[0033] In the present disclosure, "on", "formed on" and "disposed on" can mean that a layer is directly formed or disposed on another layer, or indirectly formed or disposed on another layer, that is, there are other layers between the two layers.

[0034] It should be noted that the terms "first", "second", and the like, can be used herein to describe various components, members, elements, regions, layers and / or sections, but these components, members, elements, regions, layers and / or sections should not be limited by these terms. Instead, these terms are used to differentiate one component, member, element, region, layer and / or section from another. Thus, for example, a first component, a first member, a first element, a first region, a first layer and / or a first section discussed below can be called a second component, a second member, a second element, a second region, a second layer and / or a second section without departing from the teachings of the present disclosure.

[0035] In the present disclosure, the term "disposed in the same layer" is used to mean that two layers, components, members, elements or sections can be formed by the same manufacturing process (e.g. a patterning process, etc.), and the two layers, components, members, elements or sections are generally formed of the same material. For example, two or more functional layers disposed in the same layer means that the functional layers disposed in the same layer can be formed using the same material layer and the same manufacturing process, thereby simplifying the manufacturing process of the display substrate.

[0036] In the present disclosure, the expression "patterning process" generally includes the steps of coating, exposing, developing, etching, stripping of photoresist, etc. The expression "one-time patterning process" means a process of forming a patterned layer, component, member, etc. using one mask plate.

[0037] In the related art of liquid crystal display panels, there is a problem that the liquid crystal display panel has a low ability to withstand external pressure. The cause of this phenomenon is unknown, and there is no good solution.

[0038] The inventors have observed that the possible causes of the phenomenon that the liquid crystal display panel has a low ability to withstand external pressure are as follows:

[0039] As Figures 1-2In the related art, the photo spacer (PS) process of the color film substrate of the thin film transistor liquid crystal display panel (TFT-LCD) is performed on the array substrate side (PS On Array, POA), in order to improve the non-sticking problem of the alignment liquid at the via hole for connecting the pixel electrode 400 to the source-drain metal layer 401 in the planarization layer 40 on the array substrate side, a protective photo spacer 402 is used to cover the via hole to prevent the alignment liquid from accumulating at the hole edge to cause non-sticking; in addition, in the related art, the color resistance layer on the color film substrate side adopts a stripe color resistance design, and the thickness of the blue color resistance layer 403 is greater than the thickness of the red color resistance layer 404 and the thickness of the green color resistance layer 405, so that there is a step difference between different color resistance layers on the color film substrate side; and the main photo spacer 407 is arranged in the overlapping area of a part of the blue color resistance layer 403 and the black matrix 406, and the protective photo spacer 402 is arranged to cover the via hole when the main photo spacer 407 is not arranged in another part of the blue color resistance layer 403; the sub photo spacer 408 is arranged in the overlapping area of the red color resistance layer 404 and the black matrix 406, and the sub photo spacer 408 is arranged in the overlapping area of the green color resistance layer 405 and the black matrix 406.

[0040] From the preparation process, the protective photo spacer 402 and the sub photo spacer 408 are both formed by using a half tone mask, and theoretically have the same thickness. In a normal state, the main photo spacer 407 plays a supporting role in the liquid crystal display panel; when the liquid crystal display panel is subjected to a large external pressure, in an ideal case, the sub photo spacer 408 also plays a supporting role by contacting the red color resistance layer 404 and the green color resistance layer 405; however, due to the fact that the thickness of the blue color resistance layer 403 is greater than the thickness of the red color resistance layer 404 and the thickness of the green color resistance layer 405, the protective photo spacer 402, which originally only plays a protective role and does not play a supporting role, also plays a supporting role by contacting the blue color resistance layer 403, thereby forming three-stage supports in the liquid crystal display panel, wherein the three-stage supports include a first-stage support in which the main photo spacer 407 contacts a part of the blue color resistance layer 403, a second-stage support in which the sub photo spacer 408 contacts the red color resistance layer 404 and the green color resistance layer 405, and a third-stage support in which the protective photo spacer 402 contacts another part of the blue color resistance layer 403. That is, when the liquid crystal display panel is subjected to a large external pressure, due to the fact that the protective photo spacer has a step difference with the color resistance layer, the protective photo spacer is higher than the sub photo spacer which is aligned with the lower color resistance layer around the protective photo spacer, thereby forming a three-stage step difference, which reduces the surface pressure bearing capacity of the liquid crystal display panel.

