<First embodiment>
FIG. 1 is a perspective view of a display device 1 according to the first embodiment. The display device 1 is a transmissive liquid crystal display device, and displays an image on the front surface 1a based on image data transmitted from an external device (not shown). The display device 1 is curved convexly toward the -Z side. Specifically, in the display device 1, the cross section of the plane perpendicular to the Y direction is curved convexly toward the -Z side, and the cross section of the plane perpendicular to the X direction is not curved but flat.

FIG. 2 is a side view of the display device 1. In a side view of the display device 1 seen from the −Y side shown in FIG. 2, the front surface 1a of the display device 1 is curved with a substantially constant curvature in a convex shape toward the −Z side. Further, the front surface 1a of the display device 1 is curved convexly at a substantially constant curvature toward the -Z side when viewed in cross section on a plane perpendicular to the Y direction. It goes without saying that the curvature of the front surface 1a is not limited to a substantially constant value. Further, the front surface 1a of the display device 1 is linear in a cross-sectional view of a plane perpendicular to the X direction.

FIG. 3 is a plan view of the display device 1. The front surface 1a of the display device 1 has a display area DA for displaying an image, and a frame area FA around the display area DA. The display area DA has a rectangular shape with the X direction as the longitudinal direction and the Y direction as the lateral direction in plan view. The frame area FA is an area between the periphery of the display area DA and the periphery of the front surface 1a.

FIG. 4 is an exploded perspective view of the display device 1. FIG. 5 is a partially enlarged sectional view of the display device 1 taken along line VV shown in FIG. FIG. 6 is a partially enlarged side view of the display device 1. As shown in FIG. FIG. 6 is a partially enlarged side view of the -X side of the display device 1 viewed from the -Y side. As shown in FIG. 4, the display device 1 includes a support 10, a lighting device 20, a display panel 30, and a cover panel 40.

The support body 10 is box-shaped with an opening on the +Z side, and has a rectangular shape with the X direction as the longitudinal direction and the Y direction as the lateral direction in plan view. The support body 10 is curved convexly toward the -Z side corresponding to the front surface 1a of the display device 1. The support 10 has a bottom wall 11 (see FIG. 5) and side walls 12. The bottom wall 11 is curved convexly toward the -Z side, corresponding to the front surface 1a of the display device 1.

The side wall 12 is located at the periphery of the bottom wall 11 and has a rectangular shape in plan view. The bottom wall 11 and the side wall 12 are integral. The +Z side end of the −Y side side wall 12 has two notches 12a. The end surface of the side wall 12 on the +Z side constitutes a support surface 12b.

The support surface 12b is curved convexly toward the -Z side, corresponding to the front surface 1a of the display device 1. Specifically, the support surface 12b is curved convexly toward the −Z side when viewed in cross section on a plane orthogonal to the Y direction, and is linear when viewed in cross section on a plane orthogonal to the X direction. Further, the support surface 12b is substantially parallel to the front surface 1a of the display device 1, and has a curvature that is substantially equal to the front surface 1a of the display device 1. Furthermore, the support surface 12b has a rectangular frame shape in plan view. The support surface 12b supports the cover panel 40 (details will be described later).

As shown in FIGS. 5 and 6, the side wall 12 has a recess 12c. FIG. 5 shows a cross section of the recess 12c in the -X side wall 12, and FIG. 6 mainly shows the recess 12c in the -Y side wall 12. The recesses 12c are also present in the +X side wall 12 and the +Y side wall 12. Further, the cross-sectional shapes of the recesses 12c in the side wall 12 on the -Y side, the side wall 12 on the +X side, and the side wall 12 on the +Y side have the same cross-sectional shape as the cross-sectional shape of the recess 12c shown in FIG.

The recess 12c is arranged on a surface of the support body 10 other than the support surface 12b. Specifically, the recess 12c is arranged on the plate surface of the side wall 12 that constitutes the outer surface of the support 10. In other words, the recess 12c is arranged on the outer plate surface 12d of the side wall 12 facing outward laterally of the display device 1.

