[0006] Compared with the prior art, the technical solution provided by the present invention has the following advantages:

[0007] In the display panel provided by the present disclosure, the sub-pixels include blue sub-pixels, and the pixel opening area corresponding to the blue sub-pixels is the first pixel opening area. The vertical projection of the touch line or part of the data line on the plane where the first substrate is located partially overlaps with the vertical projection of the first pixel opening area on the plane where the first substrate is located, that is, along the direction perpendicular to the plane where the first substrate is located, the touch line or part of the data line partially overlaps with the first pixel opening area, that is, the touch line or part of the data line extends through the area corresponding to the first pixel opening area, thereby avoiding the touch line and the data line being simultaneously set between two adjacent pixel opening areas, which is beneficial to increasing the spacing between the touch line and the data line adjacent to it, thereby facilitating reducing the coupling interference of signals between the touch line and the data line adjacent to it, improving the signal accuracy of the display signal and the touch signal, ensuring a good display effect and touch accuracy, and avoiding short circuits between the touch line and the data line adjacent to it, which is beneficial to reducing the process difficulty and improving the preparation efficiency.

[0031] Specifically, the display panel provided in this embodiment may be a liquid crystal display panel, and the display panel includes a first substrate 10 and a second substrate 20 arranged opposite to each other.

A liquid crystal layer 50 is arranged between the first substrate 10 and the second substrate 20, and the liquid crystal layer 50 includes liquid crystal molecules. It can be understood that in this embodiment, the liquid crystal molecules of the liquid crystal layer 50 are positive liquid crystals for example. In some other optional embodiments, the liquid crystal molecules of the liquid crystal layer 50 may also be negative liquid crystals. In specific implementation, the setting may be selected according to actual needs.

[0032] The first substrate 10 of the present embodiment at least includes a substrate 11 and a first metal layer 12 and a first electrode layer 13 located on the side of the substrate 11 facing the second substrate 20. The first electrode layer 13 includes a first electrode 131. The first electrode 131 can be understood as a common electrode for accessing a common voltage signal. Optionally, the first substrate 10 of the present embodiment may also include a second electrode layer 14. The second electrode layer 14 can be understood as a pixel electrode layer for making a pixel electrode 40 corresponding to the sub-pixel P. The first electrode layer 13 of the present embodiment is located on the side of the first metal layer 12 facing the second substrate 20, and the second electrode layer 14 is located on the side of the first electrode layer 13 facing the second substrate 20 for example (such as Figure 3 In a specific implementation, the second electrode layer 14 may also be located on a side of the first electrode layer 13 away from the second substrate 20 (not shown in the figure), which is not limited in this embodiment.

[0033] Specifically, in the display panel provided in this embodiment, the first substrate 10 includes a plurality of scan lines G, a plurality of data lines D and a plurality of touch lines TP, the plurality of scan lines G extend along a first direction X and are arranged along a second direction Y, the plurality of data lines D extend along the second direction Y and are arranged along the first direction X, the plurality of touch lines TP extend along the second direction Y and are arranged along the first direction X, the scan lines G and at least part of the data lines D are insulated and cross-defined to form a plurality of pixel opening areas 30, wherein the first direction X intersects with the second direction Y. Optionally, the first direction X and the second direction Y are perpendicular to each other. Figure 1Taking the example that the scan line G extends in the first direction X, the data line D extends in the second direction Y, and the first direction X and the second direction Y are perpendicular to each other, the pixel opening area 30 defined by the mutually insulated intersection of the scan line G and part of the data line D can be understood as a block area. The display panel also includes a plurality of sub-pixels P, the sub-pixels P correspond to the pixel opening area 30, the vertical projection of the sub-pixel P on the plane where the first substrate 10 is located and the vertical projection of the corresponding pixel opening area 30 on the plane where the first substrate 10 is located at least partially overlap, and the sub-pixel P includes a pixel electrode 40, the vertical projection of the pixel electrode 40 on the plane where the first substrate 10 is located and the vertical projection of the corresponding pixel opening area 30 on the plane where the first substrate 10 is located at least partially overlap.

