JP 2001-183633 A

  In vehicle-mounted display devices such as car navigation devices, in recent years, large design panels that also serve as part of a vehicle instrument panel are increasing in design. In order to bond the cover part to the large design panel, a large work space is required. In addition, there was a high possibility of damaging the design panel during bonding, and workability was also poor.

  In addition, it is difficult to remove the strong double-sided adhesive tape that bonds the design panel and the cover part. Therefore, even if either the design panel or the cover part is damaged, both must be replaced together. It was. For this reason, it is not possible to replace only the damaged parts and reuse the parts that are not damaged, and the parts cost at the time of repair is high.

  The present invention has been made to solve the above-described problems. In a display device having a design panel and a cover part, the cost of parts during repair, the reduction of work space, and workability are reduced. The purpose is to improve.

  The display device according to the present invention includes a liquid crystal display, a panel in which an opening is formed in a portion facing the display area of the liquid crystal display, a liquid crystal display housing, and an edge of the opening of the panel overlapping the opening. A holder fixed so as not to become a cover, and a cover part that is bonded to the holder with a double-sided adhesive tape and covers the opening.

  According to this invention, the cover part is bonded to the holder, and the holder is fixed to the panel, whereby the cover part-attached holder and the panel can be easily disassembled. As a result, when it is necessary to replace the panel, the holder with the cover part can be removed from the panel and only the panel can be replaced. When the cover part needs to be replaced, only the holder with the cover part is replaced. Therefore, compared with the conventional structure in which both the panel and the cover part need to be replaced, the parts cost at the time of repair can be reduced. Further, since the cover part is bonded not to a large panel but to a holder smaller than the panel, the work space can be reduced, and there is no fear of damaging the panel at the time of bonding, and workability is improved.

Embodiment 1 FIG.
1 and 2 are exploded perspective views showing a configuration example of a display device 1 according to Embodiment 1 of the present invention. FIG. 1 shows a state in which the display device 1 is viewed from the front side, and FIG. 2 shows a state in which the display device 1 is viewed from the back side. FIG. 3 is a front view of the display device 1 and shows the design surface side of the panel 40.
The display device 1 according to the first embodiment includes a cover component 10, a double-sided adhesive tape 20, a holder 30, a panel 40, a display holder 50, and a liquid crystal display 60.

  The liquid crystal display 60 has a display area 61 for displaying an image on the front. The display holder 50 is fixed to the panel 40 while holding the liquid crystal display 60. An opening 51 is formed in a portion of the display holder 50 that faces the display area 61 so that the display holder 50 does not hide the display area 61 of the liquid crystal display 60. Similarly, an opening 41 is formed in a portion of the panel 40 that faces the display area 61 so that the panel 40 does not hide the display area 61 of the liquid crystal display 60. The opening 41 in the panel 40 is covered with the cover component 10.

The display holder 50 is a metal part and is connected to the ground of the vehicle.
Note that the liquid crystal display 60 may be fixed to the panel 40 without using the display holder 50, or the liquid crystal display 60 may be fixed to the cover component 10.

  The panel 40 is a resin part, for example. In the illustrated example, the sizes of the cover part 10, the holder 30, the panel 40, the display holder 50, and the liquid crystal display 60 are substantially the same. For example, when the panel 40 is used as a part of a vehicle instrument panel, the panel is used. Only 40 may be enlarged.

  FIG. 4 is a perspective view showing a state in which the double-sided adhesive tape 20 is bonded to the holder 30. FIG. 5 is a perspective view showing a state in which the cover component 10 and the holder 30 are bonded with the double-sided adhesive tape 20.

The cover component 10 covers the opening 41 of the panel 40 and protects the display area 61 of the liquid crystal display 60. In the cover component 10, a light transmitting portion 11 that transmits light is formed in a portion facing the display area 61 of the liquid crystal display 60, and a light non-transmitting portion 12 that does not transmit light is formed around the light transmitting portion 11. Yes. The holder 30 is for fixing the cover part 10 to the panel 40. The cover component 10 is bonded to one surface of the holder 30 with the double-sided adhesive tape 20, and the other surface of the holder 30 is fixed to the panel 40. An opening 31 is formed in a portion of the holder 30 that faces the display area 61 and the opening 41 so that the holder 30 does not hide the display area 61 of the liquid crystal display 60. Further, the holder 30 has a shape hidden by the light-impermeable portion 12 so that it cannot be seen by the user on the front side.
Note that the cover component 10 may be provided with a touch sensor or a touch panel.

