Description

Technical Field

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

[0002] As people have higher and higher requirements for the cost and thinness of display screens, some thicker film layers have to be removed to make the display panel meet certain cost and thickness requirements, such as the planarization layer on the array substrate.

[0003] The planarization layer on the array substrate is used to planarize the thin-film transistors or signal wiring. The surface of the array substrate is uneven due to the patterning of the relevant film layer. When the planarization layer is deleted, the surface of the array substrate in the signal wiring area is convex, and the surface of the signal wiring area is relatively concave, and the signal wiring area is relatively small. The signal wiring line width is small, so the area of ​​the protruding area is also relatively small. In order to prevent the signal wiring from reflecting light, the display panel usually sets a black matrix above the signal wiring for shading, and usually sets the support column for supporting the display panel in the area where the signal wiring is located. Because the liquid crystal molecules around the support column are easily squeezed to produce light leakage, this design can simultaneously use the black matrix located above the signal wiring to shield the area where the support column is located, thereby minimizing the area shielded by the black matrix and increasing the light emitting area of ​​the display panel. If the area of ​​the protruding area where the signal routing is located is too large, the support column and the protruding area of ​​the signal routing will be displaced when the display panel is impacted by external force, so that the support column and the protruding area of ​​the signal routing cannot be aligned with each other, resulting in insufficient supporting force for the display panel, and further making the thickness of the liquid crystal layer formed at different positions between the array substrate and the opposing substrate uneven. Light passing through liquid crystal layers of different thicknesses will form different optical path differences, thereby affecting the uniformity of light output and possibly causing light leakage; even if the display panel is not impacted by external force, due to the alignment deviation between the signal routing and the support column itself, the relative position relationship between the support columns and the signal routing in different areas is inconsistent, that is, the support columns in some areas may be aligned with the protruding areas of the signal routing, while the support columns in some areas may slip and fail to support the protruding areas of the signal routing, which will also cause insufficient supporting force for the display panel and affect the uniformity of light output.

[0004] Therefore, how to achieve good support for the display panel of the de-planarization layer while ensuring that the display panel has a relatively high light output area, that is, to ensure its aperture ratio and achieve a higher brightness display, is a problem that urgently needs to be solved by technical personnel in this field. Summary of the invention

[0005] In view of this, an embodiment of the present invention provides a display panel and a display device, wherein the display panel can form a good support and ensure that the display panel has a high brightness.

[0006] In a first aspect, the present invention provides a display panel, comprising:

[0007] An array substrate and a color filter substrate are arranged opposite to each other, and a support column is located between the array substrate and the color filter substrate, wherein the support column includes a main support column, the main support column is arranged on one side of the array substrate and abuts against the surface of the color filter substrate, or the main support column is arranged on one side of the color filter substrate and abuts against the surface of the array substrate, and the main support column includes a first support column;

[0008] The array substrate includes a metal portion, and a projection of the first support column in a direction perpendicular to the plane where the display panel is located is at least partially surrounded by a projection of the metal portion in a direction perpendicular to the plane where the display panel is located.

[0009] In a second aspect, the present invention further provides a display device, which includes the display panel described in the first aspect.

