Description

Technical Field

[0001] The present invention relates to the field of display technologies, and particularly to a display substrate, a display panel, and a display device. Background Art

[0002] With the development of display technologies, the resolution of TV products is getting higher and higher, and the corresponding aperture ratio is gradually decreasing. However, the demand for power consumption is becoming stronger and stronger. This requires significantly improving the light extraction efficiency without increasing power consumption.

[0003] In the design of existing products, spacers are used to maintain the stability and uniformity of the liquid crystal cell thickness, and they are generally cylindrical. Under the action of external forces, the cylindrical spacers are prone to sliding, and thus slide from the light-blocking area of the array substrate to the light-transmitting area. During this process, the alignment film will be scratched, resulting in abnormal alignment of the liquid crystal. After the spacers return, this will lead to abnormal display.

[0004] The main current solution is to design a larger black matrix (BM) on the color filter substrate for shielding, which causes a decrease in the aperture ratio of the product, and further leads to a reduction in light efficiency. Summary of the Invention

[0050] As Figures 1 to 4 shown, this application provides a display substrate, which includes:

[0051] an array substrate 100 and a color filter substrate 200;

[0052] On one side of the array substrate 100 close to the color filter substrate 200, a plurality of data lines 130 extending along a first direction F1 and a plurality of signal line groups 120 extending along a second direction F2 are provided, and the plurality of data lines 130 and the plurality of signal line groups 120 form a grid structure;

[0053] On one side of the color filter substrate 200 close to the array substrate 100, a plurality of strip-shaped spacers 320 are provided, the spacers 320 extend along the second direction F2, and the orthographic projection of the spacers 320 on the array substrate 100 partially overlaps with the signal line groups 120 and the data lines 130.

[0054] This application utilizes the thickness of the signal line group and the data line itself in cooperation with the long strip spacers to form a structure for supporting the thickness of the liquid crystal cell. When the spacers are displaced, the support of the data line and the signal line group can prevent the spacers from scratching the alignment film.

[0055] The following will detail each embodiment of this application that conforms to the above creative concept.

[0056] As Figures 1 to 5 shown, this application provides a display substrate, which includes an array substrate 100 and a color filter substrate 200.

[0057] The array substrate 100 includes a first substrate 110 and a driving circuit structure. The first substrate 110 can be a rigid substrate. Such a rigid substrate can be, for example, a glass substrate or a PMMA (Polymethyl methacrylate) substrate, etc. The first substrate 110 can also be a flexible substrate. For example, such a flexible substrate can be a PET (Polyethyleneterephthalate) substrate, a PI (Polyimide) substrate, or a PEN (Polyethylene naphthalate two formic acid glycol ester) substrate, etc. It can be understood that the type of the first substrate 110 includes various types and can be selected and set according to actual needs. The embodiments of the present disclosure do not limit this.

[0058] On one side of the base 110 close to the color filter substrate 200, a driving circuit structure is provided. The driving circuit structure includes a plurality of data lines 130 extending along a first direction F1 and a plurality of signal line groups 120 extending along a second direction F2. The first direction F1 intersects with the second direction F2, the data lines 130 intersect with the signal line groups 120, and the plurality of data lines 130 and the plurality of signal line groups 120 form a plurality of grid structures. The plurality of grid structures define a plurality of pixel regions 400. Each grid structure corresponds to a pixel region 400, and the pixel region 400 can be a red pixel region, a green pixel region or a blue pixel region. Each pixel region 400 is jointly controlled by the data lines 130 and the signal line groups 120 located at its edge. The data lines 130 charge the liquid crystal capacitor Clc and the storage capacitor Cstg of the pixel region under the control of the signal line groups 120, thereby controlling the light emission of the pixel region 400. Optionally, the first direction F1 can be perpendicular to the second direction F2, that is, the data lines 130 can be perpendicular to the signal line groups 120, and the plurality of data lines 130 and the plurality of signal line groups 120 form a square grid-like structure. Optionally, the data lines 130 can be arranged on the side of the signal line groups 120 close to the color filter substrate 200, or the data lines 130 can also be arranged on the side of the signal line groups 120 far from the color filter substrate 200. An interlayer insulating layer 150 and a gate insulating layer 160 are provided between the data lines 130 and the signal line groups 120. The gate insulating layer 160 is located on the side close to the signal line groups 120, and the interlayer insulating layer 150 is located on the side close to the data lines 130. A alignment film is provided on the side of the driving circuit structure close to the color filter substrate 200.

