[0049] The display device of the present utility model is configured as follows. Hereinafter, the same or equivalent constituent elements, components, or processes shown in the respective drawings are denoted by the same reference numerals, and repeated descriptions are appropriately omitted. In addition, for ease of understanding, the dimensions of the respective components in the respective drawings are shown with appropriate enlargement or reduction.

[0050] (First Embodiment)

[0051] Use Figures 1 to 6 The display device 1 of the first embodiment will be described. Figure 1 This is a front view of the display device 1. Figure 2 This is a view of the Figure 1 portion C shown in the display device 1 enlarged. Figure 3 This is a view of the Figure 1 portion D shown in the display device 1 enlarged. Figure 4 This is a rear view of the display device 1. Figure 5 This is a cross-sectional view of the display device 1 taken along the cutting line A-A shown by Figure 4 . Figure 6 This is a cross-sectional view of the display device 1 taken along the cutting line B-B shown by Figure 4 .

[0052] As Figure 1 shown, an orthogonal coordinate system composed of an X-axis, a Y-axis, and a Z-axis is defined. Specifically, the X-axis extends along the depth direction of the display device 1, the Y-axis extends along the width direction of the display device 1, and the Z-axis extends along the height direction of the display device 1. In addition, in this specification, the +X side is sometimes referred to as the front, and the -X side is sometimes referred to as the rear. Furthermore, the -Y side is sometimes referred to as the right side, the +Y side is sometimes referred to as the left side, the +Z side is sometimes referred to as the upper side, and the -Z side is sometimes referred to as the lower side. Also, the surface on the +X side of a component is sometimes referred to as the front surface, and the surface on the -X side of a component is sometimes referred to as the back surface. Sometimes, the portion of a component located at the forefront is referred to as the front end, and the portion of a component located at the rearmost is referred to as the rear end.

[0053] In this specification, expressions such as "parallel" or "perpendicular" also include cases where two elements are not completely parallel or perpendicular. That is, "parallel" or "perpendicular" also includes cases where two elements are substantially parallel or perpendicular, such as cases where they deviate from parallel or perpendicular by about several degrees. In addition, in this specification, the expression "the same" also includes cases where two elements are not completely the same. That is, the expression "the same" also includes cases where two elements are substantially the same, such as cases where they differ by about a few percent.

[0054] The display device 1 includes a cover panel 11, a display panel 12, a frame 14, and a bezel 21 having a first side wall 211 and a second side wall 212. Additionally, the display device 1 may also include a support panel 13, a dimming film 19, and a cable 23. Hereinafter, an example in which the display device 1 includes the support panel 13, the dimming film 19, and the cable 23 will be described.

[0055] The display panel 12 displays an image on the front surface 121. The display panel 12 has a display area DA as an area for displaying an image and a peripheral area PFA as an area for arranging circuits and the like. Additionally, the display panel 12 allows external light incident from the front and the rear to pass through in the display area DA. The display panel 12 is, for example, a transparent OLED (Organic Light Emitting) panel. The display panel 12 may be any transparent display panel as long as it is transparent and does not necessarily have to be a transparent OLED panel. For example, the display panel 12 may also be a transparent LED (Light Emitting Diode) panel or a transparent micro-LED panel with miniaturized LED element sizes. In addition, any transparent display panel of the projection type or the self-emission type can be used. The display device 1 is, for example, arranged between the front seat and the rear seat of a vehicle and is used as a partition and a display in the vehicle.

[0056] The dimming film 19 is disposed on the back side of the display panel 12. The dimming film 19 and the display panel 12 are adhered to each other by an OCA (Optical Clear Adhesive) 18. The dimming film 19 can control the light transmittance. The dimming film 19 can switch between a light-transmitting state and a light-blocking state. When external light is incident from the rear, when observing the image displayed on the display panel 12 from the front, by setting the dimming film 19 to the light-blocking state, the contrast of the image displayed on the display panel 12 can be improved. The dimming film 19, for example, has a liquid crystal material. The transmittance of the dimming film 19 is controlled, for example, by changing the voltage applied to the liquid crystal material.

[0057] The cover panel 11 is located in front of the display panel 12. The cover panel 11 protects the display panel 12 from external forces. Additionally, the cover panel 11 has light-transmitting properties. That is, the cover panel 11 allows the light of the image of the display panel 12 to pass through forward. In addition, the cover panel 11 allows external light incident from the front and the rear to pass through. The cover panel 11 and the display panel 12 are adhered to each other by an OCA 17. The cover panel 11 is formed of glass, for example. Thereby, the cover panel 11 can be made less vulnerable to damage.

[0058] The cover panel 11 has a first area corresponding to the display area DA and a second area corresponding to the peripheral area. Figure 1In [the figure], the boundary between the first region and the second region is indicated by a single dotted line. The first region is the region inside the single dotted line, and the second region is the region outside the single dotted line. The second region covering the front surface or the back surface of the cover panel 11 may also be colored. For example, black printing may be performed on the second region of the front surface or the back surface of the cover panel 11. Additionally, for example, a black tape may be pasted on the second region of the front surface or the back surface of the cover panel 11. By configuring it in this way, it is possible to make the components located behind the second region less visible from the front. Thereby, the aesthetic appearance of the display device 1 can be improved. Here, the components located behind the second region are, for example, circuits and the like arranged in the peripheral region PFA in the display panel 12.

