With the above technical solution, in a first aspect, the first pixel electrode of the first sub-pixel includes a plurality of first branch electrodes that are parallel to each other and electrically connected, that is, the first sub-pixel is a single-domain pixel structure; the second pixel electrode of the second sub-pixel comprises a plurality of second branch electrodes which are parallel to each other and electrically connected, namely the second sub-pixel is in a single-domain pixel structure; the third pixel electrode of the third sub-pixel comprises a plurality of third branch electrodes which are parallel to each other and electrically connected with each other and a plurality of fourth branch electrodes which are parallel to each other and electrically connected with each other, the extending direction of the third branch electrodes is different from the extending direction of the fourth branch electrodes, the third branch electrodes are in mirror symmetry with the row direction, and namely the third sub-pixel is in a double-domain pixel structure; when the attenuation rate of the display brightness of the first sub-pixel and the second sub-pixel is greater than that of the display brightness of the third sub-pixel, the display brightness of the third sub-pixel can be weaker than that of the first sub-pixel and the second sub-pixel by setting the third pixel electrode to be in a double-domain structure and setting the first pixel electrode and the second pixel electrode to be in a single-domain structure, so that the display brightness of the first sub-pixel, the second sub-pixel and the third sub-pixel can be enabled to be consistent under a large viewing angle, the problem of large viewing angle color cast can be improved, and the display effect of the display panel can be improved.

The above is the core idea of the present invention, and the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.

Fig. 1 is a schematic top-view structure diagram of a display panel according to an embodiment of the present invention, fig. 2 is a schematic top-view structure diagram of a pixel electrode according to an embodiment of the present invention, fig. 3 is a schematic film structure diagram of a display panel according to an embodiment of the present invention, and fig. 4 is a schematic top-view structure diagram of a liquid crystal molecule deflection direction according to an embodiment of the present invention. Referring to fig. 1 and 2 in combination, the plurality of sub-pixel columns of the display panel 100 includes a first sub-pixel column 10, a second sub-pixel column 20, and a third sub-pixel column 30. The first sub-pixel column 10 includes a plurality of first sub-pixels 11 sequentially arranged in a column direction Y, the second sub-pixel column 20 includes a plurality of second sub-pixels 21 sequentially arranged in the column direction Y, the third sub-pixel column 30 includes a plurality of third sub-pixels 31 sequentially arranged in the column direction Y, and display colors of the first sub-pixels 11, the second sub-pixels 21, and the third sub-pixels 31 are different from each other. The first sub-pixel 11 includes a first pixel electrode 110, and the first pixel electrode 110 includes a plurality of first branch electrodes 111 parallel to each other and electrically connected to each other, that is, the first sub-pixel 11 is a single-domain pixel structure; the second sub-pixel 21 comprises a second pixel electrode 210, and the second pixel electrode 210 comprises a plurality of second branch electrodes 211 which are parallel to each other and electrically connected, that is, the second sub-pixel 21 has a single-domain pixel structure; the third sub-pixel 31 comprises a third pixel electrode 310, the third pixel electrode 310 comprises a plurality of third branch electrodes 311 parallel to and electrically connected to each other and a plurality of fourth branch electrodes 312 parallel to and electrically connected to each other, and the third branch electrodes and the fourth branch electrodes extend in different directions and are mirror-symmetric with respect to the row direction X, i.e. the third sub-pixel 31 is a two-domain pixel structure.

With continuing combined reference to fig. 1 and fig. 2, the extending direction of the first branch electrode 111 of the first pixel electrode 110 and the extending direction of the second branch electrode 211 of the second pixel electrode 210 in the same row are different and mirror-symmetrical with respect to the column direction Y; the extending directions of the first branch electrodes 111 of any two adjacent first sub-pixels 11 in the same column are different and are mirror-symmetrical with respect to the row direction X; the second branch electrodes 211 of any two adjacent second sub-pixels 21 in the same column extend in different directions and are mirror-symmetrical with respect to the row direction X.

