Description

display device

The present disclosure relates to a display device.

Some display devices include a display section, a cover member, and a design panel. The display section has a display surface on its front surface. The cover member covers and protects the front surface of the display section from the front. The design panel surrounds and supports the display section. Further, the cover member and the design panel are fixed to each other via an adhesive member such as double-sided tape or adhesive.

In display devices, the display section and its peripheral parts may be repaired or replaced. In this case, it is necessary to peel off the adhesive member and remove the cover member from the design panel. On the other hand, Patent Document 1 discloses a display device in which the work of peeling a cover member from a design panel is simplified.

JP2015-138231A

The display device disclosed in Patent Document 1 includes a peeling means. This peeling means is provided so as to be able to be pulled along the longitudinal direction of the attached double-sided tape between the rear surface of the cover member and the front surface of the design panel. One end of the peeling means is arranged to protrude from a guide hole formed on the rear surface of the design panel. A peeling blade is formed at the other end of the peeling means.

When performing the peeling work, the operator pulls one end of the gripped peeling means toward the rear of the design panel. Therefore, the peeling means is pulled out from between the rear surface of the cover member and the front surface of the design panel. Along with this, the peeling blade of the peeling means is pulled out while acting on the adhesive surface of the double-sided tape with the cover member. As a result, the adhesive state between the cover member and the design panel is released.

As described above, the display device disclosed in Patent Document 1 releases the adhesive state between the cover member and the design panel by pulling the peeling means. However, in the display device disclosed in Patent Document 1, although the adhesive state is released, the double-sided tape still remains stuck to the design panel side. This double-sided tape cannot be reused because the adhesive surface is damaged by the peeling blade of the peeling means.

Therefore, when a worker completes the repair or replacement of parts of the display device and reassembles the cover member and design panel, after removing the double-sided tape that cannot be reused, apply a new double-sided tape. It is necessary to attach it. Moreover, correspondingly, it is also necessary to provide a peeling means along the double-sided tape. Therefore, the display device disclosed in Patent Document 1 has a problem in that the reassembly work between the cover member and the design panel becomes complicated.

The present disclosure has been made to solve the above-mentioned problems, and an object of the present disclosure is to provide a display device from which double-sided tape can be pulled out.

A display device according to the present disclosure includes a cover member that is bonded to each other with double-sided tape between a design panel that houses a display section, and an outer peripheral edge of the front surface of the design panel that covers the front surface of the display section and the front surface of the design panel. and a guide hole that opens in the design panel and allows the pasted double-sided tape to be pulled out toward the rear of the design panel. A separator is attached to protect the adhesive surface of the tape.

According to the present disclosure, the double-sided tape can be pulled out. As a result, the present disclosure can improve the ease of reassembling between the cover member and the design panel.

FIG. 6 is a diagram showing the configuration of the clip 50 corresponding to section A in FIG. 2. As shown in FIG. FIG. 7 is a diagram showing the configuration of the clip 60 corresponding to section B in FIG. 2. As shown in FIG. FIG. 8 is a diagram showing the configuration of the clip 70 corresponding to section C in FIG. 2. As shown in FIG. FIG. 9 is a diagram showing the configuration of the clip 80 corresponding to section D in FIG. 2. As shown in FIG. FIG. 10 is a diagram showing how the cover member 20 warps when the display device 100 is maintained at a high temperature.

The display device 100 shown in FIG. 1 is, for example, an in-vehicle device mounted in a vehicle compartment (not shown). This display device 100 is provided so as to face inside the vehicle interior, and displays various information regarding the vehicle. Note that in the display device 100, the side where information is viewed, that is, the side where information is displayed is the front side. The display device 100 is formed into a rectangular shape when viewed from the front (from inside the vehicle interior). The display device 100 is arranged with the long side direction being the horizontal direction (width direction) and the short side direction being the vertical direction.