Here, the structural example of the holder 30 is demonstrated using FIGS.
As shown in FIG. 6, the holder 30 is an annular frame member having a shape corresponding to the outer shape of the cover component 10. 6 and FIGS. 1, 2, 4 and 5, the holder 30 has the same shape.
In Embodiment 1, since the opening 41 of the panel 40 is rectangular, the outer shape of the cover component 10 covering the opening 41 is also substantially rectangular, and the holder 30 is also configured as a substantially rectangular frame. The holder 30, which is an annular frame member, has an opening 31 and has a shape that does not overlap the opening 41 of the panel 40 and the display area 61 of the liquid crystal display 60.

Further, for example, as shown in FIG. 7, two portions of the holder 30 that is an annular frame member corresponding to the outer shape of the cover part 10 are cut out, and the holder 30a, 30b may be configured. The holders 30 a and 30 b are arranged at an interval corresponding to the opening 31 so as not to overlap the opening 41 of the panel 40 and the display area 61 of the liquid crystal display 60.
In the example of FIG. 7, the holders 30 a and 30 b are provided on the left and right sides of the cover component 10, but may be provided on the upper and lower sides.

For example, as shown in FIG. 8, a holder 30 c that is a U-shaped frame member may be configured by cutting out one portion of the holder 30 that is an annular frame member corresponding to the outer shape of the cover component 10. The holder 30 c that is a U-shaped frame member has an opening 31, and has a shape that does not overlap the opening 41 of the panel 40 and the display area 61 of the liquid crystal display 60.
In the example of FIG. 8, the upper side of the holder 30c is cut out, but the right side, the left side, or the lower side may be cut out.

For example, as shown in FIG. 9A, reinforcing ribs 32 may be formed on the holder 30, which is an annular frame member corresponding to the outer shape of the cover component 10, avoiding the display area 61 of the liquid crystal display 60. . In this example, the display area 61 is divided into left and right parts, and it is assumed that no image is displayed on the part of the display area 61 where the reinforcing ribs 32 overlap.
FIG. 9B is a front view showing a state in which the cover component 10 is bonded to the holder 30 of FIG. In the cover component 10, the light-impermeable portion 12 is formed not only in the portion facing the annular frame member of the holder 30 but also in the portion facing the reinforcing rib 32. Thereby, even when the reinforcing rib 32 is formed on the holder 30, the holder 30 and the reinforcing rib 32 cannot be seen from the user on the front side.
Further, the reinforcing rib 32 may be formed on the holder 30c which is the U-shaped frame member shown in FIG. 8 while avoiding the display area 61 of the liquid crystal display 60.

As described above, the holder 30 only needs to have a shape that does not overlap the opening 41 of the panel 40 and the display area 61 of the liquid crystal display 60, and is not limited to the above shape.
When the cover component 10 and the holder 30 are fixed to the back surface of the panel 40, the outer shape of the holder 30 may be arbitrary because the outer shape of the holder 30 is hidden by the panel 40 and is not visible to the user. On the other hand, when the cover component 10 and the holder 30 are fixed to the front surface of the panel 40, the outer shape of the holder 30 is made smaller than the outer shape of the cover component 10 so that it cannot be seen by the user.
1 to 9 and FIGS. 10 to 15 to be described later, configuration examples for fixing the cover component 10 and the holder 30 to the front surface of the panel 40 are shown.

The holder 30 may be a resin part, a metal part, or an integrally molded part of resin and metal.
By forming the holder 30 with a resin such as PC (polycarbonate), PC + ABS (acrylonitrile butadiene styrene), PMMA (polymethyl methacrylate), or ABS, positioning protrusions 33a and 33b described later, heat welding The convex portions 34a to 34i and the claws 35a to 35d can be easily formed.
When the holder 30 is made of metal such as sheet metal, rigidity can be ensured. Further, by connecting the holder 30 that is a metal part to a display holder 50 that is also a metal part, and connecting the holder 30 or the display holder 50 to the ground of the vehicle, static electricity is generated when the user uses the display device 1. Even if it occurs, the electronic components such as the liquid crystal display 60 accommodated in the panel 40 can be prevented from being destroyed.
When the holder 30 is configured as an integrally molded part by resin or metal insert molding or outsert molding, both of the advantages of the resin part and the metal part can be obtained. Moreover, although it will become heavy if the holder 30 is comprised only with a metal, if it is an integrally molded part, a part of metal can be replaced with resin and weight reduction can be achieved.