Referring to fig. 1 and 3 In combination, the display panel 100 may be a Twisted Nematic (TN) liquid crystal display panel, an In-Plane Switching (IPS) liquid crystal display panel, a Fringe Field Switching (FFS) liquid crystal display panel, or the like. Taking the display panel 100 as an IPS liquid crystal display panel as an example, the display panel 100 may include an array substrate 101 and an opposite substrate 102 disposed opposite to the array substrate 101, and a liquid crystal layer 103 between the array substrate 101 and the opposite substrate 102, the liquid crystal layer including liquid crystal molecules 1031. The array substrate 101 includes a substrate 1011, and a common electrode 1013 and a pixel electrode 1012 located on one side of the substrate 1011 close to the opposite substrate 102, and an insulating layer 1014 is located between the pixel electrode 1012 and the common electrode 1013; the opposite substrate 102 includes a substrate 1021 as a black matrix 1022 and

color resist patterns

120, 220, and 320 located at a side of the substrate 1021 near the array substrate 101. When a voltage is applied to each of the pixel electrode 1012 and the common electrode 1013, an electric field is generated due to a voltage difference between the pixel electrode 1012 and the common electrode 1013, and the generated electric field can drive the liquid crystal molecules 1031 of the liquid crystal layer 103 to deflect in-plane so that light can pass through the liquid crystal layer to reach the counter substrate 102, and different colors can be displayed after passing through the

color resist patterns

120, 220, and 320 of the counter substrate 102. Wherein the angle of deflection of the liquid crystal molecules 1031 is related to the direction of the electric field.

Referring to fig. 2 and 4 in combination, when the extension directions of the branch electrodes of two adjacent pixel electrodes are different, the directions of the electric fields generated by the two adjacent pixel electrodes are different, so that the deflection directions of the liquid crystal molecules in the corresponding regions of the two adjacent pixel electrodes are different. The extending directions of the first branch electrodes 111 of the first pixel electrodes 110 and the second branch electrodes 211 of the second pixel electrodes 210 in the same row are different and are mirror-symmetric with respect to the column direction Y, resulting in different directions of the electric fields generated by the first pixel electrodes 110 and the second pixel electrodes 210 in the same row, so that the liquid crystal molecules 1031 in the regions corresponding to the first pixel electrodes 110 and the liquid crystal molecules 1031 in the regions corresponding to the second pixel electrodes 210 in the same row can have mirror-symmetric deflection directions; the extending directions of the first branch electrodes 111 of two adjacent first pixel electrodes 110 in the same column are different and are mirror-symmetric with respect to the row direction X, resulting in different directions of the electric fields generated by two adjacent first pixel electrodes 110 in the same column, so that the liquid crystal molecules 1031 in the regions corresponding to two adjacent first pixel electrodes 110 in the same column can have mirror-symmetric deflection directions; the extending directions of the second branch electrodes 211 of two adjacent second pixel electrodes 210 in the same column are different and are mirror-symmetric with respect to the row direction X, which results in that the directions of the electric fields generated by two adjacent second pixel electrodes 210 in the same column are different, so that the liquid crystal molecules 1031 in the regions corresponding to two adjacent second pixel electrodes 210 in the same column can have mirror-symmetric deflection directions; in this way, the deflection directions of the liquid crystal molecules 1031 in the respective regions corresponding to the adjacent pixel electrodes are different, so that the brightness of the light propagating in the respective directions after passing through the liquid crystal layer 103 tends to be the same, the display brightness of the display images viewed in the respective directions of the display panel can tend to be the same, and the display images with the display brightness tending to be the same can be particularly viewed on the two opposite sides of the display panel, thereby being beneficial to improving the display effect of the display panel. Illustratively, when the display panel is applied to a center control panel of an in-vehicle display, the brightness of a display screen viewed by a main driving position and the brightness of a display screen viewed by a secondary driving position can be made to be approximately consistent.

With continuing reference to fig. 1, fig. 2, fig. 3 and fig. 4, the color-resisting pattern 120 opposite to the first pixel electrode 110 may be a red color-resisting pattern or a green color-resisting pattern, i.e. the display color of the first sub-pixel 11 is red or green; the color resistance pattern 220 opposite to the second pixel electrode 210 can be a green color resistance pattern or a red color resistance pattern, that is, the display color of the second sub-pixel 21 is green or red; the color resistance pattern 320 opposite to the third pixel electrode 310 may be a blue color resistance pattern, i.e., the display color of the third sub-pixel 31 is blue; wherein the display colors of the first sub-pixel 11 and the second sub-pixel are different. For convenience of description, the embodiment of the present invention is described by taking the display color of the first sub-pixel 11 as red and the display color of the second sub-pixel as blue as an example.

