[0045] [First embodiment]

[0046] Figure 1 It is a front view of the display device according to the first embodiment. Figure 2 yes Figure 1 Cross-sectional view along line II-II. Figure 3 yes Figure 1 Cross-sectional view along line III-III.

[0047] like Figure 1 As shown, the display panel 1 includes a light-transmitting portion 110 and a light-shielding portion 120 disposed outside the light-transmitting portion 110. The light-transmitting portion 110 is a display area of ​​the display device 100, and the light-shielding portion 120 is a frame area of ​​the display device 100.

[0048] like Figure 2 and Figure 3As shown, the display device 100 of the first embodiment includes a front panel 11, a display panel 1, a backlight 2, a light source 3, a container 41, a support member 42, and a clamping member 5. For example, the display device 100 modulates light emitted from the backlight 2 using the display panel 1 to display an image. Furthermore, in the first embodiment, the front panel 11, the display panel 1, and the backlight 2 have planar shapes. That is, the positions of the front panel 11, the display panel 1, and the backlight 2 in the Z direction remain constant as they are oriented in the X direction.

[0049] The outer edge of the front panel 11 is fixed to the support member 42 via the seal 20. The front panel 11 is a member for protecting the display device 100 and covers the display device 100. The front panel 11 is, for example, a glass substrate or a resin substrate.

[0050] like Figure 2 and Figure 3 As shown in FIG. 1 , a display panel 1 is provided on the back side of a front panel 11. The display panel 1 includes a first substrate 12, a second substrate 13, a liquid crystal layer 14, a first polarizing plate 15, and a second polarizing plate 16. The display panel 1 is a plate-like component, for example, having a rectangular shape in a plan view. Figure 2 As shown, at the end of the Y1 side of the display device 100, a long light source 3 extending along the X direction is provided. Figure 3 As shown, a driver IC 131 and a flexible printed circuit board 132 are provided at the end portion on the Y2 side of the display device 100 as will be described later.

[0051] like Figure 2 and Figure 3 As shown, on the rear side (Z2 side, rear side) of the front panel 11, a first polarizer 15, a first substrate 12, a liquid crystal layer 14, a second substrate 13, and a second polarizer 16 are stacked in this order. Specifically, the first polarizer 15 is arranged on the rear side (rear side) of the front panel 11. The first substrate 12 is arranged on the rear side (rear side) of the first polarizer 15. The liquid crystal layer 14 is arranged on the rear side (rear side) of the first substrate 12. The second substrate 13 is arranged on the rear side (rear side) of the liquid crystal layer 14. The second polarizer 16 is arranged on the rear side (rear side) of the second substrate 13.

[0052] In addition, if Figure 3 As shown, the second substrate 13 in the display panel 1 protrudes toward the Y1 side, and a driver IC 131 is mounted on the protruding portion. The driver IC 131 is electrically connected to a flexible printed circuit (FPC) 132 via electrodes not shown.

[0053] The third portion 52 of the clamping member 5 described later is provided with a through hole 522. The flexible printed circuit board 132 extends along the side surfaces of the third portion 52, the second portion 53, and the fourth portion 54 of the clamping member 5 after passing through the through hole 522.

[0054] Light emitted from the backlight 2 toward the front (Z1 side, front surface) passes through the second polarizer 16 and second substrate 13, enters the liquid crystal layer 14, and is modulated by the liquid crystal layer 14. The light modulated by the liquid crystal layer 14 then passes through the first substrate 12, first polarizer 15, and front panel 11, and is perceived as an image. The second polarizer 16 converts the light emitted from the backlight 2 into linearly polarized light. The first polarizer 15 transmits or blocks the light depending on the orientation (modulation) of the liquid crystal layer 14.

[0055] The backlight 2 is a plate-like member, for example, having a rectangular shape in a plan view, and includes, for example, a light guide plate 21 , a reflection sheet 22 , a first lens sheet 23 , a second lens sheet 24 , and a diffusion sheet 25 .