[0059] The color filter substrate 200 includes a second base 210 and a color filter layer 220. The second base 210 can be a rigid base. Such a rigid base can be, for example, a glass base or a PMMA (Polymethyl methacrylate) base, etc. The second base 210 can also be a flexible base. For example, such a flexible base can be a PET (Polyethyleneterephthalate) base, a PI (Polyimide) base or a PEN (Polyethylene naphthalate two formic acid glycol ester) base, etc. It can be understood that the types of the second base 210 include many kinds and can be selected and set according to actual needs, and the embodiments of the present disclosure do not limit this.

[0060] A filter layer 220 is disposed on a side of the second substrate 210 close to the array substrate 100. The filter layer 220 includes a black matrix 221 and a color film layer 222. The color film layer 222 is disposed corresponding to the pixel region 400. The orthographic projection of the color film layer 222 on the array substrate 100 covers the pixel region 400. The color film layer 222 includes a red color film layer, a green color film layer, and a blue color film layer. Different pixel regions 400 respectively correspond to different color film layers 222. The orthographic projection of the black matrix 221 on the array substrate 100 covers the region of the non-pixel region 400. For example, the black matrix 221 covers structures such as the data lines 130, the signal line groups 120, the transistors 170, and the spacers 320. Specifically, the orthographic projection of the black matrix 221 on the array substrate 100 covers structures such as the data lines 130, the signal line groups 120, the transistors 170, and the spacers 320, and the distance between the covered structures and the edge of the orthographic projection of the black matrix 221 on the array substrate 100 is greater than or equal to 50 μm. The black matrix 221 also separates different pixel regions 400 to prevent accidents such as color bleeding, which may affect the final display effect. The black matrix 221 can also prevent the spacers 320 from slipping, resulting in abnormal panel display, and shield the scratching distance. A alignment film is disposed on a side of the filter layer 220 close to the array substrate 100.

[0061] A liquid crystal layer 300 is disposed between the array substrate 100 and the color film substrate 200. The liquid crystal layer 300 is filled with liquid crystal. Under the control of the signal line groups 120, the data lines 130 charge the liquid crystal capacitor Clc and the storage capacitor Cstg in the pixel region. Under the electric field of the liquid crystal capacitor Clc, the liquid crystal molecules maintain a certain orientation and deflection, thereby realizing the control of the light intensity of the light passing through the liquid crystal layer 300.

[0062] The liquid crystal layer 300 between the array substrate 100 and the color film substrate 200 is supported by the spacers 320. One end of the spacer 320 is supported on the array substrate 100, and the other end is supported on the color film substrate 200, so as to maintain the liquid crystal layer 300 to have a certain thickness. Optionally, a plurality of strip-shaped spacers 320 are disposed on a side of the color film substrate 200 close to the array substrate 100. The strip-shaped spacers 320 extend along the second direction F2, and the orthographic projection of the spacers 320 on the array substrate 100 partially overlaps with the signal line groups 120.

[0063] As Figures 1 to 5As shown, in an alternative embodiment, the signal line group 120 includes a first signal line 121 and a second signal line 122. The first signal line 121 controls the connection between the data line 130, the liquid crystal capacitor Clc, and the storage capacitor Cstg through the transistor 170, that is, the first signal line 121 controls whether the data line 130 charges the liquid crystal capacitor Clc and the storage capacitor Cstg. The second signal line 122 is connected to the common electrode, and the second signal line 122 provides a stable voltage for one end of the liquid crystal capacitor Clc and the storage capacitor Cstg, so as to keep a stable pressure difference between the liquid crystal capacitor Clc and the storage capacitor Cstg, and further keep the liquid crystal molecules at a directional deflection angle. Optionally, a signal line group 120 includes one first signal line 121 and one second signal line 122. Among them, the first signal line 121 controls the on / off of the data line 130 of a row of pixel regions 400 through a plurality of transistors 170, and the second signal line 122 provides a stable voltage for one end of the liquid crystal capacitor Clc and the storage capacitor Cstg of an adjacent row of pixel regions 400.