[0010] The display panel provided by the present invention, by at least partially surrounding at least part of the main support columns in the main support columns with the metal part on the array substrate, on the one hand, does not need to significantly move the setting position of the main support columns, which is conducive to reusing the black matrix above the metal part to shield the metal part and the main support columns at the same time, thereby avoiding light leakage caused by liquid crystal disturbance around the main support columns, ensuring the normal display of the display panel, and reducing the blocking area of ​​the black matrix to ensure high-brightness display of the display panel; on the other hand, the main support columns are confined to the range blocked by the metal part, thereby avoiding the main support columns from sliding significantly when the display panel is squeezed by external force, resulting in uneven support in the box of the display panel, thereby affecting the support of the display panel, which is conducive to ensuring the display uniformity of the display panel.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] At present, the demand for thinner display panels is getting higher and higher, and the cost of display panels is constantly decreasing. These two factors have led to the continuous thinning and deletion of the film layer of the display panel. Driven by thinness and cost, it may be necessary to delete the planarization layer on the array substrate, which will cause the surface of the film layer to be uneven after the signal lines and driving elements in the display panel are patterned, that is, the area where the metal layer is set on the array substrate is thicker than the area where the metal layer is not set; when setting the display panel support column, in order to use the black matrix above the metal layer of the display panel to shield the support column at the same time, the support column will also be set in the area where the metal layer is located, so as to avoid the black matrix surface The area is large, which affects the transmittance of the display panel, but a problem arises at this time, because the metal layer in the display area is usually used as a signal routing, the purpose is to transmit signals to the pixel units in the display area, thereby driving the liquid crystal corresponding to the pixel units to rotate, so in order to give the display panel a larger light-transmitting area, the line width of the signal routing is getting narrower and narrower, so the protrusion formed by the signal routing is also narrower, and the support column stands above the signal routing with a narrow line width, which is equivalent to standing on an uneven surface. When external force is applied to the display panel, the support column is prone to tilt or slide, thereby affecting the supporting force of the display panel, resulting in light leakage, uneven display brightness and other problems.

[0031] Based on the above problems, an embodiment of the present invention provides a display panel, such as Figures 1 to 3 As shown, Figure 1 A schematic top view of a display panel provided by an embodiment of the present invention, Figure 2 for Figure 1 A schematic diagram of the display panel S area; Figure 3 for Figure 2 Schematic diagram of a cross section along section line A-A'; the display panel 1 includes an array substrate 10 and a color film substrate 20 that are relatively arranged, and a support column PS located between the array substrate 10 and the color film substrate 20, the support column PS includes a main support column MPS, the main support column MPS is arranged on one side of the color film substrate 20 and abuts against the array substrate 10, optionally, in other embodiments of the present invention, the main support column MPS may also be arranged on one side of the array substrate 10 and abut against the color film substrate 20.

[0032] The display panel 1 includes a plurality of sub-pixel units P1 arranged in an array, a scan line SL extending along a first direction X and a data line DL extending along a second direction Y, the first direction X and the second direction Y intersect, and the sub-pixel unit P1 is formed by the scan line SL and the data line DL intersecting, and optionally, Figure 2 As shown, the extension direction of the sub-pixel unit P1 includes Y1 and Y2, wherein the sub-pixel unit P1 includes a pixel electrode ( Figure 2 The extending direction of the pixel electrode also includes Y1 and Y2, and the extending direction of the data line DL also includes Y1 and Y2, wherein Y1, Y2 and the first direction X intersect with each other, that is, the sub-pixel unit P1 is a dual-domain sub-pixel unit; optionally, in other embodiments of the present invention, the sub-pixel unit P1 may also be a single-domain sub-pixel unit, or a multi-domain sub-pixel unit larger than the dual-domain, that is, the extending direction of the pixel electrode is single or not, which is included in the embodiments of the present invention.

[0033] The array substrate 10 includes a metal part M, and the main support pillars MPS in the display panel 1 include first support pillars PS1 , wherein the projection of the first support pillars PS1 is at least partially surrounded by the projection of the metal part M in a direction perpendicular to the plane where the display panel 1 is located.

[0034] The display panel 1 provided by the present invention, by at least partially surrounding the main support column MPS with the metal part M on the array substrate 10, does not need to significantly move the setting position of the main support column MPS, which is beneficial to reuse the black matrix above the metal part M to shield the metal part M and the main support column MPS at the same time, thereby avoiding light leakage caused by liquid crystal disturbance around the main support column MPS, ensuring the normal display of the display panel 1, and reducing the blocking area of ​​the black matrix to ensure high-brightness display of the display panel 1; on the other hand, the main support column MPS is confined to the range blocked by the metal part M, thereby avoiding the main support column MPS from sliding significantly when the display panel 1 is squeezed by external force, resulting in uneven support in the box of the display panel 1, thereby affecting the support of the display panel 1, which is beneficial to ensuring the display uniformity of the display panel 1.