[0059] The support panel 13 is located behind the light control film 19. The support panel 13 and the light control film 19 are adhered to each other using the OCA 20. The support panel 13 protects the light control film from external forces. Additionally, the support panel 13 has light transmissivity and allows external light incident from the front and the back to pass through. The support panel 13 is formed of glass, for example. Thereby, it is possible to make the support panel 13 less likely to be damaged.

[0060] The cover panel 11 and the support panel 13 may not be formed of glass but may be formed of resin, for example. By forming the cover panel 11 and the support panel 13 of resin, it is lighter compared to the case of being formed of glass.

[0061] Additionally, other adhesives having light transmissivity may be used instead of the OCA 17, OCA 18, and OCA 20. For example, OCR (Optical Clear Resin) may be used instead of the OCA.

[0062] The frame 14 supports the cover panel 11, the display panel 12, the dimming film 19, and the support panel 13. The frame 14 has a frame shape when viewed from the front. The frame 14 has a first front surface 141, a second front surface 142, a first connection surface 143, a back surface 144, a side surface 145, and a second connection surface 146. The first front surface 141 is located in a position more forward than the second front surface 142. The first front surface 141 is parallel to the back surface of the cover panel 11. In addition, the second front surface 142 is parallel to the back surface of the support panel 13. The first connection surface 143 connects the first front surface 141 and the second front surface 142. The first connection surface 143 extends so as to surround the side surfaces of the display panel 12, the dimming film 19, and the support panel 13 over the entire circumference. The back surface 144 is parallel to the first front surface 141 and the second front surface 142. In addition, the side surface 145 is perpendicular to the front surface of the display panel 12, the first front surface 141, and the back surface 144. The second connection surface 146 connects the second front surface 142 and the back surface 144. When the display device 1 is viewed from the front, the second connection surface 146 is located in a position outside the display area DA. More specifically, when the display device 1 is viewed from the front, the second connection surface 146 extends outside the display area DA so as to surround the entire circumference of the display area DA. The second connection surface 146 is the inner side surface of the frame 14 having a frame shape. Thus, external light incident on the display area DA from the front and rear of the display device 1 is not blocked by the frame 14.

[0063] The frame 14 and the cover panel 11 are adhered to each other using a double-sided tape 15. More specifically, the first front surface 141 and the back surface of the cover panel 11 are adhered to each other using the double-sided tape 15. In addition, the frame 14 and the support panel 13 are adhered to each other using a double-sided tape 16. More specifically, the second front surface 142 and the back surface of the support panel 13 are adhered to each other using the double-sided tape 16. The frame 14 is formed of a metal material having high rigidity, such as aluminum alloy or magnesium alloy, for example.

[0064] The frame 21 is connected to the frame 14. The frame 21 has a first side wall 211 and a second side wall 212. The frame 21 may also have a connecting member 213, a rear wall 214, and a front wall 215. Hereinafter, an example in which the frame 21 has a connecting member 213, a rear wall 214, and a front wall 215 will be described. The frame 21 is formed of, for example, a galvanized steel sheet or stainless steel. In addition, in the present embodiment, the first side wall 211, the second side wall 212, the connecting member 213, the rear wall 214, and the front wall 215 are formed of, for example, metal plates having the same thickness. That is, when viewed from the Z direction, the first side wall 211, the second side wall 212, the connecting member 213, the rear wall 214, and the front wall 215 have, for example, the same thickness. The frame 21 can reduce damage to the display device 1 caused by external forces. In addition, in this specification, the expression "reduce damage" for a member also includes the case of reducing the possibility of the member being damaged.

[0065] The first side wall 211 surrounds the side surface 145. More specifically, the first side wall 211 has a frame shape so as to surround the entire circumference of the side surface 145. The first side wall 211 has a first portion 2113, a second portion 2114, a third portion 2115, and a fourth portion 2116. The first portion 2113 and the second portion 2114 extend in the Z direction when viewed from the front. The first portion 2113 is located on the right side of the frame 14. The second portion 2114 is located on the left side of the frame 14. In addition, the third portion 2115 extends in the Y direction when viewed from the front. The third portion 2115 is located on the upper side of the frame 14. The fourth portion 2116 is located on the lower side of the frame 14. The first side wall 211 has a first surface 2111 and a second surface 2112 located on the side opposite to the side where the first surface 2111 is located. The first surface 2111 faces the side surface 145. The first surface 2111 and the side surface 145 may be in contact with each other. In the present embodiment, the first surface 2111 extends in the +X direction to a position opposite to the side surface of the cover panel 11. That is, when viewed from the normal direction of the side surface 145, the first side wall 211 overlaps with the cover panel 11. On the other hand, the cover panel 11 is disposed at an interval from the first side wall 211. That is, the first surface 2111 does not contact the side surface of the cover panel 11. Thus, for example, when an external force caused by a side collision is transmitted to the first side wall 211, it is possible to make it difficult for the external force to be transmitted to the cover panel 11. Therefore, damage to the cover panel 11 can be reduced.

