Abstract
Description
Technical Field
[0001] This application relates to the field of display technologies, and more specifically, to a display device.
Background Art
[0002] With the narrowing of the bezel of handheld computer products, the requirements for the consistency between the module and the entire chassis are becoming increasingly high. Due to factors such as the design tolerance and assembly tolerance of the product, the mismatch between the module and the chassis of the narrow-bezel product frequently occurs, and among them, the problem of abnormal noise is particularly prominent.
[0003] In the process of researching and implementing the prior art, the inventor of this application discovered that the cause of the abnormal noise due to the interference between the module and the chassis is that there is a step between the polarizer attached to the color film substrate and the cell tape attached to the color film substrate. Due to assembly tolerance and narrow bezels, the overlapping width between the polarizer and the chassis is insufficient, and when the entire machine opens, closes, or shakes, the edges of the polarizer and the chassis rub against each other, generating abnormal noise.

Mode for Carrying Out the Invention
[0026] Hereinafter, the invention according to the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings. However, it is obvious that the described embodiments are only a part of the embodiments of the present application and not all of the embodiments. Based on the embodiments of the present application, all other embodiments that can be obtained by those skilled in the art without creative labor belong to the protection scope of the present application. Furthermore, it should be understood that the specific embodiments described in this specification are only for exemplifying and explaining the present application and are not intended to limit the present application. In the present application, unless otherwise stated, directional terms such as "upper" and "lower" used usually refer to the upper and lower parts in the actual use state or working state of the device, specifically, the direction of the drawings in the accompanying drawings. On the other hand, directional terms such as "inner" and "outer" are about the contour of the device. Terms such as "first", "second", "third", etc. are used only as identifiers and do not impose numerical requirements or define an order.
[0027] In the related art, as shown in FIG. 1, a narrow bezel display device, such as a handheld computer, includes a backlight module F1, a display module F2, a bezel 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 installed on the color film substrate F22, the lower polarizer F24 is installed on the side of the array substrate F21 away from the color film substrate F22, the bezel 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. Here, there is a step between the upper polarizer F23 and the bezel shielding tape F3.
[0028] Due to the requirements of the narrow bezel and the assembly tolerance between the first polarizer and the chassis, the overlapping width between the front case F5 and the upper polarizer F23 is insufficient. When the chassis opens and closes, the edges of the upper polarizer F23 and the front case F5 rub against each other, generating abnormal noises.
[0029] Here, since an electronic circuit such as a flexible circuit board is provided on the ground side of the module, when the module and the chassis perform the opening and closing operation, referring to FIGS. 2 and 3, the ground side of the module is affected by the flexible circuit board and the like, and the upper polarizer F23 and the front case F5 of the chassis are prone to relative movement, while the other side (ceiling side and left and right sides) is less prone to relative movement. Therefore, it should be understood that abnormal noises often occur on the ground side of the module.
[0030] Also, 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 between the module and the bottom case F4 is ±0.5 mm.

Number
[0031] In order to solve the above problems, the display device according to the embodiment of the present application supports the front cover by adding a support structure on the counter substrate. When the front cover moves relatively, even if the front cover comes off from the first polarizer, the front cover is supported by the support structure, so that the rubbing of the front cover against the edge portion of the first polarizer is reduced.
[0032] The embodiment of the present application provides a display device, which will be described in detail below. Note that the order of the following description of the embodiments is not limited to the preferred ones of the embodiments.
[0033] Referring to FIGS. 4 and 5, FIGS. 4 and 5 show a display device 100 according to an embodiment of the present application. The case where the display device 100 is applied to a notebook computer will be described, but the embodiment is not limited thereto. For example, in addition to a notebook computer, the display device 100 can also be applied to a mobile phone, a tablet personal computer (PC), a personal digital assistant (PDA), a portable multimedia player (PMP), a television, a game machine, a wristwatch-type electronic device, a head-mounted display, a display for a personal computer, a smartphone, a vehicle navigation system, a vehicle dashboard, a digital camera, a video camera, an outdoor signboard, an electronic display panel, a medical device, an inspection device, various household appliances such as a refrigerator and a washing machine, or an Internet of Things device. Hereinafter, a detailed embodiment will be described with reference to the drawings.
