Thus, the regions illustrated in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.

[0080] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components.

[0081] For high-end large-size display panels, such as high-contrast and high-transmittance products, polarizers with compensation materials can achieve a higher color gamut, better image quality, and improve user experience. Currently, the width of polarizers with compensation materials is limited and cannot meet the usage requirements of large-size products.

[0082] In view of this, an embodiment of the present disclosure provides a display panel, as shown in Figures 1 to 5, wherein Figure 1 is a schematic top view of the display panel provided in the embodiment of the present disclosure, Figure 2 is a schematic cross-sectional view of a display panel provided in the embodiment of the present disclosure, Figure 3 is a schematic cross-sectional view of a display panel provided in the embodiment of the present disclosure, Figure 4 is a schematic view of a stacked layer of the display panel provided in the embodiment of the present disclosure, and Figure 5 is a schematic view of a stacked layer of the display panel provided in the embodiment of the present disclosure; the display panel includes:

[0083] The liquid crystal cell L includes an array substrate L1 and an opposing substrate L2 disposed opposite to each other, and a liquid crystal L3 located between the array substrate L1 and the opposing substrate L2. The liquid crystal cell L has a first side A1 extending along a first direction X and a second side A2 extending along a second direction Y. The maximum length a1 of the first side A1 is greater than the maximum length a2 of the second side A2. The alignment direction J1 of the liquid crystal L3 is parallel to the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0084] The first polarizing assembly P1 is located on the light-emitting side of the liquid crystal cell L. The first polarizing assembly P2 includes a first polarizer P11. It should be noted that the light-emitting side of the liquid crystal cell L may be the side away from the backlight module in the liquid crystal display device.

[0085] The second polarizing assembly P2 is located on the backlight side of the liquid crystal box L. The second polarizing assembly P2 includes: a second polarizer P21; the absorption axis of the second polarizer P21 is perpendicular to the absorption axis of the first polarizer P11; it should be noted that the backlight side of the liquid crystal box L can be the side close to the backlight module in the liquid crystal display device.

[0086] At least one of the first polarizing assembly P1 and the second polarizing assembly P2 further includes a first compensation film B1 , and an optical axis direction J2 of the first compensation film B1 is parallel to the first direction X.

[0087] In the production process of conventional display panels, the polarizer original roll can be cut along the width direction (that is, perpendicular to the extension direction of the polarizer original roll) to obtain the first polarizer component P1 (or the second polarizer component P2) including the first compensation film B1, and the cut first polarizer component P1 (or the second polarizer component P2) including the first compensation film B1 is attached with the optical axis direction of the first compensation film B1 parallel to the short side direction of the liquid crystal box, that is, in the final display panel, the optical axis direction of the first compensation film B1 is parallel to the short side direction of the liquid crystal box L; but when the size of the display panel is larger, for example, a display panel larger than 55 inches, this cutting and attaching method can no longer meet the requirements due to the width limitation of the polarizer original roll; in the embodiment of the present disclosure, the optical axis direction of the first compensation film B1 is parallel to the first direction X, that is, the optical axis direction of the first compensation film B1 is parallel to the long side direction of the liquid crystal box L, and when the display panel is manufactured, the optical axis direction of the first compensation film B1 is parallel to the first direction X, that is, the optical axis direction of the first compensation film B1 is parallel to the long side direction of the liquid crystal box L. When the large-size display panel of the embodiment is opened, the polarizer original roll can be cut along the width direction to obtain the first polarizer component P1 (or the second polarizer component P2) including the first compensation film B1, and the cut first polarizer component P1 (or the second polarizer component P2) including the first compensation film B1 is attached with the optical axis direction of the first compensation film B1 parallel to the long side direction of the liquid crystal box, thereby solving the problem that the conventional polarizer original roll cannot meet the requirements of large-size display panels due to width limitations; in addition, due to the viewing angle compensation requirement, the optical axis direction J2 of the first compensation film B1 needs to be roughly perpendicular to the alignment direction of the liquid crystal to achieve color deviation and brightness improvement at a large viewing angle, and thus in the embodiment of the present disclosure, the alignment direction J1 of the liquid crystal L3 is parallel to the second direction Y, thereby solving the problem that the conventional polarizer original roll cannot meet the requirements of large-size display panels due to width limitations while meeting the color deviation and brightness improvement at a large viewing angle.