[0035] Optional, please continue to refer to Figure 3 , exemplarily, the array substrate 10 has scan lines SL and data lines DL, wherein the scan lines SL are located in the first metal layer, and the data lines DL are located in the second metal layer, Figure 3The second metal layer is located between the support column PS and the first metal layer. Optionally, in other embodiments of the present invention, the first metal layer may be arranged between the support column PS and the second metal layer, wherein the metal portion M may be located on the same layer as the scan line SL, or on the same layer as the data line DL, or partially on the same layer as the scan line SL, and partially on the same layer as the data line DL. The metal portion M is integrated with the data line DL and / or the scan line SL on the same layer without adding an additional metal layer, which is beneficial to simplifying the process of the display panel 1 and saving production costs.

[0036] Optional, please refer to Figure 4 , Figure 4 for Figure 1 Another schematic diagram of the display panel S region; the display panel 1 includes a sub-pixel unit P1 including a thin film transistor T, and the thin film transistor T includes a gate, a source and a drain DE, wherein the scan line SL is electrically connected to the gate, the data line DL is electrically connected to the source, and the pixel electrode is electrically connected to the drain DE. The metal part M includes the data line DL and the first metal part M1, wherein the first metal part M1 and the data line DL and the drain DE are located in the same layer, and along the second direction Y, the orthographic projection of the first metal part M1 on the display panel 1 is at least located on both sides of the orthographic projection of the first support column PS1 on the display panel 1, and further, along the first direction X, the orthographic projection of the first support column PS1 on the display panel 1 can be set between the drain DE and the orthographic projection of the data line DL on the display panel 1, at this time, the first support column PS1 is partially surrounded by the data line DL, the first metal part M1 and the drain DE, that is, the first support column PS1 is limited to the three In the enclosed space, on the one hand, it is prevented that the main support column MPS slides significantly when the display panel 1 is squeezed by external force, resulting in uneven support of the display panel 1 in the box, thereby affecting the support of the display panel 1, which is conducive to ensuring the display uniformity of the display panel 1. On the other hand, the data line DL and the drain DE are reused as part of the metal part M, thereby avoiding the need to add additional metal parts in the first direction X, which is conducive to further simplifying the process, and also avoiding adding more metal parts, resulting in additional parasitic capacitance, and increasing the shielding area of ​​the black matrix, which is conducive to the high-brightness display of the display panel. It should be noted that Figure 4 Only one case is exemplarily shown, that is, the first support column PS1 is located between the drain electrode DE of the same sub-pixel unit P1 and the data line DL electrically connected thereto. Optionally, as Figure 5 , the first support column PS1 may also be located between the drain electrode DE of the sub-pixel unit P1 and the data line DL electrically connected to the adjacent sub-pixel unit P1, and at this time, the first support column PS1 is also surrounded by the data line DL, the first metal portion M1 and the drain electrode DE. Further, along the first direction X, the distance between the drain electrode DE and the data line DL can be adjusted according to the size of the first support column PS1, and the present invention does not limit this.

[0037] Optional, please refer to Figure 6 , Figure 6 for Figure 1 There is also a schematic diagram of the display panel S area; the metal part M includes a data line DL, and the projection of the first support column PS1 in a direction perpendicular to the plane where the display panel 1 is located is partially surrounded by the projection of the data line DL in a direction perpendicular to the plane where the display panel 1 is located, that is, the data line DL is wound in the area where the first support column PS1 is located, and there is a winding portion R; further, along the first direction X, the projection of the drain DE is located on the other side of the first support column PS1, that is, the first support column PS1 is partially surrounded by the data line DL and the drain DE. On the one hand, when the display panel 1 is squeezed by external force, the main support column MPS is prevented from sliding significantly, resulting in uneven support of the display panel 1 in the box, thereby affecting the support of the display panel 1, which is beneficial to ensuring the display uniformity of the display panel 1. On the other hand, the data line DL is reused as a part of the metal part M, so that there is no need to add an additional metal part, and only the extension direction of the data line DL in the area of ​​the first support column PS1 needs to be changed. The process is simple and easy to operate, saving production costs.