[0034] The display device 100 may have a rectangular shape in a plan view from above, but the embodiments are not limited thereto. For example, the display device 100 may have a rectangular shape or other shape with vertical corners or chamfered corners in a plan view from above. Further, the display device 100 may be included in 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 installed to face the array substrate 11. The first polarizer 21 is installed on the side of the counter substrate 12 away from the array substrate 11. The support structure 30 is installed on the side of the counter substrate 12 away from the array substrate 11 and is located on the side close to the edge of the counter substrate 12 of the first polarizer 21. The front cover 41 is installed on the side of the support structure 30 and the first polarizer 21 away from the array substrate 11, and the front cover 41 covers the edge region of the first polarizer 21 and the support structure 30.
[0037] In the 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 the 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 the second distance d2. The first distance d1 is equal to or greater than the second distance d2.
[0038] Here, the direction perpendicular to the plate surface of the display panel 10 is the thickness direction of the display panel 10.
[0039] In the display device 100 according to the embodiment of the present application, a support structure 30 is added to the counter substrate, where the first distance d1 is greater than or equal to the second distance d2, that is, the support structure 30 is higher than the first polarizer 21 or flush with the first polarizer 21. Thereby, the front cover 41 is supported, and when the front cover 41 and the first polarizer 21 move relative to each other, even if the front cover 41 deviates from the first polarizer 21, the front cover 41 is supported by the support structure 30. As a result, the rubbing of the front cover 41 against the edge portion of the first polarizer 21 is reduced.
[0040] It should be understood that the higher the support structure 30 is, that is, the larger the first distance d1 is, the farther the front cover 41 is from the first polarizer 21 in the thickness direction of the display panel 10, so that the relative movement and rubbing of the front cover 41 against the first polarizer 21 are reduced.
[0041] Optionally, the first distance d1 is at most 0.05 mm greater than the second distance d2. 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 width of the gap between the first polarizer 21 and the front cover 41 and improve the overall flatness and sealing effect of the display device 100. Among them, 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 the best.
[0043] In some embodiments, in order to improve the protection performance of the first polarizer 21, the protective 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 on 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 is flush with the protective layer or may be slightly higher than the protective layer.
[0045] Optionally, the protective layer may be a cover plate or a cured layer.
[0046] Also, the support structure 30 is fixed to the side of the counter substrate 12, and the support structure 30 can be flexibly set according to counter substrates 12 with different sizes and shapes. Thus, it should be understood that compared with the case of fixing the support structure 30 to the front cover 41, it provides greater adaptability and reduces the possibility of interference in the assembly of the support structure 30.
[0047] Optionally, the support structure 30 has a support length L1 in the short side direction, and the support length L1 is greater than 0.06 mm. Further, the support length L1 is 0.66 mm or more.
[0048] When the designed overlapping width between the front cover 41 and the first polarizer 21 is 0.6 mm, due to the requirements of assembly tolerance, it should be understood that if the support length L1 is greater than 0.06 mm, the tolerance of 0.66 mm can be overcome. Based on this, the support length L1 of the support structure 30 can be appropriately adjusted according to the designed overlapping width between the front cover 41 and the first polarizer 21.
[0049] In an embodiment of the present application, covering the edge region of the front cover 41 and the first polarizer 21 means that the front cover 41 can cover at least one side edge region of the first polarizer 21. For example, it can cover the edge regions on the four sides around the first polarizer 21, can cover the edge regions on three adjacent sides, can cover the edge regions on two adjacent sides, and of course, can also cover the edge region on one side. Here, the present application takes the case where the front cover 41 covers the edge regions on the four sides around the first polarizer 21 as an example.
[0050] In one embodiment of the present application, the front cover 41 includes a cover main body 41a and a reinforcing rib 41b. The cover main body 41a wraps the reinforcing rib 41b, and the hardness of the reinforcing rib 41b is greater than that of the cover main body 41a.