As shown in FIG. 1, the display device 100 includes a display section 10, a cover member 20, a design panel 30, a double-sided tape 40, clips 50, 60, 70, 80, and the like. Although details will be described later, the cover member 20 and the design panel 30 are fixed to each other with double-sided tape 40 and clips 50, 60, 70, and 80.

The display section 10 is formed into a horizontally long rectangular shape when viewed from the front. The display section 10 has a display surface 11 . The display surface 11 forms the front surface of the display section 10, and is capable of displaying the above-mentioned various information. Note that the display unit 10 is, for example, a touch-type liquid crystal panel. In this case, the display surface 11 allows touch operations via a cover member 20, which will be described later.

The cover member 20 is formed into a horizontally long rectangular shape when viewed from the front. This cover member 20 protects the display surface 11 of the display section 10. The cover member 20 is made of transparent glass or resin, for example. The cover member 20 is larger than the display surface 11 and is arranged to cover the display surface 11 from the front side. The rear surface of the cover member 20 and the display surface 11, which is the front surface of the display section 10, are bonded to each other with an adhesive.

The design panel 30 is formed into a horizontally long rectangular shape when viewed from the front. This design panel 30 is made of resin or metal, for example. The display device 100 is installed inside a vehicle interior, for example, via a design panel 30.

Here, the cover member 20 and the design panel 30 are adhered to each other by sandwiching the double-sided tape 40. Specifically, the vertical sides of the outer periphery on the rear surface of the cover member 20 and the vertical sides of the outer periphery on the front surface of the design panel 30 are adhered to each other with a short double-sided tape 40. Further, the lateral side of the outer periphery on the rear surface of the cover member 20 and the lateral side of the outer periphery on the front surface of the design panel 30 are adhered to each other with a long double-sided tape 40. The double-sided tape 40 is attached so as to surround the periphery of the display section 10.

Note that the outer peripheral edge of the rear surface of the cover member 20 is an area that does not come into contact with the display surface 11. For example, black printing is applied to the outer peripheral edge. Therefore, the outer periphery serves as a light-shielding area. As a result, the double-sided tape 40 is not visible from the front side even when the user looks at the display surface 11. Further, the cover member 20 and the design panel 30 are fixed to each other using screws or the like in addition to the double-sided tape 40.

Further, the design panel 30 has one storage hole 31, a plurality of guide holes 32, and a plurality of insertion holes 33.

The storage hole 31 is a rectangular through hole that passes through the center of the design panel 30. The display section 10 is housed in the housing hole 31 . That is, the display section 10 is adhesively fixed to the cover member 20 and is attached to the design panel 30 while being housed in the housing hole 31 .

As shown in FIGS. 1 to 3, when the cover member 20 is removed from the design panel 30 for the purpose of repair or parts replacement in the display device 100, the guide hole 32 allows the attached double-sided tape 40 to be removed from the cover member. This is a through hole used when pulling out from between 20 and the design panel 30. This guide hole 32 is provided on the outer periphery of the design panel 30. The guide holes 32 are arranged corresponding to one end and the other end of each double-sided tape 40 attached. That is, the guide hole 32 is open at one end and the other end of the area where the double-sided tape 40 is attached.

As described above, two guide holes 32 are provided for one double-sided tape 40 so as to correspond to one end and the other end. Therefore, the display device 100 can set two pulling directions for the double-sided tape 40, and can select one of the two pulling directions. Note that only one guide hole 32 may be provided for one double-sided tape 40 so as to correspond to one end or the other end. Details of the double-sided tape 40 will be described later.

The insertion holes 33 are through holes formed at the four corners of the design panel 30.

Clips

50, 60, 70, and 80 can be inserted into this insertion hole 33. The insertion hole 33 may be provided in at least one of the four corners of the design panel 30. Further, it is sufficient that one clip 80 is provided for each insertion hole 33 . Details of the

clips

50, 60, 70, and 80 will be described later.