[0064] The orthographic projection of the spacer 320 onto the array substrate 100 covers the area between the first signal line 121 and the second signal line 122 in the signal line group 120. The orthographic projection of the spacer 320 onto the array substrate 100 partially overlaps with the first signal line 121. The orthographic projection of the spacer 320 onto the array substrate 100 partially overlaps with the second signal line 122. That is, within the length range of the spacer 320, the orthographic projection onto the array substrate 100 covers part of the first signal line 121, part of the second signal line 122, and the area between the first signal line 121 and the second signal line 122. For example, the width of the spacer 320 can be a. The width of the area between the first signal line 121 and the second signal line 122 is d, that is, the distance between the first signal line 121 and the second signal line 122 in the same signal line group 120 is d. The alignment deviation between the array substrate 100 and the color filter substrate 200 is c, that is, during the alignment process of the array substrate 100 and the color filter substrate 200, the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c. Then a = d + 2c. That is, in the case where there is no deviation during the alignment of the array substrate 100 and the color filter substrate 200, the width of the orthographic projection of the spacer 320 onto the array substrate 100 covering the first signal line 121 is c, and the width of the orthographic projection of the spacer 320 onto the array substrate 100 covering the second signal line 122 is c. Optionally, the average width of the first signal line 121 is b, and the average width of the second signal line 122 is e. Wherein, b is greater than or equal to 2c, and e is greater than or equal to 2c. Thus, when a slight deviation occurs during the alignment process of the array substrate 100 and the color filter substrate 200, the width of the overlapping part of the orthographic projection of the spacer 320 onto the array substrate 100 with the first signal line 121 and the second signal line 122 is always 2c. Thus, it can be ensured that the spacer 320 can provide stable support for the liquid crystal layer 300, and further ensure that the liquid crystal layer 300 can maintain a stable thickness, and further ensure the display effect of the display panel. Optionally, e can be greater than b, so as to ensure the uniformity of the voltage provided by the second signal line 122, thereby ensuring the stability of the deflection of liquid crystal molecules.

[0065] The distances from the side of the spacer 320 away from the color filter substrate 200 to the color filter substrate 200 are equal. The length of the spacer 320 is greater than the pitch between two adjacent data lines 130. The overlapping regions of the data lines 130 and the signal line group 120 form a plurality of columnar structures 140 protruding towards the color filter substrate 200, and the side of the spacer 320 away from the color filter substrate 200 abuts against some of the columnar structures 140. In this way, the spacer 320 cooperates with the data lines 130 and the signal line group 120 to form different spacer regions on itself. The part where the side of the spacer 320 away from the color filter substrate 200 abuts against some of the columnar structures 140 forms the main spacer region 321. The orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the data lines 130 or the signal line group 120, and the part that does not overlap with the columnar structures 140 forms the first sub-spacer region 322. The part where the orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the region between the first signal line 121 and the second signal line 122 in the signal line group 120 forms the second sub-spacer region 323. The side of the columnar structure 140 close to the color filter substrate 200 abuts against the spacer 320. The distance between the side of the region on the data line 130 or the signal line group 120 that is not the columnar structure 140 and close to the color filter substrate 200 and the spacer 320 is f. The distance between the region between the first signal line 121 and the second signal line 122 in the signal line group 120 and the spacer 320 is g. g > f > 0. In this way, the spacer 320 cooperates with the data lines 130 and the signal line group 120 to form the main spacer region 321, the first sub-spacer region 322, and the second sub-spacer region 323 with a step difference. In the normal state, the main spacer region 321 of the spacer 320 provides support for the liquid crystal cell thickness. When the display substrate is pressed, the color filter substrate 200 sinks towards the array substrate 100, and the first sub-spacer region 322 participates in the support of the liquid crystal cell thickness. When the display substrate is pressed strongly, the degree of sinking of the color filter substrate 200 towards the array substrate 100 increases, and at this time, the second sub-spacer region 323 also starts to participate in the support of the liquid crystal cell thickness.