[0041] Therefore, one embodiment of the present application provides a liquid crystal display panel, comprising a color filter substrate, an array substrate oppositely arranged with the color filter substrate, and a liquid crystal layer between the color filter substrate and the array substrate; the array substrate comprises a first substrate, a driving circuit layer, a planarization layer, an array of pixel electrodes, and a spacer layer which are sequentially stacked on the first substrate; the color filter substrate comprises a second substrate, a black matrix layer, and a color resistance layer which are arranged on the second substrate; the driving circuit layer comprises an array of thin film transistors; the planarization layer comprises a via for electrically connecting the pixel electrode and a first electrode of the thin film transistor; the spacer layer comprises a main spacer, an auxiliary spacer, and a protective spacer, the orthogonal projection of the spacer layer on the first substrate is covered by the orthogonal projection of the black matrix layer on the first substrate, the protective spacer covers the via, and the orthogonal projection of the color resistance layer on the first substrate does not overlap with the orthogonal projection of the protective spacer on the first substrate.

[0042] In one specific example, as shown in Figure 3 The liquid crystal display panel comprises a color filter substrate, an array substrate oppositely arranged with the color filter substrate, and a liquid crystal layer 300 between the color filter substrate and the array substrate, the liquid crystal layer 300 comprises liquid crystal molecules, the array substrate and the color filter substrate are bonded together by a frame adhesive, and the liquid crystal layer 300 is formed in a closed area surrounded by the frame adhesive; the array substrate comprises a first substrate 201, a driving circuit layer, a planarization layer 208, an array of pixel electrodes 204, and a spacer layer which are sequentially stacked on the first substrate 201; the driving circuit layer comprises a gate electrode 206, a gate insulating layer 207, a source-drain metal layer 2021, and a passivation layer 203; the color filter substrate comprises a second substrate 101, a black matrix layer 102, and a color resistance layer which are arranged on the second substrate 101, and the second substrate 101 comprises an array of sub-pixel regions, and the black matrix layer 102 is provided with a plurality of openings corresponding to the sub-pixel regions; the driving circuit layer comprises an array of thin film transistors, and the thin film transistors comprise a source-drain metal layer 2021; the planarization layer 208 comprises a via 2030 for electrically connecting the pixel electrode 204 and a first electrode in the source-drain metal layer 2021 of the thin film transistor; the spacer layer comprises a main spacer 2051, an auxiliary spacer 2052, and a protective spacer 2053; the orthogonal projection of the spacer layer on the first substrate 201 is covered by the orthogonal projection of the black matrix layer 102 on the first substrate 201; the protective spacer 2053 covers the via 2030; and the orthogonal projection of the color resistance layer on the first substrate 201 does not overlap with the orthogonal projection of the protective spacer 2053 on the first substrate 201.

[0043] Further, as shown in Figure 3As shown, the color filter substrate also includes a common electrode layer disposed on the second substrate 101, or the array substrate also includes a common electrode layer disposed on the first substrate 201; the liquid crystal molecules of the liquid crystal layer 300 are twisted under the action of the driving electric field formed between the pixel electrode 204 and the common electrode, control the polarization direction of the incident light, and control the transmittance of the incident light under the cooperation of the two polarizing plates disposed on the light entrance side and the light exit side of the liquid crystal display panel, and realize color display in combination with the color resistance layer.

[0044] Further, as shown in Figure 3 The array substrate can also be referred to as an Array substrate or a TFT substrate, and the array substrate includes a first substrate 201, a plurality of scan lines (or gate lines, Gate lines) extending in a first direction (for example, the row direction) and a plurality of data lines (Data lines) extending in a second direction (for example, the column direction) formed on the first substrate 201. The plurality of scan lines and the plurality of data lines cross to define an array of sub-pixel regions. It can be understood that the sub-pixel regions on the array substrate correspond one-to-one to the sub-pixel regions on the color filter substrate. The one-to-one correspondence can be understood as the orthographic projection of the sub-pixel regions on the array substrate on the first substrate 201 coinciding with the orthographic projection of the sub-pixel regions on the color filter substrate on the second substrate 101. Each sub-pixel region of the array substrate is provided with a pixel electrode 204 and a thin film transistor (TFT), wherein the gate 206 of the thin film transistor is connected to the scan line, the first pole (for example, the drain) is connected to the pixel electrode 204 belonging to the same sub-pixel region, for example Figure 3 The source-drain metal layer 2021 shown in the source-drain metal layer 2021 realizes the first pole of the thin film transistor, and the second pole (for example, the source) is connected to the data line; the pixel electrode 204 and the common electrode are indium tin oxide (ITO) electrodes or indium zinc oxide (IZO) electrodes.

