Description

Liquid crystal display panel and display device

[0001] The present application claims priority to Chinese Patent Application No. 2024111109938, filed on August 13, 2024, the disclosure of which is incorporated herein in its entirety as part of the present application. TECHNICAL FIELD

[0002] Embodiments of the present disclosure relate to a liquid crystal display panel and a display device. BACKGROUND

[0003] Liquid crystal display panels have become mainstream display devices due to their fast response speed, high integration, low power consumption, and other advantages. A liquid crystal display panel generally includes an array substrate provided with a thin film transistor array, a counter substrate provided with a black matrix and / or a color filter, and a liquid crystal layer between the array substrate and the counter substrate. The array substrate and the counter substrate are oppositely arranged to form a liquid crystal cell, and liquid crystal molecules fill the liquid crystal cell to form the liquid crystal layer.

[0004] When the liquid crystal display panel displays, the pixel electrode and the common electrode in each pixel unit of the liquid crystal display panel form a driving electric field, which can change the orientation of the liquid crystal molecules in the liquid crystal layer, thereby changing the polarization of the light passing through the liquid crystal layer. At this time, through the polarizing plates located on both sides of the liquid crystal display panel, each pixel unit can form a liquid crystal light valve, thereby realizing the display function. In addition, through the color filter on the counter substrate, the liquid crystal display panel can further realize color display.

[0005] In the liquid crystal display panel, in order to keep the thickness of the liquid crystal layer or the thickness of the liquid crystal cell uniform at different positions, a columnar spacer (referred to as a spacer) is generally arranged between the array substrate and the counter substrate. The spacer can support the liquid crystal cell, thereby keeping the thickness of the liquid crystal layer or the thickness of the liquid crystal cell stable and uniform. On the other hand, orientation layers are also arranged on both sides of the liquid crystal layer to arrange the liquid crystal molecules in the liquid crystal layer in a certain direction and angle. SUMMARY

[0006] Embodiments of the present disclosure provide a liquid crystal display panel and a display device. By improving the spacers in the first spacer pair and the second spacer pair, the liquid crystal display panel can effectively prevent the orientation layer on the array substrate and the counter substrate from being scratched, thereby effectively preventing light leakage and other defects. Moreover, the liquid crystal display panel does not need to increase the size of the black matrix, thereby also avoiding reducing the aperture ratio, which is conducive to realizing high resolution, high brightness, and low power consumption at the same time.

[0007] The liquid crystal display panel provided by at least one embodiment of the present disclosure includes an array substrate, an opposite substrate, a liquid crystal layer, an opposite substrate spacer, and an array substrate spacer. The opposite substrate is arranged opposite to the array substrate. The liquid crystal layer is located between the array substrate and the opposite substrate. The opposite substrate spacer is located on the opposite substrate. The array substrate spacer is located on the array substrate. The opposite substrate spacer includes a first spacer and a second spacer. The array substrate spacer includes a third spacer and a fourth spacer. The first spacer and the third spacer are arranged opposite and in contact in a first direction perpendicular to the array substrate to form a first spacer pair. The second spacer and the fourth spacer are arranged opposite and spaced in the first direction to form a second spacer pair. A height of the first spacer in the first direction is greater than a height of the third spacer in the first direction. A height of the second spacer in the first direction is greater than a height of the fourth spacer in the first direction. The height of the first spacer in the first direction is substantially equal to the height of the second spacer in the first direction. The height of the third spacer in the first direction is greater than the height of the fourth spacer in the first direction.

[0008] For example, in the liquid crystal display panel provided by an embodiment of the present disclosure, a difference between the height of the first spacer in the first direction and the height of the second spacer in the first direction is less than 0.2 microns.

[0009] For example, in the liquid crystal display panel provided by an embodiment of the present disclosure, the opposite substrate includes a first substrate, a first alignment layer, and a black matrix. The first substrate is located on a side close to the liquid crystal layer. The first spacer is located in the projection of the black matrix on the first substrate.

[0012] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, a height of the strip-shaped protruding structure in the first direction is greater than heights of the opening region of the first pixel structure and the opening region of the second pixel structure in the first direction and less than a height of an array substrate spacer arranged opposite to the opposing substrate spacer.

[0013] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, a projection of one of the opposing substrate spacers on the second substrate overlaps projections of at least two strip-shaped protruding structures on the second substrate.

[0014] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, the strip-shaped protruding structure further comprises a connecting part connecting the first bearing part and the second bearing part, the connecting part is located in the first interval region, and a projection of the connecting part on the second substrate overlaps a projection of the opposing substrate spacer on the second substrate.

[0015] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, a projection of one of the opposing substrate spacers on the second substrate overlaps projections of at least two strip-shaped protruding structures on the second substrate, and a projection of an array substrate spacer arranged opposite to the opposing substrate spacer on the second substrate overlaps projections of at least part of the at least two strip-shaped protruding structures on the second substrate.

[0016] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, the first bearing part is arranged in contact with the array substrate spacers opposite to the opposite substrate spacers near one end of the first spacing region.

[0017] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, the length of the first bearing part and the second bearing part in the third direction is greater than or equal to 20 microns.

[0018] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, the length of the first bearing part and the second bearing part in the third direction is greater than or equal to the length of one pixel structure in the third direction.

[0019] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, the material of the strip-shaped protruding structure comprises a conductive metal, each pixel structure comprises a pixel electrode and a common electrode, and the strip-shaped protruding structure is electrically connected to the common electrode.

[0020] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, the ratio of the sum of the areas of all the opposite substrate spacers near the surface of the array substrate to the area of the surface of the array substrate near the opposite substrate is greater than 3 / 100.

[0021] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, in the first pair of spacers, the first spacer extends in the third direction, the third spacer extends in the second direction, the two ends of the orthographic projection of the third spacer on the second substrate are respectively beyond the orthographic projection of the first spacer on the second substrate by a first distance and a second distance, and the first distance and the second distance are both greater than 15 microns.

[0022] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, in the second pair of spacers, the second spacer extends in the third direction, the fourth spacer extends in the second direction, the two ends of the orthographic projection of the fourth spacer on the second substrate are respectively beyond the orthographic projection of the second spacer on the second substrate by a third distance and a fourth distance, and the third distance and the fourth distance are both greater than 15 microns.

[0023] For example, in the liquid crystal display panel provided by the embodiment of the present disclosure, in the first pair of spacers, the first spacer is located in a second spacing region between the opening regions of two pixel structures adjacent in the second direction, and the third spacer extends from the second spacing region to the opening regions of the two pixel structures.