[0066] The signal line group 120 is provided with a plurality of winding areas 123 along its length direction. The winding areas 123 are provided at the positions where at least one signal line group 120 intersects with the data line 130. Specifically, the winding areas 123 are provided at the positions where at least one first signal line 121 and / or at least one second signal line 122 intersect with the data line 130. The orthographic projection of the spacer 320 in the winding area 123 on the array substrate 100 has no overlapping area with the columnar structure 140. For example, the signal line group 120 includes a first signal line 121 and a second signal line 122. The first signal line 121 and the second signal line 122 extend along the length direction of the signal line group 120, i.e., the second direction F2, in the non-winding area 123. In the winding area 123, the first signal line 121 bends away from the second signal line 122 by a certain distance, then extends along the length direction of the signal line group 120, bypasses the columnar structure 140, and then bends towards the second signal line 122 and extends to a position collinear with the first signal line 121 in the non-winding area 123, and then continues to extend along the length direction of the signal line group 120. That is, in the winding area 123, the first signal line 121 bulges along the first direction F1 to avoid the spacer 320. In the winding area 123, the second signal line 122 bends away from the first signal line 121 by a certain distance, then extends along the length direction of the signal line group 120, bypasses the columnar structure 140, and then bends towards the first signal line 121 and extends to a position collinear with the second signal line 122 in the non-winding area 123, and then continues to extend along the length direction of the signal line group 120. That is, in the winding area 123, the second signal line 122 bulges along the first direction F1 to avoid the spacer 320. Thus, the original main spacer area 321 in the winding area 123 becomes the first sub-spacer area 322. Optionally, the distance by which the first signal line 121 bends away from the second signal line 122 in the winding area 123 is h, and the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c, and h is greater than or equal to c. The structure in which the first signal line 121 and the second signal line 122 clamp the spacer 320 is formed in the winding area 123, which can effectively prevent the spacer 320 from generating displacement in the first direction F1.

[0067] In some optional embodiments, one spacer 320 is provided for every twenty-four pixel regions 400 on average in the display substrate. For example, in twenty-four pixel regions 400 arranged in two rows and twelve columns, one spacer 320 spans at least thirteen data lines 130 in its length direction, that is, the spacer 320 spans twelve pixel regions 400 in its length direction. The orthographic projection of the spacer 320 on the array substrate 100 has an overlapping region with thirteen data lines 130 and an overlapping region with a set of signal line groups 120. At least eleven of the intersection positions of the thirteen data lines 130 and the set of signal line groups 120 are provided with winding regions 123. In this way, the contact density ratio between the main spacer region 321 and the first sub-spacer region 322 is close to 1:100. The main spacer region 321 and the first sub-spacer region 322 with this ratio of contact density can not only meet the support of the liquid crystal cell thickness but also meet the requirement of no dark spots under external pressing. Of course, the setting of the spacer 320 and the setting of the winding region 123 can be determined according to actual needs. For example, one spacer 320 can be provided for every 23, 24, 25, 26 or 27 pixel regions 400 on average. One spacer 320 spans 12, 13, 14, 15 or 16 data lines 130 in its length direction, that is, the spacer 320 spans 11, 12, 13, 14 or 15 pixel regions 400 in its length direction. The number of winding regions 123 can also be 11, 12, 13, 14 or 15. As long as it satisfies that the contact density of the main spacer region 321 is close to 200μm 2 / mm 2 , the contact density of the first sub-spacer region 322 is close to 20000μm 2 / mm 2 that's fine. The spacer 320 spans multiple data lines 130 in its length direction. Such as Figure 3As shown, when the spacer 320 generates a large displacement in the first direction F1, for example, when the spacer 320 is displaced in the first direction F1 to a position where it does not overlap with the signal line group 120, the data line 130 can still support the spacer 320. That is, when the spacer 320 generates a large displacement in the first direction F1, it will lose the first sub-spacer region 322 formed by the overlap of the main spacer region 321 and the signal line group 120, but the first sub-spacer region 322 formed with the data line 130 will not be lost. Therefore, the large displacement generated by the spacer 320 in the first direction F1 will not scratch the alignment film on the array substrate 100. Optionally, the setting of the spacer 320 can be determined according to requirements. For example, in twenty-four pixel regions 400 arranged in three rows and eight columns, one main spacer region 321 can be set, and six to twelve first sub-spacer regions 322 can be set. Or, in twenty-four pixel regions 400 arranged in four rows and six columns, one main spacer region 321 can be set, and six to twelve first sub-spacer regions 322 can be set, etc. It only needs to meet that the spacer 320 is evenly arranged on the whole surface and the contact density ratio of the main spacer region 321 to the first sub-spacer region 322 is close to 1:100.