The recessed portion 12c is open toward the outside of the display device 1 in a cross-sectional view. That is, the open side of the recessed portion 12c faces the outside of the display device 1 in a cross-sectional view.

The recessed portion 12c overlaps the support surface 12b in a plan view, that is, in a plan view when the display device 1 is viewed from the cover panel 40 side. In the first embodiment, at least the bottom of the recess 12c overlaps the support surface 12b in plan view.

Further, the recessed portion 12c overlaps the support surface 12b when the display device 1 is viewed from the cover panel 40 side along the direction orthogonal to the support surface 12b. For example, when viewing the display device 1 along an imaginary line that passes through an arbitrary point located on the support surface 12b and is perpendicular to the support surface 12b at that arbitrary point, the recess 12c is located at a position overlapping the support surface 12b. . The recess 12c is located further away from the support surface 12b on the −Z side along the outer plate surface 12d than the support surface 12b.

The recess 12c has a groove shape extending along the support surface 12b. For example, the support surface 12b formed by the end surface of the side wall 12 on the -X side shown in FIG. 5 extends along the Y direction, and the recess 12c shown in FIG. 5 is formed by the end surface of the side wall 12 on the -X side. Like the support surface 12b, it extends along the Y direction.

Further, the support surface 12b constituted by the end face of the side wall 12 on the -Y side shown in FIG. Similar to the support surface 12b formed by the end face of the side wall 12 on the -Y side, the recessed part 12c shown in FIG. It is extending. The recess 12c in the side wall 12 on the -Y side shown in FIG. 6 is continuous with the recess 12c on the side wall 12 on the -X side shown in FIG.

The recess 12c may be continuously formed in a groove shape along the support surface 12b in the side wall 12 on the −Y side, the side wall 12 on the −X side, the side wall 12 on the +Y side, and the side wall 12 on the +X side. Note that the recessed portion 12c may be formed in parts. In this case, the recess 12c may be in the shape of a hole with a bottom or may be in the shape of a hole that penetrates the side wall 12. It goes without saying that the position of the recess 12c is not limited to the above position. For example, the recess 12c may be located in the bottom wall 11.

As shown in FIG. 5, in the outer plate surface 12d of the side wall 12, a region 12d1 between the recess 12c and the support surface 12b is larger than a region between the recess 12c and the bottom surface of the support 10. Located on the lateral lateral side.

Further, the side wall 12 further includes a protrusion 12e that protrudes inside the support body 10. The protruding portion 12e is arranged on the inner plate surface 12f of the side wall 12 facing inward of the support body 10. The protrusion 12e supports the peripheral edge of the display panel 30 via a cushion member C, which is a foamed material, for example.

The lighting device 20 emits light toward the display panel 30. The lighting device 20 is disposed on the inner bottom surface of the support body 10, and is curved convexly toward the -Z side in correspondence with the bottom wall 11. The lighting device 20 includes a reflective sheet 21, a light guide plate 22, a first lens sheet 23, a second lens sheet 24, and a diffusion sheet 25. The reflective sheet 21, the light guide plate 22, the first lens sheet 23, the second lens sheet 24, and the diffusion sheet 25 are laminated in this order from the -Z side to the +Z side.

Light emitted from a light emitting body (for example, a light emitting diode; not shown) disposed inside the support body 10 and on the lateral outside of the light guide plate 22 enters the light guide plate 22 . The reflective sheet 21 reflects the light emitted from the −Z side surface of the light guide plate 22 toward the +Z side.

The first lens sheet 23 and the second lens sheet 24 improve the directivity of light emitted from the +Z side surface of the light guide plate 22. The diffusion sheet 25 appropriately diffuses the light emitted from the first lens sheet 23 and the second lens sheet 24. Note that the lighting device 20 does not need to include the reflective sheet 21, the first lens sheet 23, the second lens sheet 24, and the diffusion sheet 25.