Next, a structure for fixing the holder 30 to which the cover component 10 is bonded with the double-sided adhesive tape 20 to the panel 40 will be described.
FIG. 10 is a perspective view illustrating a configuration example of the back side of the holder 30 illustrated in FIG. 6. FIG. 11 is a perspective view illustrating a configuration example of the front side of the panel 40 that fixes the holder 30 illustrated in FIG. 6. FIG. 12 is a perspective view showing a configuration example on the back side of the panel 40 to which the holder 30 with the cover part 10 is fixed. Further, FIG. 13 (a) shows a view of the peripheral structure of the screw fixing surface 37 shown in FIG. 12 in the direction of arrow B, and FIG. 13 (b) shows a view of C in the direction of arrow C. ).

  As shown in FIG. 11, a holder fixing portion 42 for fixing the holder 30 is formed at the edge of the opening 41 of the panel 40. The front side of the holder fixing portion 42 has a concave shape corresponding to the thickness of the cover component 10, the double-sided adhesive tape 20 and the holder 30. Since this holder fixing part 42 is hidden behind the light-impermeable part 12 of the cover part 10, it cannot be seen from the user.

The operator attaches the double-sided adhesive tape 20 to the front surface of the holder 30, attaches the cover component 10 thereto, and then attaches the holder 30 with the cover component 10 to the holder fixing portion 42 from the front of the panel 40 and fixes it. . Alternatively, the operator attaches the double-sided adhesive tape 20 to the back surface of the cover component 10, attaches the holder 30 thereto, and then attaches the holder 30 with the cover component 10 to the holder fixing portion 42 from the front of the panel 40, Fix it.
By assembling the holder 30 with the cover part 10 on the front side of the holder fixing part 42, the flat display device 1 can be realized without a step between the panel 40 and the cover part 10 in front of the panel 40. In addition, you may make the design which gave the level | step difference to the panel 40 and the cover component 10 by adjusting the thickness of the holder fixing | fixed part 42. FIG.

As shown in FIG. 10, positioning convex portions 33 a and 33 b are formed on the back surface of the holder 30. The positioning convex portion is a boss, a rib or the like. On the other hand, as shown in FIG. 11, positioning concave portions 43 a and 43 b for positioning the holder 30 and the panel 40 by fitting the positioning convex portions 33 a and 33 b are formed on the front surface of the panel 40.
In the illustrated example, positioning unevenness is formed on the left and right sides of the holder 30 and the panel 40, and the holder 30 and the opening 41 are positioned in the left-right direction. Positioning may be performed.
Further, the positioning convex portions 33 a and 33 b may be formed on the panel 40, and the positioning concave portions 43 a and 43 b may be formed on the holder 30.

  Note that positioning may be performed by a method other than using positioning unevenness. For example, the outer shape of the cover component 10 may be dimensioned to fit in the opening 41 of the panel 40 without a gap, and positioning may be performed by the outer shape of the cover component 10 and the opening 41 of the panel 40. Further, for example, a jig may be installed around the opening 41 of the panel 40, and positioning with respect to the opening 41 may be performed by applying the outer shape of the cover component 10 to the jig.

  The holder 30 with the cover component 10 and the panel 40 are fixed by screw fixing, claw fixing, or heat welding that can be disassembled after fixing. In the example of FIGS. 10 to 12, for the sake of explanation, the holder 30 and the panel 40 are fixed by these three types of fixing methods, but the holder 30 and the panel 40 are fixed by at least one of these three types of fixing methods. Fix it.

For example, for heat welding, as shown in FIG. 10, heat welding convex portions 34 a to 34 i are formed on the back surface of the holder 30. On the other hand, as shown in FIG. 11, the holder fixing portion 42 of the panel 40 is formed with hot welding holes 44a to 44i for inserting the hot welding convex portions 34a to 34i. One heat welding convex part and one heat welding hole which inserts the said heat welding convex part comprise 1 set of heat welding parts.
As shown in FIG. 12, on the back side of the panel 40, the tip side of the hot welding convex portion 34 a penetrating the hot welding hole 44 a is heat welded. The remaining heat-projecting projections 34 b to 34 i and the heat-welding holes 44 b to 44 i are similarly heat-welded, whereby the holder 30 with the cover component 10 is fixed to the panel 40.