In the first type spacer pair, the first spacer extends along the third direction, the third spacer extends along the second direction, and one end of the orthogonal projection of the third spacer on the second substrate exceeds the first side of the orthogonal projection of the first spacer on the second substrate by a first distance. In the second type spacer pair, the first spacer extends along the third direction, the third spacer extends along the second direction, and one end of the orthogonal projection of the third spacer on the second substrate exceeds the second side of the orthogonal projection of the first spacer on the second substrate by a second distance. The first and second sides are opposite sides in the second direction, and the first and second distances are both greater than 15 microns.

[0048] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure.

[0049] Unless otherwise defined, technical or scientific terms used in the present disclosure should have the same meaning as commonly understood by one of ordinary skill in the art to which this present disclosure belongs. The terms "first", "second", and similar terms used in the present disclosure do not imply any order, quantity, or importance, but are used to distinguish different components. The terms "include", "contain", and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects.

[0050] In a liquid crystal display panel, the spacer plays a role in maintaining the thickness of the liquid crystal layer or the thickness of the liquid crystal cell uniform at different positions, and thus is very important in ensuring the stability and reliability of the product. On the other hand, the alignment layer plays a role in arranging the liquid crystal molecules in the liquid crystal layer in a certain direction and angle, and is also very important for the normal display of the liquid crystal display panel. If the alignment layer is scratched, the arrangement of the liquid crystal molecules will be disordered, resulting in light leakage and other defects.

[0051] During the assembly, transportation, and use of the liquid crystal display panel, if the liquid crystal display panel is subjected to strong external force, the array substrate and the opposing substrate are prone to misalignment, causing the position of the spacer to shift into the opening area of the pixel structure and scratch the alignment layer in the area, so that the arrangement of the liquid crystal molecules in the scratched area is disordered, and further light leakage and other defects occur.

[0052] Generally, to solve the above problems, the area scratched by the spacers can be shielded by the black matrix to avoid light leakage and other defects by increasing the size of the black matrix. However, this solution will reduce the aperture ratio of the liquid crystal display panel. Moreover, as the product size of the liquid crystal display panel increases, the size of the black matrix that needs to be increased or the margin for preventing light leakage that needs to be reserved is also increasing, thereby greatly reducing the aperture ratio of the liquid crystal display panel. A low aperture ratio of the liquid crystal display panel is not conducive to achieving high resolution, high brightness and low power consumption at the same time. On the other hand, the spacers can also be arranged in pairs, one spacer extending along a first direction and the other spacer extending along a second direction perpendicular to the first direction, so that after one spacer is offset, it is still located on the other spacer, avoiding scratching the alignment layer. However, due to the large size of the increased spacer in the other direction, it will invade the opening area of the pixel structure, which will also reduce the aperture ratio of the liquid crystal display panel and is not conducive to achieving high resolution, high brightness and low power consumption at the same time.

[0053] On the other hand, for large-size, high-brightness, high-resolution liquid crystal display panels (for example, a 32-inch, 16k resolution, 700 nit brightness liquid crystal display panel), the pitch between the pixel structures is only 6-12 microns, and the above two methods will make the aperture ratio of the product extremely low, and it is impossible to achieve high brightness, high resolution and low power consumption at the same time.

[0054] Fig. 1 is a partial plan view of a liquid crystal display panel according to the present disclosure; Fig. 2 is a cross-sectional view of a liquid crystal display panel according to the present disclosure; Fig. 3 is a schematic view of a misalignment of a liquid crystal display panel according to the present disclosure. As shown in Figs. 1 and 2, the liquid crystal display panel 10 includes an array substrate 11, a counter substrate 12, and a liquid crystal layer 13 between the array substrate 11 and the counter substrate 12; the array substrate 11 includes gate lines Gate, data lines Data, pixel structures 14, and an alignment layer 15; the counter substrate 12 includes a black matrix 16 and an alignment layer 17, and the area between two adjacent black matrices 16 and the light-emitting area of the pixel structure 14 itself define an actual effective light-emitting area; the alignment layer 15 of the array substrate 11 and the alignment layer 17 of the counter substrate 12 jointly act on the liquid crystal layer 13, so that the liquid crystal molecules in the liquid crystal layer 13 are arranged in a certain initial direction and initial angle. The plurality of gate lines Gate and the plurality of data lines Data can cross each other to define a plurality of pixel units, and each pixel unit can be provided with one of the pixel structures 14 described above. The liquid crystal display panel 10 further includes a spacer 18 between the array substrate 11 and the counter substrate 12. As shown in Figs. 2 and 3, if the array substrate 11 and the counter substrate 12 are misaligned due to external force, the position of the spacer 18 is shifted and enters the area where the pixel structure 14 is located and scratches the alignment layer 17 on the counter substrate 12. At this time, by increasing the size of the black matrix 16, the distance between the edge of the black matrix 16 and the edge of the spacer 18 is increased, so that the spacer 18 is still covered by the black matrix 16 even after the spacer 18 moves; the black matrix 16 can shield the area scratched by the spacer 18 to avoid light leakage and other defects. For example, due to different sizes of the liquid crystal display panel, the displacement of the array substrate and the counter substrate is different when subjected to external force. For a small-size liquid crystal display panel, the edge of the black matrix and the edge of the spacer need to be greater than 20 um; for a medium-size liquid crystal display panel, the edge of the black matrix and the edge of the spacer need to be greater than 30 um; and for a large-size liquid crystal display panel (such as a TV product), the edge of the black matrix and the edge of the spacer need to be greater than 50 um. However, as described above, referring to Fig. 2, increasing the size of the black matrix 16 will reduce the aperture ratio, which is not conducive to achieving high resolution, high brightness, and low power consumption at the same time.