[0088] Polarizers are optical film materials that convert natural light into polarized light. In the structure of liquid crystal display panels, polarizers are usually attached to the upper and lower surfaces of the glass substrate with their absorption axes perpendicular to each other. Since liquid crystal molecules have a rod-like structure, the phase difference of incident light in the long axis direction and the short axis direction of the liquid crystal molecules is different. Therefore, under different viewing angles, deviations in contrast and color will occur, resulting in color cast and uneven brightness. Therefore, it is necessary to add a compensation film with a polarization supplementary function (for example, a first compensation film B1 and a second compensation film B2) to the polarizer. As shown in Figure 10, under the positive viewing angle, the absorption axes of the first polarizer P11 and the second polarizer P21 are perpendicular to each other, that is, the absorption axis of the first polarizer P11 and the second polarizer P21 are perpendicular to each other. The transmission axes of the two polarizers P21 are parallel, preventing color shift. At wide viewing angles, the absorption axes of the first and second polarizers P11 and P21 are not perpendicular to each other, and there is a certain offset between the absorption axis of the first polarizer P11 and the transmission axis of the second polarizer P21, resulting in color shift. The use of compensation films can compensate or correct the phase difference at wide viewing angles to a certain extent. The compensation path is shown in Figure 10: the polarized light transmitted through the second polarizer P21 passes through the first compensation film B1 and shifts from point O1 to point O2. After passing through the second compensation film B2, point O2 shifts to a position that coincides with point O3. At this point, the transmission axis of the second polarizer P21 is parallel to the absorption axis of the first polarizer P11, preventing color shift.

[0089] In conjunction with Figures 6 to 9, in which, in Figures 6 to 9, e1 represents the width of the original roll of polarizer, e2 represents the effective width of the original roll of polarizer, e3 represents the long side dimension of the first polarizer P1 (and / or the second polarizer P2) in the small-size display panel 91 (such as less than or equal to 55 inches), e4 represents the short side dimension of the first polarizer P1 (and / or the second polarizer P2) in the large-size display panel 92 (such as greater than 55 inches), the polarizer including the compensation film layer includes the smaller width A as shown in Figures 6 and 8, and the larger width as shown in Figures 7 and 9. Type B, the absorption axis direction of the two polarizer original rolls is horizontal (along the direction of the long side of the polarizer original roll), that is, 0°; the first polarizer P1 attached to the display panel and the second polarizer P2 need to be cut from the polarizer original roll by the manufacturer. Since the absorption axis of the first polarizer P1 (and / or the second polarizer P2) attached to the display panel is usually 0° and 90° when used, there are two corresponding ways to cut the polarizer original roll. The first one is that when the absorption axis direction of the first polarizer P1 (and / or the second polarizer P2) attached to the display panel is 90°, the polarizer original roll The first method of cutting the polarizer is that the long side of the first polarizer component P1 (and / or the second polarizer component P2) corresponds to the short side of the polarizer original roll, as shown in Figures 6 and 7; the second method is that when the absorption axis direction of the first polarizer component P1 (and / or the second polarizer component P2) attached to the display panel is 0°, the polarizer original roll is cut as shown in Figures 8 and 9, and the long side of the first polarizer component P1 (and / or the second polarizer component P2) attached to the display panel corresponds to the long side of the polarizer original roll; the length of the polarizer original roll can be infinitely stretched, but the width of the short side is limited. For example, the width of Type A original roll is 1330m m, with an effective width of 1250mm; the width of the original roll of type B is, for example, 1490mm, and the effective width is 1420mm; the display panel is used in combination with a polarizer containing a compensation film layer as shown in Figures 6 and 7, with an effective width of up to 1250mm, which can correspond to products of 55 inches and below; the embodiment of the present disclosure proposes that the absorption axis of the first polarizing component P1 (and / or the second polarizing component P2) attached to the required display panel is 0°, and the combination usage is shown in Figures 8 and 9, which can correspond to products of 110 inches and below, and can meet the needs of small, medium and extra-large display panels on the current market.

[0090] Vertically Aligned (VA), In-Plane Switching (IPS), and Fringe Field Switching (FFS) display modes all exhibit color shift at large viewing angles. This is because the absorption axes of the first polarizer P11 and second polarizer P21, which were originally perpendicular to each other, have tilted when viewed from a wide viewing angle, causing the angle between them to no longer be perpendicular. As a result, the polarization vector of the outgoing polarized light has a component in the direction of the transmission axis of the upper polarizer, causing light leakage and resulting in color shift.

[0091] In a possible implementation manner, the size of the display panel provided by the embodiment of the present disclosure may be greater than 55 inches; in a possible implementation manner, the size of the display panel provided by the embodiment of the present disclosure may be 55 inches to 110 inches.

[0092] In a possible implementation, the alignment direction J1 of the liquid crystal L3 may be the arrangement direction of the liquid crystal L3 when no power is applied, or may be the initial arrangement direction of the liquid crystal L3.