Next, the double-sided tape 40 will be explained using FIGS. 3 to 5. In addition, in FIGS. 4 and 5, since the configuration of one end of the double-sided tape 40 and the configuration of the other end of the double-sided tape 40 are the same, only the configuration of the one end is shown as a representative figure. The illustration of the configuration on the other end side is omitted.

As shown in FIG. 4, the double-sided tape 40 is a flat, elongated tape. This double-sided tape 40 has different adhesive strength in its thickness direction and length direction. Therefore, the double-sided tape 40 can be pulled out in its length direction. Furthermore, when attaching the double-sided tape 40 between the cover member 20 and the design panel 30, one end and the other end of the double-sided tape 40 protrude rearward from the guide hole 32 ( (See Figures 3A, 3B, and 5). Further, the double-sided tape 40 has a tape main body 41 and a separator 42.

The tape body 41 has an adhesive surface 41a. The adhesive surfaces 41a are formed on both sides of the tape body 41 in the thickness direction. One adhesive surface 41a is a surface that is attached to the front surface of the design panel 30. The other adhesive surface 41a is a surface that is attached to the rear surface of the cover member 20.

The adhesive force in the thickness direction on the adhesive surface 41a is such that the cover member 20 is affected, for example, when an impact is applied to the display device 100, when vibration occurs in the display device 100, when a user performs a touch operation, etc. The adhesive strength is such that it will not fall off from the design panel 30. Further, the adhesive force in the length direction on the adhesive surface 41a is, for example, smaller than the adhesive force in the thickness direction, and when the cover member 20 is attached between the cover member 20 and the design panel 30, The adhesive strength is such that the tape body 41 can be pulled out from between them.

The separator 42 is pasted on the adhesive surface 41a in advance. Therefore, the separator 42 protects the adhesive surface 41a and prevents the adhesive force from decreasing. The separator 42 is removed from the adhesive surface 41a when the double-sided tape 40 is attached. Furthermore, the separator 42 has a tip 42a and a perforation 42b.

The perforations 42b are formed on one end side and the other end side of the separator 42. This perforation 42b is a breaking line extending in the tape width direction. The tip portion 42a is formed in a region of the separator 42 from the perforation 42b to the tip on one end side or the tip on the other end. Therefore, using the perforations 42b, the separator 42 can be removed from the adhesive surface 41a with the tip 42a remaining on the adhesive surface 41a.

Further, as shown in FIG. 5, the tip portion 42a stuck to the adhesive surface 41a becomes a part that is held by the operator when pulling out the double-sided tape 40 from the guide hole 32. Therefore, when attaching the double-sided tape 40 between the cover member 20 and the design panel 30, at least the tip portion 42a of one end and the other end of the double-sided tape 40 protrudes rearward from the guide hole 32. It would be good if the situation was as follows. The direction of the arrow shown in FIG. 5 indicates the direction in which the double-sided tape 40 is pulled out. Note that when pulling out the double-sided tape 40, if it is desired to improve the gripping force, the tip portion 42a may be peeled off from the adhesive surface 41a.

Next, the

clips

50, 60, 70, and 80 will be explained using FIGS. 2, 3, and 6 to 10.

As shown in FIGS. 2, 3, and 6, the clip 50 is composed of a first clip member 51 and a second clip member 52. The first clip member 51 and the second clip member 52 are made of, for example, elastic resin. Therefore, the first clip member 51 and the second clip member 52 are elastically deformable.

The first clip member 51 can be inserted into and removed from the insertion hole 33 of the design panel 30. The first clip member 51 has a front surface 51a, a locking hole 51b, and a positioning recess 51c.

The front surface 51a becomes flush with the surface of the design panel 30 to which the double-sided tape 40 is attached when the first clip member 51 is inserted into the insertion hole 33. An adhesive member 45 is provided on this front surface 51a. This adhesive member 45 is adhered to the rear surface of the cover member 20. Further, the thickness of the adhesive member 45 is the same as the thickness of the double-sided tape 40. Therefore, the first clip member 51 can hold the cover member 20 via the adhesive member 45. Note that the adhesive member 45 is, for example, double-sided tape or adhesive.