Since the display luminance of the sub-pixels with different display colors will have different decay rates with the increase of the viewing angle, and when the display color of the first sub-pixel 11 is red, the display color of the second sub-pixel 21 is green, and the display color of the third sub-pixel 31 is blue, the decay rate of the display luminance of the first sub-pixel 11 and the second sub-pixel 21 is greater than that of the third sub-pixel 31; meanwhile, the deflection angle of the liquid crystal molecules 1031 of the liquid crystal layer 103 is related to the electric field direction, and the deflection angle of the liquid crystal molecules 1031 at the position where the electric field distribution is disordered may be disordered. Therefore, when the first pixel electrode 110 and the second pixel electrode 120 are both in a single-domain structure, and the third pixel electrode 310 is in a double-domain structure, the electric field direction of the region corresponding to the third branch electrode 311 in the third pixel electrode 310 is different from the battery direction of the region corresponding to the fourth branch electrode 312, so that the region corresponding to the boundary between the third branch electrode 311 and the fourth branch electrode 312 generates an electric field with disordered distribution, which causes the liquid crystal molecules 1031 at the boundary between each third branch electrode 311 and each fourth branch electrode 312 to be arranged in disorder, so as to form an optical relatively dark region at the boundary between each third branch electrode 311 and each fourth branch electrode 312, and the optical dark region does not occur in the region corresponding to the first pixel electrode 110 and the second pixel electrode 210 in the single-domain structure, so that the display brightness of the third sub-pixel 31 is weaker than the display brightness of the first sub-pixel 11 and the second sub-pixel 21 as a whole, therefore, under a large viewing angle, the display brightness of the first sub-pixel 11, the second sub-pixel 21 and the third sub-pixel 31 can be made to be consistent, so as to improve the color cast problem of the large viewing angle and improve the display effect of the display panel 100.

It should be noted that, in the embodiment of the present invention, the display colors of the first sub-pixel 11, the second sub-pixel 21, and the third sub-pixel 31 are different from each other, and therefore, the display colors of the first sub-pixel 11, the second sub-pixel 21, and the third sub-pixel 31 are not limited thereto.

Optionally, fig. 5 is a schematic top view structure diagram of another display panel provided in an embodiment of the present invention. The same in fig. 5 as in fig. 1 can be referred to the description of fig. 1, and only the differences in fig. 5 from fig. 1 are exemplarily described here. As shown in fig. 5, the display panel 100 may further include a sub-pixel 302 with a white display color. The sub-pixel 302 with the white color and the sub-pixel 301 with the blue color are both located in the third sub-pixel column 30, and the sub-pixel 302 with the white color and the sub-pixel 301 with the blue color are arranged at an interval. In this way, the display luminance of the display panel 100 can be improved, the display effect of the display panel 100 can be further improved, and the requirement of the display luminance under a large viewing angle can be met. On the premise that the display luminance of the display panel 100 can be improved, the size of the sub-pixel 302 with the display color of white may be smaller than the size of the sub-pixel 301 with the display color of blue.

In the Y direction, the length of the third subpixel 302 displaying the color white is a first length, the length of the third subpixel 301 displaying the color blue is a second length, and the lengths of the first subpixel 11 and the second subpixel 21 are a third length. When the size of the third subpixel 302 displaying the color white is smaller than that of the subpixel 301 displaying the color blue, the first length may be smaller than the second length, and the second length may be smaller than the third length. At this time, the data lines 42 in the display panel 100 may be disposed between two adjacent columns of sub-pixels, the gate lines 41 may be disposed between two adjacent rows of sub-pixels, and the gate lines 41 need to be routed accordingly.

For convenience of description, the following description will exemplarily explain the technical solution of the embodiment of the present invention by taking the same size of each sub-pixel in the third sub-pixel column 30 of the display panel 100 as an example.

Optionally, fig. 6 is a schematic structural diagram of a branch electrode according to an embodiment of the present invention. Referring to fig. 2 and 6 in combination, in the same row, the first branch electrode 111 of the first pixel electrode 110 and the second branch electrode 211 of the second pixel electrode 210 are mirror-symmetric with respect to the column direction Y, so that the first branch electrode 111 of the first pixel electrode 110 and the second branch electrode 211 of the second pixel electrode 210 have the same angle with the row direction X. An acute angle between the extending direction of the first branch electrode 111 and the row direction X and an acute angle between the extending direction of the second branch electrode 211 and the row direction X are both θ; wherein, the value range of theta is as follows: theta is more than or equal to 7 degrees and less than or equal to 13 degrees.