[0038] For further information, please refer to Figure 7 , Figure 7 for Figure 1 Another schematic diagram of the display panel S area; along the second direction Y, the projection of the first support column PS1 is located within the projection of the data line DL, that is, the data line DL is wound in the area where the first support column PS1 is located, and the winding portion R includes a first winding portion R1 and a third winding portion R3 that are relatively arranged along the second direction Y, and a second winding portion R2 that connects the first winding portion R1 and the third winding portion R3 and extends along the second direction Y, then the projections of the first winding portion R1 and the third winding portion R3 in the second direction Y completely cover the projection of the first support column PS1 in the second direction Y, that is, the dimensions of the first winding portion R1 and the third winding portion R3 along the first direction X are greater than or equal to the dimensions of the first support column PS1 along the first direction X, thereby further strengthening the restriction on the first support column PS1 in the second direction Y, preventing the first support column PS1 from sliding out from the gap between the data line DL and the drain electrode DE when the display panel 1 is squeezed by external force, resulting in uneven support in the box of the display panel 1, thereby affecting the support of the display panel 1, which is conducive to ensuring the display uniformity of the display panel 1.

[0039] It should be noted that, in the direction perpendicular to the display panel 1 , the distances between the drain DE of the thin film transistor T of any sub-pixel unit P1 and the projected edge of the data line DL along the first direction X can be set to be equal, which is beneficial to the uniform setting of the sub-pixel unit P1 and ensures the uniform display of the display panel 1 .

[0040] Optionally, the distance between the drain electrode DE of the adjacent sub-pixel unit P1 close to the winding portion R and the data line DL of the adjacent sub-pixel unit P1 along the first direction X may also be adjusted according to the size of the winding portion R of the data line DL along the first direction X. Please continue to refer to Figure 7 The sub-pixel unit includes a first sub-pixel unit P11 and a second sub-pixel unit P12, wherein the drain DE of the first sub-pixel unit P11 is adjacent to the winding portion R, and the drain DE of the second sub-pixel unit P12 is not adjacent to the winding portion R. Then, along the first direction X, the distance between the drain DE of the first sub-pixel unit P11 and the data line DL is a first distance L1, and the distance between the drain DE of the second sub-pixel unit P12 and the data line DL is a second distance L2, wherein L1<L2, that is, the drain DE of the first sub-pixel unit P11 provides some setting space for the winding portion R to avoid a short circuit between the drain DE and the data line DL, and also to avoid a large parasitic capacitance between the two, thereby affecting the display effect. The specific values ​​of L1 and L2 can be set according to the specific sizes of the sub-pixel unit P1 and the winding portion R, and the present invention is not limited to this.

[0041] Optional, please refer to Figure 8 , Figure 8 for Figure 1 Another schematic diagram of the display panel S area; the thin film transistor T includes an active layer K, the active layer K is a semiconductor material, the source and drain DE of the thin film transistor T are electrically connected to the active layer K respectively, wherein the winding portion R includes a first winding portion R1, a second winding portion R2 and a third winding portion R3, the first winding portion R1 and the third winding portion R3 include a portion extending along a first direction X, the second winding portion R2 includes a portion extending along a second direction Y, in a direction perpendicular to the plane where the display panel 1 is located, the projection of the active layer K overlaps with the projection of the second winding portion R2, that is, part of the active layer K overlaps with the second winding portion R2, when When the projection shape of the active layer K is U-shaped, the active layer K overlaps with the second winding portion R2, which is equivalent to shifting the active layer K toward the winding portion R, which is beneficial for setting the drain DE of the thin film transistor T at a position close to the first support column PS1, that is, the drain DE is closer to the first support column PS1 than when the active layer K is not shifted, and the distance between the drain DE and the data line DL along the first direction X is also maintained within an appropriate range, that is, in the first direction X, on the basis of further limiting the sliding of the first support column PS1, it also ensures the reasonable setting of the thin film transistor T, thereby ensuring the normal display of the display panel 1.