[0066] The second side wall 212 is located on the side opposite to the side where the frame 14 is located with respect to the first side wall 211, and is arranged at an interval from the first side wall 211. The first part 2113 and the second part 2114 are parallel to the second side wall 212. The second side wall 212 extends in the Z direction along the first part 2113 and the second part 2114. The second side wall 212 is located outside at least one of the first part 2113 and the second part 2114. In the present embodiment, the second side wall 212 is respectively located outside the first part 2113 and the second part 2114.

[0067] The connecting member 213 connects the first side wall 211 and the second side wall 212. The connecting member 213 has a third surface 2131 that intersects the second surface 2112. In the present embodiment, the third surface 2131 faces forward. The connecting member 213 may also be integrally formed with the first side wall 211 or the second side wall 212. In the present embodiment, the connecting member 213 and the second side wall 212 are integrally formed of the same material, for example.

[0068] By including the frame 21 having the first side wall 211 and the second side wall 212, the display device 1 can reduce damage to the display device 1 caused by external forces. First, consider the case where an external force is applied to the display device 1 from the right or left direction. The external force applied to the display device 1 from the right or left direction is, for example, an external force caused by a side collision of a vehicle. In this case, the external force is first applied to the second side wall 212. Since the second side wall 212 is arranged at an interval from the first side wall 211, the second side wall 212 can fall toward the first side wall 211. At this time, a part of the external force applied to the second side wall 212 is consumed as the energy for the second side wall 212 to fall. Therefore, the external force transmitted from the second side wall 212 to the first side wall 211 via the connecting member 213 can be reduced. As a result, damage to the first side wall 211 can be reduced. By reducing damage to the first side wall 211, damage to the members located on the side opposite to the side where the second side wall 212 is located with respect to the first side wall 211 can be reduced. Here, the members located on the side opposite to the side where the second side wall 212 is located with respect to the first side wall 211 are, for example, the cover panel 11, the display panel 12, the dimming film 19, and the support panel 13.

[0069] When viewed from the normal direction of the side surface 145, the front end of the connecting member 213 overlaps with the front end of the frame 14 or is located behind the front end of the frame 14. In the present embodiment, the front end of the connecting member 213 refers to the third surface 2131. In addition, the front end of the frame 14 refers to the first front surface 141. With such a configuration, the external force transmitted in the order of the second side wall 212, the connecting member 213, and the first side wall 211 can be easily transmitted from the first side wall 211 to the frame 14 and is not easily transmitted to the cover panel 11. For example, when viewed from the normal direction of the side surface 145, if the front end of the connecting member 213 is located in front of the front end of the frame 14, the external force from the first side wall 211 may be transmitted not only to the frame 14 but also to the cover panel 11. On the other hand, by configuring the front end of the connecting member 213 to overlap with the front end of the frame 14 or be located behind the front end of the frame 14, the external force can be easily transmitted from the first side wall 211 to the frame 14 and is not easily transmitted to the cover panel 11. By making the external force not easily transmitted to the cover panel 11, damage to the cover panel 11 can be reduced. In the present embodiment, the front end of the connecting member 213 is located behind the front end of the frame 14. The farther the connecting member 213 is connected to the first side wall 211 away from the cover panel 11, the less likely the external force is to be transmitted to the cover panel 11. Therefore, the connecting member 213 is preferably connected to the rear end of the first side wall 211.

[0070] The rear wall 214 is connected to the frame 14. More specifically, the rear wall 214 is fixed to the frame 14 by screws 22. In the present embodiment, two rear walls 214 are provided on each of the left and right sides of the display device 1, for a total of 4, which are respectively connected to the frame 14. In addition, one rear wall 214 is fixed to the frame 14 by two screws 22. In addition, the number of the rear walls 214 and the number of the screws 22 are not limited thereto. For example, one rear wall 214 may be provided on each of the left and right sides, or three or more may be provided on each of the left and right sides. In addition, one rear wall 214 may be fixed to the frame 14 by one screw 22 or may be fixed to the frame 14 by three or more screws 22. The rear wall 214 is connected to the first side wall 211. As Figure 4 、 Figure 5 and Figure 6 shown, the rear wall 214 of the present embodiment is formed by folding back a part of the connecting member 213 toward the frame 14 in contact with the back surface 144. Therefore, as Figure 4 shown, the connecting member 213 has a notch 2132. In the present embodiment, the connecting member 213 has 4 notches 2132. With such a configuration, the weight reduction of the display device 1 can be achieved.

[0071] The external force applied to the frame 21 is easily transmitted to the frame 14 via the connection portion between the frame 21 and the frame 14. Therefore, the farther the connection portion between the frame 21 and the frame 14 is from the cover panel 11, the more the external force transmitted to the cover panel 11 can be reduced. Therefore, by connecting the rear wall 214 located at a position far from the cover panel 11 to the frame 14, the external force transmitted to the cover panel 11 can be reduced.

[0072] The front wall 215 is located in front of the cover panel 11. The front wall 215 extends along the front surface of the cover panel 11. The front wall 215 is connected to the first side wall 211. The front wall 215 is arranged at an interval from the cover panel 11. That is, the back surface of the front wall 215 does not contact the front surface of the cover panel 11. Thus, even if the external force applied to the second side wall 212 is transmitted to the front wall 215 via the first side wall 211, the external force is not easily transmitted from the front wall 215 to the cover panel 11. In addition, the front wall 215 can prevent the cover panel 11 from falling off to a position in front of the front wall 215.