[0056] The backlight 2 is constructed by stacking a diffuser sheet 25, a second lens sheet 24, a first lens sheet 23, a light guide plate 21, and a reflector sheet 22 in this order. Specifically, the second lens sheet 24 is positioned behind (on the back side of) the diffuser sheet 25. The first lens sheet 23 is positioned behind (on the back side of) the second lens sheet 24. The light guide plate 21 is positioned behind (on the back side of) the first lens sheet 23. The reflector sheet 22 is positioned behind (on the back side of) the light guide plate 21.

[0057] The first lens sheet 23 and the second lens sheet 24 improve the directivity of light emitted from the surface of the light guide plate 21. The diffuser sheet 25 appropriately diffuses the light whose directivity is improved by the first lens sheet 23 and the second lens sheet 24. The reflector sheet 22 reflects the light leaking from the light guide plate 21 and makes it incident on the light guide plate 21. The reflector sheet 22 is, for example, foamed PET (polyethylene terephthalate). In addition, the reflector sheet 22 can also be a silver vapor-deposited film, a multi-layer reflective film, white PET, etc. The reflector sheet 22, the first lens sheet 23, the second lens sheet 24 and the diffuser sheet 25 are provided as needed and can also be omitted.

[0058] like Figure 2 As shown, light source 3 is arranged on the Y1 side of light guide plate 21. In other words, light source 3 is arranged opposite the side of light guide plate 21, and light is incident from the side of light guide plate 21. Light source 3 can be a plurality of light-emitting elements (such as light-emitting diodes) arranged at intervals along the X direction, or a single linear light-emitting element (such as a cold cathode tube) extending in the X direction.

[0059] In this embodiment, the light source 3 includes, for example, a plurality of light emitters 31 and a mounting substrate 32. In this embodiment, the light emitters 31 are light emitting diodes (LEDs). The plurality of light emitters 31 are mounted on the mounting substrate 32.

[0060] like Figure 2 and Figure 3 As shown, the housing 41 houses the backlight 2. The housing 41 is made of metal or resin. For example, a thin stainless steel plate can be used as the metal.

[0061] The housing 41 has a bottom 411 and a side 412. The bottom 411 is as shown in FIG. Figure 2 and Figure 3 The reflective sheet 22 is fixed to the bottom 411, for example, via double-sided tape. The side portion 412 extends from the end 413 of the bottom 411 toward the front (Z1 side, surface side). The light emitting body 31 is fixed to the side portion 412 via the mounting substrate 32.

[0062] The support member 42 has a leg portion 421 and a flange portion 422. The leg portion 421 extends in the front-back direction (Z direction, front-back direction). The leg portion 421 is located outside the side portion 412 of the housing 41. The flange portion 422 is as shown in FIG. Figure 2 and Figure 3 As shown, it extends along the front panel 11. A seal 20 is provided on the front surface of the flange portion 422, and the outer edge of the front panel 11 is provided on the front surface of the seal 20. In this way, the outer edge of the front panel 11 is supported by the flange portion 422 via the seal 20.

[0063] like Figure 2 and Figure 3 As shown, at least a portion of the outer edge of the front panel 11 and the outer edge of the flange 422 of the support member 42 is covered by the clamping members 5 and 5A. Figure 1 In the first embodiment, as shown in FIG. Figure 1 As shown, a clamping member 5 is provided at the end on the Y1 side, and a clamping member 5A is provided at the end on the Y2 side.

[0064] like Figure 2As shown, the clamping part 5 has a U-shaped cross section. The clamping part 5 is a long part extending in a straight line along the left-right direction (X direction). Specifically, the clamping part 5 has a first portion 51, a third portion 52, and a second portion 53. The first portion 51 is located on the surface side of the outer edge portion of the front panel 11. The second portion 53 is located on the back side of the flange portion 422. The third portion 52 connects the first portion 51 and the second portion 53. That is, the first portion 51 extends from the end 311 on the Y2 side to the end 512 on the Y1 side in a straight cross section. The third portion 52 extends from the end 512 on the Z1 side to the end 521 on the Z2 side in a straight cross section. The second portion 53 extends from the end 521 on the Y1 side to the end 531 on the Y2 side in a straight cross section. In addition, Figure 2 and Figure 3 In the embodiment, the first portion 51 contacts the front panel 11 but may be separated from the front panel 11. In addition, the second portion 53 contacts the flange portion 422 of the support member 42 but may be separated from the flange portion 422.

