Description

[Technical Field]

[0001] TECHNICAL FIELD This application relates to the field of display technology, and more particularly to display devices. [Background technology]

[0002] As handheld computer products become narrower in frame, the requirements for module-to-chassis integration are becoming increasingly high. Due to factors such as product design tolerances and assembly tolerances, module-to-chassis integration problems often occur in narrow-frame products, with abnormal noise being a particularly prominent issue.

[0003] In the process of researching and implementing the prior art, the inventors of the present application discovered that the cause of the noise caused by interference between the module and chassis was a step between the polarizer attached to the color film substrate and the cell tape attached to the color film substrate. Due to assembly tolerances and a narrow frame, the overlap width between the polarizer and the chassis was insufficient, and when the entire machine was opened, closed, or shook, the edges of the polarizer and the chassis rubbed against each other, causing the noise.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The invention according to the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. However, it is clear that the described embodiments are only some of the embodiments of the present application and not all of the embodiments. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present application without any creative effort fall within the scope of protection of the present application. Furthermore, it should be understood that the specific embodiments described herein are merely for the purpose of illustrating and explaining the present application and are not intended to limit the present application. In this application, unless otherwise specified, directional terms such as "upper" and "lower" generally refer to the actual use or working state of the device, specifically the upper and lower parts in the direction of the drawings in the accompanying drawings, while directional terms such as "inner" and "outer" refer to the contour of the device. Terms such as "first," "second," and "third" are used only as identifiers and do not impose numerical requirements or determine an order.

[0027] 1, a related art narrow-bezel display device, such as a handheld computer, includes a backlight module F1, a display module F2, a border shielding tape F3, a bottom case F4, and a front case F5. The display module F2 includes an array substrate F21, a color film substrate F22, an upper polarizer F23, and a lower polarizer F24. The upper polarizer F23 is disposed on the color film substrate F22, and the lower polarizer F24 is disposed on the side of the array substrate F21 away from the color film substrate F22. The border shielding tape F3 is attached to the side of the color film substrate F22 away from the array substrate F21 and is located on one side of the upper polarizer F23, with a step between the upper polarizer F23 and the border shielding tape F3.

[0028] Due to the requirement for a narrow frame and the assembly tolerance between the first polarizer and the chassis, the overlap width between the front case F5 and the upper polarizer F23 is insufficient, and when the chassis is opened or closed, the edges of the upper polarizer F23 and the front case F5 rub against each other, causing noise.

[0029] Here, since electronic circuits such as a flexible circuit board are provided on the ground side of the module, when the module and chassis are opened and closed, referring to Figures 2 and 3, the ground side of the module is affected by the flexible circuit board, etc., and the upper polarizer F23 and the front case F5 of the chassis are likely to move relative to each other, while the other sides (the ceiling side and the left and right sides) are less likely to move relative to each other, so it should be understood that abnormal noise often occurs on the ground side of the module.

[0030] In addition, the tolerance of the outer shape of the module (backlight module + display module) is ±0.3 mm, the tolerance of the attachment of the upper polarizer F23 is ±0.2 mm, the tolerance of the cavity of the bottom case F4 is ±0.2 mm, the tolerance of the inner diameter of the front case F5 is ±0.15 mm, and the assembly tolerance of the module and bottom case F4 is ±0.5 mm, calculated using the root mean square method.

number

[0031] In order to solve the above problem, the display device according to the embodiment of the present application supports the front cover by adding a support structure to the opposing substrate, and even if the front cover comes off the first polarizer when the front cover moves relative to the first polarizer, the front cover is supported by the support structure, thereby reducing the friction of the front cover against the edge of the first polarizer.

[0032] The embodiments of the present application provide a display device, which will be described in detail below. Note that the order of the description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0033] 4 and 5, which illustrate a display device 100 according to an embodiment of the present application. While the following description will discuss a case in which the display device 100 is applied to a notebook computer, the embodiment is not limited thereto. For example, in addition to notebook computers, the display device 100 can also be applied to mobile phones, tablet personal computers (PCs), personal digital assistants (PDAs), portable multimedia players (PMPs), televisions, game consoles, wristwatch-type electronic devices, head-mounted displays, personal computer displays, smartphones, vehicle navigation systems, vehicle dashboards, digital cameras, video cameras, outdoor signs, electronic display panels, medical equipment, testing equipment, various home appliances such as refrigerators and washing machines, or Internet of Things devices. Hereinafter, detailed embodiments will be described with reference to the accompanying drawings.