The locking hole 51b is formed in two opposing side walls. Further, the positioning recess 51c is formed in two opposing side walls (side surfaces). The side wall in which the locking hole 51b is formed and the side wall in which the positioning recess 51c is formed are different side walls. The length direction of the positioning recess 51c (the direction in which the positioning recess 51c extends) is the same direction as the direction in which the first clip member 51 is inserted into the insertion hole 33.

On the other hand, the design panel 30 has two positioning protrusions 34. The positioning protrusions 34 are provided on two opposing sides of the insertion hole 33. The two positioning protrusions 34 can be fitted into each of the positioning recesses 51c of the first clip member 51, respectively. In this manner, the display device 100 allows the positioning recess 51c of the first clip member 51 and the positioning protrusion 34 of the insertion hole 33 to fit together, thereby positioning the first clip member 51 with respect to the insertion hole 33. I can do this.

The second clip member 52 has two locking claws 52a. The two locking claws 52a correspond to each locking hole 51b, respectively. The locking claw 52a can lock the first clip member 51 inserted into the insertion hole 33 from the rear side of the design panel 30 and from the outside of the locking hole 51b. At this time, the locking pawl 52a is elastically deformed so as to expand outward of the second clip member 52, and is locked in the locking hole 51b.

On the other hand, the design panel 30 has two ribs 35. The ribs 35 are formed on the rear surface of the design panel 30 so as to protrude rearward from two opposing outer peripheral edges of the insertion hole 33. Further, the ribs 35 correspond to each of the locking holes 51b and each of the locking claws 52a, respectively. Therefore, the rib 35 can hold the locking claw 52a locked in the locking hole 51b by sandwiching it between the rib 35 and the locking hole 51b. As a result, the rib 35 and the second clip member 52 can prevent the first clip member 51 from falling off from the insertion hole 33.

Therefore, in the display device 100, the cover member 20 adhered to the first clip member 51 can be assembled to the design panel 30 by pressing the locking claw 52a locked in the locking hole 51b with the rib 35. . Furthermore, by removing the locking claw 52a from the locking hole 51b, the display device 100 can move the cover member 20 forward with respect to the design panel 30 with the first clip member 51 still attached. It can be removed.

As shown in FIGS. 2 and 7, the clip 60 is composed of a first clip member 61 and a second clip member 62. The first clip member 61 and the second clip member 62 are made of, for example, elastic resin. Therefore, the first clip member 61 and the second clip member 62 are elastically deformable.

The first clip member 61 can be inserted into and removed from the insertion hole 33 of the design panel 30. This first clip member 61 has a front surface 61a and a clip through hole 61b.

The front surface 61a becomes flush with the surface of the design panel 30 to which the double-sided tape 40 is attached when the first clip member 61 is inserted into the insertion hole 33. An adhesive member 45 is provided on this front surface 61a (see FIG. 1B). This adhesive member 45 is adhered to the rear surface of the cover member 20. Therefore, the first clip member 61 can hold the cover member 20 via the adhesive member 45. The clip through hole 61b is a hole that penetrates the side wall of the first clip member 61. The penetrating direction of the clip through hole 61b is orthogonal to the inserting direction of the first clip member 61 into the insertion hole 33, in other words, the penetrating direction of the insertion hole 33.

The second clip member 62 can be inserted into the clip through hole 61b of the first clip member 61 in the length direction. Further, the second clip member 62 has a panel contact portion 62a. The panel contact portions 62a are formed at both lengthwise ends of the second clip member 62, respectively. This panel contact portion 62a is formed to protrude from the front surface of the second clip member 62 toward the design panel 30 side.