[0065] Briefly describe the order of assembling the clamping member 5 to the front panel 11 and the supporting member 42. For example, first, Figure 1 The X2-side end of the clamping member 5 is fitted into the X1-side end of the front plate 11 and the flange 422. Next, the clamping member 5 is slid toward the X2 side in the X direction to be attached to the front plate 11 and the support member 42.

[0066] like Figure 3 As shown, the clamping component 5A adds a fourth portion 54 and a fifth portion 55 to the clamping component 5. The clamping component 5A is an elongated component that extends linearly in the left-right direction (X direction). Specifically, the clamping component 5A includes a first portion 51, a third portion 52, a second portion 53, a fourth portion 54, and a fifth portion 55. The fourth portion 54 is connected to the second portion. The fourth portion 54 is located on the outside of the leg 421 of the support component 42. The fifth portion 55 is connected to the fourth portion 54. The fifth portion 55 is located on the back side of the leg 421. That is, the fourth portion 54 extends linearly from the end 531 toward the Z2 side to the end 541 in cross section. The fifth portion 55 extends linearly from the end 541 toward the Y2 side to the end 551 in cross section. The fifth portion 55 is located on the Z2 side of the leg 421 of the support component 42 and the bottom 411 of the container 41. Furthermore, as described above, the third portion 52 is provided with a through hole 522. The through hole 522 is formed, for example, from Figure 1 The X2-side end shown extends toward the X1 side in the X direction. The X1-side end of the through-hole 522 is, for example, the middle portion of the clamping member 5A in the X direction. That is, the X2-side end of the through-hole 522 is open. However, in this embodiment, the X1-side end of the through-hole 522 may also be open.

[0067] In the first embodiment, the clamping member 5 is provided at the end on the Y1 side, and the clamping member 5A is provided at the end on the Y2 side. However, this is not limiting, and various combinations of these can be employed. For example, the clamping member 5A can be provided at the end on the Y1 side, and the clamping member 5 can be provided at the end on the Y2 side. Furthermore, the clamping member 5 can be provided at both the end on the Y1 side and the end on the Y2 side, or the clamping member 5A can be provided at both the end on the Y1 side and the end on the Y2 side.

[0068] As described above, the display device 100 of the first embodiment includes a front panel 11, a display panel 1 arranged on the back side of the front panel 11, a backlight 2 arranged on the back side of the display panel 1, a housing 41 for accommodating the backlight 2, a supporting component 42 arranged on the back side of the front panel 11 and outside the housing 41 and supporting the front panel 11, and clamping components 5, 5A for clamping the outer edge of the front panel 11 and the outer edge of the supporting component 42.

[0069] As described above, in the display devices described in Patent Documents 1 and 2, the front panel is attached to the support member by bonding. In contrast, in the display device 100 of the first embodiment, the front panel 11 and the support member 42 are clamped by clamping members 5 and 5A. Therefore, in this embodiment, the front panel 11 and the support member 42 are more difficult to separate than in Patent Documents 1 and 2.

[0070] Since the outer edge of the support member 42 is the flange portion 422 extending along the front plate 11 , the front plate 11 and the support member 42 can be easily clamped via the clamping members 5 , 5A.

[0071] The clamping members 5, 5A include a first portion 51 located on the front side of the outer edge of the front panel 11, a second portion 53 located on the back side of the flange 422, and a third portion 52 connecting the first portion 51 and the second portion 53. Consequently, the structure of the clamping members 5, 5A is simplified, and the clamping members 5, 5A with such a simple structure can clamp the outer edge of the front panel 11 and the flange 422. Furthermore, the clamping members 5, 5A have multiple curved portions, resulting in increased rigidity.