[0055] Fig. 4 is a partial plan view of another liquid crystal display panel according to the present disclosure; Fig. 5 is a cross-sectional view of another liquid crystal display panel according to the present disclosure; and Fig. 6 is a schematic view of a misalignment of another liquid crystal display panel according to the present disclosure. As shown in Figs. 4 and 5, the liquid crystal display panel 10 includes an array substrate 11, a counter substrate 12, and a liquid crystal layer 13 between the array substrate 11 and the counter substrate 12; the array substrate 11 includes data lines Data, gate lines Gate, pixel structures 14, and an alignment layer 15; the counter substrate 12 includes a black matrix 16 and an alignment layer 17; a region between two adjacent black matrices 16 and a light-emitting region of the pixel structure 14 itself define an actual effective light-emitting region; the alignment layer 15 of the array substrate 11 and the alignment layer 17 of the counter substrate 12 jointly act on the liquid crystal layer 13, so that liquid crystal molecules in the liquid crystal layer 13 are arranged in a certain initial direction and initial angle. The plurality of gate lines Gate and the plurality of data lines Data can cross each other to define a plurality of pixel units, and each pixel unit can be provided with one of the pixel structures 14 described above. The liquid crystal display panel 10 further includes a pair of spacers 18 between the array substrate 11 and the counter substrate 12; the pair of spacers 18 includes first spacers 18A extending along a first direction and second spacers 18B extending along a second direction perpendicular to the first direction; that is, the first spacers 18A and the second spacers 18B are cross arranged. The first spacers 18A are located on the counter substrate 12 and are relatively fixed with the counter substrate 12, and the second spacers 18B are located on the array substrate 11 and are relatively fixed with the array substrate 11. As shown in Figs. 5 and 6, if the array substrate 11 and the counter substrate 12 are misaligned due to external force, the positions of the first spacers 18A on the counter substrate 12 are offset. At this time, since the first spacers 18A and the second spacers 18B are cross arranged, even if displacement occurs in the first direction or the second direction, the first spacers 18A and the second spacers 18B can still maintain contact, avoiding the first spacers 18A or the second spacers 18B from falling off, so that the first spacers 18A or the second spacers 18B can be prevented from entering the region where the pixel structure 14 is located and scratching the alignment layer. As shown in Figs. 5 and 6, although the first spacers 18A and the second spacers 18B described above are used, the size of the black matrix 16 can be reduced and does not need to occupy a large area, however, one of the cross arranged first spacers 18A and the second spacers 18B will invade the opening region of the pixel structure, thereby also reducing the aperture ratio, which is not conducive to simultaneously achieving high resolution, high brightness, and low power consumption.

[0056] In summary, according to the two embodiments shown in Figs. 1 to 6, whether by increasing the size of the black matrix or by arranging two cross arranged spacers, the aperture ratio of the liquid crystal display panel will be affected to varying degrees. A low aperture ratio of the liquid crystal display panel is not conducive to simultaneously achieving high resolution, high brightness, and low power consumption.

[0057] To this end, the present disclosure provides a liquid crystal display panel, comprising: an array substrate; an opposite substrate disposed opposite to the array substrate; a liquid crystal layer between the array substrate and the opposite substrate; an opposite substrate spacer on the opposite substrate; and an array substrate spacer on the array substrate; the opposite substrate spacer comprises a first spacer and a second spacer, the array substrate spacer comprises a third spacer and a fourth spacer, the first spacer and the third spacer are disposed opposite and in contact in a first direction perpendicular to the array substrate to form a first spacer pair, the second spacer and the fourth spacer are disposed opposite and spaced in the first direction to form a second spacer pair, a height of the first spacer in the first direction is greater than a height of the third spacer in the first direction, a height of the second spacer in the first direction is greater than a height of the fourth spacer in the first direction, the height of the first spacer in the first direction is substantially equal to the height of the second spacer in the first direction, and the height of the third spacer in the first direction is greater than the height of the fourth spacer in the first direction. Since the height of the first spacer on the opposite substrate in the first direction is greater than the height of the third spacer in the first direction, and the height of the second spacer on the opposite substrate in the first direction is greater than the height of the fourth spacer in the first direction, when the array substrate and the opposite substrate of the liquid crystal display panel are misaligned, the first spacer and the second spacer will be in contact with the array substrate, and the third spacer and the fourth spacer will be suspended and not in contact with the opposite substrate. Since the array substrate has a film layer such as a planarization layer formed thereon, the planarity of the array substrate is high, and when the first spacer and the second spacer are in contact with the array substrate with high planarity, the alignment layer on the array substrate is relatively less likely to be scratched. The third spacer and the fourth spacer are suspended and will not scratch the alignment layer on the opposite substrate. In addition, since the height of the first spacer in the first direction is substantially equal to the height of the second spacer in the first direction, and the height of the third spacer in the first direction is greater than the height of the fourth spacer in the first direction, when the array substrate and the opposite substrate of the liquid crystal display panel are misaligned, the first spacer and the second spacer will be in contact with the array substrate at the same time, thereby increasing the effective contact area and reducing the pressure on the alignment layer on the array substrate, which can effectively prevent the alignment layer on the array substrate from being scratched. Thus, by making the above-mentioned arrangement of the spacers in the first spacer pair and the second spacer pair, the liquid crystal display panel can effectively prevent the alignment layers on the array substrate and the opposite substrate from being scratched, thereby effectively preventing light leakage and other defects. Moreover, the liquid crystal display panel does not need to increase the size of the black matrix, thereby also avoiding reducing the aperture ratio, which is beneficial to achieving high resolution, high brightness and low power consumption at the same time.

[0058] The display device provided by the embodiments of the present disclosure can also prevent the alignment layer from being scratched when a large external force is applied, thereby avoiding light leakage and other defects. In addition, the display device can also achieve high resolution, high brightness and low power consumption at the same time.

[0059] The liquid crystal display panel and the display device provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0060] FIG. 7 is a schematic view of a partial cross-section of a liquid crystal display panel according to an embodiment of the present disclosure; and FIG. 8 is a schematic view of a liquid crystal display panel according to an embodiment of the present disclosure when the array substrate and the opposing substrate are misaligned.

[0061] As shown in FIGS. 7 and 8, the liquid crystal display panel 100 includes an array substrate 110, an opposing substrate 120 and a liquid crystal layer 130; the opposing substrate 120 is arranged opposite to the array substrate 110, and the liquid crystal layer 130 is located between the array substrate 110 and the opposing substrate 120. The liquid crystal display panel 100 further includes an opposing substrate spacer 140 and an array substrate spacer 150; the opposing substrate spacer 140 is arranged on the opposing substrate 120, and the array substrate spacer 150 is arranged on the array substrate 110. That is, the opposing substrate spacer 140 is fixed on the opposing substrate 120, and when the opposing substrate 120 moves, the opposing substrate spacer 140 will move with the opposing substrate 120; the array substrate spacer 150 is fixed on the array substrate 110, and when the array substrate 110 moves, the array substrate spacer 150 will move with the array substrate 110.

[0062] As shown in FIGS. 7 and 8, the opposing substrate spacer 140 includes a first spacer 141 and a second spacer 142; and the array substrate spacer 150 includes a third spacer 151 and a fourth spacer 152. It should be noted that the first spacer, the second spacer, the third spacer and the fourth spacer herein are used to represent different types of spacers; the opposing substrate spacer can include a plurality of first spacers and a plurality of second spacers, and the array substrate spacer can also include a plurality of third spacers and a plurality of fourth spacers.