[0034] The first metal layer 12 of this embodiment can be understood as a conductive metal layer in the first substrate 10, which is used to make the metal conductive structure included in the display panel. For example, the touch line TP can be set in the first metal layer 12. Figure 2 and Figure 3 As shown, the substrate 11 side of the first substrate 10 may also include multiple metal film layers, such as multiple metal film layers used to make thin film transistors T, etc. The first metal layer 12 can be understood as one of the multiple metal film layers used to make thin film transistors T. Optionally, Figure 3 As shown, the side of the substrate 11 facing the second substrate 20 may also include at least a second metal layer 15 and an active layer 16. The second metal layer 15 is used to make the gate of the thin film transistor T, the scanning line G of the display panel, etc., and the active layer 16 is used to make the active part of the thin film transistor T. The first metal layer 12 is used to make the source and drain of the thin film transistor T, the data line D, etc., that is, the touch line TP and the data line D in this embodiment can be set in the same layer, and the touch line TP and the data line D in the same layer can be made by using a mask plate process, which is conducive to saving costs and simplifying the process. At the same time, it is conducive to reducing the thickness of the display panel. It can be understood that the first substrate 10 of this embodiment can also include other metal film layers, which will not be described in detail in this embodiment. For details, please refer to the structure of the liquid crystal display panel in the relevant technology for understanding. It can be understood that in other embodiments of the present disclosure, the touch line TP and the data line D can also be set in different metal film layers, which will not be described in detail in this disclosure.

[0035] The display panel provided in this embodiment can be a touch display panel, that is, the display panel integrates touch function and display function to realize the control and adjustment of the display panel according to the user's touch operation. When the display panel provided in this embodiment is displayed, the thin film transistor T is used as a switching device of the sub-pixel P in the display panel, and is used to transmit a pixel voltage signal to the pixel electrode in the on state. The gate of the thin film transistor T is connected to the scan line G of the display panel, and is connected to the scan drive circuit (not shown in the figure) via the scan line G. The source of the thin film transistor T is connected to the data line D, and is connected to the driving chip or flexible circuit board for providing a driving signal that is subsequently bound to the display panel via the data line D. The drain of the thin film transistor T is connected to the pixel electrode, and the data voltage signal is loaded to the pixel electrode through the data line D, so that an electric field that drives the deflection of the liquid crystal molecules of the liquid crystal layer 50 is formed between the pixel electrode 40 of the second electrode layer 14 and the first electrode 131 (common electrode) of the first electrode layer 13, thereby controlling whether the light is emitted or not by the deflection of the liquid crystal molecules, thereby realizing the display effect of the display panel. It is understandable that the display principle of the display panel is not elaborated in this embodiment, and during specific implementation, reference may be made to the display principle of the liquid crystal display panel in the related art for understanding.