[0072] The clamping member 5A includes a first portion 51 , a second portion 53 , a third portion 52 , a fourth portion 54 connected to the second portion 53 and located outside the leg 421 of the support member 42 , and a fifth portion 55 connected to the fourth portion 54 and located on the back side of the leg 421 .

[0073] Thus, the clamping member 5A further includes the fourth portion 54 and the fifth portion 55 relative to the clamping member 5. Therefore, compared with the clamping member 5, the front panel 11 and the support member 42 can be clamped more reliably, and the front panel 11 is less likely to be separated from the support member 42.

[0074] [First Modification]

[0075] Next, a first modification example will be described. Figure 4 1 is a cross-sectional view of a display device according to a first modification. A display device 100A according to the first modification further includes a first connection mechanism including a bolt 200 and a bolt hole 422 a , as compared to the display device 100 according to the first embodiment. This will be described in detail below.

[0076] like Figure 4 As shown, in the first modification, the clamping member 5 is provided at the Y1-side end of the display device 100A. The clamping member 5 includes a first portion 51 , a third portion 52 , and a second portion 53 . The second portion 53 is fixed to the flange portion 422 of the support member 42 via bolts 200 .

[0077] The second portion 53 is provided with a through-hole 53a. The bolt 200 can pass through the through-hole 53a. The flange portion 422 is provided with a bolt hole 422a. An internal thread is formed on the inner circumference of the bolt hole 422a. The external thread of the bolt 200 engages with this internal thread. Thus, by inserting the bolt 200 into the through-hole 53a of the second portion 53 and tightening it into the bolt hole 422a of the flange portion 422, the second portion 53 of the clamping member 5 is fixed to the flange portion 422 of the support member 42.

[0078] As described above, in the display device 100A of the first modified example, the second portion 53 of the clamping member 5 is connected to the flange portion 422 via the first connecting mechanism including the bolt 200 and the bolt hole 422a. Therefore, compared to the first embodiment, the front panel 11 and the support member 42 can be clamped more reliably, making it more difficult for the front panel 11 to separate from the support member 42.

[0079] [Second Modification]

[0080] Next, a second modification will be described. Figure 5 2 is a cross-sectional view of a display device according to a second modification. In the display device 100B according to the second modification, compared to the display device 100 according to the first embodiment, a second connection mechanism including a bolt 200 and a bolt hole 411a is further provided. This will be described in detail below.

[0081] In the second modification, a clamping member 5B is provided at the Y1-side end of the display device 100B. The clamping member 5B includes a first portion 51 , a third portion 52 , a second portion 53 , a fourth portion 54 , and a fifth portion 55 . The fifth portion 55 is fixed to the bottom 411 of the container 41 via bolts 200 .

[0082] The fifth portion 55 is provided with a through-hole 55a. The bolt 200 can pass through the through-hole 55a. The bottom 411 of the container 41 is provided with a bolt hole 411a. An internal thread is formed on the inner periphery of the bolt hole 411a. The external thread of the bolt 200 engages with this internal thread. Thus, by inserting the bolt 200 into the through-hole 55a of the fifth portion 55 and tightening it into the bolt hole 411a of the bottom 411, the fifth portion 55 of the clamping member 5 is fixed to the bottom 411 of the container 41.

[0083] As described above, in the display device 100B of the second modified example, the fifth portion 55 of the clamping member 5B is connected to the bottom 411 of the container 41 via the second connecting mechanism including the bolt 200 and the bolt hole 411a. Therefore, compared with the first embodiment, the front panel 11 and the support member 42 can be clamped more reliably, making it more difficult for the front panel 11 to separate from the support member 42.