The display panel 30 is located on the +Z side from the lighting device 20. The display panel 30 is attached to the -Z side surface of the cover panel 40 at a position inside the support surface 12b in the X direction and in the Y direction, and at a position overlapping with the lighting device 20 in the Z direction.

The display panel 30 modulates the light emitted from the lighting device 20 and displays an image on the +Z side surface. The area where an image is displayed on the display panel 30 substantially coincides with the display area DA in plan view.

The display panel 30 includes a first polarizing plate 31, a first substrate 32, a liquid crystal layer 33 having a plurality of liquid crystal molecules (not shown), a second substrate 34, and a second polarizing plate 35. The first polarizing plate 31, the first substrate 32, the liquid crystal layer 33, the second substrate 34, and the second polarizing plate 35 are stacked in this order from the −Z side to the +Z side.

The light emitted from the illumination device 20 enters the first polarizing plate 31. The first polarizing plate 31 converts the incident light into linearly polarized light. The light that has passed through the first polarizing plate 31 passes through the first substrate 32 and enters the liquid crystal layer 33 . The light incident on the liquid crystal layer 33 is modulated by controlling the orientation of liquid crystal molecules based on image data transmitted from an external device.

The light that has passed through the liquid crystal layer 33 passes through the second substrate 34 and enters the second polarizing plate 35 . The second polarizing plate 35 transmits or blocks the incident light depending on the state of the light modulated by the liquid crystal layer 33. As a result, an image is displayed on the +Z side surface of the display panel 30.

Note that the display panel 30 and the lighting device 20 are electrically connected to an external device via, for example, a flexible printed circuit board (FPC: FLEXIBLE PRINTED CIRCUITS; not shown). The flexible printed circuit board passes through the cutout 12a of the support 10.

Cover panel 40 protects display panel 30. The cover panel 40 is made of translucent glass. Note that the cover panel 40 may be made of resin having translucency.

The cover panel 40 has a plate shape having a +Z side surface and a −Z side surface corresponding to two plate surfaces that are located on opposite sides in the Z direction and parallel to each other. The +Z side surface of the cover panel 40 is the front surface 1a of the display device 1. The -Z side surface of the cover panel 40 is a supported surface 40a. The outer peripheral edge of the supported surface 40a is located laterally outward of the display device 1 than the outer peripheral edge of the supporting surface 12b and the recess 12c.

The front surface 1a of the display device 1 is curved as described above, and the cover panel 40 is curved corresponding to the curvature of the front surface 1a. Further, the support surface 12b of the support body 10 is curved in accordance with the curvature of the front surface 1a. That is, the cover panel 40 is curved corresponding to the support surface 12b of the support body 10. That is, the cover panel 40 is curved convexly toward the -Z side when viewed in cross section on a plane perpendicular to the Y direction. In other words, the cover panel 40 is curved in a convex manner toward the support body 10 side.

The supported surface 40a and the supporting surface 12b are bonded together via an adhesive tape TP. The supported surface 40a faces the supporting surface 12b. Specifically, the peripheral edge of the supported surface 40a faces the supporting surface 12b. In other words, the support surface 12b is bonded to the peripheral edge of the supported surface 40a with the adhesive tape TP, and supports the peripheral edge of the cover panel 40.

The adhesive tape TP is located inside in the X direction and inside in the Y direction from the outer peripheral edge of the support surface 12b. Further, the adhesive tape TP may be integrally formed into a frame shape in a plan view, or may be divided into a plurality of pieces and placed on the support surface 12b.

As shown in FIG. 4, the cover panel 40 before being adhered to the support body 10 has a flat plate shape. The supported surface 40a of the cover panel 40 and the supporting surface 12b of the support body 10 are adhered to each other via the adhesive tape TP, so that the cover panel 40 is curved as described above.