[0051] Here, in order to increase the rigidity of the front cover 41, a reinforcing rib 41b with high hardness is installed in the cover main body of the front cover 41. When the front cover 41 and the first polarizer 21 move relative to each other due to the opening and closing operation, the front cover 41 with good rigidity is less likely to generate sagging distortion, and it can reduce the rubbing between the front cover 41 and the first polarizer 21 up and down.
[0052] Optionally, 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 simply be formed of plastic or a metal alloy, or may be formed of other materials.
[0054] For example, in some embodiments, the front cover 41 may be formed of a mixed material composed of mixed hard particles containing a resin material. Since the front cover 41 of the mixed hard particles has strong rigidity, it is possible to reduce the rubbing of the front cover 41 and the first polarizer 21 against each other vertically, and to enhance the abrasion resistance of the front cover 41. Also, by adding hard particles, the outer surface of the front cover 41 becomes a polished surface, and the effect on specular reflection can be reduced. Optionally, the hard particles may be ceramic particles, quartz particles, or other materials.
[0055] The display panel 10 is a liquid crystal display panel. The liquid crystal is installed between the array substrate 11 and the counter substrate 12. The counter substrate 12 is a color filter substrate, that is, a color filter layer is fixedly connected to the counter substrate 12. In some embodiments, the color filter 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 installed opposite to the counter substrate 12. The bonding region BD is located outside the counter 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 is installed on the side of the array substrate 11 away from the counter substrate 12. The backlight module 50 is installed on the side of the second polarizer 22 away from the display panel 10.
[0058] The backlight module 50 provides a backlight source to the display panel 10. The backlight module 50 may be a direct - type backlight or an edge - lit backlight.
[0059] The display device 100 further includes a border shielding layer 60, and the border shielding layer 60 is installed on the outer periphery of the first polarizer 21. One side portion of the border shielding layer 60 covers the side away from the array substrate 11 of the counter substrate 12, and the other side portion of the border shielding layer 60 is bent along the side surface of the backlight module 50 to the back surface of the backlight module 50.
[0060] Optionally, the border shielding layer 60 may be a black tape, a light-shielding tape with electromagnetic shielding, or other members having a light-shielding effect.
[0061] Optionally, the first polarizer 21 is installed in the middle region of the counter substrate 12 so that the edge portions on the four sides around the counter substrate 12 are exposed. On the other hand, a part of the border shielding layer 60 is covered and attached to the edge portions on the four sides around 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. In this case, the border shielding layer 60 is attached to the side surface of the counter substrate 12 or the exposed area of the array substrate 11. That is, the border shielding layer 60 is not installed on the light-emitting surface of the counter substrate 12.
[0062] The display device 100 further includes a bottom case 42, and a receiving groove 40a is installed in the bottom case 42. The backlight module 50, the display panel 10, and the border shielding layer 60 are installed in the receiving groove 40a, and 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 an embodiment of the present application, the support structure 30 is located at least on the side close to the bonding region BD of the array substrate 11 of the first polarizer 21.
[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 ground side region, the rubbing between the front cover 41 and the first polarizer 21 can be minimized, and the risk of generating abnormal noise can be reduced.
[0065] It should be understood that by installing the support structure 30 in an area where rubbing is likely to occur, the possibility of generating abnormal noise can be minimized. Therefore, in order to comprehensively reduce the possibility of generating abnormal noise, the support structure 30 may be installed on the four side edges around the counter substrate 12. Also, the larger the occupied area of the support structure 30, the lower the possibility of generating 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, that is, 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, the assembly tolerance of the support structure 30 itself and its assembly to other components is avoided, that is, since the support portion 31 and the first polarizer 21 are integrally assembled, the assembly convenience is improved.
[0068] Optionally, the support portion 31 is integrally formed of the same material as the first polarizer 21. That is, the support portion 31 and the first polarizer 21 are an integral structure formed by cutting the same polarizer blank. Therefore, the difficulty of module assembly is simplified, the assembly tolerance between the support structure 30 and the first polarizer 21 is avoided, and the achievement of the flush height between the support structure 30 and the first polarizer 21 is facilitated.