[0084] [Third Modification]

[0085] Next, a third modification will be described. Figure 6 It is a cross-sectional view of a display device according to a third modified example. Figure 7 It is a perspective view of a clamping member according to a third modified example. Figure 8 This is a three-dimensional view of the second container of the third modified example. Figure 9 yes Figure 7 A display device 100C according to the third modification further includes a first connection mechanism including a first claw 530 and a first through-hole 423 , as compared to the display device 100 according to the first embodiment. Detailed description will be given below.

[0086] The clamping member 5C is provided at the end portion on the Y1 side of the display device 100C. Figure 7 As shown, the clamping member 5C of the third modification includes a first portion 51 , a third portion 52 , and a second portion 53 , and the second portion 53 is connected to the flange portion 422 of the support member 42 .

[0087] like Figure 6 、 Figure 7 and Figure 9 As shown, the first claw 530 is provided at the second portion 53, and an opening 532 is provided on the Z2 side of the first claw 530. The first claw 530 has a rectangular shape when viewed from the Z direction. Figure 9As shown, the first claw 530 includes a claw body 533 and a curved portion 534. The claw body 533 extends from end 535 toward the X1 side to end 536. Specifically, the claw body 533 tilts closer to the Z1 side from end 535 as it approaches the X1 side. The curved portion 534 extends from end 536 toward the Z2 side. The first claw 530 swings in the Z direction with end 535 as the base point. A rectangular opening 532 is provided in the second portion 53. The opening 532 is larger than the first claw 530, so that it does not hinder the swinging of the first claw 530.

[0088] like Figure 8 and Figure 9 As shown, the flange portion 422 of the support member 42 is provided with a first through hole 423. The shape and size of the first through hole 423 are substantially the same as those of the opening 532. Figure 9 As shown, when the first claw 530 swings, a portion of the first claw 530 can be accommodated inside the first through hole 423. In this way, a portion of the first claw 530 enters the inside of the first through hole 423, and the second portion 53 is connected to the flange portion 422 of the support member 42.

[0089] As described above, in the display device 100C of the third modified example, the second portion 53 of the clamping member 5C is connected to the flange portion 422 via the first connecting mechanism including the first claw 530 and the first through hole 423. Therefore, compared with the first embodiment, the front panel 11 and the support member 42 can be clamped more reliably, so that the front panel 11 is less likely to be separated from the support member 42. In particular, in the third modified example, due to the use of Figure 9 The first claw 530 of the shape shown in FIG. Figure 9 The first claw 530 slides toward the X2 side, elastically deforming and swinging in the Z direction with end 535 as the starting point. Specifically, while end 536 of the first claw 530 abuts the flange 422, the first claw 530 is pressed toward the Z2 side with end 535 as the starting point. When the first claw 530 enters the first through-hole 423, the first claw 530 elastically deforms and moves toward the Z1 side with end 535 as the starting point. Furthermore, by sliding the clamping member 5C further toward the X2 side, the clamping member 5C can be easily removed from the display device 100C.

[0090] [Fourth Modification]

[0091] Next, a fourth modification will be described. Figure 10 It is a cross-sectional view of a display device according to a fourth modified example. Figure 11 It is a perspective view of a clamping member according to a fourth modified example. Figure 12 It is a three-dimensional view of the second container of the fourth variant. Figure 13 yes Figure 11Cross-sectional view along line XIII-XIII.

[0092] The clamping member 5D is provided at the Y1-side end of the display device 100D. The display device 100D of the fourth modification further includes a second connection mechanism including a second claw 540 and a second through hole 424, as compared to the display device 100 of the first embodiment. This will be described in detail below.

[0093] like Figure 11 As shown, the clamping member 5D of the fourth modification includes a first portion 51 , a third portion 52 , a second portion 53 , a fourth portion 54 , and a fifth portion 55 . The fourth portion 54 is fixed to the leg portion 421 of the support member 42 via a snap-fit ​​structure.