[0073] The cable 23 is electrically connected to the display panel 12. The cable 23 transmits the signal for driving the display panel 12 to the display panel 12. One end of the cable 23 is electrically connected to the display panel 12, and the other end is connected to a driving device (not shown). The driving device generates a driving signal for driving the display panel. The driving signal generated by the driving device is transmitted to the display elements included in the display panel 12 via the cable 23 and the driver IC included in the display panel 12. The light emission of the display elements is controlled by the driving signal. The cable 23 is located between the first side wall 211 and the second side wall 212. In the present embodiment, three cables 23 are respectively arranged between the first side wall 211 and the second side wall 212 on the right side of the display device 1 and between the first side wall 211 and the second side wall 212 on the left side of the display device 1. In addition, the number of the cables 23 is not limited thereto. For example, one or two cables 23 may be respectively arranged on the right side and the left side of the display device, or four or more cables 23 may be respectively arranged. By arranging the cable 23 between the first side wall 211 and the second side wall 212, a part of the external force applied to the second side wall 212 can be absorbed by the cable 23. Therefore, the external force can be reduced without using a buffer member separately.

[0074] As described above, the display device 1 of the present embodiment includes a display panel 12, a cover panel 11, a frame 14, and a border 21. The display panel 12 displays an image on the front surface 121. The cover panel 11 is located in front of the display panel 12 and has translucency. The frame 14 supports the display panel 12 and the cover panel 11. The border 21 is connected to the frame 14. The frame 14 has a side surface 145 perpendicular to the front surface 121, and the border 21 has a first side wall 211 surrounding the side surface 145 and a second side wall disposed on the side opposite to the side where the frame 14 is located with respect to the first side wall 211 and spaced apart from the first side wall 211.

[0075] With such a configuration, the display device 1 of the present embodiment can reduce damage to the display device 1 caused by external forces.

[0076] (Second Embodiment)

[0077] Hereinafter, a second embodiment of the display device of the present disclosure will be described with reference to the drawings.

[0078] The display device 1a of the present embodiment includes a second side wall 212a instead of the second side wall 212 in the first embodiment. Regarding other structures, since they are the same as those of the display device 1 in the first embodiment, the same reference numerals are given to the constituent elements that are the same as those of the display device 1 in the first embodiment, and the description thereof is omitted.

[0079] In addition, in the following embodiments, for the sake of simplifying the drawings, the OCA 18, OCA 20, dimming film 19, screws 22, and cables 23 in the first embodiment may be appropriately omitted sometimes.

[0080] Figure 7 is a schematic cross-sectional view of the display device 1a cut at the same position as the cutting line B-B shown in Figure 4 the figure.

[0081] The second side wall 212a is configured in the same manner as the second side wall 212, except for the thickness in the normal direction of the first surface 2111. The thickness of the second side wall 212a in the normal direction of the first surface 2111 is larger than the thickness of the connecting member 213 in the normal direction of the third surface 2131. Specifically, the thickness of the second side wall 212a in the normal direction of the first surface 2111 is approximately twice the thickness of the connecting member 213 in the normal direction of the third surface 2131. The second side wall 212a is formed, for example, as follows. First, a side wall is provided such that the length in the +X direction is approximately twice the X-direction length of the first side wall 211 and has, for example, the same thickness as the connecting member 213. Then, this side wall is folded from the +X direction toward the -X direction so that the length in the X direction becomes approximately half. By configuring it in this way, the thickness of the second side wall 212a increases, and thus the strength against external forces can be improved. In addition, when an external force is applied to the second side wall 212a, since the energy consumed by the second side wall 212a falling toward the first side wall 211 increases, the external force transmitted from the second side wall 212a to the first side wall 2111 can be further reduced.

[0082] In the present embodiment, the thickness of the second side wall 212a is approximately twice the thickness of the connecting member 213, but the thickness of the second side wall 212a may also be greater than approximately twice the thickness of the connecting member 213. For example, the thickness of the second side wall 212a may also be approximately three times the thickness of the connecting member 213. In addition, for the second side wall 212a, as long as the thickness in the normal direction of the first surface 2111 can be increased, it does not have to be formed as a fold. For example, the second side wall 212a may also be cast so that the thickness in the normal direction of the first surface 2111 is large.

[0083] The display device 1a of the present embodiment includes a first buffer member 24, a second buffer member 25, and a protective film 26. In addition, the display devices in the embodiments other than the present embodiment described in this specification may also include the first buffer member 24, the second buffer member 25, and the protective film 26. In addition, the display device may include all three of the first buffer member 24, the second buffer member 25, and the protective film 26, or may include only any one or any two of the three.

[0084] The first buffer member 24 is located between the side surface 145 and the first surface 2111. The first buffer member 24 is, for example, a rubber material. The first buffer member 24 absorbs a part of the external force transmitted from the first side wall 211 to the frame 14. When the external force applied to the second side wall 212a is sequentially transmitted to the connecting member 213, the first side wall 211, and then to the frame 14, a part of this external force can be absorbed by the first buffer member 24. Therefore, the external force transmitted to the frame 14 can be reduced, and thus the damage to the frame 14 can be reduced.