On the other hand, the design panel 30 has two clip contact parts 36. The clip abutting portion 36 is formed on the back surface of the design panel 30 so as to protrude rearward from two opposing outer peripheral edges of the insertion hole 33. Further, the clip abutting portions 36 correspond to each opening of the clip through hole 61b and each panel abutting portion 62a, respectively. Therefore, the panel contact portion 62a can sandwich and hold the panel contact portion 62a of the second clip member 62 that has passed through the clip through hole 61b between the panel contact portion 62a and the clip through hole 61b. At this time, the second clip member 62 is held while being warped (elastically deformed) such that the panel contact portion 62a that contacts the clip contact portion 36 is displaced rearward. As a result, the clip contact portion 36 and the second clip member 62 can prevent the first clip member 61 from falling off from the insertion hole 33.

Therefore, in the display device 100, the cover member 20 bonded to the first clip member 61 is pressed by the clip contact portion 36 pressing the panel contact portion 62a of the second clip member 62 that has passed through the clip through hole 61b. , can be assembled to the design panel 30. Furthermore, by removing the second clip member 62 from the clip through hole 61b, the display device 100 can move the cover member 20 forward with respect to the design panel 30 with the first clip member 61 still attached. It can be removed.

As shown in FIGS. 2 and 8, the clip 70 is composed of a first clip member 71 and a second clip member 72. The first clip member 71 and the second clip member 72 are made of resin or metal, for example.

The first clip member 71 can be inserted into and removed from the insertion hole 33 of the design panel 30. This first clip member 71 has a front surface 71a and a screw hole (clip side screw hole) 71b.

The front surface 71a becomes flush with the surface of the design panel 30 to which the double-sided tape 40 is attached when the first clip member 71 is inserted into the insertion hole 33. An adhesive member 45 is provided on this front surface 71a (see FIG. 1B). This adhesive member 45 is adhered to the rear surface of the cover member 20. Therefore, the first clip member 51 can hold the cover member 20 via the adhesive member 45. The screw hole 71b is provided on the rear surface of the first clip member 71.

The second clip member 72 is an L-shaped flat member. This second clip member 72 has

screw holes

72a and 72b. The screw holes (panel screw holes) 72b are provided, for example, at one end and the other end of the second clip member 72. The screw hole (clip screw hole) 72a is provided, for example, between two screw holes 72b. This screw hole 72a corresponds to the screw hole 71b of the first clip member 71. Therefore, the second clip member 72 is attached to the first clip member 71 by fastening a screw (not shown) passed through the screw hole 72a to the screw hole 71b of the first clip member 71.

Although the second clip member 72 is L-shaped, it is not limited to this shape, and may be, for example, circular, oval, rectangular, or frame-shaped. I don't mind. Moreover, it is sufficient if there are one or

more screw holes

72a, 72b.

On the other hand, the design panel 30 has screw holes (panel side screw holes) 37. The screw hole 37 is provided on the rear surface of the design panel 30. This screw hole 37 corresponds to the two screw holes 72b in the second clip member 72. Note that in FIG. 8A, the first screw hole 37 is visible, but the second screw hole 37 is hidden by the first clip member 71 and is not visible. Therefore, the second clip member 72 is attached to the design panel 30 by fastening a screw (not shown) passing through the screw hole 72b into the screw hole 37 of the design panel 30.

Therefore, in the display device 100, the first clip member 71 screwed to the second clip member 72 is inserted into the insertion hole 33 of the design panel 30, and the second clip member 72 is screwed to the design panel 30. The cover member 20 adhered to the first clip member 71 can be assembled to the design panel 30. In addition, the display device 100 allows the cover member 20 and the first clip member 71 to be bonded to the design panel 30 by releasing the screws between the first clip member 71 and the second clip member 72. It can be removed while facing forward.

As shown in FIGS. 2 and 9, the clip 80 is made of, for example, elastic resin. Therefore, the clip 80 is elastically deformable. Further, the clip 80 can be inserted into and removed from the insertion hole 33 of the design panel 30. The clip 80 has a front surface 80a, a side wall 80b, and a locking portion 80c.