[0063] As shown in FIGS. 7 and 8, the first spacers 141 and the third spacers 151 are oppositely and contactingly arranged in the first direction Z perpendicular to the array substrate 110 to form a first spacer pair 210; the first spacer 141 and the third spacer 151 in the first spacer pair 210 jointly function to maintain the liquid crystal layer 130. The second spacers 142 and the fourth spacers 152 are oppositely and spacedly arranged in the first direction Z to form a second spacer pair 220; the second spacer 142 and the fourth spacer 152 in the second spacer pair 220 jointly function to maintain the liquid crystal layer 130. Since the first spacer 141 and the third spacer 151 are oppositely and contactingly arranged in the direction perpendicular to the array substrate 110, the first spacer pair 210 here can also be regarded as a main spacer pair, i.e., a spacer pair that functions to mainly support. Since the second spacer 142 and the fourth spacer 152 are oppositely and spacedly arranged in the first direction Z, the second spacer pair 220 here can also be regarded as a sub spacer pair, i.e., a spacer pair that functions to secondarily support.

[0064] As shown in FIGS. 7 and 8, the height of the first spacer 141 in the first direction Z is greater than the height of the third spacer 151 in the first direction Z, and the height of the second spacer 142 in the first direction Z is greater than the height of the fourth spacer 154 in the first direction Z; the height of the first spacer 141 in the first direction Z is substantially equal to the height of the second spacer 142 in the first direction Z, and the height of the third spacer 151 in the first direction Z is greater than the height of the fourth spacer 152 in the first direction Z. It is to be noted that the height of each spacer in the first direction above is relative to the surface of the corresponding array substrate or the opposite substrate close to the liquid crystal layer, and the height of each spacer above can be the relative distance between the top end of each spacer and the surface of the corresponding array substrate or the opposite substrate close to the liquid crystal layer; if the spacers are on the same reference surface, the height of each spacer in the first direction above can also be the size of each spacer itself in the first direction. For example, the height of the first spacer in the first direction and the height of the second spacer in the first direction are relative to the surface of the opposite substrate close to the liquid crystal layer, and the height of the first spacer in the first direction and the height of the second spacer in the first direction can be the relative distance of the top end of the first spacer and the second spacer relative to the surface of the opposite substrate close to the liquid crystal layer; the height of the third spacer in the first direction and the height of the fourth spacer in the first direction are relative to the surface of the array substrate close to the liquid crystal layer, and the height of the third spacer in the first direction and the height of the fourth spacer in the first direction can be the relative distance of the top end of the third spacer and the fourth spacer relative to the surface of the array substrate close to the liquid crystal layer.

[0065] In the liquid crystal display panel provided in the embodiments of the present disclosure, the height of the first spacers on the opposing substrate in the first direction is greater than the height of the third spacers in the first direction, and the height of the second spacers on the opposing substrate in the first direction is greater than the height of the fourth spacers in the first direction. When the array substrate and the opposing substrate of the liquid crystal display panel are misaligned, the first spacers and the second spacers will be in contact with the array substrate, and the third spacers and the fourth spacers will be suspended and not in contact with the opposing substrate. Since the array substrate is provided with a film layer such as a planarization layer, the planarity of the array substrate is high. When the first spacers and the second spacers are in contact with the array substrate with high planarity, the force between the spacers on the opposing substrate and the alignment layer on the array substrate is small, and the alignment layer on the array substrate is relatively less likely to be scratched. The third spacers and the fourth spacers are suspended and will not scratch the alignment layer on the opposing substrate. In addition, the height of the first spacers in the first direction is substantially equal to the height of the second spacers in the first direction, and the height of the third spacers in the first direction is greater than the height of the fourth spacers in the first direction. When the array substrate and the opposing substrate of the liquid crystal display panel are misaligned, the first spacers and the second spacers will be in contact with the array substrate at the same time, thereby increasing the effective contact area and reducing the pressure on the alignment layer on the array substrate, and effectively preventing the alignment layer on the array substrate from being scratched. Thus, by arranging the spacers in the first spacer pair and the second spacer pair as described above, the liquid crystal display panel can effectively prevent the alignment layers on the array substrate and the opposing substrate from being scratched, thereby effectively preventing light leakage and other defects. Moreover, the liquid crystal display panel does not need to increase the size of the black matrix, thereby also avoiding reducing the aperture ratio, which is beneficial to achieving high resolution, high brightness and low power consumption at the same time.

[0066] In some examples, the height of the first spacers in the first direction and the height of the second spacers in the first direction are substantially equal, that is, the difference between the height of the first spacers in the first direction and the height of the second spacers in the first direction is less than 0.2 microns.

[0067] In some examples, as shown in FIGS. 7 and 8, in the first spacer pair 210, the first spacers 141 and the third spacers 151 are arranged opposite to and in contact with each other in a direction perpendicular to the array substrate 110; in the first spacer pair 220, the second spacers 142 and the fourth spacers 152 are arranged opposite to and spaced apart from each other in the first direction Z, and the distance between the second spacers 142 and the fourth spacers 152 can be in the range of 0.3-0.6 microns.

[0068] In some examples, as shown in FIGS. 7 and 8, the opposite substrate 120 described above includes the first substrate 121, the first alignment layer 191, and the black matrix 122; the first alignment layer 191 is located on the side of the first substrate 121 close to the liquid crystal layer 130. The orthogonal projection of the first spacers 141 on the first substrate 121 is within the orthogonal projection of the black matrix 122 on the first substrate 121, and the orthogonal projection of the second spacers 142 on the first substrate 121 is within the orthogonal projection of the black matrix 122 on the first substrate 121. Since the orthogonal projection of the first spacers 141 and the second spacers 142 on the first substrate 121 are both within the orthogonal projection of the black matrix 122 on the first substrate 121, and the first spacers 141 and the second spacers 142 are also arranged on the opposite substrate 120, the relative positional relationship between the black matrix 122 and the first spacers 141 and the second spacers 142 will not change, and the black matrix 122 will displace together with the first spacers 141 and the second spacers 142 even if the first spacers 141 and the second spacers 142 displace. In this case, even if the first spacers 141 and the second spacers 142 displace and scratch the alignment layer on the array substrate 110, the black matrix 122 can effectively shield the resulting light leakage.

[0069] In some examples, as shown in FIGS. 7 and 8, the array substrate 110 includes the second substrate 111, the second alignment layer 192, and a plurality of pixel structures 112; the second alignment layer 192 is located on the side of the second substrate 111 close to the liquid crystal layer 130, and the plurality of pixel structures 112 are arranged on the second substrate 111 along the second direction X and the third direction Y. Each pixel structure 112 includes an opening region 1120, the third spacers 151 are at least partially located between the opening regions 1120 of adjacent two pixel structures 112, and the fourth spacers 152 are at least partially located between the opening regions of adjacent two pixel structures 112. The opening region described above can also be regarded as the effective light-emitting region of each pixel structure. Thus, the third spacers 151 and the fourth spacers 152 arranged on the array substrate 110 will not affect the light-emitting display of each pixel structure 112.