[0085] The second buffer member 25 is located between the back surface of the front wall 215 and the front surface of the covering panel 11. The second buffer member 25 is, for example, made of a rubber material. The second buffer member 25 absorbs a part of the external force transmitted from the front wall 215 to the covering panel 11. When the external force transmitted to the second side wall 212a is sequentially transmitted to the connecting member 213, the first side wall 211, the front wall 215, and then to the covering panel 11, a part of the external force can be absorbed by the second buffer member 25. Thereby, the external force transmitted to the covering panel 11 can be reduced, and thus the damage to the covering panel 11 can be reduced.

[0086] The protective film 26 covers the outer surfaces of the covering panel 11 and the frame 14. The protective film 26 protects the covering panel 11 and the frame 14. Since the protective film 26 can protect the covering panel 11 and the frame 14 from external forces, the damage to the covering panel 11 and the frame 14 can be reduced. The protective film 26 is formed of a resin. The protective film 26 is formed of, for example, PET (Polyethylene Terephthalate) resin, PP (Polypropylene) resin, or PVC (Polyvinyl Chloride) resin.

[0087] (Third Embodiment)

[0088] Hereinafter, a third embodiment of the display device of the present disclosure will be described with reference to the drawings.

[0089] The display device 1b of the present embodiment includes a first side wall 211b instead of the first side wall 211 of the first embodiment. In addition, the display device 1b does not include the front wall 215. Regarding other structures, since they are the same as those of the display device 1 of the first embodiment, the same reference numerals are assigned to the same constituent elements as those of the display device 1 of the first embodiment, and the description thereof is omitted.

[0090] Figure 8 is a schematic cross-sectional view of the display device 1b cut at the same position as the cutting line B - B shown in Figure 4 the figure.

[0091] The first side wall 211b is formed in the same manner as the first side wall 211, except for the thickness in the normal direction of the first surface 211b. The thickness of the first side wall 211b in the normal direction of the first surface 2111b is larger than the thickness of the connecting member 213 in the normal direction of the third surface 2131. Specifically, the thickness of the first side wall 211b in the normal direction of the first surface 2111b is approximately twice the thickness of the connecting member 213 in the normal direction of the third surface 2131. The first side wall 211b is formed, for example, as follows. First, a side wall is provided such that its length in the +X direction is approximately twice the X-direction length of the second side wall 212 and has the same thickness as the connecting member 213. Then, this side wall is folded from the +X direction to the -X direction so that its X-direction length becomes approximately half. By configuring in this way, the thickness of the first side wall 211b increases, and thus the strength against external forces can be improved. Therefore, damage to the first side wall 211b can be reduced.

[0092] In the present embodiment, the thickness of the first side wall 211b is approximately twice the thickness of the connecting member 213, but the thickness of the first side wall 211b may also be greater than approximately twice the thickness of the connecting member 213. For example, the thickness of the first side wall 211b may be approximately three times the thickness of the connecting member 213. In addition, for the first side wall 211b, as long as the thickness in the normal direction of the first surface 2111b can be increased, it does not have to be formed by folding. For example, the first side wall 211b may be cast to have a larger thickness in the normal direction of the first surface 2111b.

[0093] In addition, the display device 1b does not include the front wall 215. The display devices in the embodiments other than the present embodiment described in this specification may also not include the front wall 215. By not providing the front wall 215, the aesthetic appearance of the display device 1b when viewed from the front can be improved.

[0094] When the display device does not have the front wall 215, as Figure 8 shown, the length of the second side wall 212 in the +X direction is preferably such that when the second side wall 212 falls toward the first side wall 211 side, it can contact the first side wall 211 but not contact the cover panel 11. Specifically, it is preferably that when viewed from the normal direction of the side surface 145, the front end of the second side wall 212 overlaps the back surface of the cover panel 11 or is located at a position behind the back surface of the cover panel 11. By configuring in this way, even when an external force is applied to the second side wall 212 and the second side wall 212 falls toward the first side wall 211a side, it is possible to make the second side wall 212 less likely to contact the cover panel 11. Therefore, the possibility that the external force applied to the second side wall 212 is directly transmitted to the cover panel 11 can be reduced. Therefore, damage to the cover panel 11 can be reduced.

[0095] (Fourth Embodiment)

[0096] Hereinafter, a fourth embodiment of the display device of the present disclosure will be described with reference to the accompanying drawings.

[0097] The display device 1c of the present embodiment includes a first side wall 211c instead of the first side wall 211 of the first embodiment. In addition, the display device 1c includes a third side wall 216. Further, the display device 1c does not include a front wall 215. Regarding other structures, since they are the same as those of the display device 1 of the first embodiment, the same reference numerals are assigned to the constituent elements that are the same as those of the display device 1 of the first embodiment, and their descriptions are omitted.

[0098] Figure 9 is a schematic cross-sectional view of the display device 1c cut at the same position as the cutting line B-B shown in Figure 4 the figure.

[0099] The first side wall 211c is configured in the same manner as the first side wall 211 except for the length in the X direction. The first side wall 211c extends in the +X direction to the same position as the first front surface 141. That is, when viewed from the normal direction of the side surface 145, the front end of the first side wall 211c overlaps with the first front surface 141.