Further, the display panel 30 is attached to the cover panel 40 before being adhered to the support body 10, and the cover panel 40 is in the form of a flat plate without being adhered to the support surface 12b. By bonding the cover panel 40 and the support surface 12b, the display panel 30 is curved together with the cover panel 40. In other words, the display panel 30 is curved convexly toward the -Z side corresponding to the cover panel 40 in a state where the cover panel 40 is adhered to the support surface 12b.

As shown in FIGS. 5 and 6, the display device 1 further includes an adhesive 50. Adhesive 50 is a thermoplastic adhesive. The material of the adhesive 50 is a thermoplastic resin (eg, ethylene vinyl acetate). Therefore, the manufacturing equipment becomes simple and the adhesive 50 is easy to handle. Note that the material of the adhesive 50 may be an ultraviolet curable resin.

The adhesive 50 extends from the recess 12c to the supported surface 40a of the cover panel 40, and bonds the support 10 and the cover panel 40 together. Specifically, the adhesive 50 fills the recess 12c, extends continuously from the periphery of the recess 12c to the outer peripheral edge of the support surface 12b on the outer plate surface 12d of the side wall 12, and It extends continuously to the peripheral edge of the support surface 40a.

The adhesive 50 is located inside in the X direction and inside in the Y direction from the outer peripheral edge of the supported surface 40a. Further, the adhesive 50 is also present between the supporting surface 12b and the supported surface 40a, and adheres the supporting surface 12b and the supported surface 40a. Note that the adhesive 50 does not need to be present between the supporting surface 12b and the supported surface 40a. Further, the adhesive 50 is applied to a position away from the notch 12a, and is not applied to the notch 12a.

Adhesive 50 is applied after support 10 and cover panel 40 are bonded together. The adhesive 50 is applied in a heated and softened state, and spreads from the recess 12c to the supported surface 40a as described above. Thereafter, when the temperature of the adhesive 50 decreases, the adhesive 50 hardens.

As described above, the presence of the recess 12c in the outer plate surface 12d of the side wall 12 increases the contact area between the outer plate surface 12d and the adhesive 50, and increases the adhesive strength between the support body 10 and the cover panel 40. Therefore, the cover panel 40 becomes more difficult to come off from the support body 10.

Further, as described above, the cover panel 40 is in a flat plate shape before being adhered to the support body 10, and is curved in a convex shape toward the support body 10 and adhered to the support body 10. Therefore, an elastic force is generated in the cover panel 40 that is adhered to the support body 10 so as to return it to a flat shape. That is, when the cover panel 40 is curved from a flat plate shape and is adhered to the support body 10, the cover panel 40 is bent from the support body 10, compared to a state where the cover panel 40 is flat and adhered to the support body 10. easily come off. Furthermore, when the cover panel 40 is curved convexly toward the support 10 side, the elastic force generated in the cover panel 40 is greater than when the cover panel 40 is curved convexly toward the side opposite to the support 10. is large, and the cover panel 40 easily comes off from the support body 10.

Therefore, the display device 1 of the first embodiment has the recess 12c in the side wall 12 of the support body 10, as described above. Therefore, the adhesive strength between the support 10 and the cover panel 40 is increased, and even if the cover panel 40 is curved in a convex shape toward the support 10, the cover panel 40 is difficult to come off from the support 10.

Further, since the adhesive 50 is present between the supporting surface 12b and the supported surface 40a and bonds the supporting surface 12b and the supported surface 40a, the adhesive strength is further increased. Therefore, the cover panel 40 is difficult to come off from the support body 10.

The recessed portion 12c is located on the outer plate surface 12d of the side wall 12 and has a groove shape extending along the support surface 12b. Therefore, the recess 12c can be easily formed.

Further, the support surface 12b supports the peripheral edge of the cover panel 40. Furthermore, the adhesive strength is increased by the recessed portion 12c. Therefore, the contact area with the adhesive 50 at the peripheral edge of the cover panel 40 can be reduced. As described above, the recess 12c is located at a position overlapping the support surface 12b when the display device 1 is viewed from the cover panel 40 side. Therefore, in plan view, the area of the frame area FA can be reduced. Specifically, the distance between the display area DA and the peripheral edge of the front surface 1a can be shortened, that is, the width of the frame area FA can be reduced. Therefore, the appearance of the display device 1 can be improved.