[0070] It should be noted that the second direction and the third direction are also two directions located on a plane perpendicular to the first direction, and the second direction and the third direction intersect; in some examples, the second direction and the third direction can be perpendicular to each other.

[0071] In some examples, the ratio of the sum of the areas of all the opposing substrate spacers 140 near the surface of the array substrate 110 to the area of the surface of the array substrate 110 near the opposing substrate 120 in the liquid crystal display panel 100 is greater than 3 / 100. Thus, when the array substrate and the opposing substrate of the liquid crystal display panel are misaligned, the liquid crystal display panel can reduce the pressure of the opposing substrate spacers on the array substrate, thereby further reducing the possibility of the opposing substrate spacers scratching the alignment layer on the array substrate.

[0072] In some examples, to make the ratio of the sum of the areas of all the opposing substrate spacers 140 near the surface of the array substrate 110 to the area of the surface of the array substrate 110 near the opposing substrate 120 in the liquid crystal display panel greater than 3 / 100, the size of a single opposing substrate spacer can be increased, or the density of the opposing substrate spacers can be increased, which is not limited in the embodiments of the present disclosure. Of course, because the number of spacers is relatively fixed, increasing the size of a single opposing substrate spacer can effectively increase the ratio of the sum of the areas of all the opposing substrate spacers 140 near the surface of the array substrate 110 to the area of the surface of the array substrate 110 near the opposing substrate 120 in the liquid crystal display panel.

[0073] FIG. 9 is a partial schematic view of another liquid crystal display panel according to an embodiment of the present disclosure; FIG. 10 is a partial schematic view of an opposing substrate in a liquid crystal display panel according to an embodiment of the present disclosure; and FIG. 11 is a schematic view of the misalignment of an array substrate and an opposing substrate in another liquid crystal display panel according to an embodiment of the present disclosure.

[0074] As shown in FIGS. 9 and 10, the liquid crystal display panel 100 includes an array substrate 110, an opposing substrate 120, and a liquid crystal layer (not shown); it should be understood that the opposing substrate and the liquid crystal layer are omitted in FIG. 9 for better showing the structures on the array substrate 110; the relative positional relationship between the opposing substrate and the liquid crystal layer and the array substrate can be referred to FIG. 7 and the related description thereof.

[0075] As shown in FIGS. 9 and 10, the liquid crystal display panel 100 further includes opposing substrate spacers 140 and array substrate spacers 150, the opposing substrate spacers 140 are arranged on the opposing substrate 120, and the array substrate spacers 150 are arranged on the array substrate 110. That is, the opposing substrate spacers 140 are fixed on the opposing substrate 120, and when the opposing substrate 120 moves, the opposing substrate spacers 140 will move with the opposing substrate 120; the array substrate spacers 150 are fixed on the array substrate 110, and when the array substrate 110 moves, the array substrate spacers 150 will move with the array substrate 110.

[0076] As shown in FIG. 9 and FIG. 10, the opposing substrate spacers 140 are arranged opposite to the array substrate spacers 150, i.e., the orthographic projection of the opposing substrate spacers 140 on the array substrate 110 overlaps with the orthographic projection of the array substrate spacers 150 on the array substrate 110, so that the opposing substrate spacers 140 and the array substrate spacers 150 can form a pair of spacers and jointly support the liquid crystal layer. The height of the opposing substrate spacers 140 in the first direction Z is greater than the height of the array substrate spacers 150 in the first direction Z. It should be noted that the height of the above-mentioned opposing substrate spacers and array substrate spacers in the first direction is relative to the surface of the corresponding array substrate or opposing substrate close to the liquid crystal layer. The height of the above-mentioned opposing substrate spacers and array substrate spacers can be the relative distance between the top end of the opposing substrate spacers and array substrate spacers and the surface of the corresponding array substrate or opposing substrate close to the liquid crystal layer. If the opposing substrate spacers and array substrate spacers are at the same reference surface, the height of each of the above-mentioned opposing substrate spacers and array substrate spacers in the first direction can also be the size of the opposing substrate spacers and array substrate spacers in the first direction.

[0077] As shown in FIG. 9 and FIG. 10, the opposing substrate 120 includes a first substrate 121 and a black matrix 122; the orthographic projection of the opposing substrate spacers 140 on the first substrate 121 is located within the orthographic projection of the black matrix 122 on the first substrate 121; the array substrate 110 includes a second substrate 111 and a plurality of pixel structures 112; the plurality of pixel structures 112 are arranged on the second substrate 111 along the second direction X and the third direction Y. Each pixel structure 112 includes an opening region 1120.

[0078] It should be noted that the second direction and the third direction are also two directions in a plane perpendicular to the first direction, and the second direction and the third direction intersect; in some examples, the second direction and the third direction can be perpendicular to each other.

[0079] As shown in FIG. 9 and FIG. 10, the array substrate 110 further includes a strip-shaped protruding structure 115; the opposing substrate spacers 140 extend along the second direction X and are located in the first interval region 127A between the opening regions 1120 of two pixel structures 112 adjacent in the third direction Y, the two pixel structures 112 adjacent in the third direction Y include a first pixel structure 112A and a second pixel structure 112B. Since the pixel structures 112 on the array substrate 110 are arranged in an array, the opposing substrate spacers 140 can also be considered as being arranged in the first interval region 127A between two pixel structure rows adjacent in the third direction Y. The strip-shaped protruding structure 115 includes a first bearing portion 1151 and a second bearing portion 1152, a virtual connection of the first bearing portion 1151 and the second bearing portion 1152 has a normal projection on the second substrate 111 which overlaps a normal projection of the opposing substrate spacers 140 on the second substrate 111, the first bearing portion 1151 extends from the first interval region 127A to a side of the opening region of the first pixel structure 112A in the second direction X along the third direction Y, i.e. to a periphery of the opening region of the first pixel structure 112A, and the second bearing portion 1152 extends from the first interval region 127A to a side of the opening region of the second pixel structure 112B in the second direction X along the third direction Y, i.e. to a periphery of the opening region of the second pixel structure 112B.

[0080] In the liquid crystal display panel provided in this example, since the height of the opposing substrate spacers in the first direction is greater than the height of the array substrate spacers in the first direction, when the array substrate and the opposing substrate of the liquid crystal display panel are misaligned, the opposing substrate spacers will contact the array substrate, and the array substrate spacers will be suspended rather than contacting the opposing substrate; since the array substrate is provided with a film layer such as a planarization layer, the planarity of the array substrate is higher, when the opposing substrate spacers contact the array substrate with higher planarity, the force between the opposing substrate spacers and the alignment layer of the array substrate is smaller, and the alignment layer on the array substrate is less likely to be scratched; and the opposing substrate spacers are suspended, and the alignment layer on the opposing substrate is also not scratched.