[0068] Figure 6 and Figure 7 show the cell thickness of the display substrate with the main spacer region 321 and the first sub-spacer region 322 of different contact densities after the spacer 320 is not displaced and displaced and bears an external force. Figure 6 and Figure 7 The abscissa in is the contact density of the first sub-spacer region 322 (μm 2 / mm 2 ), and the ordinate is the cell thickness (μm). Figure 6 The six lines from top to bottom in represent that the contact density of the main spacer region 321 is 100μm 2 / mm 2 , 150μm 2 / mm 2 , 200μm 2 / mm 2 , 250μm 2 / mm 2 , 300μm 2 / mm 2 , 350μm 2 / mm 2 . Figure 7 The six lines from top to bottom in represent that the contact density of the main spacer region 321 is 350μm 2 / mm 2 , 300μm 2 / mm 2 , 250μm 2 / mm 2 , 200μm2 / mm 2 、 150 μm 2 / mm 2 、 100 μm 2 / mm 2 。 It can be clearly seen that as the contact density of the first sub-spacer region 322 increases, the cell gap of the display substrate after withstanding an external force gradually increases. When the contact density of the main spacer region 321 is 200 μm 2 / mm 2 and the contact density of the first sub-spacer region 322 is 20,000 μm 2 / mm 2 the spacer 320 can provide good support for the cell gap.

[0069] Figure 8 shows the deformation amount of the spacer 320 of the display substrate of the main spacer region 321 and the first sub-spacer region 322 with different contact densities after withstanding an external force when the spacer 320 is displaced. Figure 8 In [it], the abscissa is the contact density of the first sub-spacer region 322 (μm 2 / mm 2 ), and the ordinate is the cell deformation amount (μm). Figure 8 The six lines from top to bottom in [it] respectively represent that the contact density of the main spacer region 321 is 100 μm 2 / mm 2 、 150 μm 2 / mm 2 、 200 μm 2 / mm 2 、 250 μm 2 / mm 2 、 300 μm 2 / mm 2 、 350 μm 2 / mm 2 。 The thickness of the data line 130 is generally between 0.55 μm and 0.65 μm, and the thickness of the signal line group 120 is between 0.65 μm and 0.75 μm. It can be clearly seen that when the contact density of the first sub-spacer region 322 is greater than 15,000 μm 2 / mm 2 and the contact density of the main spacer region 321 is greater than 150 μm 2 / mm 2 the deformation amount of the spacer 320 is significantly smaller than the thickness of the data line 130. At this time, the displacement of the spacer 320 will not scratch the alignment film.

[0070] The second signal line 122 is provided with a via 124 near its crossing position with the data line 130. The second signal line 122 is connected to the liquid crystal capacitor Clc and the storage capacitor Cstg through the via 124. The via 124 is arranged near the crossing position of the second signal line 122 with the data line 130. When light leakage is caused by the via 124, the black matrix 221 can block the light leaking out due to the via 124 to prevent it from affecting the display effect.

[0071] As Figures 9 to 11 shown, in an alternative embodiment, the signal line group 120 includes a first signal line 121. The first signal line 121 controls the connection between the data line 130, the liquid crystal capacitor Clc, and the storage capacitor Cstg, that is, the first signal line 121 controls whether the data line 130 charges the liquid crystal capacitor Clc and the storage capacitor Cstg.