<Modified example of the first embodiment>
Next, regarding the display device 1 according to a modification of the first embodiment, mainly the different parts from the display device 1 of the first embodiment described above will be described.

FIG. 7 is a partially enlarged sectional view showing the display device 1 according to the first modification of the first embodiment. The recess 112c of the display device 1 of the first modified example is different from the recess 12c of the display device 1 of the first embodiment described above.

In the recess 112c of the first modification, the +Z side surface is a tapered surface whose width in the Z direction increases from the bottom of the recess 112c toward the open side of the recess 112c. This makes it easier for the adhesive 50 to enter the recess 112c. Note that the −Z side surface of the recess 112c may be a tapered surface such that the width of the recess 112c in the Z direction increases from the bottom of the recess 112c toward the open side of the recess 112c.

Further, in the outer plate surface 12d of the side wall 12, a region between the recess 112c and the back surface of the support body 10 is located on the outer side of the display device 1 than a region 12d1 between the recess 112c and the support surface 12b. You may. This increases the width of the adhesive 50 in the X direction when viewed in cross section on a plane perpendicular to the Z direction. This allows the adhesive 50 to spread more reliably and continuously from the recess 112c to the supported surface 40a.

FIG. 8 is a partially enlarged sectional view showing the display device 1 according to the second modification of the first embodiment. Compared to the display device 1 of the first embodiment described above, the display device 1 of the second modified example has a first slope surface 212b1.

The first sloped surface 212b1 is located at the peripheral edge of the support surface 12b. The first sloped surface 212b1 is a plane (slanted surface) in which the distance from the supported surface 40a increases from inside the peripheral edge of the supporting surface 12b toward the peripheral edge of the supporting surface 12b. The first slope surface 212b1 is formed, for example, by chamfering (specifically, so-called C-chamfering) the +Z side end of the side wall 12. The first slope surface 212b1 may be arranged on the entire peripheral edge of the support surface 12b, or may be arranged on a part of the peripheral edge of the support surface 12b.

By disposing the first slope surface 212b1 on the peripheral edge of the support surface 12b, when the adhesive 50 is applied, the adhesive 50 easily flows between the support surface 12b and the supported surface 40a, and the support The adhesive 50 is more reliably positioned between the surface 12b and the supported surface 40a. Therefore, adhesive strength between the support body 10 and the cover panel 40 can be ensured.

FIG. 9 is a partially enlarged sectional view showing the display device 1 according to the third modification of the first embodiment. Compared to the display device 1 of the first embodiment described above, the display device 1 of the third modified example has a second slope surface 312b1.

The second sloped surface 312b1 is located at the peripheral edge of the support surface 12b. The second slope surface 312b1 is a curved surface in which the distance from the supported surface 40a increases from the inner side of the periphery of the support surface 12b toward the periphery of the support surface 12b. The second slope surface 312b1 is formed, for example, by chamfering (specifically, so-called R chamfering) the +Z side end of the side wall 12. The second slope surface 312b1 may be arranged on the entire peripheral edge of the support surface 12b, or may be arranged on a part of the peripheral edge of the support surface 12b.

By disposing the second sloped surface 312b1 on the peripheral edge of the support surface 12b, when the adhesive 50 is applied, the adhesive 50 easily flows between the support surface 12b and the supported surface 40a, and the support The adhesive 50 is more reliably positioned between the surface 12b and the supported surface 40a. Therefore, adhesive strength between the support body 10 and the cover panel 40 can be ensured.

FIG. 10 is a partially enlarged sectional view showing a display device 1 according to a fourth modification of the first embodiment. Compared to the display device 1 of the first embodiment described above, the display device 1 of the fourth modification has a stepped surface 412b1.