In this way, on one hand, the liquid crystal molecules corresponding to the areas where the first pixel electrode 110 and the second pixel electrode 210 are located can have deflection in all directions, and the display panel has display consistency in all directions; on the other hand, since the deflection direction of the liquid crystal molecules is related to the extension direction of the branch electrodes, when the acute angle between the extension direction of the first branch electrode 111 and the row direction X and the acute angle θ between the extension direction of the second branch electrode 211 and the row direction X are set to be equal to or greater than 7 ° and equal to or less than 13 °, a relatively high transmittance of light passing through the liquid crystal layer can be ensured, and meanwhile, the response rate of the liquid crystal molecules during one-frame display can be ensured, so that the phenomenon of smear caused by the liquid crystal molecules not being deflected in place can be prevented, and the display effect of the display panel can be further improved.

Optionally, fig. 7 is a schematic top view structure diagram of another pixel electrode according to an embodiment of the present invention. As shown in fig. 7, the first pixel electrode 110 and the second pixel electrode 122 located in the same row are mirror-symmetric with respect to the third subpixel; any adjacent two first pixel electrodes 110 located in the same column are mirror-symmetrical, and any adjacent two second pixel electrodes 120 located in the same column are mirror-symmetrical.

Illustratively, a plurality of first branch electrodes 111 parallel to each other in the first pixel electrode 110 may be electrically connected together by a first connection part 112, so that an electrical signal applied to the first pixel electrode 110 can be transmitted to each of the first branch electrodes 111; a plurality of second branch electrodes 211 parallel to each other in the second pixel electrode 210 may be electrically connected together through a second connection part 212, so that an electrical signal applied to the second pixel electrode 210 can be transmitted to each of the second branch electrodes 211. At this time, when the first pixel electrode 110 and the second pixel electrode 210 in the same row are mirror-symmetrical with respect to the third sub-pixel, the first branch electrode 111 of the first pixel electrode 110 and the second branch electrode 211 of the second pixel electrode 210, and the first connection portion 112 in the first pixel electrode 110 and the second connection portion 212 in the second pixel electrode 210 are mirror-symmetrical with respect to the third sub-pixel; when two adjacent first pixel electrodes 110 in the same column are mirror-symmetrical, the first branch electrode 111 and the first connection portion 112 in the two mirror-symmetrical first pixel electrodes 110 are mirror-symmetrical; when two adjacent second pixel electrodes 210 in the same column are mirror-symmetrical, the second branch electrode 211 and the second connection portion 212 of the mirror-symmetrical second pixel electrode 210 are mirror-symmetrical. Therefore, when the display panel is respectively positioned at two opposite sides of the display panel, a display picture with consistent display brightness and display effect can be observed. When the display panel is applied to the central control screen for vehicle-mounted display, the main driving position and the assistant driving position are respectively positioned at two opposite sides of the central control screen, so that the display brightness and the display effect of display pictures viewed by the main driving position and the assistant driving position are kept consistent, and the display effect of the display panel is further improved.

In addition, the plurality of third branch electrodes 311 parallel to each other and the plurality of fourth branch electrodes 312 parallel to each other in the third pixel electrode 310 of the third sub-pixel may be electrically connected together through the third connection portion 313, so that an electrical signal applied to the third pixel electrode 310 can be transmitted to each of the third branch electrodes 311 and each of the fourth branch electrodes 312, respectively.

Optionally, fig. 8 is a schematic top view structure diagram of an outline of a pixel electrode according to an embodiment of the present invention. With reference to fig. 7 and 8, the peripheral outlines of the first pixel electrode 110 and the second pixel electrode 210 are both parallelogram, and the peripheral outline of the third pixel electrode 310 is rectangular; the outer contour of the first pixel electrode 110 includes a first side a1 parallel to the row direction X, and a second side b1 disposed obliquely to the column direction Y; the outer contour of the second pixel electrode 210 includes a third side a2 parallel to the row direction X, and a fourth side b2 disposed obliquely to the column direction Y; the rectangular sides a3 and b3 of the outer periphery of the third pixel electrode 310 are parallel to the row direction X and the column direction Y, respectively.