  When the holder 30 with the cover part 10 or the panel 40 is replaced when the display device 1 is repaired, the heat-welded portion is cut and the holder 30 with the cover part 10 is removed from the panel 40. The same part cannot be heat-welded. Therefore, when the holder 30 with the cover part 10 is fixed to the panel 40, some of the heat-welding projections 34a to 34i and the heat-welding holes 44a to 44i are left without being heat-welded as spares for repair. You may keep it.

Further, the heat welding convex portions 34 a to 34 i may be formed in the panel 40 and the heat welding holes 44 a to 44 i may be formed in the holder 30.
In the illustrated example, since the holder 30 with the cover part 10 is fixed to the front side of the holder fixing portion 42, the heat welding holes 44 a to 44 i are formed in the panel 40, and the heat welding convex portion 34 a is formed on the back surface of the holder 30. In contrast, in the case where the holder 30 with the cover component 10 is fixed to the back side of the holder fixing portion 42, the heat welding convex portions 34a to 34i are formed on the back surface of the panel 40, 30 may be provided with hot welding holes 44a to 44i.

Further, for example, for fixing the claws, claws 35 a to 35 d are formed on the back surface of the holder 30 as shown in FIG. 10. On the other hand, as shown in FIG. 11, notches 45 a to 45 d that avoid the claws 35 a to 35 d are formed in the holder fixing portion 42 of the panel 40.
As shown in FIG. 12, on the back side of the panel 40, the claw 35a protruding from the holder 30 engages with the edge of the notch 45a. The holders 30 with the cover parts 10 are fixed to the panel 40 by engaging the remaining claws 35b to 35d and the notches 45b to 45d in the same manner.
As in the case of heat welding, the nails 35 a to 35 d may be formed on the panel 40 and the notches 45 a to 45 d may be formed on the holder 30 in the nail fixing.

Further, for example, a screw hole 36a is formed on the back surface of the holder 30 for screw fixing, as shown in FIG. Further, as shown in FIG. 11, screw holes 46 a are also formed in the holder fixing portion 42 of the panel 40. The screw hole 36a may be formed by standing a screw boss on the back surface of the holder 30.
As shown in FIG. 12, on the back side of the panel 40, a screw 30 (not shown) is fastened to screw holes 36 a and 46 a that are in a direction perpendicular to the surface of the cover component 10. Is fixed to the panel 40.

If there is no space for fastening screws in the direction perpendicular to the surface of the cover component 10 on the back side of the panel 40, the screws may be fastened in the horizontal direction on the surface of the cover component 10.
When fastening the screws in the horizontal direction, for example, as shown in FIG. 10, a screw fixing surface 37 is formed on the back surface of the holder 30, and a screw hole 36 b is formed in the screw fixing surface 37. The screw hole 36 b may be formed by raising a screw boss on the screw fixing surface 37. On the other hand, as shown in FIG. 11, a through hole 47 through which the screw fixing surface 37 passes is formed in the holder fixing portion 42 of the panel 40. A screw hole 46 b is formed at a position facing the screw hole 36 b of the screw fixing surface 37 on the side wall of the panel 40.
As shown in FIGS. 12, 13 (a) and 13 (b), screws (not shown) are provided in screw holes 36 b and 46 b which are in the horizontal direction to the surface of the cover component 10 on the back side of the panel 40. The holder 30 with the cover part 10 is fixed to the panel 40 by fastening.

  When the display device 1 is used in a specific environment such as an environment where the temperature changes from a low temperature to a high temperature, such as a vehicle, or a high humidity environment, the panel 40 is deformed over time, and the panel 40 There is a possibility that the step of the cover component 10 becomes large. In order to suppress such deformation of the panel 40, it is desirable to increase the number of fixing points between the panel 40 and the holder 30 with the cover component 10. However, increasing the number of fixing points with screws increases the number of parts and the number of assembly steps, so it is desirable to increase the number of fixing points with heat welding or claws.