[0093] In a possible embodiment, referring to FIG. 2 and FIG. 4 , the first compensation film B1 is located in the first polarizing assembly P1 and on the side of the first polarizer P1 facing the liquid crystal cell L; the absorption axis of the first polarizer P11 is parallel to the first direction X, and the absorption axis of the second polarizer P21 is parallel to the second direction Y.

[0094] In a possible embodiment, referring to Figures 3 and 5, the first compensation film B1 is located in the second polarizing assembly P2 and on the side of the second polarizer P21 facing the liquid crystal box L; the absorption axis of the first polarizer P11 is parallel to the second direction Y, and the absorption axis of the second polarizer P21 is parallel to the first direction X.

[0095] In a possible implementation, referring to FIG. 1 to FIG. 5 , one of the first polarizing assembly P1 and the second polarizing assembly P2 further includes: a second compensation film B2 located on a side of the first compensation film B1 away from the liquid crystal cell L.

[0096] In a possible embodiment, referring to Figures 11A to 11G and Figures 12A to 12C, Figure 11A is one of the top views of the array substrate provided in an embodiment of the present disclosure, Figure 11B is a schematic diagram of a single film layer of the second conductive layer in Figure 11A, Figure 11C is a schematic diagram of a single film layer of the first metal layer in Figure 11A, Figure 11D is a schematic diagram of a single film layer of the second metal layer in Figure 11A, Figure 11E is a schematic diagram of a single film layer of the active layer in Figure 11A, and Figure 11F is a schematic diagram of a single film layer of the first conductive layer in Figure 11A.

The array substrate includes: a substrate 1, and a first conductive layer 2 located on one side of the substrate 1; the first conductive layer 2 has a plurality of slits F; the angle β1 formed by the slits F with the first direction X ranges from 0° to 45°, and the liquid crystal L is a negative liquid crystal. Specifically, the angle β1 formed by the slits F with the first direction X ranges from 0° to 30°; specifically, the angle β1 formed by the slits F with the first direction X can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, or 45°.

[0097] In the embodiment of the present disclosure, the angle β1 formed by the slit F and the first direction X ranges from 0° to 45°. When the display panel is powered on, the direction of the electric field lines is perpendicular to the direction of the slit F. For example, when the angle β1 formed by the slit F and the first direction X is 0°, the direction of the electric field lines is 90°; the negative liquid crystal molecules rotate along the direction of the electric field lines, that is, the initial arrangement direction of the liquid crystal molecules is 90° (that is, the rubbing direction during rubbing alignment is 90°), thereby making the alignment direction of the liquid crystal L3 parallel to the second direction Y, and cooperating with the optical axis direction of the first compensation film B1, thereby achieving color deviation and brightness improvement at a large viewing angle; moreover, the liquid crystal L is a negative liquid crystal with a high transmittance, which can make the display panel have a higher brightness.

[0098] In a possible embodiment, referring to Figures 11A to 11G and Figures 12A to 12C, the array substrate further includes: a second conductive layer 3 located on the side of the first conductive layer 2 facing the substrate 1, the second conductive layer 3 including: a plurality of pixel electrodes 30 distributed in an array; the first conductive layer 2 includes a plurality of slit groups F0, the orthographic projection of the slit group F0 on the substrate 1 overlaps with the orthographic projection of the pixel electrode 30 on the substrate 1; specifically, the first conductive layer 2 can be provided with a slit group F0 in an area corresponding to each pixel electrode 30, and the slit group F0 and the pixel electrode 30 can correspond one to one; the slit group F0 includes: at least two sub-slit groups F00 distributed along the second direction Y, and the angle β2 formed by the slits F of two adjacent sub-slit groups F00 is an acute angle. Specifically, the angle β2 formed by the slits F of two adjacent sub-slit groups F00 ranges from 0° to 60°; the angle β2 formed by the slits F of two adjacent sub-slit groups F00 can be 0°, 10°, 20°, 30°, 40°, 50°, or 60°.

[0099] In a possible implementation, the first conductive layer 2 may be a common electrode layer.

[0100] In one possible embodiment, the first conductive layer 2 may specifically be a transparent electrode layer, and the material of the first conductive layer 2 may specifically include metal oxides (for example, indium tin oxide, indium-doped zinc oxide (AZO), fluorine-doped tin oxide (AZO), aluminum-doped zinc oxide (AZO), indium-doped cadmium oxide, etc. In one possible embodiment, the second conductive layer 3 may specifically be a transparent electrode layer, and the material of the second conductive layer 3 may specifically include metal oxides (for example, indium tin oxide, indium-doped zinc oxide (AZO), fluorine-doped tin oxide (AZO), aluminum-doped zinc oxide (AZO), indium-doped cadmium oxide, etc.