The step surface 412b1 is located at the peripheral edge of the support surface 12b. The stepped surface 412b1 is a plane whose distance from the supported surface 40a is greater than the distance between the supported surface 40a and a portion of the support surface 12b where the adhesive tape TP is disposed. For example, a step surface 412b1 is formed by forming a step on the peripheral edge of the support surface 12b. The stepped surface 412b1 may be arranged on the entire peripheral edge of the support surface 12b, or may be arranged on a part of the peripheral edge of the support surface 12b.

By disposing the step surface 412b1 on the peripheral edge of the support surface 12b, when the adhesive 50 is applied, the adhesive 50 easily flows between the support surface 12b and the supported surface 40a, and the support surface 12b The adhesive 50 is more reliably positioned between the support surface 40a and the supported surface 40a. Therefore, adhesive strength between the support body 10 and the cover panel 40 can be ensured.

<Second embodiment>
Next, regarding the display device 1 according to the second embodiment, mainly the differences from the display device 1 of the first embodiment described above will be explained.

FIG. 11 is a partially enlarged sectional view of the display device 1 according to the second embodiment. Compared to the display device 1 of the first embodiment described above, the display device 1 of the second embodiment does not have the recess 12c. Further, the side wall 12 of the second embodiment has a flange portion 512g at the end on the +Z side.

The flange portion 512g protrudes laterally outward of the display device 1 at the +Z side end of the side wall 12. The flange portion 512g may be formed over the entire circumference of the +Z side end of the side wall 12, or may be formed on a portion thereof. The +Z side surface of the flange portion 512g corresponds to the support surface 512b.

The adhesive 50 is between the supporting surface 512b and the supported surface 40a, and extends from the outer surface of the flange portion 512g to the supported surface 40a. Therefore, in the display device 1 of the second embodiment, the adhesive strength between the support body 10 and the cover panel 40 is increased compared to the case where the adhesive 50 is not present between the support surface 512b and the supported surface 40a. Note that the side wall 12 does not need to have the flange portion 512g.

Further, the peripheral edge of the support surface 512b may include the first sloped surface 212b1 (see FIG. 8), the second sloped surface 312b1 (see FIG. 9), and the stepped surface 412b1 (see FIG. 10). .

Although preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to such embodiments. The contents disclosed in the embodiments are merely examples, and various changes can be made without departing from the spirit of the present disclosure. Appropriate changes made without departing from the spirit of the present disclosure also naturally fall within the technical scope of the present disclosure. At least one of various omissions, substitutions, and modifications of the constituent elements can be made without departing from the gist of each of the embodiments and modifications described above.

For example, the display device 1 has a flat shape that is not curved convexly toward the −Z side when viewed in cross section on a plane orthogonal to the Y direction, and is flat and not curved convexly on the −Z side when viewed in cross section on a plane orthogonal to the X direction. It may be curved. Furthermore, the display device 1 is curved convexly toward the -Z side when viewed in cross section on a plane orthogonal to the Y direction, and curved convexly toward the −Z side when viewed in cross section on a plane orthogonal to the X direction. You can leave it there. In this case, it goes without saying that the support 10, the illumination device 20, the display panel 30, and the cover panel 40 curve in accordance with the curvature of the display device 1.

Further, the display device 1 may be curved in a convex shape toward the +Z side. In this case, the support body 10, the lighting device 20, the display panel 30, and the cover panel 40 are also curved convexly toward the +Z side.

Furthermore, in the first embodiment, the bottom wall 11 of the support body 10 may have a flat plate shape parallel to the X direction and the Y direction without being curved. In this case, the lighting device 20 also has a flat plate shape corresponding to the bottom wall 11.

Further, the display device 1 may be flat without being curved. In this case, the support 10, the lighting device 20, the display panel 30, and the cover panel 40 are also flat.

In addition, other effects brought about by the aspects described in this embodiment that are obvious from the description in this specification or that can be appropriately conceived by those skilled in the art are naturally understood to be brought about by the present disclosure. .