[0100] The third side wall 216 is connected to the first side wall 211c. More specifically, the third side wall 216 is connected to the front end of the first side wall 211c. The third side wall 216 extends from the first side wall 211c in a direction away from the side surface of the cover panel 11. That is, the third side wall extends obliquely forward from the front end of the first side wall 211c. By configuring in this way, when an external force is applied to the second side wall 212 and the second side wall 212 falls toward the first side wall 211 side, the second side wall 212 can contact the third side wall 216, for example. At this time, the position where the second side wall 212 contacts the third side wall 216 is far from the cover panel 11, so the external force transmitted from the second side wall 212 to the third side wall 216 is not easily transmitted to the cover panel 11. The external force is transmitted from the second side wall 212 to the third side wall 216 at the position where the second side wall 212 contacts the third side wall 216, and then is easily transmitted to the frame 14 via the first side wall 211 and the rear wall 214. Therefore, the possibility that the external force applied to the second side wall 212 is transmitted from the second side wall 212 to the cover panel 11 can be reduced. Therefore, damage to the cover panel 11 can be reduced.

[0101] (Fifth Embodiment)

[0102] Hereinafter, a fifth embodiment of the display device of the present disclosure will be described with reference to the accompanying drawings.

[0103] The display device 1d of the present embodiment has a structure in which the display device 1c of the fourth embodiment further includes a front wall 215 and a fourth side wall 217. Regarding other structures, since they are the same as those of the display device 1c of the fourth embodiment, the same reference numerals are assigned to the constituent elements that are the same as those of the display device 1c of the fourth embodiment, and their descriptions are omitted.

[0104] Figure 10 is a schematic cross-sectional view of the display device 1d cut at the same position as the cutting line B-B shown in Figure 4 the figure.

[0105] The fourth side wall 217 connects the front wall 215 and the third side wall 216. In other words, the front wall 215 is connected to the third side wall 213 via the fourth side wall 217. When viewed from the Z direction, the fourth side wall 217 is parallel to the first side wall 211c. That is, the fourth side wall 217 extends in the X direction parallel to the first side wall 211c. When an external force is applied to the second side wall 212 and the second side wall 212 falls toward the first side wall 211 side, the second side wall 212 can come into contact with the fourth side wall 217, for example. At this time, the position where the second side wall 212 contacts the fourth side wall 217 is far from the cover panel 11, so the external force transmitted from the second side wall 212 to the fourth side wall 217 is not easily transmitted to the cover panel 11. The external force is transmitted from the second side wall 212 to the fourth side wall 217 at the position where the second side wall 212 contacts the fourth side wall 217, and then is easily transmitted to the frame 14 via the first side wall 211c and the rear wall 214. Therefore, damage to the cover panel 11 can be reduced. In addition, the front wall 215 can prevent the cover panel 11 from falling off to a position in front of the front wall 215.

[0106] (Sixth Embodiment)

[0107] Hereinafter, a sixth embodiment of the display device of the present disclosure will be described with reference to the drawings.

[0108] The display device 1e of the present embodiment includes a second side wall 212e in place of the second side wall 212 of the first embodiment. Regarding other structures, since they are the same as those of the display device 1 of the first embodiment, the same reference numerals are assigned to the constituent elements that are the same as those of the display device 1 of the first embodiment, and their descriptions are omitted.

[0109] Figure 11 is a schematic cross-sectional view of the display device 1e cut at the same position as the cutting line B-B shown in Figure 4 the figure.

[0110] The second side wall 212e is configured in the same manner as the second side wall 212, except that it has a curved shape. The second side wall 212e is curved so as to protrude in a direction away from the frame 14. That is, when viewed from the Z direction, the second side wall 212e has a shape that arcs so as to protrude to the outside of the display device 1. The second side wall 212e has a fourth surface 2121 and a fifth surface 2122. The fourth surface 2121 is a surface facing the outside in the left-right direction of the display device 1. The fifth surface 2122 is a surface that intersects the fourth surface 2121 and faces the second surface 2112. When an external force is applied to the second side wall 212e and the second side wall 212e is poured toward the first side wall 211, the front end of the second side wall 212e can contact the first side wall. At this time, the external force applied to the second side wall 212e is dispersed to the front end of the second side wall 212e and the two locations where the second side wall 212e and the connecting member 213 are located. Thus, the external force applied to the second side wall 212e is dispersed and then transmitted to the first side wall 211. Therefore, damage to the first side wall 211, the frame 14 that will transmit the external force via the first side wall 211, and the cover panel 11 can be reduced. Here, the front end of the second side wall 212e refers to the common edge of the fourth surface 2121 and the fifth surface 2122. In addition, the front end of the frame 14 refers to the first front surface 141.