[0072] Another first signal line 121 provides a stable voltage for one end of the liquid crystal capacitor Clc and the storage capacitor Cstg, so as to keep a stable pressure difference between the liquid crystal capacitor Clc and the storage capacitor Cstg, and further keep the liquid crystal molecules at a certain oriented deflection angle. Optionally, a signal line group 120 includes one first signal line 121. Among them, the first signal line 121 controls the on / off of the data line 130 of a row of pixel regions 400, and the first signal line 121 of an adjacent row of pixel regions 400 provides a stable voltage for one end of the liquid crystal capacitor Clc and the storage capacitor Cstg.

[0073] The spacer 320 projects orthogonally onto the array substrate 100 to cover the first signal line 121 in the signal line group 120. That is, within its length range, the spacer 320 projects orthogonally onto the array substrate 100 to cover the first signal line 121.

[0074] For example, the width of the spacer 320 can be a, the width of the first signal line 121 is b, and the alignment deviation between the array substrate 100 and the color filter substrate 200 is c. That is, during the alignment process of the array substrate 100 and the color filter substrate 200, the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c, then a is greater than b. Optionally, a is greater than or equal to b + 2c, that is, the spacer 320 projects orthogonally onto the array substrate 100 to cover the first signal line 121 in the signal line group 120, and the distances from both sides of the first signal line 121 to both sides of the projection of the spacer 320 onto the array substrate 100 are greater than or equal to c. In this way, when a slight deviation occurs during the alignment process of the array substrate 100 and the color filter substrate 200, the width of the overlapping part between the projection of the spacer 320 onto the array substrate 100 and the first signal line 121 is always b. In this way, it can be ensured that the spacer 320 can provide stable support for the liquid crystal layer 300, and further ensure that the liquid crystal layer 300 can maintain a stable thickness, and further ensure the display effect of the display panel.

[0075] The distances from the side of the spacer 320 away from the color filter substrate 200 to the color filter substrate 200 are equal. The overlapping area of the data line 130 and the signal line group 120 forms a plurality of columnar structures 140 protruding towards the color filter substrate 200, and the side of the spacer 320 away from the color filter substrate 200 abuts against some of the columnar structures 140. In this way, the spacer 320 cooperates with the data line 130 and the signal line group 120 to form different spacer areas on itself. The part where the side of the spacer 320 away from the color filter substrate 200 abuts against some of the columnar structures 140 forms the main spacer area 321. The orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the data line 130 or the signal line group 120, and the part that does not overlap with the columnar structure 140 forms the first sub-spacer area 322.

[0076] The part where the orthographic projection of the spacer 320 onto the array substrate 100 overlaps with the area of the array substrate 100 other than the first signal line 121 forms the second sub-spacer area 323. The side of the columnar structure 140 close to the color filter substrate 200 abuts against the spacer 320. The distance between the side of the area on the data line 130 or the signal line group 120 other than the columnar structure 140 close to the color filter substrate 200 and the spacer 320 is f. The distance between the part of the area of the array substrate 100 other than the first signal line 121 and the spacer 320 is g. g > f > 0. In this way, the spacer 320 cooperates with the data line 130 and the signal line group 120 to form the main spacer area 321, the first sub-spacer area 322, and the second sub-spacer area 323 with a step difference. In the normal state, the main spacer area 321 of the spacer 320 provides support for the liquid crystal cell thickness. When the display substrate is pressed, the color filter substrate 200 sinks towards the array substrate 100, and the first sub-spacer area 322 participates in the support of the liquid crystal cell thickness. When the display substrate is pressed strongly, the degree of sinking of the color filter substrate 200 towards the array substrate 100 increases, and at this time, the second sub-spacer area 323 also starts to participate in the support of the liquid crystal cell thickness.

[0077] The signal line group 120 is provided with a plurality of winding areas 123 along its length direction. The winding areas 123 are provided at the positions where at least one signal line group 120 intersects with the data line 130. The orthographic projection of the spacer 320 in the winding area 123 on the array substrate 100 has no overlapping area with the columnar structure 140. For example, the signal line group 120 includes a first signal line 121. The first signal line 121 extends along the length direction of the signal line group 120, i.e., the second direction F2, in the non-winding area 123. In the winding area 123, the first signal line 121 is bent a distance in a direction perpendicular to the length direction of the signal line group 120, and then extends along the length direction of the signal line group 120. After bypassing the columnar structure 140, it bends back and extends to a position collinear with the first signal line 121 in the non-winding area 123, and then continues to extend along the length direction of the signal line group 120. That is, in the winding area 123, the first signal line 121 bulges along the first direction F1 to avoid the spacer 320. In this way, the original main spacer area 321 in the winding area 123 becomes the first sub-spacer area 322. Optionally, the distance by which the first signal line 121 is bent in a direction perpendicular to the length direction of the signal line group 120 in the winding area 123 is h, and the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c, and h is greater than or equal to c.