The front surface 80a becomes flush with the surface of the design panel 30 to which the double-sided tape 40 is attached when the clip 80 is inserted into the insertion hole 33. An adhesive member 45 is provided on this front surface 80a (see FIG. 1B). This adhesive member 45 is adhered to the rear surface of the cover member 20. The clip 80 can hold the cover member 20 via the adhesive member 45.

The side walls 80b each extend rearward from two opposing sides of the front surface 80a. The front end of each side wall 80b is connected to two sides of the front surface 80a, respectively. On the other hand, the rear end of each side wall 80b is a free end. The locking portion 80c is provided at a rear end that is a free end of the side wall 80b. The locking portion 80c is formed to protrude outward from the front surface 80a from the rear end of the side wall 80b. Therefore, the rear end of the side wall 80b elastically deforms toward the inside or outside of the side wall 80b (clip 80) from its front end as a base point. Along with this, the locking portions 80c are displaced toward or away from each other.

On the other hand, the design panel 30 has a protrusion 38. The protruding portion 38 is formed on the back surface of the design panel 30 so as to protrude rearward from two opposing outer peripheral edges of the insertion hole 33. These two protruding parts 38 correspond to each side wall 80b and each locking part 80c of the clip 80. Therefore, when the clip 80 passes between the protrusions 38 and is inserted into the insertion hole 33, the locking part 80c is formed in the protrusion 38. At this time, each protrusion 38 faces each side wall 80b. As a result, the protrusion 38 can prevent the clip 80 from falling out of the insertion hole 33.

Therefore, in the display device 100, the cover member 20 adhered to the clip 80 can be assembled to the design panel 30 by locking the locking portion 80c of the clip 80 to the protrusion 38 of the design panel 30. Further, the display device 100 elastically deforms the locking portions 80c of the clip 80 so as to approach each other, and removes the locking portions 80c from the protrusion 38, thereby attaching the cover member 20 to the design panel 30. can be removed forward with the clip 80 still attached.

Here, in the display device 100, the linear expansion coefficient of the cover member 20 and the linear expansion coefficient of the design panel 30 are often different from each other. For example, if the linear expansion coefficient of the cover member 20 is larger than that of the design panel 30 and the display device 100 is kept at a high temperature, the cover member 20 will warp significantly. Furthermore, if the linear expansion coefficient of the cover member 20 is smaller than that of the design panel 30 and the display device 100 is kept at a low temperature, the cover member 20 will warp significantly.

FIG. 10 is a diagram showing how the cover member 20 warps when the display device 100 is kept at a high temperature. The white arrow in FIG. 10 indicates the direction of thermal expansion of the cover member 20. The two-dot chain arrow in FIG. 10 indicates the direction of stress acting on the cover member 20. The solid arrow in FIG. 10 indicates the direction in which the cover member 20 is warped. As shown in FIG. 10, when the linear expansion coefficient of the cover member 20 is larger than that of the design panel 30 and the display device 100 is kept at a high temperature, the cover member 20 will warp significantly. At this time, the four corners of the cover member 20 experience the greatest warpage (the portions surrounded by the dashed lines in Fig. 10). This is true even when the linear expansion coefficient of the cover member 20 is smaller than that of the design panel 30 and the display device 100 is kept at a low temperature.

In contrast, the display device 100 includes

clips

50, 60, 70, and 80 at the four corners of the design panel 30, and the

clips

50, 60, 70, and 80 adhere the four corners of the cover member 20 using the adhesive member 45. That's what I do. Therefore, the display device 100 can suppress the warpage of the cover member 20 and prevent the cover member 20 from lifting with respect to the design panel 30.

Therefore, when the display device 100 has the above-described configuration, when the cover member 20 and the design panel 30 are assembled, the double-sided tape 40 is first applied to a predetermined attachment position on the outer periphery of the design panel 30. That is, the separator 42 corresponding to one adhesive surface 41a of the double-sided tape 40 is removed leaving the tip 42a. Then, one adhesive surface 41a is attached to the outer peripheral edge of the design panel 30.