  14 is a cross-sectional view of the display device 1 taken along the line AA in FIG. In the display device 1 shown in FIG. 14, the annular holder 30 shown in FIG. 6 is used. A touch sensor 70 is installed on the back surface of the cover component 10, and an FPC (flexible printed circuit board) 71 of the touch sensor 70 passes through a gap between the holder 30 and the liquid crystal display 60 and a gap between the panel 40 and the liquid crystal display 60. It is pulled out to the back side.

The light emitted from the liquid crystal display 60 may leak outside through the gap between the cover component 10 and the panel 40 as indicated by an arrow D. However, since the holder 30 that is an annular frame member is in surface contact with the edge of the opening 41 over the entire circumference, light leakage can be prevented. In this example, since the holder fixing portion 42 is formed at the edge of the opening 41 of the panel 40, the holder 30 comes into surface contact with the holder fixing portion 42.
Light leakage can be prevented even if the holder 30 and the panel 40 are in line contact, but light leakage is more reliably prevented when the contact area between the holder 30 and the panel 40 is wider as in the surface contact shown in FIG. Is possible.

  In addition, when using the U-shaped frame member or two members which a part of the annular frame member was cut out like the holders 30a, 30b and 30c shown in FIG. 7 or FIG. The surface contact between 30 and the panel 40 is interrupted. In that case, for example, as shown in the cross-sectional view of FIG. 15, the cover part 10 is contacted at a position corresponding to the notched portion of the holder 30 a or the holders 30 b and 30 c in the edge of the opening 41 of the panel 40. What is necessary is just to make the structure which forms the protrusion wall 48 to prevent and the light leakage shown by the arrow D. FIG. For example, when the holders 30a and 30b shown in FIG. 7 are used, the upper and lower sides of the opening 41 are formed by forming protruding walls 48 on the upper and lower two sides of the four sides of the holder fixing portion 42. Light leaking from the left and right can be blocked by the two protruding walls 48 and the holders 30a and 30b.

Further, when static electricity occurs on the front side of the display device 1, the static electricity flows through the resin panel 40 to electronic components such as the touch sensor 70 and the liquid crystal display 60, and these electronic components may be damaged. is there. Therefore, the holder 30 is composed of a metal part or an integrally molded part of resin and metal, and the metal portion of the holder 30 is connected to the display holder 50 by screwing or the like to form a chassis ground. Further, the metal portion of the holder 30 is disposed between the holder fixing portion 42 of the panel 40 and the electronic components such as the touch sensor 70 and the liquid crystal display 60 located inside the holder fixing portion 42. The holder fixing part 42 and the electronic component are partitioned by the part. Thereby, since static electricity does not go from the holder fixing | fixed part 42 to an electronic component but flows through the holder 30, it can prevent that an electronic component is destroyed by static electricity.
Further, the metal portion of the holder 30 can be blocked so that noise generated from the liquid crystal display 60 does not reach the touch sensor 70.

  Next, a configuration example when the holder 30 with the cover component 10 is assembled and fixed from the back side of the panel 40 will be described. FIG. 16 is a cross-sectional view taken along the line AA in FIG. 3 of the display device 1 in which the holder 30 with the cover component 10 is assembled and fixed from the back side of the panel 40.

  As shown in FIG. 16, the cover component 10 is bonded to the front surface of the holder 30 with a double-sided adhesive tape 20. Further, the outer peripheral side of the cover component 10 on the front surface of the holder 30 is fixed to a holder fixing portion 42 that is an edge portion of the opening 41 of the panel 40. The back side of the holder fixing portion 42 has a recessed shape, and the thickness of the holder fixing portion 42 is the same as the thickness of the cover component 10.

In FIG. 16, the operator attaches the double-sided adhesive tape 20 to the front surface of the holder 30, attaches the cover component 10 thereto, and then attaches the holder 30 with the cover component 10 to the holder fixing portion 42 from the back surface of the panel 40. And fix. Alternatively, the operator attaches the double-sided adhesive tape 20 to the back surface of the cover component 10 and attaches the holder 30 thereto, and then attaches the holder 30 with the cover component 10 to the holder fixing portion 42 from the back surface of the panel 40, Fix it.
By assembling the holder 30 with the cover component 10 on the back side of the holder fixing portion 42, the flat display device 1 can be realized without a step between the panel 40 and the cover component 10 in front of the panel 40. In addition, you may make the design which gave the level | step difference to the panel 40 and the cover component 10 by adjusting the thickness of the holder fixing | fixed part 42. FIG.