[0034] The display device 100 may have a rectangular shape in a top plan view, but the embodiment is not limited thereto. For example, the display device 100 may have a rectangular shape with perpendicular or chamfered corners or other shapes in a top plan view. The display device 100 may also have two short sides and two long sides in a plan view.

[0035] The display device 100 includes a display panel 10 , a first polarizer 21 , a support structure 30 and a front cover 41 .

[0036] The display panel 10 includes an array substrate 11 and a counter substrate 12 disposed opposite the array substrate 11. A first polarizer 21 is disposed on the side of the counter substrate 12 remote from the array substrate 11. A support structure 30 is disposed on the side of the counter substrate 12 remote from the array substrate 11, and is located on the side of the first polarizer 21 closer to the edge of the counter substrate 12. A front cover 41 is disposed on the side of the support structure 30 and the first polarizer 21 remote from the array substrate 11, and covers the edge region of the first polarizer 21 and the support structure 30.

[0037] In a direction perpendicular to the plate surface of the display panel 10, the distance from the surface of the support structure 30 away from the array substrate 11 to the surface of the counter substrate 12 away from the array substrate 11 is a first distance d1, and the distance from the surface of the first polarizer 21 away from the array substrate 11 to the surface of the counter substrate 12 away from the array substrate 11 is a second distance d2. The first distance d1 is equal to or greater than the second distance d2.

[0038] Here, the direction perpendicular to the surface of the display panel 10 is the thickness direction of the display panel 10.

[0039] The display device 100 of the present embodiment adds a support structure 30 to the opposing substrate, where the first distance d1 is greater than or equal to the second distance d2, i.e., the support structure 30 is higher than the first polarizer 21 or is flush with the first polarizer 21, thereby supporting the front cover 41, and even if the front cover 41 comes off the first polarizer 21 when the front cover 41 and the first polarizer 21 move relative to each other, the front cover 41 is supported by the support structure 30, and as a result, rubbing of the front cover 41 against the edge of the first polarizer 21 is reduced.

[0040] It should be understood that the higher the support structure 30, i.e., the larger the first distance d1, the farther the front cover 41 is from the first polarizer 21 in the thickness direction of the display panel 10, thereby reducing the relative movement and rubbing of the front cover 41 against the first polarizer 21.

[0041] Alternatively, the first distance d1 is greater than the second distance d2 by at most 0.05 mm. For example, the difference between the first distance d1 and the second distance d2 may be 0.05 mm, 0.04 mm, 0.03 mm, 0.02 mm, 0.01 mm, or 0 mm.

[0042] The difference between the first distance d1 and the second distance d2 is set to 0.05 mm or less so as to reduce the gap width between the first polarizer 21 and the front cover 41 and improve the overall flatness and sealing effect of the display device 100. When the first distance d1 is equal to the second distance d2, the support structure 30 is flush with the first polarizer 21, and the overall flatness, sealing effect, and stability of the display device 100 are best.

[0043] In some embodiments, in order to improve the protection performance of the first polarizer 21, the protection layer can be fixedly connected to the first polarizer 21 to form a composite first polarizer 21.

[0044] Alternatively, in some embodiments, a protective layer is added to the side of the first polarizer 21 away from the counter substrate 12, and the edge of the protective layer is flush with the first polarizer 21. Based on this, the first distance d1 is greater than the second distance d2, and the support structure 30 may be flush with the protective layer or slightly higher than the protective layer.

[0045] Optionally, the protective layer may be a cover plate or a stiffening layer.

[0046] Furthermore, it should be understood that the support structure 30 is fixed to the opposing substrate 12 side, and the support structure 30 can be flexibly set to suit opposing substrates 12 of different sizes and shapes, thereby providing greater adaptability and reducing the possibility of interference with the assembly of the support structure 30 compared to when the support structure 30 is fixed to the front cover 41.

[0047] Optionally, the support structure 30 has a support length L1 in the short side direction, the support length L1 being greater than 0.06 mm, or 0.66 mm or greater.

