mutual wear between the two is relatively low, so the risk of the first alignment layer 12 being worn can be further reduced.

[0077] Figure 3 FIG. 1 is a schematic diagram of a liquid crystal display panel 100 according to one or more embodiments of the present application. Figure 1 and Figure 2 The liquid crystal display panel 100 of the corresponding embodiment and the liquid crystal display panel 100 of more embodiments of the present application use the conventional film layer in the opposing substrate 20 as the transition layer 23 without additionally providing the transition layer 23 , thus saving the process and cost.

[0078] exist Figure 3 , parts different from those of the above-described embodiment will be described to avoid redundancy.

[0079] Please refer to Figure 3 The transition layer 23 is a flat layer pn, and the transition layer 23 covers a side of the spacer 22 close to the array substrate 10 , and covers a side of the second substrate 21 close to the array substrate 10 .

[0080] The transition layer 23 includes a connected covering portion 231 and a flat portion 232, wherein the covering portion 231 covers the side of the spacer 22 close to the array substrate 10. The flat portion 232 covers the side of the second substrate 21 close to the array substrate 10 and is located at the periphery of the spacer 22. The flat portion 232 covers the black matrix layer bm and the color filter layer cf.

[0081] It is understandable that the present application reuses the flat layer pn as the transition layer 23 without additionally preparing the transition layer 23, thus saving the process and cost. Among them, although the transition layer 23 is a flat layer pn, so that the transition layer 23 has leveling properties, the transition layer 23 will not fill the spacer 22 because the spacer 22 is relatively high. The present application can adjust the thickness of the transition layer 23 and / or the height of the spacer 22 so that the transition layer 23 will not fill the spacer 22.

[0082] Secondly, due to the material properties of the planar layer pn, the hardness of the transition layer 23 is greater than that of the first alignment layer 12. Optionally, the hardness of the transition layer 23 is between 4H and 6H, for example, 4H, 5H or 6H.

[0083] Optionally, the thickness of the covering portion 231 is less than the thickness of the flat portion 232. The thickness of the covering portion 231 is between 30% and 50% of the thickness of the flat portion 232, for example, 30%, 35%, 40%, 45% or 50%.

[0084] Optionally, the thickness of the flat portion 232 is between 1.5 microns and 2.5 microns, for example, 1.5 microns, 1.6 microns, 1.7 microns, 1.8 microns, 1.9 microns, 2.0 microns, 2.1 microns, 2.2 microns, 2.3 microns, 2.4 microns or 2.5 microns.

[0085] Optionally, the thickness of the covering portion 231 is greater than the thickness of the first alignment layer 12 , so as to reduce the risk of the spacers 22 being exposed.

[0086] Please refer to Figure 4 In some embodiments of the present application, based on Figure 3 In the corresponding embodiment of the liquid crystal display panel 100 , the side of the covering portion 231 close to the array substrate 10 has a concave-convex structure.

[0087] It can be understood that the concavo-convex structure makes the surface of the transition layer 23 rough. When the transition layer 23 and the first alignment layer 12 slide relative to each other, the rough surface of the transition layer 23 increases the friction between the transition layer 23 and the first alignment layer 12, so as to reduce the relative sliding distance, thereby reducing the wear area of ​​the first alignment layer 12.

[0088] Optionally, in some embodiments of the present application, a side of the covering portion 231 close to the array substrate 10 has a recessed portion 23 a , and the periphery of the recessed portion 23 a is closed.

[0089] It can be understood that, since the liquid material of the second alignment layer 24 will be coated on the transition layer 23, the recessed portion 23a can intercept most of the alignment layer material and cover the transition layer 23, thereby increasing the thickness of the first portion 241 of the second alignment layer 24, thereby reducing the risk of the first portion 241 of the second alignment layer 24 being worn away; and since the hardness of the second alignment layer 24 and the first alignment layer 12 tend to be consistent, the degree of mutual wear between the two is relatively low, so the risk of the first alignment layer 12 being worn can be further reduced.

[0090] The liquid crystal display panel 100 of the embodiment of the present application includes an array substrate 10 and an opposing substrate 20, wherein the opposing substrate 20 includes a second substrate 21, a spacer 22 and a transition layer 23, wherein the spacer 22 is disposed on a side of the second substrate 21 close to the array substrate 10, wherein at least a portion of the transition layer 23 covers a side of the spacer 22 close to the array substrate 10, wherein the hardness of the first alignment layer of the array substrate 10 is less than that of the spacer 22. The hardness of the transition layer 23 is less than that of the spacer 22.

[0091] In the embodiment of the present application, a transition layer having a hardness less than that of the spacer 22 is provided. When the transition layer slides relative to the first alignment layer, the degree of wear of the first alignment layer can be reduced, thereby reducing the risk of abnormal display images.

[0092] The above is a detailed introduction to a liquid crystal display panel provided in an embodiment of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