[0042] Optional, please refer to Fig. 9 and Fig.10 , Fig. 9 A schematic top view of another display panel provided by an embodiment of the present invention, Fig.10 for Fig. 9A schematic diagram of a display panel S' area; the display panel 2 also includes a touch electrode TE and a touch line TL, the touch line TL is electrically connected to the touch electrode TE, and the touch line TL and the data line DL can be located in the same metal layer; the metal part M includes the data line DL and the touch line TL, along the first direction X, the projection of the first support column PS1 in a direction perpendicular to the plane where the display panel 2 is located is located in a space enclosed by the projection of the data line DL and the touch line TL adjacent to the data line DL in a direction perpendicular to the plane where the display panel 2 is located, that is, the first support column PS1 is enclosed by the data line DL and the touch line TL, the touch line TL includes a touch line winding portion TR, and the data line DL includes a data line winding portion DR, wherein the touch line winding portion TR and the data winding portion DR are respectively wound in opposite directions in the area where the first support column PS1 is located, thereby limiting the first support column PS1 to the area formed by the two winding portions, thereby preventing the first support column PS1 from sliding, resulting in uneven support in the box of the display panel 2, thereby affecting the support of the display panel 2, which is conducive to ensuring the display uniformity of the display panel 2.

[0043] Optional, see Fig.11 and Fig.12 , Fig.11 for Fig. 9 Another schematic diagram showing the S' area of ​​the panel, Fig.12 for Figure 1 Another schematic diagram of the display panel S area; the metal part M also includes a scan line SL, and along the second direction Y, a projection of the first support column PS1 in a direction perpendicular to the plane where the display panel 2 is located is located on one side of the projection of the scan line SL in a direction perpendicular to the plane where the display panel 2 is located, that is, the first support column PS1 is surrounded by the data line DL, the scan line SL and the drain DE, or the first support column PS1 is surrounded by the data line DL, the scan line SL, the touch line TL and the drain DE, that is, in the second direction Y, the blocking effect on the first support column PS1 is increased, and at the same time, the first support column PS1 is also made to stand in a flatter area, that is, it is arranged away from the area where the data line DL, the touch line TL and the scan line SL are located, thereby ensuring that the first support column PS1 has good supporting force, thereby ensuring uniform box thickness of the display panel and ensuring display uniformity of the display panel.

[0044] Optional, such as Fig.13 , Fig.13 for Fig. 9Another schematic diagram of the display panel S' area; the metal part M also includes a metal line ML, wherein the metal line ML extends along a first direction X, the metal line ML and the scan line SL are located in the same metal layer, and along a second direction Y, the projections of the metal line ML and the scan line SL in a direction perpendicular to the plane where the display panel 2 is located are respectively located on both sides of the projection of the first support column PS1 in a direction perpendicular to the plane where the display panel 2 is located, that is, the first support column PS1 is partially surrounded by the metal line ML, the scan line SL, and the data line DL, or is completely surrounded by the metal line ML, the scan line SL, the data line DL and the touch line TL, so that the first support column PS1 basically does not slide significantly in any direction and angle, and the first support column PS1 stands on a flat surface, thereby ensuring that the display panel 2 has good support, ensuring that the box thickness of the display panel 2 is uniform, and ensuring the display uniformity of the display panel 2. It should be noted that the present invention does not limit the order in which the data lines DL and the touch lines TL are arranged along the first direction X, and also does not limit the order in which the scan lines SL and the metal lines ML are arranged along the second direction Y, that is, relative to the first support column PS1, the data lines DL can be arranged on the left side of the first support column PS1, or on the right side of the first support column PS1, and the touch lines TL are arranged on the other side opposite along the first direction X; similarly, the scan lines SL can be arranged on the lower side of the first support column PS1, or on the upper side of the first support column PS1, and the metal lines ML are arranged on the other side opposite along the second direction Y, thereby at least partially surrounding the first support column PS1.