[0081] On this basis, as shown in FIGS. 9-11, the array substrate 110 is further provided with a strip-shaped protruding structure 115, and a first bearing part 1151 of the strip-shaped protruding structure 115 extends from the first interval region 127A to one side of the opening region 1120 of the first pixel structure 112A in the third direction Y, and a second bearing part 1152 extends from the first interval region 127A to one side of the opening region 1120 of the second pixel structure 112B in the third direction Y. In this case, when the array substrate 110 and the counter substrate 120 of the liquid crystal display panel 100 are misaligned in the second direction X, the counter substrate spacers 140 will still fall into the second interval region 127B, which is not the opening region of the pixel structure 112, and a black matrix is usually provided for light shielding, thus having no adverse effect on the normal display and aperture ratio of the liquid crystal display panel; when the array substrate 110 and the counter substrate 120 of the liquid crystal display panel 100 are misaligned in the third direction Y, the counter substrate spacers 140 will slide onto the first bearing part 1151 or the second bearing part 1152 of the strip-shaped protruding structure 115, so as to prevent the counter substrate spacers 140 from contacting the alignment layer on the opening region 1120 of the pixel structure 112 on the array substrate 110, and thus effectively avoid scratching the alignment layer on the opening region 1120 of the pixel structure 112 by the counter substrate spacers 140. It should be noted that since the alignment layer is usually formed on the entire surface of the array substrate, the strip-shaped protruding structure can also have an alignment layer on the surface close to the liquid crystal layer, but the alignment layer is not located in the opening region of the pixel structure, thus having no adverse effect on the normal display of the pixel structure.

[0082] In some examples, the above-mentioned counter substrate spacers 140 can include the above-mentioned first spacers and second spacers; and the above-mentioned array substrate spacers 150 can include the above-mentioned third spacers and fourth spacers. In this case, the above-mentioned first spacers and second spacers can be defined by the structure and position of the above-mentioned counter substrate spacers, and the above-mentioned third spacers and fourth spacers can also be defined by the structure and position of the above-mentioned array substrate spacers.

[0083] In some examples, as shown in FIGS. 9-11, the above-mentioned strip-shaped protruding structure 115 is located in the second interval region 127B between two adjacent pixel structures 112 in the second direction X, so that the above-mentioned strip-shaped protruding structure 115 can be arranged by using the second interval region 127B. It should be noted that, as shown in FIG. 11, since the counter substrate spacers 140 themselves have a certain elasticity, when they slide onto the strip-shaped protruding structure 115, protruding parts 145 will be formed on both sides of the strip-shaped protruding structure 115.

[0084] In some examples, as shown in FIGS. 9-11, the height of the strip-shaped protruding structure 115 in the first direction Z is greater than the height of the opening region of the first pixel structure 112A and the opening region of the second pixel structure 112B in the first direction Z, and is less than the height of the array substrate spacer 150 opposite to the opposing substrate spacer 140. Thus, the strip-shaped protruding structure 115 can carry the opposing substrate spacer 140 after the opposing substrate spacer 140 slides off the array substrate spacer 150, and effectively protect the alignment layer on the opening region of the first pixel structure 112A and the opening region of the second pixel structure 112B.

[0085] In some examples, as shown in FIGS. 9-11, the orthogonal projection of one opposing substrate spacer 140 on the second substrate 111 overlaps with the orthogonal projection of the virtual connection of at least two strip-shaped protruding structures 115 on the second substrate 111. That is, at least two strip-shaped protruding structures 115 are provided corresponding to one opposing substrate spacer 140, so that when the opposing substrate spacer 140 slides onto the at least two strip-shaped protruding structures 115, the at least two strip-shaped protruding structures 115 can stably support the opposing substrate spacer 140.

[0086] For example, as shown in FIG. 9, the orthogonal projection of one opposing substrate spacer 140 on the second substrate 111 overlaps with the orthogonal projection of the virtual connection of four strip-shaped protruding structures 115 on the second substrate 111. Of course, the embodiments of the present disclosure include but are not limited to this.

[0087] In some examples, as shown in FIGS. 9-11, the strip-shaped protruding structure 115 further includes a connecting portion 1253 connecting the first carrying portion 1151 and the second carrying portion 1152, the connecting portion 1253 is located in the first interval region 127A, and the orthogonal projection of the connecting portion 1253 on the second substrate 111 overlaps with the orthogonal projection of the opposing substrate spacer 140 on the second substrate 111. That is, the strip-shaped protruding structure can be a disconnected structure including only the first carrying portion and the second carrying portion described above, or can be a continuous structure including the first carrying portion, the second carrying portion and the connecting portion described above. When the strip-shaped protruding structure includes the connecting portion described above, the virtual connection described above is located in the connecting portion.

[0088] In some examples, as shown in FIGS. 9-11, the orthogonal projection of the one opposing substrate spacer 140 on the second substrate 111 overlaps with the orthogonal projection of the at least two strip-shaped protrusion structures 115 on the second substrate 111, and the orthogonal projection of the array substrate spacer 150 opposite to the opposing substrate spacer 140 overlaps with the orthogonal projection of at least part of the at least two strip-shaped protrusion structures 115 on the second substrate 111. That is, when the strip-shaped protrusion structure is a continuous strip-shaped protrusion structure, part of the strip-shaped protrusion structure can pass through the array substrate spacer opposite to the opposing substrate spacer.

[0089] For example, as shown in FIGS. 9-11, the size of the opposing substrate spacer 140 in the second direction X is greater than the size of the array substrate spacer 150 in the second direction X, so the opposing substrate spacer 140 can cover four strip-shaped protrusion structures 115, and the array substrate spacer 150 only covers two strip-shaped protrusion structures 115. Of course, embodiments of the present disclosure include but are not limited to this, the size of the opposing substrate spacer in the second direction can also be equal to the size of the array substrate spacer in the second direction, and the size of the opposing substrate spacer in the second direction can also be less than the size of the array substrate spacer in the second direction.

[0090] In some examples, as shown in FIG. 9, the first bearing portion 1151 is arranged in contact with the array substrate spacer 150 opposite to the opposing substrate spacer 140 near one end of the first spacing region 127A, and the second bearing portion 1152 is arranged in contact with the array substrate spacer 150 opposite to the opposing substrate spacer 140 near one end of the first spacing region 127A. In this way, when the array substrate and the opposing substrate of the liquid crystal display panel are misaligned in the third direction Y, the opposing substrate spacer 140 can better slide from the corresponding array substrate spacer 150 to the first bearing portion 1151 or the second bearing portion 1152.