[0048] It should be understood that if the design value of the overlap width between the front cover 41 and the first polarizer 21 is 0.6 mm, due to assembly tolerance requirements, the support length L1 can overcome the tolerance of 0.66 mm if it is greater than 0.06 mm. Based on this, the support length L1 of the support structure 30 can be appropriately adjusted according to the design value of the overlap width between the front cover 41 and the first polarizer 21.

[0049] In the embodiment of the present application, the front cover 41 covering the edge region of the first polarizer 21 means that the front cover 41 can cover at least one edge region of the first polarizer 21, for example, the front cover 41 can cover the edge regions on all four sides of the periphery of the first polarizer 21, the edge regions on three adjacent sides, the edge regions on two adjacent sides, or of course the edge region on one side. Here, the present application takes as an example a case where the front cover 41 covers the edge regions on all four sides of the periphery of the first polarizer 21.

[0050] In one embodiment of the present application, the front cover 41 includes a cover body 41a and a reinforcing rib 41b, the cover body 41a envelops the reinforcing rib 41b, and the hardness of the reinforcing rib 41b is greater than that of the cover body 41a.

[0051] Here, in order to increase the rigidity of the front cover 41, reinforcing ribs 41b with high hardness are provided inside the cover body of the front cover 41. When the front cover 41 and the first polarizer 21 move relative to each other due to opening and closing operations, the front cover 41 with high rigidity is less likely to sag and become distorted, and vertical rubbing between the front cover 41 and the first polarizer 21 can be reduced.

[0052] Alternatively, the material of the reinforcing rib 41b may be a hard material such as an alloy.

[0053] In some embodiments, the front cover 41 may be made solely from plastic or a metal alloy, or may be made from other materials.

[0054] For example, in some embodiments, the front cover 41 may be formed from a composite material of mixed hard particles containing a resin material. The front cover 41 made of mixed hard particles has high rigidity, which can reduce vertical friction between the front cover 41 and the first polarizer 21 and increase the wear resistance of the front cover 41. Furthermore, the addition of hard particles can polish the exterior surface of the front cover 41, reducing the effect on specular reflection. Optionally, the hard particles may be ceramic particles, quartz particles, or other materials.

[0055] The display panel 10 is a liquid crystal display panel. Liquid crystal is disposed between an array substrate 11 and a counter substrate 12. The counter substrate 12 is a color film substrate, i.e., a color film layer is fixedly connected to the counter substrate 12. In some embodiments, the color film layer may be fixedly connected to the array substrate 11.

[0056] Here, the array substrate 11 includes a cell region and a bonding region BD that are arranged opposite to the opposing substrate 12, and the bonding region BD is located outside the opposing substrate 12 and is used for bonding a circuit board that provides related signals to the display panel 10.

[0057] The display device 100 further includes a backlight module 50 and a second polarizer 22, the second polarizer 22 being disposed on the side of the array substrate 11 that is remote from the counter substrate 12. The backlight module 50 is disposed on the side of the second polarizer 22 that is remote from the display panel 10.

[0058] The backlight module 50 provides a backlight source for the display panel 10. The backlight module 50 may be a direct-type backlight or a side-in type backlight.

[0059] The display device 100 further includes a border shielding layer 60, which is disposed around the periphery of the first polarizer 21. One side of the border shielding layer 60 covers the side of the counter substrate 12 away from the array substrate 11, and the other side of the border shielding layer 60 is folded along the side of the backlight module 50 to the rear surface of the backlight module 50.

[0060] Alternatively, the border shielding layer 60 may be a black tape, a light-shielding tape with electromagnetic shielding, or other material with a light-shielding effect.

[0061] Optionally, the first polarizer 21 is disposed in a central region of the counter substrate 12 so that the edge portions on the four sides of the periphery of the counter substrate 12 are exposed. Meanwhile, a portion of the border shielding layer 60 is attached to cover the edge portions on the four sides of the periphery of the counter substrate 12. However, the embodiments of the present application are not limited thereto. For example, in some embodiments, the first polarizer 21 may be flush with the side surface of the counter substrate 12, and in this case, the border shielding layer 60 is attached to the side surface of the counter substrate 12 or the exposed region of the array substrate 11. In other words, the border shielding layer 60 is not disposed on the light-emitting surface of the counter substrate 12.