[0045] Optionally, the metal line ML can be further set as a ground signal line. By setting the metal line ML as the ground signal line, on the one hand, the metal line ML can be prevented from being coupled by signals on surrounding signal lines, thereby causing display abnormalities in the display panel 2. On the other hand, it can be reused as an electrostatic conductor in the display panel 2, thereby quickly deriving residual static electricity in the sub-pixel unit P1 of the display panel 2, thereby ensuring normal display of the display panel 2.

[0046] Optional, see Figure 13 to Figure 15 , Fig.14 for Fig.13 Schematic diagram of the cross section along the section line B-B', Fig.15 for Fig.13Schematic diagram of a cross section along the section line CC'; along the first direction X, the projection width of the first support column PS1 in the direction perpendicular to the plane where the display panel 2 is located is h1, along the second direction Y, the projection width of the first support column PS1 in the direction perpendicular to the plane where the display panel 2 is located is h2, along the first direction X, the distance between the projections of the data line DL and the touch line TL in the direction perpendicular to the plane where the display panel 2 is located is d1, along the second direction Y, the distance between the projections of the scan line SL and the metal line ML in the direction perpendicular to the plane where the display panel 2 is located is d2; then d1-h1≤d2-h2. The width of the first support column PS1 in the first direction X and the second direction Y can be set to be consistent, that is, h1=h2, and the spacing d1 between the data line DL and the touch line TL in the first direction X is less than or equal to the spacing d2 between the scan line SL and the metal line ML in the second direction Y. Optionally, d1-h1≥1cm, d2-h2≥2cm. Firstly, due to the fluctuation of the alignment accuracy between the color film substrate 20 and the array substrate 10, the size of the first support column PS1 should be slightly smaller than the spacing between the metal parts M surrounding it, so as to avoid that the first support column PS1 cannot fall exactly within the encirclement of the metal part M under the fluctuation of the alignment accuracy, thereby affecting the support of the display panel 2; secondly, since the scan line SL and the metal line ML are located in the first metal layer, the data line DL and the touch line TL are located in the second metal layer, the first metal layer Compared with the second metal layer, the surface of the array substrate 10 which is farther away from the first support column PS1, that is, relatively more film layers need to be deposited on the first metal layer. The film layers have a certain thickness, and the spacing d2 between the scanning line SL and the metal line ML is set to be larger, so that after the subsequent film layers are stacked, the spacing between the protrusions formed in the areas where the scanning line SL and the metal line ML are located is within a reasonable range; thirdly, the spacing d2 between the scanning line SL and the metal line ML is set to be larger than the spacing d1 between the data line DL and the touch line TL, so that the scanning line SL and the metal line ML can avoid the winding part R of the data line DL and the touch line TL as much as possible, thereby minimizing the overlapping area of ​​the scanning line SL, the metal line ML and the data line DL, the touch line TL, thereby reducing the generated parasitic capacitance and ensuring the normal display of the display panel 2.