[0045] Further, as shown in Figure 3 The liquid crystal display panel is formed by the array substrate and the color filter substrate, filled with a liquid crystal layer in between, and supported by a spacer. The spacer can include a main spacer 2051 and an auxiliary spacer 2052. The auxiliary spacer 2052 serves as a backup spacer and plays a role in strengthening the supporting force when the liquid crystal display panel is subjected to a large force. The thickness of the main spacer 2051 is greater than the thickness of the auxiliary spacer 2052, for example, the thickness of the auxiliary spacer 2052 can be 70% to 95% of the thickness of the main spacer 2051. In the normal state of the array substrate and the color filter substrate, the main spacer plays a supporting role. When the display panel is subjected to a large external force, the auxiliary spacer 2052 can also play a supporting role to improve the pressure resistance, and when the pressure is eliminated, the main spacer 2051 and the auxiliary spacer 2052 can provide a restoring force. The present embodiment can improve the supporting capacity of the spacer and prevent various Mura or defects from occurring by setting the main spacer and the auxiliary spacer with different thicknesses.

[0046] Further, as shown in Figure 3 the spacer layer in the array substrate includes a protective spacer 2053 covering the via 2030. The protective spacer is used to cover the via to prevent the alignment liquid from accumulating at the via, effectively improving the problem of alignment liquid not adhering at the via when the spacer process of the color film substrate of the thin film transistor liquid crystal display panel is performed on the array substrate side.

[0047] Further, as shown in Figure 3 the thickness of the protective spacer 2053 in the array substrate can be equal to the thickness of the auxiliary spacer 2052. Furthermore, in order to maintain the liquid crystal cell thickness, ensure the liquid crystal margin (LC Margin), improve the alignment liquid not adhering at the via, and simplify the process flow, a gray-tone mask or a half-tone mask is used to manufacture the main spacer, the auxiliary spacer, and the protective spacer. The embodiment can effectively reduce the number of patterning processes (Mask) and effectively reduce the manufacturing cost.

[0048] In a specific example, as shown in Figures 3-4 the color resistance layer includes a plurality of first color resistance layers, a plurality of second color resistance layers 2032, and a plurality of third color resistance layers 2033, a part of the plurality of first color resistance layers corresponding to the first color resistance layer of the protective spacer 2053 is arranged as a plurality of first color resistance layer groups 2031 arranged along the first direction X, the first color resistance layer group 2031 adopts an island-shaped (Island) color resistance design, that is, the first color resistance layer group 2031 includes a plurality of first sub-color resistance layers 20311 arranged along the second direction Y; the second color resistance layer group 2032 and the third color resistance layer group 2033 both adopt a strip-shaped color resistance design; another part of the plurality of first color resistance layers corresponding to the first color resistance layer of the main spacer 2051 is a first color resistance layer 2034 adopting a strip-shaped color resistance design; the black matrix layer includes a first black matrix layer 1021 extending along the first direction X.

[0050] Further, as shown in Figures 3-4As shown, the orthographic projection of the first color resist layer 2031 on the first substrate 201 does not overlap with the orthographic projection of the first black matrix layer 1021 on the first substrate 201, and the orthographic projection of the protective spacer 2053 on the first substrate 201 is covered by the orthographic projection of the first black matrix layer 1021 on the first substrate 201; thus, the orthographic projection of the first color resist layer 2031 on the first substrate 201 does not overlap with the orthographic projection of the protective spacer 2053 on the first substrate 201.

The first color resist layers 1131, second color resist layers 1132, and third color resist layers 1133 do not adopt an island-shaped color resist design, but rather adopt a color resist layer with a cut-out area in the alignment region with the main spacer 2051, the auxiliary spacer 2052, and the protective spacer 2053.

[0085] In the embodiment, the first color resist layer on the color film substrate is designed in an island shape, which eliminates the risk of increasing the surface pressure caused by the multi-segment step difference of the unexpected alignment of the protective spacer on the array substrate due to the step difference of the color resist layer in the process of arranging the color film substrate spacer on the array substrate side, thereby improving the design allowance of the protective spacer on the array substrate side.