[0091] In some examples, as shown in FIG. 9, the length of the first bearing portion 1151 and the second bearing portion 1152 in the third direction Y is greater than or equal to 20 microns. In this way, the length of the first bearing portion and the second bearing portion is sufficient to bear the displaced opposing substrate spacer. Of course, since the strip-shaped protrusion structure is arranged in the second spacing region, the strip-shaped protrusion structure can also extend a longer distance in the third direction, for example, extending along the third direction in the entire display region.

[0092] In some examples, as shown in FIG. 9, the length of the first bearing portion 1151 and the second bearing portion 1152 in the third direction Y is greater than or equal to the length of one pixel structure 112 in the third direction Y. In this way, the length of the first bearing portion and the second bearing portion is sufficient to bear the displaced opposing substrate spacer, and is better compatible with the manufacturing process of the pixel structure.

[0093] In some examples, as shown in FIG. 9, the material of the strip-shaped protruding structure 115 includes a conductive metal, each pixel structure 112 includes a pixel electrode 1125 and a common electrode 1126, and the strip-shaped protruding structure 115 is electrically connected to the common electrode 1126. At this time, the strip-shaped protruding structure can reduce the load of the common electrode, so that the common voltage on the common electrode at different positions in the entire liquid crystal display panel is more uniform. It should be noted that the strip-shaped protruding structure itself can be reused as a common electrode line, or can be used as an auxiliary structure of the common electrode line.

[0094] In some examples, the ratio of the sum of the areas of all the opposing substrate spacers 140 close to the surface of the array substrate 110 to the area of the surface of the array substrate 110 close to the opposing substrate 120 in the liquid crystal display panel 100 is greater than 3 / 100. Thus, when the array substrate and the opposing substrate of the liquid crystal display panel are misaligned, the liquid crystal display panel can reduce the pressure of the opposing substrate spacers on the array substrate, thereby further reducing the possibility of the opposing substrate spacers scratching the alignment layer on the array substrate.

[0095] In some examples, in order to make the ratio of the sum of the areas of all the opposing substrate spacers close to the surface of the array substrate to the area of the surface of the array substrate close to the opposing substrate in the liquid crystal display panel greater than 3 / 100, the size of a single opposing substrate spacer can be increased, or the density of the opposing substrate spacers can be increased, which is not limited in the embodiments of the present disclosure. Of course, since the number of spacers is relatively fixed, increasing the size of a single opposing substrate spacer can effectively increase the ratio of the sum of the areas of all the opposing substrate spacers close to the surface of the array substrate to the area of the surface of the array substrate close to the opposing substrate in the liquid crystal display panel.

[0096] FIG. 12 is a partial schematic view of another liquid crystal display panel provided by an embodiment of the present disclosure; FIG. 13 is a partial schematic view of an opposing substrate in another liquid crystal display panel provided by an embodiment of the present disclosure; and FIG. 14 is a schematic view of the misalignment of an array substrate and an opposing substrate in another liquid crystal display panel provided by an embodiment of the present disclosure.

[0097] As shown in FIGS. 12 to 14, the liquid crystal display panel 100 includes an array substrate 110, an opposing substrate 120, and a liquid crystal layer (not shown); it should be understood that, in order to better show the structures on the array substrate 110, the opposing substrate and the liquid crystal layer are omitted in FIG. 12; the relative positional relationship between the opposing substrate and the liquid crystal layer and the array substrate can be referred to FIG. 7 and the related description thereof.

[0098] As shown in FIGS. 12 and 14, the liquid crystal display panel 100 further includes a counter substrate spacer 140 and an array substrate spacer 150, the counter substrate spacer 140 is disposed on the counter substrate 120, and the array substrate spacer 150 is disposed on the array substrate 110. That is, the counter substrate spacer 140 is fixed on the counter substrate 120, and when the counter substrate 120 moves, the counter substrate spacer 140 moves with the counter substrate 120; the array substrate spacer 150 is fixed on the array substrate 110, and when the array substrate 110 moves, the array substrate spacer 150 moves with the array substrate 110.

[0099] As shown in FIGS. 12 and 14, the counter substrate spacer 140 is disposed opposite to the array substrate spacer 150, that is, the orthographic projection of the counter substrate spacer 140 on the array substrate 110 overlaps the orthographic projection of the array substrate spacer 150 on the array substrate 110, so that the counter substrate spacer 140 and the array substrate spacer 150 can form a spacer pair and jointly support the liquid crystal layer. The height of the counter substrate spacer 140 in the first direction Z is greater than the height of the array substrate spacer 150 in the first direction Z. It should be noted that the height of the above-mentioned counter substrate spacer and array substrate spacer in the first direction is relative to the surface of the corresponding array substrate or counter substrate close to the liquid crystal layer, and the height of the above-mentioned counter substrate spacer and array substrate spacer can be the relative distance between the top end of the counter substrate spacer and array substrate spacer and the surface of the corresponding array substrate or counter substrate close to the liquid crystal layer; if the counter substrate spacer and the array substrate spacer are at the same reference surface, the height of each of the above-mentioned counter substrate spacer and array substrate spacer in the first direction can also be the size of the counter substrate spacer and array substrate spacer in the first direction.

[0100] As shown in FIGS. 12 and 14, the counter substrate 120 includes a first substrate 121 and a black matrix 122; the orthographic projection of the counter substrate spacer 140 on the first substrate 121 is located within the orthographic projection of the black matrix 122 on the first substrate 121; the array substrate 110 includes a second substrate 111 and a plurality of pixel structures 112; the plurality of pixel structures 112 are arranged on the second substrate 111 along the second direction X and the third direction Y. Each pixel structure 112 includes an opening region 1120.

[0101] It should be noted that the second direction and the third direction are also two directions in a plane perpendicular to the first direction, and the second direction and the third direction intersect; in some examples, the second direction and the third direction can be perpendicular to each other.

[0102] As shown in FIG. 12 and FIG. 14, the array substrate spacers 150 are located in the second interval regions 127B between the opening regions 120 of two pixel structures 112 adjacent in the second direction X. Since the pixel structures 112 are arranged in an array on the array substrate 110, the array substrate spacers 150 can also be regarded as being located between two pixel structure columns adjacent in the second direction X. In this case, the opposing substrate spacers 140 located opposite the array substrate spacers 150 are also located in the second interval regions 127B between the opening regions 120 of two pixel structures 112 adjacent in the second direction X. When the array substrate and the opposing substrate of the liquid crystal display panel are misaligned in the third direction Y, the opposing substrate spacers 140 slide off the array substrate spacers 150 and are still located in the second interval regions 127B, which does not adversely affect the normal display and aperture ratio of the liquid crystal display panel; when the array substrate and the opposing substrate of the liquid crystal display panel are misaligned in the second direction, the opposing substrate spacers slide off the array substrate spacers and are located in the opening regions of adjacent pixel structures, but since the array substrate has a high flatness and the opposing substrate spacers have a large contact area, the opposing substrate spacers can be prevented from scratching the alignment layer on the array substrate.