[0094] like Figure 11 and Figure 13 As shown, the 4th part 54 is provided with a second claw 540, and an opening 542 is provided on the Y1 side of the second claw 540. The second claw 540 has a rectangular shape when viewed from the Y direction. Figure 13 As shown, the second claw 540 includes a claw body 543 and a curved portion 544. The claw body 543 extends from end 545 toward the X1 side to end 546. Specifically, the claw body 543 tilts closer toward the Y2 side from end 545 as it approaches the X1 side. The curved portion 544 extends from end 546 toward the Y1 side. The second claw 540 swings in the Y direction with end 545 as the base point. A rectangular opening 542 is provided in the fourth portion 54. The opening 542 is larger than the second claw 540, so that it does not hinder the swinging of the second claw 540.

[0095] like Figure 12 and Figure 13 As shown, the leg portion 421 of the support member 42 is provided with a second through hole 424. The shape and size of the second through hole 424 are substantially the same as those of the opening 542. Figure 13 As shown, when the second claw 540 swings, a portion of the second claw 540 can be accommodated inside the second through hole 424. In this way, a portion of the second claw 540 enters the inside of the second through hole 424, thereby connecting the fourth portion 54 to the leg 421 of the support member 42.

[0096] As described above, in the display device 100D of the fourth modified example, the fourth portion 54 of the clamping member 5D is connected to the leg 421 via the second connection mechanism including the second claw 540 and the second through hole 424. Therefore, compared with the first embodiment, the front panel 11 and the support member 42 can be clamped more reliably, so that the front panel 11 is less likely to be separated from the support member 42. In particular, in the fourth modified example, Figure 13The second claw 540 of the shape shown in FIG. Figure 13 The second claw 540 slides toward the X2 side, elastically deforming and swinging in the Y direction with end 545 as the starting point. Specifically, while end 546 of the second claw 540 abuts the leg 421, the second claw 540 is pressed toward the Y1 side with end 545 as the starting point. When the second claw 540 enters the second through-hole 424, the second claw 540 elastically deforms and moves toward the Y2 side with end 545 as the starting point. Furthermore, by sliding the clamping member 5D further toward the X2 side, the clamping member 5D can be easily removed from the display device 100D.

[0097] [Second embodiment]

[0098] Next, a display device according to a second embodiment will be described. Figure 14 It is a front view of the display device according to the second embodiment. Figure 15 yes Figure 14 Cross-sectional view of line XV-XV. Figure 16 yes Figure 14 Cross-sectional view along line XVI-XVI.

[0099] The display device 100E of the second embodiment is Figure 1 The difference of the display device 100 of the first embodiment shown is that the clamping member on the Y1 side is the clamping member 5E. That is, in the second embodiment, the clamping member 5E is provided at the end on the Y1 side, and the clamping member 5A is provided at the end on the Y2 side. The details are described below. In addition, in the second embodiment, the display panel 1 and the backlight 2 have a planar shape in the same manner as in the first embodiment. In addition, the cross-section of the end on the Y2 side is the same as that of the first embodiment. Figure 3 Since they are the same, the description is omitted.

[0100] The clamping member 5E has the same cross-sectional shape as the clamping member 5, but is shorter in the X direction than the clamping member 5. The clamping member 5E is a long member extending in a straight line in the left-right direction (X direction). Figure 15 As shown, the clamping part 5E has a U-shaped cross section. The clamping part 5 is a long-sized part that extends longer in the left-right direction (X direction). Specifically, the clamping part 5 has a first portion 51, a third portion 52, and a second portion 53. The first portion 51 extends from the end 311 on the Y2 side to the Y1 side in a straight cross section to the end 512. The third portion 52 extends from the end 512 on the Z1 side to the Z2 side in a straight cross section to the end 521. The second portion 53 extends from the end 521 on the Y1 side to the Y2 side in a straight cross section to the end 531. In addition, Figure 15In the embodiment, the first portion 51 contacts the front panel 11 but may be separated from the front panel 11. In addition, the second portion 53 contacts the flange portion 422 of the support member 42 but may be separated from the flange portion 422.