17 is a cross-sectional view of the display device 1 cut along the line EE in FIG. 3, and FIG. 17A is an example in which the holder 30 with the cover part 10 is assembled and fixed from the front side of the panel 40. 17 (b) is an example in which the holder 30 with the cover component 10 is assembled and fixed from the back side of the panel 40. FIG. With reference to FIG. 17, the case where the holder 30 is fixed to the front surface of the panel 40 and the case where it is fixed to the back surface will be described in comparison.
When the holder 30 is fixed to the front surface of the panel 40 in FIG. 17A, the back surface of the holder 30 comes into contact with the front surface of the panel 40 as indicated by an arrow. It can be used as a fixing space, such as screw fixing. Therefore, the back space of the narrow panel 40 can be used effectively.
On the other hand, when the holder 30 is fixed to the back surface of the panel 40 in FIG. 17B, the portion indicated by the arrow is not the panel 40 but the holder 30, and when the screw boss is raised from the holder 30 in this portion, the structure of the holder 30 is It becomes complicated. In addition, the strength of the configuration example of FIG. 17B is slightly lower than that of the configuration example of FIG. Furthermore, when the holder 30 is configured by a metal part such as a sheet metal, a screw boss or the like cannot be raised, and the structure is restricted.

  Next, a modified example of the display device 1 will be described. FIG. 18 is a cross-sectional view of the modification of the display device 1 taken along the line FF in FIG. 3, and is a modification in which the outer shape of the cover component 10 is larger than the outer shape of the panel 40. In the modification shown in FIG. 18, the entire front surface of the panel 40 has a concave shape corresponding to the thickness of the holder 30, and the holder 30 with the cover component 10 is fixed to the concave shape. In this way, the design may be such that the outer shape of the cover component 10 is the maximum outer shape of the display device 1.

  As described above, according to the first embodiment, the display device 1 includes the liquid crystal display 60 and the panel 40 that accommodates the liquid crystal display 60 in which the opening 41 is formed in a portion facing the display area 61 of the liquid crystal display 60. The holder 30 is fixed to the edge of the opening 41 of the panel 40 so as not to overlap the opening 41, and the cover part is attached to the holder 30 with the double-sided adhesive tape 20 and covers the opening 41. Therefore, disassembly of the holder 30 with the cover component 10 and the panel 40 is simplified. Thereby, when it is necessary to replace the panel 40, the holder 30 with the cover part 10 can be removed from the panel 40 and only the panel 40 can be replaced. When the cover part 10 needs to be replaced, Since only the holder 30 with the cover part 10 can be replaced, the parts cost at the time of repair can be reduced as compared with the conventional structure in which both the panel 40 and the cover part 10 need to be replaced. Incidentally, the panel 40 is generally more frequently replaced than the cover component 10.

  When the cover part 10 is replaced, the holder 30 bonded to the cover part 10 also needs to be replaced. However, since the holder 30 is a cheaper part than the panel 40, both the cover part 10 and the panel 40 are used. The cost of parts can be reduced by exchanging the holder 30 with the cover part 10 rather than exchanging the parts.

  When the panel 40 is replaced, in particular, when the liquid crystal display 60 is directly bonded to the cover component 10 or the touch sensor 70 and the liquid crystal display 60 are directly bonded to the cover component 10, the cover 40 is replaced when the panel 40 is replaced as in the conventional structure. If the component 10 is also replaced, the loss of the component cost is very large. On the other hand, in the display device 1 according to the first embodiment, when the panel 40 is replaced, only the panel 40 can be replaced.

  Even when the panel 40 is made large and used as a part of a vehicle instrument panel or the like, the cover part 10 is bonded not to the large panel 40 but to the holder 30 smaller than the panel 40, so that the work space is reduced. Is possible. Moreover, since there is no fear of damaging the panel 40 at the time of adhesion | attachment of the cover component 10 and the holder 30, workability | operativity improves.

Further, in the conventional structure, when the panel 40 is replaced, there is an operation of bonding the replaced panel 40 and the cover part 10. However, the display device 1 according to the first embodiment does not have the bonding operation, thereby reducing the number of repair steps. it can.
Furthermore, since the display device 1 can be easily disassembled, it becomes easier to verify during development.

  In the present invention, any component of the embodiment can be modified or any component of the embodiment can be omitted within the scope of the invention.