Specifically, when the second side b1 of the first pixel electrode 110 is disposed obliquely with respect to the column direction Y, the fourth side b2 of the second pixel electrode 210 is disposed obliquely with respect to the column direction Y, and the rectangular side b3 of the third pixel electrode 310 is not disposed obliquely, traces, thin film transistors, fingerprint identification elements, and the like may be disposed in the gap between the first pixel electrode 110 and the third pixel electrode 310, the gap between the third pixel electrode 310 and the second pixel electrode, and the gap between the first pixel electrode 110 and the second pixel electrode. Compared with the situation that the first pixel electrode and the second pixel electrode are rectangular, the oblique edges of the first pixel electrode and the second pixel electrode in the parallelogram can enable the gap width between the pixel electrodes to gradually change along the column direction, and when the routing lines, the thin film transistors, the fingerprint identification elements and the like are arranged at the positions with larger gap widths, the aperture opening ratio of the display panel is favorably improved, so that the display effect of the display panel is favorably improved.

The value ranges of the acute angle included angle between the second side b1 and the column direction Y and the acute angle included angle α between the fourth side b2 and the column direction Y are as follows: alpha is more than or equal to 4 degrees and less than or equal to 8 degrees. Therefore, on the premise that the regions where the first pixel electrode 110 and the second pixel electrode 210 are located have high transmittance, the liquid crystal molecules corresponding to the regions where the first pixel electrode 110 and the second pixel electrode 210 are located have high response rate, so that the display effect of the display panel is improved.

With continuing reference to fig. 9 and 10, the first sub-pixels 11 in the same row share a gate line, that is, the first pixel electrodes 1101 (or 1102) of the first sub-pixels 11 in the same row can be electrically connected to the same gate line 412 (or 413) through the corresponding first switches 1201 (or 1202); the second sub-pixels 21 in the same row share the gate line, that is, the second pixel electrodes 2101 (or 2102) of the second sub-pixels 21 in the same row can be electrically connected to the same gate line 411 (or 412) through the corresponding second switches 2201 (or 2202); the third sub-pixels 31 in the same row share a gate line, that is, the third pixel electrodes 3101 (or 3102) of the third sub-pixels 31 in the same row can be electrically connected to the same gate line 412 (or 413) through the corresponding third switches 3201 (or 3202), and the first sub-pixel 11 and the third sub-pixel 31 in the same row share a gate line 412 (or 413). Meanwhile, two adjacent

first pixel electrodes

1101 and 1102 in the same column are electrically connected to two

adjacent data lines

421 and 422 through

first switches

1201 and 1202, respectively; two

second pixel electrodes

2101 and 2102 adjacent to each other in the same column are electrically connected to two

adjacent data lines

424 and 423 through

second switches

2201 and 2202, respectively; and each of the

third pixel electrodes

3101 and 3102 in the same column is electrically connected to the data line 422 through the

third switches

3201 and 3202, respectively.

With continued combined reference to fig. 9 and 10, in the pixel group 50, the first pixel electrode 1101 of the first pixel 511 is inclined to the side of the first pixel electrode 1101 close to the third pixel electrode 3101, and the first pixel electrode 1102 of the second pixel 521 is inclined to the side far from the third pixel electrode 3102, so that the gap between the four pixel electrodes of the

first pixel electrodes

1101 and 1102 and the

third pixel electrodes

3101 and 3102 has a larger reserved space, i.e., the gap between the column in which the first sub-pixel 11 is located and the column in which the third sub-pixel 31 is located, and the intersection of the gap between the adjacent first pixel 511 and the second pixel 521 in the pixel group 50 has a larger-sized non-open region, which is the first position. The thin film transistor 1201 of the first sub-pixel in the first pixel 511 and the thin film transistor 3201 of the third sub-pixel in the first pixel 511 are both disposed at the first position. In this way, after the first pixel electrode 1101 is obliquely disposed, the non-opening area around the first pixel electrode 1101 can be effectively used, so that the thin film transistor 1201 and the thin film transistor 3201 are not provided to affect the opening ratio of the display panel 100, which is advantageous for improving the opening ratio of the display panel 100.