[0103] In some examples, the ratio of the sum of the areas of all the opposing substrate spacers 140 close to the surface of the array substrate 110 to the area of the surface of the array substrate 110 close to the opposing substrate 120 in the liquid crystal display panel 100 is greater than 3 / 100. Thus, when the array substrate and the opposing substrate of the liquid crystal display panel are misaligned, the liquid crystal display panel can reduce the pressure of the opposing substrate spacers on the array substrate, thereby further reducing the possibility of the opposing substrate spacers scratching the alignment layer on the array substrate.

[0104] In some examples, in order to make the ratio of the sum of the areas of all the opposing substrate spacers close to the surface of the array substrate to the area of the surface of the array substrate close to the opposing substrate greater than 3 / 100 in the liquid crystal display panel, the size of a single opposing substrate spacer can be increased, or the density of the opposing substrate spacers can be increased, which is not limited in the embodiments of the present disclosure.

[0105] In some examples, as shown in FIG. 12, the above-mentioned opposing substrate spacers 140 can include the above-mentioned first spacers 141 and the second spacers 142; the above-mentioned array substrate spacers 150 can include the above-mentioned third spacers 151 and the fourth spacers 152. The first spacers 141 and the third spacers 151 are oppositely and contiguously arranged in the first direction Z perpendicular to the array substrate 110 to form a first spacer pair 210; the first spacer 141 and the third spacer 151 in the first spacer pair 210 jointly function to maintain the liquid crystal layer 130. The second spacers 142 and the fourth spacers 152 are oppositely and spacedly arranged in the first direction Z to form a second spacer pair 220; the second spacer 142 and the fourth spacer 152 in the second spacer pair 220 jointly function to maintain the liquid crystal layer 130. Since the first spacers 141 and the third spacers 151 are oppositely and contiguously arranged in the direction perpendicular to the array substrate 110, the first spacer pair 210 here can also be regarded as a main spacer pair, i.e., a spacer pair that functions to mainly support. Since the second spacers 142 and the fourth spacers 152 are oppositely and spacedly arranged in the first direction Z, the second spacer pair 220 here can also be regarded as a sub spacer pair, i.e., a spacer pair that functions to secondarily support.

[0106] In this case, the above-mentioned first spacers and the second spacers can both be defined by the structure and position of the above-mentioned opposing substrate spacers, and the above-mentioned third spacers and the fourth spacers can also both be defined by the structure and position of the above-mentioned array substrate spacers.

[0107] In some examples, as shown in FIG. 12, the length of the above-mentioned opposing substrate spacers 140 in the third direction Y is substantially equal to the length of the corresponding array substrate spacers 150 in the third direction. Of course, the embodiments of the present disclosure include but are not limited to this, and the length of the above-mentioned opposing substrate spacers in the third direction can also be greater than or less than the length of the corresponding array substrate spacers in the third direction.

[0112] As shown in FIGS. 15 and 16, the opposed substrate spacer 140 is disposed opposite to the array substrate spacer 150, that is, the orthographic projection of the opposed substrate spacer 140 on the array substrate 110 overlaps with the orthographic projection of the array substrate spacer 150 on the array substrate 110, so that the opposed substrate spacer 140 and the array substrate spacer 150 can form a spacer pair and jointly support the liquid crystal layer. The height of the opposed substrate spacer 140 in the first direction Z is greater than the height of the array substrate spacer 150 in the first direction Z. It should be noted that the height of the above-mentioned opposed substrate spacer and array substrate spacer in the first direction is relative to the surface of the corresponding array substrate or opposed substrate close to the liquid crystal layer, and the height of the above-mentioned opposed substrate spacer and array substrate spacer can be the relative distance between the top end of the opposed substrate spacer and array substrate spacer and the surface of the corresponding array substrate or opposed substrate close to the liquid crystal layer; if the opposed substrate spacer and array substrate spacer are at the same reference surface, the height of each of the above-mentioned opposed substrate spacer and array substrate spacer in the first direction can also be the size of the opposed substrate spacer and array substrate spacer itself in the first direction.

[0113] As shown in FIGS. 15 and 16, the opposed substrate 120 includes a first substrate 121 and a black matrix 122; the orthographic projection of the opposed substrate spacer 140 on the first substrate 121 is located within the orthographic projection of the black matrix 122 on the first substrate 121; the array substrate 110 includes a second substrate 111 and a plurality of pixel structures 112; the plurality of pixel structures 112 are arrayed on the second substrate 111 along the second direction X and the third direction Y. Each pixel structure 112 includes an opening region 1120.

[0114] It should be noted that the second direction and the third direction are also two directions in a plane perpendicular to the first direction, and the second direction and the third direction intersect; in some examples, the second direction and the third direction can be perpendicular to each other.

The first spacer pair 210 here can also be regarded as a main spacer pair, i.e., a spacer pair that functions to mainly support. The second spacers 142 and the fourth spacers 152 are oppositely and spaced arranged in the first direction Z to form a second spacer pair 220.

Thus, when the array substrate and the opposing substrate of the liquid crystal display panel are misaligned in the second direction X, the first spacer 141 will still slide on the third spacer 151, so that the first spacer can be prevented from contacting the alignment layer on the array substrate.

[0118] As shown in FIG. 15, in the first spacer pair 210, the first spacer 141 is located in the second spacing region 127B between the opening regions 1120 of two pixel structures 112 adjacent in the second direction X, and the third spacer 151 extends from the second spacing region 127B to the opening regions 1120 of the two pixel structures 112. It should be noted that when the first spacer pair is applied to an ultra-high resolution product, the third spacer in the first spacer pair will have a certain impact on the aperture ratio, because the ultra-high resolution product does not have a black matrix or has a narrow black matrix in the second direction.

[0119] As shown in FIG. 15, in the second spacer pair 220, the second spacer 142 extends along the third direction Y, and the fourth spacer 152 extends along the third direction Y; that is, the second spacer pair does not adopt the above-mentioned cross design.

The height of the counter substrate spacer 140 in the first direction Z is greater than the height of the array substrate spacer 150 in the first direction Z.

[0125] As shown in FIGS. 17-19, the counter substrate 120 includes a first substrate 121 and a black matrix 122, and the orthographic projection of the counter substrate spacer 140 on the first substrate 121 is within the orthographic projection of the black matrix 122 on the first substrate 121.