[0088] This embodiment improves the design margin of the auxiliary spacer by adopting an island-shaped design for the second color barrier layer.

[0091] This embodiment improves the design margin of the auxiliary spacer by adopting an island-shaped design for the third color barrier layer; at the same time, since the first, second, and third color barrier layers all adopt an island-shaped design, it can save process steps.

[0105] The embodiment can effectively avoid forming three-step steps in the protective spacers due to the existence of the color resist layer when the liquid crystal display panel is subjected to external pressure by setting the first color resist layer as a blue color resist layer. The flexibility and applicability of the color resist layer design can be effectively improved by setting the second color resist layer as one of red color resist layers and green color resist layers and the third color resist layer as the other of red color resist layers and green color resist layers.

[0106] In a possible implementation, the main spacers, the auxiliary spacers, and the protective spacers are arranged in the same layer.

[0107] In a specific example, as shown in FIG. 20, the main spacers 2051, the auxiliary spacers 2052, and the protective spacers 2053 are arranged in the same layer. Figures 3-10

[0108] The embodiment can effectively reduce the generation cost and improve the production efficiency by using a half-tone mask to form the main spacers, the auxiliary spacers, and the protective spacers on the array substrate in one photoetching process.

[0109] In a possible implementation, the thickness of the main spacers is greater than the thickness of the auxiliary spacers, and the thickness of the auxiliary spacers is the same as that of the protective spacers.

[0110] In a specific example, as shown in FIG. 20, the thickness of the main spacers 2051 is greater than the thickness of the auxiliary spacers 2052, and the thickness of the auxiliary spacers 2052 is the same as that of the protective spacers 2053. Figures 3-10 Further, as shown in FIG. 11B, the color resist layer includes a plurality of second color resist layers 1132 arranged along the first direction X, and the second color resist layers 1132 are one of red color resist layers and green color resist layers.

[0111] Figures 3-10 ​​​​As shown, in order to form the main spacers 2051, the auxiliary spacers 2052 and the protective spacers 2053 with different thicknesses, generally, a half-tone mask is used to form the main spacers 2051, the auxiliary spacers 2052 and the protective spacers 2053 on the array substrate, the half-tone mask includes two regions with different light transmittances, in the process of forming the main spacers 2051, the auxiliary spacers 2052 and the protective spacers 2053, the half-tone mask is used to expose the film layer on the array substrate to be exposed, and then a developing process is used for processing, so that the main spacers 2051, the auxiliary spacers 2052 and the protective spacers 2053 are formed; wherein the light transmittance of the corresponding region of the main spacers 2051 on the half-tone mask is different from the light transmittance of the corresponding region of the auxiliary spacers 2052 and the protective spacers 2053 on the half-tone mask, and the light transmittance of the corresponding region of the auxiliary spacers 2052 on the half-tone mask is the same as the light transmittance of the corresponding region of the protective spacers 2053 on the half-tone mask, so that the thickness of the main spacers 2051 is greater than the thickness of the auxiliary spacers 2052, the thickness of the main spacers 2051 is greater than the thickness of the protective spacers 2053, and the thickness of the auxiliary spacers 2052 is the same as the thickness of the protective spacers 2053.

[0112] Further, as shown in the figure, Figures 3-10 Figures 3-10 From the preparation process, the protective spacers 2053 and the auxiliary spacers 2052 theoretically have the same thickness, but because the half-translucent film opening of the protective spacers 2053 is smaller than the half-translucent film opening of the auxiliary spacers 2052, the exposure amount of the protective spacers 2053 is greatly affected by the light angle and the like, so in practice, the thickness of the protective spacers 2053 is slightly smaller than the thickness of the auxiliary spacers 2052.

[0113] It should be noted that the thicknesses are the same here is ideal, considering the process reasons, the thickness of the protective spacers is slightly lower than the thickness of the auxiliary spacers, and the specific thicknesses that are the same refer to the equality under the condition of process fluctuation, that is, the thicknesses are the same within the error of less than 5% or 8%.

[0114] By setting the thickness of the main spacers to be greater than the thickness of the auxiliary spacers and the thickness of the auxiliary spacers to be the same as the thickness of the spacers, the process flow can be saved and the process flow can be simplified.