[0101] In addition, the portion other than the clamping member 5E at the end portion on the Y1 side of the display device 100E has Figure 16 The cross-sectional structure shown.

[0102] As described above, the display device 100E of the second embodiment, similar to the first embodiment, clamps the front panel 11 and the support member 42 via the clamping member 5 having the first portion 51, the third portion 52, and the second portion 53. Therefore, the front panel 11 is more difficult to separate from the support member 42. In particular, in the second embodiment, the clamping member 5E has a shorter length in the X direction than the clamping member 5, resulting in a lighter weight and lower component costs.

[0103] [Third embodiment]

[0104] Next, a display device according to a third embodiment will be described. Figure 17 It is a front view of a display device according to a third embodiment.

[0105] The display device 100F of the third embodiment is Figure 1 The display device 100 of the first embodiment shown is different in that it does not include a Y1-side holding member. In the third embodiment, the display panel 1 and the backlight 2 have a planar shape similarly to the first and second embodiments.

[0106] That is, in the display device 100F of the third embodiment, as Figure 17 As shown, there is no clamping member at the end on the Y1 side, and a clamping member 5A is provided at the end on the Y2 side. Figure 3 As described in [ 1 ], the clamping member 5A includes a first portion 51, a third portion 52, a second portion 53, a fourth portion 54, and a fifth portion 55. The fourth portion 54 extends from end 531 toward the Z2 side in a straight cross-sectional shape to end 541. The fifth portion 55 extends from end 541 toward the Y2 side in a straight cross-sectional shape to end 551. The fifth portion 55 is located on the Z2 side of the leg portion 421 of the support member 42 and the bottom portion 411 of the container 41.

[0107] As described above, the display device 100F of the third embodiment does not include a holding member on the Y1 side, and therefore has a smaller weight and lower component costs than other embodiments.

[0108] [Fourth embodiment]

[0109] Next, a display device according to a fourth embodiment will be described. Figure 18 It is a front view of a display device according to a fourth embodiment. Figure 19 yes Figure 18 Bottom view of . Figure 20 yes Figure 18 Cross-sectional view of line XX-XX. Figure 21 yes Figure 18 Cross-sectional view of line XXI-XXI.

[0110] In the display device 100G of the fourth embodiment, the front panel 11, the display panel 1, and the backlight 2 are different from those in the first embodiment and have curved shapes. Figure 19 As shown in FIG, the clamping member 5F also has a curved surface shape that curves toward the X direction.

[0111] Figure 20 and Figure 21 The display panel 1A and backlight 2A shown have a curved surface shape that curves toward the X direction. Specifically, the center portion of the display panel 1A and backlight 2A in the X direction is located on the Z2 side and is recessed toward the back side (rear side). As the center portion in the X direction is moved toward the left and right sides (X1 side and X2 side), the display panel 1A and backlight 2A curve toward the front side (front side).

[0112] In addition, if Figure 18 As shown in FIG. 1 , a clamping member 5F is provided at the end of the Y1 side and the end of the Y2 side of the display device 100G. The clamping member 5F has a curved surface shape that curves toward the X direction as described above. Specifically, Figure 19 As shown, the center portion of the holding member 5F in the X direction is recessed toward the back side, and is curved toward the front side as it moves from the center portion in the X direction toward the left and right sides (X1 side, X2 side).

[0113] As described above, the display device 100G of the fourth embodiment clamps the front panel 11 and the support member 42 via the clamping member 5F, which, like the clamping member 5A of the first embodiment, has the first portion 51, the third portion 52, the second portion 53, the fourth portion 54, and the fifth portion 55. Therefore, even if the display panel 1A, the backlight 2A, and the clamping member 5F are bent, the front panel 11 is less likely to separate from the support member 42.

[0114] While the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. The contents disclosed in the embodiments are merely examples, and various modifications can be made without departing from the scope of the present invention. Suitable modifications made without departing from the scope of the present invention naturally also fall within the technical scope of the present invention.