[0047] Optional, please refer to Fig.16 , Fig.16 for Fig. 9Another schematic diagram of the display panel S' region; the width h1 of the projection of the first support column PS1 in the direction perpendicular to the plane where the display panel 2 is located along the first direction X can be set to be smaller than the width h2 of the projection of the first support column PS1 in the direction perpendicular to the plane where the display panel 2 is located along the second direction Y, that is, the lateral width h1 of the first support column PS1 is set to be smaller than the longitudinal width h2 of the first support column PS1. Based on the fact that the first support column PS1 is enclosed by the data line DL and the touch line TL, that is, the data line DL and the touch line TL both have a winding portion R, if the lateral width of the first support column PS1 is equal to the longitudinal width, then the winding distance of the winding portion TR of the touch line TL and the winding portion DR of the data line DL in the first direction X is relatively large. At this time, reducing the size of the first support column PS1 in the first direction X and relatively increasing the size of the first support column PS1 in the second direction Y helps to ensure the transmittance of the sub-pixel unit P1 in the first direction X, while relatively reducing the transmittance of the sub-pixel unit P1 in the second direction Y. Because it is more important for the sub-pixel unit P1 to have a larger light-transmitting size in the first direction X, the pixel electrode ( Fig.16 The display panel 2 (not shown) includes a plurality of branches, and each branch extends approximately along the second direction Y to ensure that the display panel 2 has a larger electric field strength to obtain a higher transmittance, and the light-transmitting size in the first direction X affects the width of the pixel electrode and the number of pixel electrode branches, thereby greatly affecting the electric field strength and display brightness of the display panel 2. Therefore, the transverse width h1 of the first support column PS1 is set to be smaller than the longitudinal width h2 of the first support column PS1, the size of the first support column PS1 in the first direction X is reduced, and the size of the first support column PS1 in the second direction Y is relatively increased. At this time, the winding portion TR of the touch line TL includes a first touch winding portion TR1, a second touch winding portion TR2, and a third touch winding portion TR3 connected in sequence, wherein the second touch winding portion TR2 extends along the second direction Y, The extension directions of the first touch winding portion TR1 and the third touch winding portion TR3 intersect with the second direction Y and are not perpendicular, which is conducive to reducing the size of the winding portion TR of the touch line TL along the first direction X; similarly, at this time, the winding portion DR of the data line DL includes the first data winding portion DR1, the second data winding portion DR2, and the third data winding portion DR3 connected in sequence, wherein the second data winding portion DR2 extends along the second direction Y, and the extension directions of the first data winding portion DR1 and the third data winding portion DR3 intersect with the second direction Y and are not perpendicular, which is conducive to reducing the size of the winding portion DR of the data line DL along the first direction X; it helps to ensure the transmittance of the sub-pixel unit P1 in the first direction X, thereby ensuring the effective area of ​​the pixel electrode, which is conducive to the high-brightness display of the display panel 2.

[0048] Optional, see Figures 1 to 16The support column PS also includes an auxiliary support column SPS. In the direction perpendicular to the plane where the display panel 1 is located, the height of the main support column MPS is greater than the height of the auxiliary support column SPS, that is, the auxiliary support column SPS mainly plays an auxiliary supporting role. When the display panel 1 is not impacted by an external force, the auxiliary support column SPS does not contact the opposite substrate. Only when the display panel 1 is impacted by an external force, such as when an external force is pressed, it may abut against the opposite substrate. Optionally, by at least partially surrounding at least part of the auxiliary support columns SPS in some of the auxiliary support columns SPS with the metal portion M on the array substrate 10; on the one hand, the display panel 1 can be made When pressed by external force, the auxiliary support column SPS comes into contact with the opposite substrate, and the contact plane can also be relatively flat, thereby preventing the auxiliary support column SPS of the display panel 1 from sliding, thereby enhancing the supporting capacity of the display panel 1. On the other hand, the main support column MPS and the auxiliary support column SPS are set at the same position of the sub-pixel unit P1, so that the centers of the black matrix above the main support column MPS and the auxiliary support column SPS are approximately on the same horizontal line, which is also convenient for setting a narrower black matrix to block the support column PS, thereby maximizing the transmittance of the display panel 1 and further realizing high-brightness display of the display panel 1.