[0078] There is a spacer 320 provided for every twelve pixel regions 400 on average in the display substrate. For example, among twelve pixel regions 400 arranged in one row and twelve columns, one spacer 320 spans at least thirteen data lines 130 in its length direction, that is, the spacer 320 spans twelve pixel regions 400 in its length direction. The orthographic projection of the spacer 320 on the array substrate 100 has an overlapping region with thirteen data lines 130 and an overlapping region with a group of signal line groups 120. At least eleven of the intersection positions where thirteen data lines 130 intersect with a group of signal line groups 120 are provided with winding regions 123. In this way, the contact density ratio between the main spacer region 321 and the first sub-spacer region 322 is close to 1:100. The main spacer region 321 and the first sub-spacer region 322 with this ratio of contact density can not only meet the support for the liquid crystal cell thickness but also meet the requirement of no dark spots under external pressing. Optionally, the setting of the spacer 320 can be determined according to requirements. For example, in twelve pixel regions 400 arranged in two rows and six columns, one main spacer region 321 can be set, and six to twelve first sub-spacer regions 322 can be set. Or, in twenty-four pixel regions 400 arranged in three rows and four columns, one main spacer region 321 can be set, and six to twelve first sub-spacer regions 322 can be set, etc. It only needs to satisfy that the spacers 320 are evenly arranged on the whole surface and the contact density ratio between the main spacer region 321 and the first sub-spacer region 322 is close to 1:100. Of course, the setting of the above-mentioned spacers 320 and the setting of the winding regions 123 can be determined according to actual needs. For example, one spacer 320 can be provided for 12, 13, 14, 15 or 16 pixel regions 400 on average. One spacer 320 spans 12, 13, 14, 15 or 16 data lines 130 in its length direction, that is, the spacer 320 spans 11, 12, 13, 14 or 15 pixel regions 400 in its length direction. The number of winding regions 123 can also be 11, 12, 13, 14 or 15. As long as it satisfies that the contact density of the main spacer region 321 is close to 200μm 2 / mm 2 , and the contact density of the first sub-spacer region 322 is close to 20000μm 2 / mm 2 That's all right. The spacer 320 spans multiple data lines 130 in its length direction. When the spacer 320 generates a large displacement in the first direction F1, for example, when the spacer 320 is displaced in the first direction F1 to not overlap with the signal line group 120, the data lines 130 support the spacer 320. That is, when the spacer 320 generates a large displacement in the first direction F1, it will lose the first sub-spacer region 322 formed by the overlap of the main spacer region 321 and the signal line group 120, but the first sub-spacer region 322 formed by the overlap with the data lines 130 will not be lost. Therefore, the large displacement generated by the spacer 320 in the first direction F1 will not scratch the alignment film on the array substrate 100.

[0079] As Figure 5 and Figures 12 to 13 shown, in an optional embodiment, the positive projection of the spacer 320 onto the array substrate 100 partially overlaps with the signal line group 120. The distances from the side of the spacer 320 away from the color filter substrate 200 to the color filter substrate 200 are not equal. The spacer 320 includes a main spacer region 321 having a first thickness and a first sub-spacer region 322 having a second thickness, and the first thickness is greater than the second thickness. The positive projection of the main spacer region 321 onto the array substrate 100 has an overlapping region with the data line 130, and the positive projection of the main spacer region 321 onto the array substrate 100 has no overlapping region with the signal line group 120. The positive projection of the main spacer region 321 onto the array substrate 100 covers at least two data lines 130 in the length direction of the spacer 320. The partial positive projection of the first sub-spacer region 322 onto the array substrate 100 overlaps with the data line 130, and the partial positive projection overlaps with the signal line group 120.