[0036] In the display panel of the present embodiment, a first insulating layer 17 is included between the first metal layer 12 and the first electrode layer 13. The first insulating layer 17 can be understood as a flattening layer, which is used to insulate the structure of the first metal layer 12 from the structure of the first electrode layer 13, and can also flatten the structure of the first metal layer 12, which is conducive to the first electrode layer 13 made on the first insulating layer 17 to be as flat as possible, so as to ensure the display effect. In the present embodiment, when the touch line TP is made on the first metal layer 12 of the same layer as the data line D, a plurality of first via holes are opened in the first insulating layer 17, so that the first electrode 131 of the first electrode layer 13 is electrically connected to the touch line TP of the first metal layer 12 by passing through the first via hole, and the first electrode 131 is reused as a touch electrode in the touch stage of the display panel, and the touch signal is transmitted through the touch line TP to realize the touch detection function. The first electrode layer 13 and the second electrode layer 14 can be formed of a transparent conductive material, such as ITO (Indium Tin Oxides, indium tin oxide semiconductor transparent conductive film), etc., which is not limited in the present embodiment. The first electrode 131 of the first electrode layer 13 can be a block structure. It can be understood that the area of ​​the first electrode 131 of the block structure can be larger than the area of ​​a single sub-pixel P, that is, one first electrode 131 can correspond to multiple sub-pixels P. When the display panel performs touch detection, a detection capacitor is formed between the block-shaped first electrode 131 and the common ground. When a touch subject such as a finger touches the display panel for detection, the capacitance formed between the finger and the capacitor is superimposed on the first electrode 131 as a touch electrode, thereby forming the coordinates of the touch point and completing the detection of the touch position. It can be understood that the touch detection principle of the display panel is not elaborated in this embodiment. When it is implemented specifically, it can be understood by referring to the touch principle of the embedded touch display panel in the related art.

[0037] It should be noted that the shape of the pixel electrode 40 is only exemplarily drawn in the figure of this embodiment. In specific implementation, the shape of the pixel electrode 40 includes but is not limited to this, and can also be other shapes, which is not limited in this embodiment.

[0038] In the display panel of the present embodiment, the sub-pixel P includes a blue sub-pixel P1, and the pixel opening area 30 corresponding to the blue sub-pixel P1 is a first pixel opening area 31. The vertical projection of the touch line TP on the plane where the first substrate 10 is located partially overlaps with the vertical projection of the first pixel opening area 31 on the plane where the first substrate 10 is located, that is, along the direction perpendicular to the plane where the first substrate 10 is located, the touch line TP partially overlaps with the first pixel opening area 31, that is, the touch line TP extends through the area corresponding to the first pixel opening area 31, so that the touch line TP and the data line D are avoided from being simultaneously arranged between two adjacent pixel opening areas 30, which is beneficial to increase the spacing between the touch line TP and the data line D adjacent to it, thereby facilitating the reduction of the coupling interference of the signal between the touch line TP and the data line D adjacent to it, improving the signal accuracy of the display signal and the touch signal, ensuring a good display effect and touch accuracy, and avoiding the short circuit between the touch line TP and the data line D adjacent to it, which is beneficial to reduce the process difficulty and improve the preparation efficiency. At the same time, the touch line TP extends through the area corresponding to the first pixel opening area 31, so as to avoid the touch line TP and the data line D being set between two adjacent pixel opening areas 30 at the same time, which can effectively reduce the area of ​​the non-opening area, thereby facilitating the increase of the effective light transmission area of ​​the sub-pixel P and improving the display effect. Further, the sub-pixels P of each color in the display panel have a low proportion of blue light components when cooperating to display white, that is, in the display panel, relative to the sub-pixels P of other colors, exemplarily, relative to the red sub-pixel and the green sub-pixel, the display brightness of the blue sub-pixel P1 is smaller, and the setting of the touch line TP has less effect on the display effect of the blue sub-pixel P1, so that the touch line TP extends through the area corresponding to the first pixel opening area 31, and the first pixel opening area 31 corresponds to the blue sub-pixel P1, that is, the touch line TP extends through the area corresponding to the blue sub-pixel P1, which is conducive to reducing the effect of the touch line TP being set in the pixel opening area 30 on the display effect.

[0039] Figure 4 is a plan view of another display panel provided by the present disclosure, Figure 5 yes Figure 4 An enlarged schematic diagram of the C portion of the display panel, see Figure 4 and Figure 5 , a vertical projection of a portion of the data line D on the plane where the first substrate 10 is located overlaps with a vertical projection of the first pixel opening area 31 on the plane where the first substrate 10 is located.