[0062] The display device 100 further includes a bottom case 42, in which a receiving groove 40a is provided. The backlight module 50, the display panel 10, and the border shielding layer 60 are provided in the receiving groove 40a. The front cover 41 covers the border shielding layer 60, and the front cover 41 is connected to the side wall of the bottom case 42.

[0063] In one embodiment of the present application, the support structure 30 is located at least on the side of the first polarizer 21 that is closer to the bonding region BD of the array substrate 11 .

[0064] Since the display device 100 has the greatest risk of generating abnormal noise on the ground side, by installing the support structure 30 at least in the area on the ground side, it is possible to minimize rubbing between the front cover 41 and the first polarizer 21 and reduce the risk of abnormal noise generation.

[0065] It should be understood that placing the support structure 30 in an area prone to friction minimizes the possibility of abnormal noise. Therefore, to reduce the overall possibility of abnormal noise, the support structure 30 may be placed on all four sides of the periphery of the counter substrate 12. Furthermore, the larger the area occupied by the support structure 30, the lower the possibility of abnormal noise.

[0066] Optionally, in one embodiment of the present application, the support structure 30 includes a support portion 31. In a top view of the display device 100 (FIG. 5), the support portion 31 extends and protrudes in a direction from the first polarizer 21 toward the edge of the counter substrate 12.

[0067] The support portion 31 extends and protrudes from the first polarizer 21, i.e., the support portion 31 is connected to the first polarizer 21, thereby making the planar distance between the support structure 30 and the first polarizer 21 zero and further reducing the possibility of rubbing between the front cover 41 and the edge of the first polarizer 21. At the same time, tolerances involved in assembling the support structure 30 itself and to other components are avoided; i.e., the support portion 31 and the first polarizer 21 are assembled integrally, improving assembly convenience.

[0068] Alternatively, the support structure 31 may be integrally formed with the first polarizer 21 using the same material. That is, the support structure 31 and the first polarizer 21 are an integral structure formed by cutting the same polarizer blank. This simplifies the difficulty of assembling the module, avoids assembly tolerances between the support structure 30 and the first polarizer 21, and makes it easier to achieve flush heights between the support structure 30 and the first polarizer 21.

[0069] Optionally, in some embodiments, the material of the support 31 may be different from that of the first polarizer 21 .

[0070] Optionally, the first polarizer 21 is attached to the counter substrate 12 by a layer of optical adhesive. If the optical adhesive is fixedly connected to the first polarizer 21, the support structure 30 is an extended portion of the first polarizer 21. If the first polarizer 21 is attached to the counter substrate 12 by additional optical adhesive, the support structure 30 further comprises an optical adhesive.

[0071] It should also be understood that the number and size of the support structures 30 can be flexibly set according to the size of the display panel 10. For example, if the size of the display panel 10 is small, a single support structure 30 can be installed, and the support structure 30 can be installed in the middle region on the ground side. If the size of the display panel 10 is large, multiple support structures 30 can be installed, and the support structures 30 can be installed in the middle region on the ground side and in the edge regions on both sides. Below, an example in which three support structures 30 are installed on the ground side as shown in Figure 4 will be described.

[0072] In one embodiment of the present application, in a top view of the display device 100, the boundary of the support structure 30 on the side closer to the counter substrate 12 is separated from the boundary of the counter substrate 12 by an empty space 3a.

[0073] An avoidance opening 6a is provided on the side of the border shielding layer 60 closer to the first polarizer 21, and the support structure 30 is provided within the avoidance opening 6a. In a top view of the display device 100, in the side edge region of the counter substrate 12 corresponding to the support structure 30, the border shielding layer 60 is continuously attached to the counter substrate 12 with an empty space 3a therebetween.

[0074] It should be understood that since the support structure 30 does not cover the entire opposing substrate 12 in the extension direction of the short side of the display panel 10, an empty space 3a is formed in the uncovered area of ​​the opposing substrate 12, and the corresponding avoidance opening 6a does not cut the portion of the border shielding layer 60 located on the upper surface of the opposing substrate, and the formation of the empty space 3a increases the attachment area of ​​the border shielding layer 60, improves the attachment stability and the overall coverage, and improves the light-blocking effect; and secondly, the border shielding layer 60 corresponds to the entire upper surface of the opposing substrate 12, making it continuous, thereby facilitating overall attachment and improving attachment efficiency.