Furthermore, one adhesive surface 41a of the double-sided tape 40 is pasted, and the tip 42a is inserted into the guide hole 32. At this time, the tip portion 42a of the double-sided tape 40 is pulled out backward from the guide hole 32.

Next, the cover member 20 to which the display section 10 is adhered is attached to the design panel 30 via the double-sided tape 40. That is, the separator 42 corresponding to the other adhesive surface 41a of the double-sided tape 40 is removed leaving the tip 42a. Then, the cover member 20 is adhered to the other adhesive surface 41a of the double-sided tape 40 applied to the design panel 30.

At this time, the adhesive member 45 is provided in advance on the

front surfaces

51a, 61a, 71a, 80a of the

clips

50, 60, 70, 80. Therefore, the cover member 20 is affixed to the design panel 30 via the double-sided tape 40 and is also affixed to the design panel 30 via the adhesive member 45.

On the other hand, in the display device 100, the display section 10 and its peripheral parts may be repaired or replaced. In this case, first, the double-sided tape 40 that has been pulled out from the guide hole 32 is pulled out from the guide hole 32 toward the rear.

Furthermore, in the clip 50, the lock between the first clip member 51 and the second clip member 52 is released. In the clip 60, the lock between the first clip member 61 and the second clip member 62 is released. In the clip 70, the screwing between the first clip member 71 and the second clip member 72 is released. In the clip 80, the lock between the locking portion 80c and the protruding portion 38 of the design panel 30 is released.

Next, the cover member 20 is removed from the design panel 30. At this time, the cover member 20 is removed from the design panel 30 with the

first clip members

51, 61, 71 and the clip 80 adhered by the adhesive member 45.

Then, in the display device 100, when the repair or replacement of the display section 10 and its peripheral parts is completed, the double-sided tape 40 is attached to a predetermined attachment position on the outer periphery of the design panel 30. At this time, all of the double-sided tape 40 used last time has been completely pulled out, so there is no need to remove the remains of the double-sided tape 40 used last time before applying the double-sided tape 40 used this time. The following assembly procedure is the same as that described above, so a description thereof will be omitted.

As described above, the display device 100 according to the first embodiment has a structure that covers the front surface of the display section 10 and the front surface of the design panel 30, and the outer peripheral edge of the front surface of the design panel 30. The double-sided tape includes cover members 20 that are adhered to each other with double-sided tape 40, and a guide hole 32 that opens in the design panel 30 and allows the pasted double-sided tape 40 to be pulled out toward the rear of the design panel 30. A separator 42 that protects the adhesive surface 41a of the double-sided tape 40 is attached to the tip of the double-sided tape 40 that protrudes rearward from the guide hole 32. Therefore, the display device 100 can pull out the double-sided tape 40. As a result, the display device 100 can improve the ease of reassembling the cover member 20 and the design panel 30.

The display device 100 is removably inserted into the insertion hole 33 provided in the design panel 30, and the adhesive members 45 provided on the

front surfaces

51a, 61a, 71a, and 80a are adhered to the rear surface of the cover member 20. The

clips

50, 60, 70, and 80 are provided. Therefore, the display device 100 can suppress warping of the cover member 20.

In the display device 100, the insertion holes 33 are provided at the four corners of the design panel 30. For this reason, the display device 100 can hold the portion of the cover member 20 where the warp is greatest, so that the warp of the cover member 20 can be efficiently suppressed.

In the display device 100, the adhesive force in the length direction of the double-sided tape 40 is smaller than the adhesive force in the thickness direction of the double-sided tape 40. Therefore, in the display device 100, the cover member 20 and the design panel 30 can be properly bonded together using the double-sided tape 40, and the double-sided tape 40 can be easily pulled out in the length direction.