[0069] Optionally, in some embodiments, the material of the support portion 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 an optical adhesive layer. When the optical adhesive is fixedly connected to the first polarizer 21, the support structure 30 becomes an extended portion of the first polarizer 21. When the first polarizer 21 is attached to the counter substrate 12 by an additional optical adhesive, the support structure 30 further includes 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, when 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 area on the ground side. When the size of the display panel 10 is large, a plurality of support structures 30 can be installed, and the support structures 30 are installed in the middle area on the ground side and the edge areas on both sides. Hereinafter, an example in which three support structures 30 shown in FIG. 4 are installed on the ground side will be used for description.
[0072] In an embodiment of the present application, in a top view of the display device 100, the boundary of the support structure 30 on the side close to the counter substrate 12 is spaced from the boundary of the counter substrate 12 by a blank space 3a.
[0073] An avoidance opening 6a is provided on the side of the edge shielding layer 60 close to the first polarizer 21, and the support structure 30 is installed in the avoidance opening 6a. In a top view of the display device 100, the edge shielding layer 60 is continuously attached to the counter substrate 12 by the blank space 3a in the side edge region of the counter substrate 12 corresponding to the support structure 30.
[0074] Since the support structure 30 does not cover the entire counter substrate 12 in the extending direction of the short side of the display panel 10, an empty space 3a is formed in the uncovered area of the counter substrate 12, and the corresponding avoidance opening 6a does not cut the portion of the edge shielding layer 60 located on the upper surface of the counter substrate. The formation of the empty space 3a improves the pasting area of the edge shielding layer 60, enhances the stability of pasting and the overall coverage, and thus improves the light-shielding effect. Next, in order to make the edge shielding layer 60 continuous corresponding to the entire upper surface of the counter substrate 12, it should be understood that the overall pasting is facilitated and the pasting efficiency is improved.
[0075] Optionally, in some embodiments of the present application, in the top view of the display device 100, the boundary of the support structure 30 closer to the counter substrate 12 overlaps with the boundary of the counter substrate 12.
[0076] Since the boundaries of the support structure 30 and the counter substrate 12 overlap, the size of the support structure 30 on the plane increases, the support area of the support structure 30 for the front cover 41 is improved, and the possibility of generating abnormal noise is reduced.
[0077] Optionally, the support structures 30 are provided at equal distances in the ground side region of the display device 100. The width of the support structure 30 is 10 mm to 20 mm in the length direction of the display panel 10, and for example, it may be 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 size of the support structure 30 on the plane can be appropriately adjusted according to the requirements of pasting the edge shielding layer 60 and the support for the front cover 41, and the embodiments of the present application are not strictly limited.
[0079] The embodiments shown in FIGS. 6 and 7 are different from those shown in FIGS. 4 and 5. In FIGS. 6 and 7, in order to avoid repeated descriptions, the parts different from the above-described embodiments will be described.
[0080] Referring to FIGS. 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 counter substrate 12 side in independent steps respectively. Here, since the support structure 30 and the first polarizer 21 are installed independently of each other, it is advantageous that the support structure 30 can select a wider range of materials and structures, which endows it with better 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] By setting the distance between the support structure 30 and the first polarizer 21 to 0.15 mm or less, it can be well ensured that the front cover 41 and the first polarizer 21 do not rub against each other due to vertical displacement. Here, the smaller the distance between the support structure 30 and the first polarizer 21, the better the effect of preventing rubbing.
[0084] Optionally, 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 counter 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 is a welding layer, and the support structure 30 may be fixed to the counter substrate 12 side by welding.
[0087] Further, the support structure 30 can be a positioning structure for the attachment operation of the first polarizer 21. That is, with the support structure 30 as a reference object, since the first polarizer 21 can contact the support structure 30 and perform the attachment operation, assembly tolerances can be reduced.
[0088] Optionally, the material of the support portion 31 is a flexible material. Since the support portion 31 is a flexible material such as PET, rubber, or foamed sponge, for example, it has good cushioning properties and can absorb external stress. Next, when the support portion 31 is slightly higher than the first polarizer 21 (the difference between the first distance d1 and the second distance d2 is 0.05 mm or less), the front cover 41 slightly presses the support portion 31 downward, and the support portion 31 undergoes minute deformation, thereby improving the sealing effect. At the same time, due to the downward pressing of the front cover 41, the adhesive layer 32 is firmly adhered to the support portion 31 and the counter substrate 12 respectively, and the strength of the adhesion can be improved.