[0040] Specifically, in the display panel of the present embodiment, the sub-pixel P includes a blue sub-pixel P1, and the pixel opening area 30 corresponding to the blue sub-pixel P1 is a first pixel opening area 31. A vertical projection of a portion of the data line D on the plane where the first substrate 10 is located partially overlaps with a vertical projection of the first pixel opening area 31 on the plane where the first substrate 10 is located, that is, along a direction perpendicular to the plane where the first substrate 10 is located, a portion of the data line D partially overlaps with the first pixel opening area 31, that is, a portion of the data line D extends through an area corresponding to the first pixel opening area 31, thereby avoiding the data line D and the touch line TP from being simultaneously arranged between two adjacent pixel opening areas 30, which is beneficial to increasing the spacing between the touch line TP and the data line D adjacent thereto, thereby facilitating reducing the coupling interference of signals between the touch line TP and the data line D adjacent thereto, improving the signal accuracy of the display signal and the touch signal, ensuring a good display effect and touch accuracy, and avoiding a short circuit between the touch line TP and the data line D adjacent thereto, which is beneficial to reducing the process difficulty and improving the preparation efficiency. At the same time, part of the data line D extends through the area corresponding to the first pixel opening area 31, so as to avoid the touch line TP and the data line D being set between two adjacent pixel opening areas 30 at the same time, which can effectively reduce the area of ​​the non-opening area, thereby facilitating the increase of the effective light transmission area of ​​the sub-pixel P and the display effect. Further, relative to sub-pixels P of other colors, exemplarily, relative to red sub-pixels and green sub-pixels, the display brightness of the blue sub-pixel P1 is smaller, and the setting of the data line D has less effect on the display effect of the blue sub-pixel P1, so that part of the data line D extends through the area corresponding to the first pixel opening area 31, and the first pixel opening area 31 corresponds to the blue sub-pixel P1, that is, part of the data line D extends through the area corresponding to the blue sub-pixel P1, which is conducive to reducing the effect of the display effect when the part of the data line D is set in the pixel opening area 30.

[0041] It should be noted that when a portion of the data line D extends through the area corresponding to the blue sub-pixel P1 , the first pixel opening area 31 corresponding to the blue sub-pixel P1 is defined by the insulated intersection of the scan line G and the touch line TP.

[0042] It can be understood that the figure of this embodiment only illustrates the structure of the display panel by way of example. In a specific implementation, the structure of the display panel includes but is not limited to this, and may also include other structures capable of realizing display and touch functions. For details, reference may be made to the structure of the liquid crystal display panel in the related art for understanding, and this embodiment will not be elaborated here.

[0043] Figure 6 yes Figure 2 A cross-sectional view of the display panel along the DD' line, referring to Figure 1-Figure 3 and Figure 6In some optional embodiments, the vertical projection of the touch line TP on the plane where the first substrate 10 is located partially overlaps with the vertical projection of the pixel electrode 40 in the blue sub-pixel P1 on the plane where the first substrate 10 is located.

[0044] Specifically, the vertical projection of the touch line TP on the plane where the first substrate 10 is located partially overlaps with the vertical projection of the first pixel opening area 31 on the plane where the first substrate 10 is located, that is, along the direction perpendicular to the plane where the first substrate 10 is located, the touch line TP partially overlaps with the first pixel opening area 31, that is, the touch line TP extends through the area corresponding to the first pixel opening area 31. Further, the vertical projection of the touch line TP on the plane where the first substrate 10 is located partially overlaps with the vertical projection of the pixel electrode 40 in the blue sub-pixel P1 on the plane where the first substrate 10 is located, that is, the touch line TP extends through the area corresponding to the pixel electrode 40 in the blue sub-pixel P1. Since the transmittance of the area corresponding to the pixel electrode 40 in the blue sub-pixel P1 is lower than the transmittance of the area corresponding to the blue sub-pixel P1 where the pixel electrode 40 is not set, the touch line TP extends through the area corresponding to the pixel electrode 40 in the blue sub-pixel P1, which is conducive to reducing the influence of the touch line TP on the display effect when it is set in the pixel opening area 30.