[0101] In one possible embodiment, as shown in Figures 13A-13G , the array substrate includes: a substrate 1; and a first conductive layer 2 located on one side of the substrate 1; the first conductive layer 2 has a plurality of slits F; the angle β3 formed between the slits F and a first direction X ranges from 45° to 90°, and the liquid crystal is positive liquid crystal. Specifically, the angle β1 formed between the slits F and the first direction X ranges from 60° to 90°; specifically, the angle β1 formed between the slits F and the first direction X can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, or 90°.

[0102] In the embodiment of the present disclosure, the angle β3 formed by the slit F and the first direction X is in the range of 45° to 90°. When the display panel is powered on, the direction of the electric field lines is perpendicular to the direction of the slit F. For example, when the angle β1 formed by the slit F and the first direction X is 90°, the direction of the electric field lines is 0°. The positive liquid crystal molecules rotate perpendicular to the direction of the electric field lines, that is, the initial arrangement direction of the liquid crystal molecules is 90° (that is, the rubbing direction during rubbing alignment is 90°), thereby making the alignment direction of the liquid crystal L3 parallel to the second direction Y. Combined with the optical axis direction of the first compensation film B1, color deviation and brightness improvement at a large viewing angle can be achieved. Moreover, in the embodiment of the present disclosure, the angle β3 formed by the slit F and the first direction X is in the range of 45° to 90°, the liquid crystal is positive liquid crystal, and the structure of the array substrate can be manufactured based on the currently existing process, which is simpler to manufacture.

[0103] In one possible embodiment, as shown in Figures 13A-13G , the array substrate further includes: a second conductive layer 3 located on the side of the first conductive layer 2 facing the substrate 1; the second conductive layer 3 includes: a plurality of pixel electrodes 30 distributed in an array; the first conductive layer 2 includes a plurality of slit groups F0, wherein the orthographic projections of the slit groups F0 on the substrate 1 overlap with the orthographic projections of the pixel electrodes 30 on the substrate 1; the slit groups F0 include: at least two sub-slit groups F00 distributed along the second direction Y, wherein the angle β4 formed by the slits of two adjacent sub-slit groups F00 is an obtuse angle. Specifically, the angle β4 formed by the slits F of two adjacent sub-slit groups F00 ranges from 90° to 180°; and the angle β2 formed by the slits F of two adjacent sub-slit groups F00 can be 90°, 100°, 120°, 130°, 140°, 150°, 160°, 170°, or 180°.

[0104] In one possible embodiment, the material of the first compensation film B1 may include a cyclic olefin copolymer resin, and optionally, may be a +A film layer. In another possible embodiment, the material of the second compensation film B2 includes liquid crystal, and optionally, may be a +C film layer. Optionally, the +C film and the +A film are sequentially attached to the PVA film layer in the first polarizing assembly P1 (and / or the second polarizing assembly P2).

[0105] The display panel provided by the embodiment of the present disclosure is further illustrated below by combining different liquid crystal types and the first compensation film B1 being located in different polarizing components.

[0106] For example, as shown in FIG11A and FIG4 , the first compensation film B1 is located in the first polarizing element P1, the liquid crystal is negative liquid crystal, and the angle β1 formed by the slit F and the first direction X ranges from 0° to 45°. That is, the slit F is generally arranged horizontally. Since the direction of the electric field line is perpendicular to the opening direction of the slit F, that is, 90°, and the negative liquid crystal molecules rotate along the direction of the electric field line, that is, the initial arrangement direction of the liquid crystal molecules is 90°, the optical axis direction J2 of the first compensation film B1 is parallel to the first direction X, that is, 0°, and the alignment direction of the liquid crystal L is perpendicular to the optical axis direction J2 of the first compensation film B1. This can achieve color shift and brightness improvement at a wide viewing angle and is suitable for products of 110 inches and below, breaking through the current width limit of polarizers containing compensation films for medium and large display panels.

[0107] For another example, as shown in FIG11A and FIG5 , the first compensation film B1 is located in the second polarizer P2 , the liquid crystal is negative liquid crystal, and the angle β1 formed between the slit F and the first direction X ranges from 0° to 45°. That is, the slit F is generally arranged horizontally. Since the direction of the electric field lines is perpendicular to the opening direction of the slit F, that is, 90°, and the negative liquid crystal molecules rotate along the direction of the electric field lines, that is, the initial arrangement direction of the liquid crystal molecules is 90°, the optical axis direction J2 of the first compensation film B1 is parallel to the first direction X, that is, 0°, and the alignment direction of the liquid crystal L is perpendicular to the optical axis direction J2 of the first compensation film B1. This can achieve color shift and brightness improvement over a wide viewing angle, and is applicable to products of 110 inches and below, breaking through the current width limitation of polarizers containing compensation films for medium and large display panels.