[0089] Optionally, the elastic modulus of the support portion 31 is 10 MPa to 4000 MPa so that the support portion 31 has cushioning properties and good supportability at the same time. For example, the elastic modulus of the support portion 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 ceramics or an alloy. The support portion 31 uses a support material to enhance supportability and wear resistance.
[0091] Optionally, the elastic modulus of the support portion 31 is higher than that of the first polarizer 21. That is, the hardness of the support structure 30 is greater than that of the first polarizer 21, and the support structure 30 has good supportability so as to reduce the possibility of downward pressing of the front cover 41.
[0092] Optionally, the elastic modulus of the support portion 31 is 70 GPa or more. For example, it may be 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 embodiments shown in FIGS. 8 and 9 are different from those shown in FIGS. 6 and 7. In FIGS. 8 and 9, in order to avoid redundant explanations, the parts different from the above-described embodiments will be described.
[0094] Referring to FIGS. 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 array substrate 11 of the counter substrate 12 away from the array substrate 11.
[0095] The support structure 30 includes the first portion 61 and a support portion 31 fixedly connected to the first portion 61.
[0096] By fixedly connecting the support structure 30 to the border shielding layer 60, the assembly process can be simplified, the attachment of the support structure 30 and the border shielding layer 60 can be completed in a single attachment process, and moreover, the continuity of the entire border shielding layer 60 can be improved, the attachment operation of the border shielding layer 60 can be made more convenient, and at the same time, the shielding area and the attachment area of the border shielding layer 60 can be improved, thereby improving the light shielding effect and the strength of the attachment.
[0097] Optionally, in a top view of the display device 100, the support portion 31 is elongated and extends along the side direction of the first polarizer 21 and is installed.
[0098] Optionally, the support portion 31 extends along the long side direction and is installed. Since the entire support portion 31 is installed on the ground side, the supportability for the front cover 41 is greatly improved, and the rubbing between the front cover 41 and the first polarizer 21 is also greatly reduced. Further, the long side of the support portion 31 may overlap with the long side of the counter substrate 12 or may be disposed inside the long side of the counter substrate 12.
[0099] In one embodiment of the present application, the support portion 31 is fixedly connected to the side of the first portion 61 of the edge shielding layer 60 away from the array substrate 11.
[0100] By installing the support portion 31 on the side facing the front cover 41, it is possible to select a material suitable for directly supporting the front cover 41 according to different functional requirements, for example, the flexible material or the hard material of the above embodiment, while the vertical distance between the edge shielding layer 60 and the counter substrate 12 can be reduced, and a certain amount of space can be saved.
[0101] The embodiments shown in FIGS. 10 and 11 are different from those shown in FIGS. 8 and 9. In FIGS. 10 and 11, in order to avoid redundant explanations, the parts different from the above-described embodiments will be described.
[0102] Referring to FIGS. 10 and 11, in one embodiment of the present application, the support portion 31 is fixedly connected to the side of the first portion of the edge shielding layer 60 close to the array substrate 11. The support structure 30 further includes an adhesive layer 32, and the adhesive layer 32 is connected between the support portion 31 and the counter substrate 12.
[0103] Here, by installing the support portion 31 on the side of the edge shielding layer 60 close to the array substrate 11, the edge shielding layer 60 covers the support portion 31 and the visibility of the entire appearance is improved.
[0104] In the display device according to the embodiment of the present application, the support structure is installed on the side of the counter substrate away from the array substrate, located on the side closer to the edge of the counter substrate of the first polarizer, and in the direction perpendicular to the plate surface of the display panel, 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 is the first distance, 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 is the second distance, and the first distance is equal to or greater than the second distance. That is, the display device according to the embodiment of the present application supports the front cover by adding a support structure to the counter substrate. When the front cover moves relatively, even if the front cover comes off from the first polarizer, the front cover is supported by the support structure. Therefore, the rubbing between the front cover and the edge portion of the first polarizer is reduced.