[0045] Figure 7 yes Figure 5 A cross-sectional view of the display panel along the line EE', referring to Figure 4 , Figure 5 and Figure 6 , a vertical projection of a portion of the data line D on the plane where the first substrate 10 is located overlaps with a vertical projection of the pixel electrode 40 in the blue sub-pixel P1 on the plane where the first substrate 10 is located.

[0046] Specifically, the vertical projection of a portion of the data line D on the plane where the first substrate 10 is located overlaps with the vertical projection of the first pixel opening area 31 on the plane where the first substrate 10 is located, that is, along the direction perpendicular to the plane where the first substrate 10 is located, the portion of the data line D overlaps with the first pixel opening area 31, that is, the portion of the data line D extends through the area corresponding to the first pixel opening area 31. Further, the vertical projection of the portion of the data line D on the plane where the first substrate 10 is located overlaps with the vertical projection of the pixel electrode 40 in the blue sub-pixel P1 on the plane where the first substrate 10 is located, that is, the portion of the data line D extends through the area corresponding to the pixel electrode 40 in the blue sub-pixel P1. Since the transmittance of the area corresponding to the pixel electrode 40 in the blue sub-pixel P1 is lower than the transmittance of the area corresponding to the blue sub-pixel P1 where the pixel electrode 40 is not set, the portion of the data line D extends through the area corresponding to the pixel electrode 40 in the blue sub-pixel P1, which is conducive to reducing the influence of the portion of the data line D on the display effect when it is set in the pixel opening area 30.

[0047] Continue to refer Figure 1 and Figure 2 In some optional embodiments, the sub-pixel P further includes a first color sub-pixel P2, the pixel opening area 30 corresponding to the first color sub-pixel P2 is a second pixel opening area 32, a vertical projection of the touch line TP on the plane where the first substrate 10 is located does not overlap with a vertical projection of the second pixel opening area 32 on the plane where the first substrate 10 is located, and a vertical projection of the data line D on the plane where the first substrate 10 is located does not overlap with a vertical projection of the second pixel opening area 32 on the plane where the first substrate 10 is located;

[0048] The width of the first pixel opening region 31 along the first direction X is greater than the width of the second pixel opening region 32 along the first direction X.

[0049] Specifically, the sub-pixel P further includes a first color sub-pixel P2, and the display color of the first color sub-pixel P2 is different from the display color of the blue sub-pixel P1. Exemplarily, the first color sub-pixel P2 may be a red sub-pixel, or a green sub-pixel. Of course, in other embodiments of the present disclosure, the first color sub-pixel P2 may also be a sub-pixel P of other colors, which will not be described in detail in the present disclosure.

[0050] The pixel opening area 30 corresponding to the first color sub-pixel P2 is the second pixel opening area 32, the vertical projection of the touch line TP on the plane where the first substrate 10 is located does not overlap with the vertical projection of the second pixel opening area 32 on the plane where the first substrate 10 is located, and the vertical projection of the data line D on the plane where the first substrate 10 is located does not overlap with the vertical projection of the second pixel opening area 32 on the plane where the first substrate 10 is located, that is, the touch line TP and the data line D do not extend through the second pixel opening area 32 corresponding to the first color sub-pixel P2, and the setting of the touch line TP and the data line D will not affect the transmittance of the area corresponding to the first color sub-pixel P2. The touch line TP or part of the data line D extends through the area corresponding to the pixel electrode 40 in the blue sub-pixel P1, so that the touch line TP or part of the data line D affects the transmittance of the area corresponding to the pixel electrode 40 in the blue sub-pixel P1. The width of the first pixel opening area 31 along the first direction X is greater than the width of the second pixel opening area 32 along the first direction X, that is, the width of the first pixel opening area 31 along the first direction X is larger, which is beneficial to alleviate the influence of the touch line TP or part of the data line D extending through the area corresponding to the pixel electrode 40 in the blue sub-pixel P1 on the transmittance of the area corresponding to the pixel electrode 40 in the blue sub-pixel P1.