Accordingly, the gap on the side of the first pixel electrode 1102 of the second pixel 521 far from the first pixel electrode 1101 of the first pixel 511 is a first gap, the gap on the side of the first pixel electrode 1102 of the second pixel 521 far from the third pixel electrode 3102 of the second pixel 521 is a second gap, and a reserved space with a larger area is formed at the position where the first gap and the second gap intersect, that is, the gap between the first sub-pixel 1102 of the second pixel 521 and the three pixel groups 50 adjacent to the first sub-pixel 1102 has a non-opening area with a larger size, and the non-opening area is a third position. By disposing the tft 1202 of the first sub-pixel in the second pixel 521 at the third position, the non-open area around the first pixel electrode 1102 can be effectively utilized after the first pixel electrode 1102 is disposed in an inclined manner, so that the aperture ratio of the display panel 100 is not affected by the tft 1202, which is beneficial to improving the aperture ratio of the display panel 100.

Meanwhile, the second pixel electrode 2101 in the first pixel 511 is inclined to the side of the second pixel electrode 2101 close to the third pixel electrode 3101, and the second pixel electrode 2102 in the second pixel 521 is inclined to the side far from the third pixel electrode 3102, so that the gap between the four

pixel electrodes

2101 and 2102 and the

third pixel electrodes

3101 and 3102 has a large reserved space, that is, the gap between the column in which the second subpixel 21 in the second pixel 521 is located and the column in which the third subpixel 31 in the second pixel 521 is located, and the intersection of the gap between the adjacent first pixel 511 and the second pixel 521 in the pixel group 50 has a large-sized non-open region, which is a fifth position. The thin film transistor 2202 of the second sub-pixel in the second pixel 521 is disposed at the fifth position. In this way, after the second pixel electrode 2102 is obliquely disposed, the non-open area around the second pixel electrode 2102 can be effectively utilized, so that the aperture ratio of the display panel 100 is not affected by the arrangement of the thin film transistor 2202, which is further beneficial to improving the aperture ratio of the display panel 100.

Accordingly, the gap at the side of the second pixel electrode 2101 of the first pixel 511 far from the second pixel electrode 2102 of the second pixel 521 is a third gap, the gap at the side of the second pixel electrode 2101 of the first pixel 511 far from the third pixel electrode 3101 of the first pixel 511 is a fourth gap, and a reserved space with a larger area is also formed at the intersection position of the third gap and the fourth gap, that is, a non-opening area with a larger size is formed at the gap between the second subpixel 2101 in the first pixel 511 and the three pixel groups 50 adjacent to the second subpixel 2101, and the non-opening area is a second position. Wherein the thin film transistor 2201 of the second sub-pixel in the first pixel 511 is disposed at the second position. In this way, after the second pixel electrode 2101 is obliquely disposed, the non-opening area around the second pixel electrode 2101 can be effectively used, so that the aperture ratio of the display panel 100 is not affected by the provision of the thin film transistor 2201, which is advantageous for improving the aperture ratio of the display panel 100.

In addition, in order to satisfy the requirement that the data signal line is shared by the third subpixels of the same column, the thin film transistor 3201 of the third subpixel of the second pixel 521 may be disposed at a fourth position. Wherein the fourth position is: the intersection of the gap between the first subpixel 1102 in the second pixel 521 and the third subpixel 3102 in the second pixel 521, and the gap between the pixel group 50 adjacent to the third subpixel 3102.

The orthographic projection of the auxiliary supporting column 62 on the substrate base plate 1011 is positioned in the gap between two adjacent sub-pixels; and the orthographic projection of the auxiliary supporting column 62 on the substrate base plate 1011 does not overlap with the orthographic projection of the main supporting column 61, the first pixel electrode 110, the second pixel electrode 210 and the third pixel electrode 310 on the substrate base plate 1011.

For example, the auxiliary supporting pillars 62 may be disposed in the gaps between two adjacent sub-pixels in the same pixel group 50; alternatively, when the main support post 61 is not disposed at the gap position surrounded by the pixel group 501, the pixel group 502, the pixel group 503, and the pixel group 504, the auxiliary support posts 62 may be disposed at the gap position surrounded by the pixel group 501, the pixel group 502, the pixel group 503, and the pixel group 504, so that the arrangement positions of the auxiliary support posts 62 and the main support posts 61 may be prevented from being collided, and the aperture ratio of the display panel 100 may be improved.

Wherein, the value of n, which is the ratio of the number of the auxiliary supporting columns 62 in the display panel 100 to the number of the sub-pixels in the display panel, can be 14/18-33/18. Thus, the auxiliary supporting posts 62 assist the main supporting posts 61 to support the display panel 100, so that the display effect of the display panel 100 can be improved by preventing the display panel 100 from being damaged by the auxiliary supporting posts 62 while the aperture ratio of the display panel 100 is affected.