[0080] A plurality of winding regions 123 are provided in the signal line group 120 along its length direction. The winding regions 123 are provided at at least one position where the signal line group 120 intersects with the data line 130. In the winding region 123, the signal line group 120 avoids the region where the spacer 320 overlaps with the data line 130. That is, the spacer 320, the signal line group 120, and the data line 130 do not overlap simultaneously. At the same time, the winding region 123 is also provided at the position of the positive projection of the main spacer region 321 onto the array substrate 100, and the signal line group 120 in the winding region 123 avoids the range covered by the positive projection of the main spacer region 321 onto the array substrate 100. If the maximum alignment deviation between the array substrate 100 and the color filter substrate 200 in the first direction F1 is c, then the distance from the signal line group 120 in the winding region 123 to the region where the spacer 320 overlaps with the data line 130 is greater than c, and the distance from the signal line group 120 in the winding region 123 to the region covered by the positive projection of the main spacer region 321 onto the array substrate 100 is greater than c. That is, in the winding region 123, the positive projection of the first sub-spacer region 322 onto the array substrate 100 overlaps with the data line 130, and in the non-winding region 123, the positive projection of the first sub-spacer region 322 onto the array substrate 100 overlaps with the signal line group 120.

[0081] On the display substrate, a spacer 320 is provided for every twenty-four pixel regions 400 on average. For example, among the twenty-four pixel regions 400 arranged in two rows and twelve columns, one spacer 320 spans at least thirteen data lines 130 in its length direction, that is, the spacer 320 spans twelve pixel regions 400 in its length direction. The orthographic projection of the spacer 320 on the array substrate 100 has an overlapping region with thirteen data lines 130 and an overlapping region with a group of signal line groups 120. At each intersection position of the thirteen data lines 130 and a group of signal line groups 120, a winding region 123 is provided. One spacer 320 is provided with a main spacer region 321. In this way, the contact density ratio between the main spacer region 321 and the first sub-spacer region 322 is close to 1:100. The main spacer region 321 and the first sub-spacer region 322 with such a ratio of contact density can not only meet the support of the liquid crystal cell thickness but also meet the requirement of no dark spots under external pressing. Optionally, the setting of the spacer 320 can be determined according to requirements. For example, in the twenty-four pixel regions 400 arranged in three rows and eight columns, one main spacer region 321 can be set, and six to twelve first sub-spacer regions 322 can be set. Or, in the twenty-four pixel regions 400 arranged in four rows and six columns, one main spacer region 321 can be set, and six to twelve first sub-spacer regions 322 can be set, etc. It only needs to satisfy that the spacers 320 are evenly arranged on the whole surface and the contact density ratio between the main spacer region 321 and the first sub-spacer region 322 is close to 1:100. Of course, the setting of the above-mentioned spacer 320 and the setting of the winding region 123 can be determined according to actual needs. One spacer 320 can be provided for every 23, 24, 25, 26, or 27 pixel regions 400 on average. One spacer 320 spans 12, 13, 14, 15, or 16 data lines 130 in its length direction, that is, the spacer 320 spans 11, 12, 13, 14, or 15 pixel regions 400 in its length direction. The number of winding regions 123 can also be 11, 12, 13, 14, or 15. As long as it satisfies that the contact density of the main spacer region 321 is close to 200μm 2 / mm 2 , and the contact density of the first sub-spacer region 322 is close to 20000μm 2 / mm 2That's all. The spacer 320 spans multiple data lines 130 in its length direction. When the spacer 320 generates a large displacement in the first direction F1, for example, when the spacer 320 is displaced in the first direction F1 to a position where it does not overlap with the signal line group 120, the data line 130 can still support the spacer 320. That is, when the spacer 320 generates a large displacement in the first direction F1, it will lose the first secondary spacer region 322 formed by the overlap of the main spacer region 321 and the signal line group 120, but the first secondary spacer region 322 formed by the overlap with the data line 130 will not be lost. At the same time, since the main spacer region 321 of the spacer 320 overlaps with the data line 130, its supporting ability will not be lost due to the displacement of the spacer 320 in the first direction F1. Therefore, the large displacement generated by the spacer 320 in the first direction F1 will not scratch the alignment film on the array substrate 100.