[0051] Continue to refer Figure 1 and Figure 2 In some optional embodiments, the pixel electrode 40 includes a plurality of first branches 41 electrically connected to each other, and in the same pixel electrode 40, the first branches 41 are arranged along the first direction X;

[0052] The width of the first branch 41 in the blue sub-pixel P1 along the first direction X is greater than the width of the first branch 41 in the first color sub-pixel P2 along the first direction X.

[0053] Specifically, the pixel electrode 40 includes a plurality of first branches 41 arranged along the first direction X, and in the same pixel electrode 40, the first branches 41 are electrically connected to each other. The width of the first branch 41 in the blue sub-pixel P1 along the first direction X is greater than the width of the first branch 41 in the first color sub-pixel P2 along the first direction X, so that the width of the pixel electrode 40 in the blue sub-pixel P1 along the first direction X is greater than the width of the pixel electrode 40 in the first color sub-pixel P2 along the first direction X, thereby achieving that the width of the first pixel opening area 31 along the first direction X is greater than the width of the second pixel opening area 32 along the first direction X, thereby facilitating the influence of the touch line TP or part of the data line D extending through the area corresponding to the pixel electrode 40 in the blue sub-pixel P1 on the transmittance of the area corresponding to the pixel electrode 40 in the blue sub-pixel P1.

[0055] The number of the first branches 41 in the blue sub-pixel P1 is greater than the number of the first branches 41 in the first color sub-pixel P2 .

[0056] Specifically, the pixel electrode 40 includes a plurality of first branches 41 arranged along the first direction X, and in the same pixel electrode 40, the first branches 41 are electrically connected to each other. The number of first branches 41 in the blue sub-pixel P1 is greater than the number of first branches 41 in the first color sub-pixel P2, so that the width of the pixel electrode 40 in the blue sub-pixel P1 along the first direction X is greater than the width of the pixel electrode 40 in the first color sub-pixel P2 along the first direction X, thereby achieving that the width of the first pixel opening area 31 along the first direction X is greater than the width of the second pixel opening area 32 along the first direction X, thereby facilitating the influence of the touch line TP or part of the data line D extending through the area corresponding to the pixel electrode 40 in the blue sub-pixel P1 on the transmittance of the area corresponding to the pixel electrode 40 in the blue sub-pixel P1.

[0057] Continue to refer Figure 1 and Figure 2In some optional embodiments, along the first direction X, the distances between two adjacent pixel opening areas 30 are the same.

[0058] Specifically, the vertical projection of the touch line TP or part of the data line D on the plane where the first substrate 10 is located partially overlaps with the vertical projection of the first pixel opening area 31 on the plane where the first substrate 10 is located, that is, along the direction perpendicular to the plane where the first substrate 10 is located, the touch line TP or part of the data line D partially overlaps with the first pixel opening area 31, that is, the touch line TP or part of the data line D extends through the area corresponding to the first pixel opening area 31, thereby avoiding the touch line TP and the data line D being simultaneously set between two adjacent pixel opening areas 30, so that along the first direction X, the distance between each adjacent two pixel opening areas 30 can be set to be the same, that is, the setting of the touch line TP will not cause an increase in the distance between two adjacent pixel opening areas 30, which is beneficial to increasing the effective light transmission area of ​​the sub-pixel P and improving the display effect.