[0111] In addition, when viewed from the normal direction of the side surface 145, the front end of the second side wall 212e overlaps with the front end of the frame 14 or is located behind the front end of the frame 14. By configuring it in this way, the front end of the second side wall 212e contacts the first side wall 211 at a position behind the front end of the frame 14. Thus, the external force can be easily transmitted to the frame 14 and is not easily transmitted to the cover panel 11. For example, when the front end of the second side wall 212e contacts the first side wall 211 at a position in front of the front end of the frame 14, the external force directly transmitted from the second side wall 212e to the first side wall 211 may be transmitted not only to the frame 14 but also to the cover panel 11. On the other hand, by configuring the front end of the second side wall 212e to contact the first side wall 211 at a position behind the front end of the frame 14, the external force directly transmitted from the second side wall 212e to the first side wall 211 can be easily transmitted from the first side wall 211 to the frame 14 and is not easily transmitted to the cover panel 11. By making the external force not easily transmitted to the cover panel 11, damage to the cover panel 11 can be reduced. In the present embodiment, the front end of the second side wall 212e is located behind the front end of the frame 14. The farther the position where the second side wall 212e contacts the first side wall 211 is from the cover panel 11, the less easily the external force is transmitted to the cover panel 11. Therefore, by making the front end of the second side wall 212e located behind the front end of the frame 14, the external force transmitted to the cover panel 11 can be reduced.

[0112] (Seventh Embodiment)

[0113] Hereinafter, a seventh embodiment of the display device of the present disclosure will be described with reference to the accompanying drawings.

[0114] The display device 1f of the present embodiment includes a frame 14f instead of the frame 14 of the first embodiment. In addition, the display device 1f includes a rear wall 214f instead of the rear wall 214. Regarding other structures, since they are the same as those of the display device 1 of the first embodiment, the same reference numerals are given to the constituent elements that are the same as those of the display device 1 of the first embodiment, and their description is omitted.

[0115] Figure 12 is a schematic cross-sectional view of the display device 1f cut at the same position as the cutting line A-A shown in Figure 4 the figure.

[0116] The frame 14f is configured in the same manner as the frame 14 except that the corner portions are cut off. The frame 14f has a first front surface 141, a second front surface 142, a first connection surface 143, a back surface 144, a side surface 145, a second connection surface 146, and an inclined surface 147. The inclined surface 147 extends in a direction intersecting the side surface 145. In addition, the inclined surface 147 is located behind the side surface 145. The inclined surface 147 connects the side surface 145 and the back surface 144. The frame 14f is formed by cutting off the corner portion formed by the back surface 144 and the side surface 145 of the frame 14. By configuring in this way, miniaturization of the frame 14f can be achieved.

[0117] The rear wall 214f is configured in the same manner as the rear wall 214 except that it has a first rear wall 2141 and a second rear wall 2142. The rear wall 214f is connected to the frame 14f. More specifically, the rear wall 214f is fixed to the frame 14f by screws 22. The rear wall 214f has a first rear wall 2141 and a second rear wall 2142. The first rear wall 2141 faces the inclined surface 147 and extends along the inclined surface 147. In this way, by arranging the first rear wall 2141 along the outer shape of the frame 14f, miniaturization of the rear wall 214f can be achieved.

[0118] The second rear wall 2142 faces the back surface 144 and extends along the back surface 144. The second rear wall 2142 is connected to the frame 14f. More specifically, the second rear wall 2142 is fixed to the frame 14f by screws 22. The external force applied to the frame 21f is easily transmitted to the frame 14f via the connection portion between the frame 21f and the frame 14f. Therefore, the farther the connection portion between the frame 21f and the frame 14f is from the cover panel 11, the more the external force transmitted to the cover panel 11 can be reduced. Therefore, by connecting the second rear wall 2142 located at a position far from the cover panel 11 to the frame 14f, the external force transmitted to the cover panel 11 can be reduced.

[0119] As described above, each embodiment of the present disclosure has been described. However, the above-described embodiments are presented as examples and are not intended to limit the scope of the utility model. These new embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the utility model. These new embodiments and their modifications are included in the scope and gist of the utility model and are included in the technical solutions described in the claims and their equivalents. Moreover, the constituent elements of different embodiments and modification examples can be appropriately combined.

[0120] In addition, the effects in each embodiment described in this specification are merely illustrative and are not limited thereto, and other effects may also be provided.

[0121] (Supplementary Note)

[0122] One aspect of the present disclosure is as follows.

[0123] [Item 1] A display device, wherein the display device includes: a display panel that displays an image on a front surface; a cover panel that is located in front of the display panel and has translucency; a frame that supports the display panel and the cover panel; and a border that is connected to the frame, the frame having a side surface perpendicular to the front surface, the border having: a first side wall that surrounds the side surface; and a second side wall that is located on a side opposite to the side where the frame is located with respect to the first side wall and is disposed at an interval from the first side wall.

[0124] According to this aspect, since the second side wall is disposed at an interval from the first side wall, when an external force is applied to the second side wall, the second side wall can fall toward the first side wall. At this time, a part of the external force applied to the second side wall is consumed as energy for the second side wall to fall, and thus the external force transmitted to the first side wall can be reduced accordingly.

[0125] [Item 2] The display device according to Item 1, wherein the border has a connecting member that connects the first side wall and the second side wall, and when viewed from the normal direction of the side surface, the front end of the connecting member overlaps the front end of the frame or is located at a position behind the front end of the frame.

[0126] According to this aspect, the external force transmitted in the order of the second side wall, the connecting member, and the first side wall can be easily transmitted from the first side wall to the frame and is not easily transmitted to the cover panel. For example, when viewed from the normal direction of the side surface of the frame, compared with the case where the front end of the connecting member is located in front of the front end of the frame, the external force is easily transmitted from the first side wall to the frame and is not easily transmitted to the cover panel. By making the external force not easily transmitted to the cover panel, damage to the cover panel can be reduced.