[0075] Optionally, in some embodiments of the present application, the boundary of the support structure 30 on the side closer to the counter substrate 12 overlaps with the boundary of the counter substrate 12 in a top view of the display device 100 .

[0076] Since the boundaries of the support structure 30 and the opposing substrate 12 overlap, the planar size of the support structure 30 increases, the support area of ​​the support structure 30 against the front cover 41 improves, and the possibility of abnormal noise generation decreases.

[0077] Alternatively, the support structures 30 are provided equidistantly in the ground side region of the display device 100. The width of the support structures 30 in the length direction of the display panel 10 is 10 mm to 20 mm, and may be, for example, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm.

[0078] It should be understood that the planar size of the support structure 30 can be appropriately adjusted depending on the requirements for attaching the border shielding layer 60 and the support for the front cover 41, and the embodiment of the present application is not strictly limited.

[0079] The embodiment shown in Figures 6 and 7 is different from that shown in Figures 4 and 5. In Figures 6 and 7, only the parts that are different from the above-described embodiment will be described to avoid redundant explanation.

[0080] 6 and 7, in one embodiment of the present application, the support structure 30 is installed independently of the first polarizer 21.

[0081] That is, the support structure 30 and the first polarizer 21 are fixed to the opposing substrate 12 in separate steps. Here, since the support structure 30 and the first polarizer 21 are installed independently of each other, the support structure 30 can advantageously have a wider range of materials and structures to choose from, which provides greater flexibility and functionality.

[0082] In one embodiment of the present application, the distance between the support structure 30 and the first polarizer 21 is 0.15 mm or less.

[0083] Setting the distance between the support structure 30 and the first polarizer 21 to 0.15 mm or less ensures that the front cover 41 and the first polarizer 21 do not rub against each other due to vertical misalignment. Here, the smaller the distance between the support structure 30 and the first polarizer 21, the better the effect of preventing the rubbing against each other.

[0084] Alternatively, the distance between the support structure 30 and the first polarizer 21 may be 0 mm, 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.10 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm or 0.15 mm.

[0085] In one embodiment of the present application, the support structure 30 includes a support portion 31 and an adhesive layer 32 , and the support portion 31 is attached to the opposing substrate 12 by the adhesive layer 32 .

[0086] Here, the adhesive layer 32 is an adhesive layer, and the support structure 30 is fixed to the counter substrate 12 side by an adhesive. In some embodiments, the adhesive layer 32 may be a welding layer, and the support structure 30 may be fixed to the counter substrate 12 side by welding.

[0087] In addition, the support structure 30 can be used as a positioning structure for the attachment operation of the first polarizer 21, i.e., the attachment operation can be performed by contacting the support structure 30 using the support structure 30 as a reference, thereby reducing assembly tolerances.

[0088] Alternatively, the support 31 may be made of a flexible material. The support 31 may be made of a flexible material, such as PET, rubber, or foamed cotton, which provides excellent cushioning and absorbs external stress. When the support 31 is slightly higher than the first polarizer 21 (when the difference between the first distance d1 and the second distance d2 is 0.05 mm or less), the front cover 41 presses the support 31 slightly downward, causing the support 31 to deform slightly and improving the sealing effect. Furthermore, the downward pressure of the front cover 41 firmly bonds the adhesive layer 32 to the support 31 and the opposing substrate 12, improving the strength of the bond.

[0089] Alternatively, the elastic modulus of the support part 31 is 10 MPa to 4000 MPa so that the support part 31 has both cushioning properties and good support. For example, the elastic modulus of the support part 31 may be 10 MPa, 50 MPa, 100 MPa, 200 MPa, 300 MPa, 400 MPa, 500 MPa, 600 MPa, 700 MPa, 800 MPa, 900 MPa, 1000 MPa, 1500 MPa, 2000 MPa, 2500 MPa, 3000 MPa, 3500 MPa, or 4000 MPa.

[0090] In some embodiments of the present application, the material of the support portion 31 may be a hard material such as a ceramic or an alloy, etc. The support portion 31 uses a support material to enhance support and wear resistance.

[0091] Optionally, the elastic modulus of the support 31 is higher than that of the first polarizer 21, i.e., the hardness of the support structure 30 is greater than that of the first polarizer 21, and the support structure 30 has good support properties so as to reduce the possibility of the front cover 41 being pressed downward.