[0060] Specifically, when the display panel is in the display stage, the first electrode 131 is a common electrode, and an electric field that drives the deflection of the liquid crystal molecules of the liquid crystal layer 50 is formed between the pixel electrode 40 and the first electrode 131, so as to control whether the light is emitted or not through the deflection of the liquid crystal molecules, thereby achieving the display effect of the display panel. The first electrode 131 includes a first slit 1311, and the vertical projection of the first slit 1311 on the plane where the first substrate 10 is located does not overlap with the vertical projection of the pixel opening area 30 on the plane where the first substrate 10 is located, that is, the first slit 1311 is not set in the area corresponding to the pixel opening area 30, so that the setting of the first slit 1311 does not affect the formation of the electric field between the pixel electrode 40 and the first electrode 131 when the display panel is in the display stage, that is, it is effectively avoided that the setting of the first slit 1311 affects the display effect of the display panel.

[0061] Continue to refer Figure 4 , Figure 5 and Figure 7 In some optional embodiments, a vertical projection of the first slit 1311 on the plane where the first substrate 10 is located partially overlaps with a vertical projection of the touch line TP on the plane where the first substrate 10 is located.

[0062] Specifically, when the vertical projection of part of the data line D on the plane where the first substrate 10 is located overlaps with the vertical projection of the first pixel opening area 31 on the plane where the first substrate 10 is located, the touch line TP extends through between the first pixel opening area 31 and the pixel opening area 30 adjacent thereto, and the vertical projection of the first slit 1311 on the plane where the first substrate 10 is located can be set to overlap with the vertical projection of the touch line TP on the plane where the first substrate 10 is located, effectively reducing the overlapping area of ​​the vertical projection of the first electrode 131 on the plane where the first substrate 10 is located and the vertical projection of the touch line TP on the plane where the first substrate 10 is located, thereby effectively reducing the parasitic capacitance between the first electrode 131 and the touch line TP, which is beneficial to improving the display effect of the display panel.

[0063] Continued reference Figure 1 , Figure 2 and Figure 6 , the vertical projection of the first slit 1311 on the plane where the first substrate 10 is located overlaps with the vertical projection of part of the data line D on the plane where the first substrate 10 is located.

[0067] Specifically, the display panel further includes a plurality of spacers PS disposed between the first substrate 10 and the second substrate 20. The spacers PS can ensure a uniform thickness of the liquid crystal layer 50. This can ensure the consistency and stability of the display effect. At the same time, the spacers PS can also support the first substrate 10 and the second substrate 20. The spacers PS can well support the thickness of the liquid crystal cell of the display panel. The thickness of the liquid crystal cell of the display panel can be kept uniform, so that the transmittance, contrast, response speed and other performances of each position of the display panel are not affected by external pressure, thereby ensuring the display effect.

The second spacer column PS2 is an auxiliary spacer column, and the second spacer column PS2 is mainly used to buffer when receiving external force.

[0072] The vertical projection of the first spacer PS1 on the plane where the first substrate 10 is located overlaps with the vertical projection of a group of adjacent touch lines TP and data lines D on the plane where the first substrate 10 is located, that is, the first spacer PS1 is arranged in the area corresponding to the adjacent touch lines TP and data lines D, which is conducive to improving the support effect of the first spacer PS1. The vertical projection of the second spacer PS2 on the plane where the first substrate 10 is located does not overlap with the vertical projection of the touch line TP on the plane where the first substrate 10 is located, that is, the second spacer PS2 is arranged in other areas, which is conducive to increasing the number of spacers PS, so that the thickness of the liquid crystal cell of the display panel can be more stable.

[0073] Optionally, the vertical projection of the second spacer column PS2 on the plane where the first substrate 10 is located may not overlap with the vertical projection of the data line D on the plane where the first substrate 10 is located, that is, the second spacer column PS2 may be arranged in the area corresponding to the data line D, which is beneficial to improve the supporting effect of the second spacer column PS2.

The structure of the light shielding portion 22 can be referred to Figure 3 and Figure 6 sectional diagram for understanding).

[0076] Optionally, a light shielding portion 22 may be provided between the color resists 21 of different colors to shield light, so as to avoid color mixing between sub-pixels P of different colors.