[0127] [Item 3] The display device according to Item 2, wherein the first side wall has a first surface opposite to the side surface and a second surface located on the side opposite to the side where the first surface is located, the connecting member has a third surface intersecting the second surface, and the thickness of the first side wall in the normal direction of the first surface is greater than the thickness of the connecting member in the normal direction of the third surface.

[0128] According to this method, since the thickness of the first side wall becomes larger, the strength against external forces can be improved, and the damage to the first side wall can be reduced. By reducing the damage to the first side wall, the damage to each component located on the side opposite to the side where the second side wall is located with respect to the first side wall and the possibility of each component falling off can be reduced.

[0129] [Item 4] The display device according to Item 2 or 3, wherein the first side wall has a first surface opposite to the side surface and a second surface located on the side opposite to the side where the first surface is located, the connecting member has a third surface intersecting the second surface, and the thickness of the second side wall in the normal direction of the first surface is greater than the thickness of the connecting member in the normal direction of the third surface.

[0130] According to this method, since the thickness of the second side wall becomes larger, the strength against external forces can be improved. Thus, when an external force is applied to the second side wall, the energy consumed due to the second side wall falling over becomes larger, and therefore, the external force transmitted to the first side wall can be further reduced.

[0131] [Item 5] The display device according to any one of Items 1 to 4, wherein the second side wall is bent so as to protrude in a direction away from the frame.

[0132] According to this method, when an external force is applied to the second side wall, the second side wall falls over toward the first side wall, and the front end of the second side wall contacts the first side wall. Therefore, the external force applied to the second side wall is dispersed to two places, namely, the front end of the second side wall and the connection portion between the second side wall and the connecting member. Thus, the external force applied to the second side wall is transmitted to the first side wall after being dispersed, and therefore, the damage to the first side wall, the frame, and the cover panel that will be transmitted the external force via the first side wall can be reduced.

[0133] [Item 6] The display device according to Item 5, wherein when viewed from the normal direction of the side surface, the front end of the second side wall overlaps the front end of the frame or is located behind the front end of the frame.

[0134] According to this method, when an external force is applied to the second side wall, the front end of the second side wall contacts the first side wall at a position behind the front end of the frame. Thus, the external force can be easily transmitted to the frame and is not easily transmitted to the cover panel.

[0135] [Item 7] The display device according to any one of Items 1 to 6, wherein the frame has a rear wall connected to the first side wall, and the rear wall is connected to the frame.

[0136] The external force applied to the second side wall is easily transmitted to the frame via the connection portion between the frame and the frame. At this time, the farther the connection portion between the frame and the frame is from the cover panel, the more the external force transmitted to the cover panel can be reduced. Therefore, according to this method, by connecting the rear wall located at a position far from the cover panel to the frame, the impact transmitted to the cover panel can be reduced.

[0137] [Item 8] The display device according to Item 7, wherein the frame has an inclined surface extending in a direction intersecting the side surface and located behind the side surface, and the rear wall has a first rear wall connected to the first side wall and opposite to the inclined surface.

[0138] According to this method, by forming the frame in a way that cuts off the corner portion, miniaturization of the frame can be achieved. In addition, by forming the rear wall along the outer shape of the frame, miniaturization of the rear wall can be achieved.

[0139] [Item 9] The display device according to Item 8, wherein the frame has a back surface perpendicular to the side surface and connected to the inclined surface, the rear wall has a second rear wall connected to the first rear wall and opposite to the back surface, and the second rear wall is connected to the frame.

[0140] According to this method, by providing the second rear wall and connecting the second rear wall to the frame, the connection portion between the frame and the frame is far from the cover panel, so the external force transmitted to the cover panel can be reduced.

[0141] [Item 10] The display device according to any one of Items 1 to 9, wherein the display device includes a cable, the cable is electrically connected to the display panel, transmits a signal for driving the display panel to the display panel, and the cable is located between the first side wall and the second side wall.

[0142] According to this method, the cable electrically connected to the display panel is used to absorb the external force applied to the second side wall, so that the external force can be reduced without preparing an additional buffer member.

[0143] [Item 11] The display device according to any one of Items 1 to 10, wherein the frame has a front wall connected to the first side wall, and the front wall extends along the front surface of the cover panel.

[0144] According to this method, by providing the front wall, for example, when an external force is transmitted to the covering panel, it is possible to prevent the covering panel from detaching to a position in front of the front wall.

[0145] [Item 12] The display device according to any one of Items 1 to 10, wherein the frame has a third side wall connected to the first side wall, and the third side wall extends from the first side wall in a direction away from the side surface of the covering panel.

[0146] According to this method, when an external force is applied to the second side wall and the second side wall falls toward the first side wall, for example, the second side wall comes into contact with the third side wall. At this time, the position where the second side wall contacts the third side wall is away from the covering panel, so that the external force transmitted to the covering panel can be reduced.

[0147] [Item 13] The display device according to Item 12, wherein the frame has a front wall connected to the third side wall, and the front wall extends along the front surface of the covering panel.

[0148] According to this method, by providing the front wall, for example, when an external force is transmitted to the covering panel, it is possible to prevent the covering panel from detaching to a position in front of the front wall.