[0108] For example, as shown in FIG13A and FIG4 , the first compensation film B1 is located in the first polarizing element P1, the liquid crystal is positive liquid crystal, and the angle β3 formed by the slit F and the first direction X ranges from 45° to 90°. That is, the slit F is generally arranged longitudinally, for example, at 90°. Since the direction of the electric field lines is perpendicular to the opening direction of the slit F, that is, 0°, and the positive liquid crystal molecules rotate perpendicular to the direction of the electric field lines, that is, the initial arrangement direction of the liquid crystal molecules is 90°, the optical axis direction J2 of the first compensation film B1 is parallel to the first direction X, that is, 0°, and the alignment direction of the liquid crystal L is perpendicular to the optical axis direction J2 of the first compensation film B1. This can achieve color shift and brightness improvement at a wide viewing angle and is applicable to products of 110 inches and below, breaking through the current width limitation of polarizers containing compensation films for medium and large display panels.

[0109] For another example, as shown in Figures 13A and 5, the first compensation film B1 is located in the second polarizing component P2, the liquid crystal is positive liquid crystal, and the angle β3 formed by the slit F and the first direction X ranges from 45° to 90°, that is, the slit F is roughly arranged longitudinally, for example, at 90°. Since the direction of the electric field line is perpendicular to the opening direction of the slit F, that is, 0°, and the positive liquid crystal molecules rotate perpendicular to the direction of the electric field line, that is, the initial arrangement direction of the liquid crystal molecules is 90°, the optical axis direction J2 of the first compensation film B1 is parallel to the first direction X, that is, 0°, and the orientation direction of the liquid crystal L is perpendicular to the optical axis direction J2 of the first compensation film B1, which can achieve color deviation and brightness improvement at a large viewing angle, and is compatible with products of 110 inches and below, breaking through the current width restrictions of polarizers containing compensation films for medium and large display panels.

[0110] In one possible embodiment, referring to Figures 11A-11G and 13A-13G, the array substrate further includes: a first metal layer 4 located on the side of the first conductive layer 2 facing the substrate 1, and a second metal layer 5 located between the first metal layer 4 and the first conductive layer 2. The first metal layer 4 includes: a plurality of data lines 40 extending along the second direction Y, and a plurality of transistor control electrodes; the second metal layer 5 includes: a plurality of gate lines 50 extending along the first direction X, a transistor first electrode TB1, and a transistor second electrode TB2. Specifically, the transistor control electrode can be a transistor gate, the transistor first electrode TB1 can be a transistor source, and the transistor second electrode TB2 can be a transistor drain.

[0111] Due to the coupling capacitance between the data line 40 and the electrode on its upper layer (for example, the first conductive layer 2), the load on the data line 40 is relatively large. In order to reduce the coupling capacitance between the two, in the related art, a thicker organic insulating layer is provided between the pixel electrode 30 and the electrode on its upper layer (for example, the first conductive layer 2) to reduce the coupling capacitance between the two. However, this method increases the process of the display panel and increases the production cost of the display panel. In the embodiment of the present disclosure, the array substrate further includes: a first metal layer 4 located on the side of the first conductive layer 2 facing the substrate 1, and a second metal layer 5 located between the first metal layer 4 and the first conductive layer 2; the first metal layer 4 includes: a plurality of data lines 40 extending along the second direction Y, and a plurality of transistor control electrodes; the second metal layer 5 includes: a plurality of gate electrodes extending along the first direction X line 50, the first electrode TB1 of the transistor, and the second electrode TB2 of the transistor, that is, the data line 40 is set in a layer closer to the substrate 1, so that there are more insulating layers between the data line 40 and the electrode on its upper layer (for example, the first conductive layer 2), thereby making the distance between the data line 40 and the electrode on its upper layer (for example, the first conductive layer 2) larger, thereby reducing the coupling capacitance between the data line 40 and the electrode on its upper layer (for example, the first conductive layer 2), reducing the load caused by the coupling capacitance on the data line 40, and helping to improve the pixel charging rate and reduce the temperature of the driving chip (IC); and, compared with the related art, since the embodiment of the present disclosure does not need to add an organic insulating layer to reduce the coupling capacitance between the data line 40 and the electrode on its upper layer (for example, the first conductive layer 2), the process complexity will not be increased.