[0092] Optionally, the modulus of elasticity of the support portion 31 is 70 Gpa or more, for example, 70 Gpa, 71 Gpa, 72 Gpa, 73 Gpa, 74 Gpa, 75 Gpa, 76 Gpa, 77 Gpa, 78 Gpa, 79 Gpa, 80 Gpa, 90 Gpa, 100 Gpa, 110 Gpa, 120 Gpa, 130 Gpa, 140 Gpa, 150 Gpa, 160 Gpa, 170 Gpa, 180 Gpa, 190 Gpa or 200 Gpa.

[0093] The embodiment shown in Figures 8 and 9 is different from that shown in Figures 6 and 7. In Figures 8 and 9, only the parts that are different from the above-described embodiment will be described to avoid redundant explanation.

[0094] 8 and 9, in one embodiment of the present application, the border shielding layer 60 includes a first portion 61 attached to the side of the counter substrate 12 away from the array substrate 11.

[0095] The support structure 30 includes a first portion 61 and a support 31 fixedly connected to the first portion 61 .

[0096] Since the support structure 30 is fixedly connected to the border shielding layer 60, the assembly process can be simplified, and the attachment of the support structure 30 and the border shielding layer 60 can be completed in a single attachment process, and the continuity of the border shielding layer 60 as a whole can be improved, making the attachment operation of the border shielding layer 60 more convenient. At the same time, the shielding area and attachment area of ​​the border shielding layer 60 can be improved, thereby improving the light-blocking effect and the strength of the attachment.

[0097] Alternatively, when the display device 100 is viewed from above, the support portion 31 has an elongated shape and is disposed so as to extend along the side of the first polarizer 21.

[0098] Alternatively, the support portion 31 may be installed so as to extend along the long side direction. Since the entire support portion 31 is installed on the ground side, the support for the front cover 41 is significantly improved, and friction between the front cover 41 and the first polarizer 21 is also significantly reduced. Furthermore, the long side of the support portion 31 may overlap the long side of the counter substrate 12, or may be located inside the long side of the counter substrate 12.

[0099] In one embodiment of the present application, the support 31 is fixedly connected to the first portion 61 of the border shielding layer 60 on the side away from the array substrate 11 .

[0100] By placing the support part 31 on the side facing the front cover 41, a material suitable for directly supporting the front cover 41 can be selected according to different functional requirements, such as the flexible material or the hard material in the above embodiment, while the vertical distance between the edge shielding layer 60 and the opposing substrate 12 can be reduced, thereby saving a certain amount of space.

[0101] The embodiment shown in Figures 10 and 11 is different from that shown in Figures 8 and 9. In Figures 10 and 11, only the parts that are different from the above-described embodiment will be described to avoid redundant explanation.

[0102] 10 and 11 , in one embodiment of the present application, a support portion 31 is fixedly connected to a first portion of the border shielding layer 60 on a side closer to the array substrate 11. The support structure 30 further includes an adhesive layer 32, which is connected between the support portion 31 and the counter substrate 12.

[0103] Here, by arranging the support portion 31 on the side of the border shielding layer 60 closer to the array substrate 11, the border shielding layer 60 covers the support portion 31, improving the visibility of the overall appearance.

[0104] In a display device according to an embodiment of the present application, the support structure is disposed on the side of the counter substrate away from the array substrate and is located on the side of the first polarizer closer to the edge of the counter substrate, and in a direction perpendicular to the plate surface of the display panel, a first distance is the distance from the surface of the support structure away from the array substrate to the surface of the counter substrate away from the array substrate, and a second distance is the distance from the surface of the first polarizer away from the array substrate to the surface of the counter substrate away from the array substrate, the first distance being equal to or greater than the second distance. That is, in the display device according to an embodiment of the present application, the front cover is supported by adding the support structure to the counter substrate, and even if the front cover comes off the first polarizer during relative movement, the front cover is supported by the support structure, thereby reducing rubbing of the front cover against the edge of the first polarizer.

[0105] The display device according to the embodiment of the present application has been described in detail above. However, the specific examples are applied to the specification to explain the principles and embodiments of the present application, and the description of the above embodiments is merely used to understand the method and concept of the present application. Furthermore, for those skilled in the art, there are changes in the specific embodiments and scope of application based on the concept of the present application. As such, the contents of the specification should not be construed as limiting the present application. [Explanation of symbols]
