[0008] The display device according to the present disclosure is configured as follows. Hereinafter, identical or equivalent components, members, or steps shown in each drawing will be given the same reference numerals, and duplicated explanations will be omitted as appropriate. In addition, the dimensions of each member in each drawing are enlarged or reduced as appropriate for ease of understanding.

[0009] (First embodiment) The display device 1 of the first embodiment will be described with reference to Figs. 1 to 6. Fig. 1 is a front view of the display device 1. Fig. 2 is an enlarged view of a portion C of the display device 1 shown in Fig. 1. Fig. 3 is an enlarged view of a portion D of the display device 1 shown in Fig. 1. Fig. 4 is a rear view of the display device 1. Fig. 5 is a cross-sectional view of the display device 1 taken along the cutting line AA shown in Fig. 4. Fig. 6 is a cross-sectional view of the display device 1 taken along the cutting line BB shown in Fig. 4.

[0010] As shown in FIG. 1, an orthogonal coordinate system consisting 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 may be expressed as the front side, and the -X side may be expressed as the rear side. In addition, the -Y side may be expressed as the right side, the +Y side as the left side, the +Z side as the upper side, and the -Z side as the lower side. Furthermore, the surface of the +X side of the member may be expressed as the front side, and the surface of the -X side of the member may be expressed as the back side. The part located most forward of the member may be expressed as the front end, and the part located most rearward of the member may be expressed as the rear end.

[0011] In this specification, the expressions "parallel" or "perpendicular" include cases where two elements are not completely parallel or perpendicular. That is, "parallel" or "perpendicular" includes cases where two elements are substantially parallel or perpendicular, for example, deviated from parallel or perpendicular by a few degrees. In addition, in this specification, the expression "same" includes cases where two elements are not completely the same. That is, the expression "same" includes cases where two elements are substantially the same, for example, differing by about a few percent.

[0012] 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. The display device 1 may also include a support panel 13, a light control film 19, and a cable 23. Below, an example in which the display device 1 includes the support panel 13, the light control film 19, and the cable 23 will be described.

[0013] The display panel 12 displays an image on the front surface 121. The display panel 12 has a display area DA, which is an area for displaying an image, and a peripheral area PFA, which is an area in which circuits and the like are arranged. In addition, the display panel 12 can transmit external light incident from the front and rear in the display area DA. The display panel 12 is, for example, a transparent OLED (Organic Light Emitting) panel. The display panel 12 does not have to be a transparent OLED panel as long as it is a transparent display panel. For example, the display panel 12 may be a transparent LED (Light Emitting Diode) panel or a transparent micro LED panel in which the element size of an LED is miniaturized. In addition, any transparent display panel of a projection type or a self-luminous type may be used. The display device 1 is, for example, disposed between the front and rear seats of a vehicle, and is used as a partition and a display inside the vehicle.

[0014] The light control film 19 is disposed on the rear side of the display panel 12. The light control film 19 and the display panel 12 are attached to each other by an OCA (Optical Clear Adhesive) 18. The light control film 19 is capable of controlling light transmittance. The light control film 19 is switchable between a light transmitting state and a light blocking state. When external light is incident from behind, the contrast of the image displayed on the display panel 12 can be improved by switching the light control film 19 to a light blocking state when viewing the image displayed on the display panel 12 from the front. The light control film 19 has, for example, a liquid crystal material. The transmittance of the light control film 19 is controlled, for example, by changing the voltage applied to the liquid crystal material.

[0015] 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. The cover panel 11 is also translucent. That is, the cover panel 11 transmits light of an image on the display panel 12 forward. The cover panel 11 also transmits external light incident from the front and rear. The cover panel 11 and the display panel 12 are bonded together by an OCA 17. The cover panel 11 is made of, for example, glass. This makes the cover panel 11 less susceptible to scratches.

[0016] The cover panel 11 has a first region corresponding to the display area DA and a second region corresponding to the peripheral region. In FIG. 1, the boundary between the first region and the second region is indicated by a dashed line. The first region is the region inside the dashed line, and the second region is the region outside the dashed line. The second region on the front or back of the cover panel 11 may be colored. For example, the second region on the front or back of the cover panel 11 may be printed in black. Also, for example, a black tape may be attached to the second region on the front or back of the cover panel 11. By configuring in this way, it is possible to make the member located behind the second region less visible from the front. This can improve the design of the display device 1. Here, the member located behind the second region is, for example, a circuit or the like arranged in the peripheral region PFA in the display panel 12.

[0017] The support panel 13 is located behind the light control film 19. The support panel 13 and the light control film 19 are attached to each other by the OCA 20. The support panel 13 protects the light control film from external forces. The support panel 13 is also translucent, and transmits external light incident from the front and rear. The support panel 13 is formed of, for example, glass. This makes it possible to make the support panel 13 less susceptible to scratches.

[0018] The cover panel 11 and the support panel 13 may be made of, for example, resin instead of glass. By making the cover panel 11 and the support panel 13 out of resin, they become lighter than when made out of glass.

[0019] Also, another adhesive having light-transmitting properties may be used instead of the OCA 17, OCA 18, and OCA 20. For example, an OCR (Optical Clear Resin) may be used instead of the OCA.

[0020] The frame 14 supports the cover panel 11, the display panel 12, the light control 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 connecting surface 143, a back surface 144, a side surface 145, and a second connecting surface 146. The first front surface 141 is located forward of the second front surface 142. The first front surface 141 and the back surface of the cover panel 11 are parallel. Also, the second front surface 142 and the back surface of the support panel 13 are parallel. The first connecting surface 143 connects the first front surface 141 and the second front surface 142. The first connecting surface 143 extends so as to surround the side surface of the display panel 12, the side surface of the light control film 19, and the side surface of 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. Moreover, the side surface 145 is perpendicular to the front surface of the display panel 12, the first front surface 141, and the rear surface 144. The second connection surface 146 connects the second front surface 142 and the rear surface 144. When the display device 1 is viewed from the front, the second connection surface 146 is located 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 periphery of the display area DA. The second connection surface 146 is an inner side surface of the frame 14 having a frame shape. This prevents external light entering the display area DA from the front and rear of the display device 1 from being blocked by the frame 14.

[0021] The frame 14 and the cover panel 11 are attached to each other with double-sided tape 15. More specifically, the first front surface 141 and the rear surface of the cover panel 11 are attached to each other with the double-sided tape 15. Furthermore, the frame 14 and the support panel 13 are attached to each other with the double-sided tape 16. More specifically, the second front surface 142 and the rear surface of the support panel 13 are attached to each other with the double-sided tape 16. The frame 14 is formed from a metal material having high rigidity, such as an aluminum alloy or a magnesium alloy.

[0022] The bezel 21 is connected to the frame 14. The bezel 21 has a first side wall 211 and a second side wall 212. The bezel 21 may have a connection member 213, a rear wall 214, and a front wall 215. An example in which the bezel 21 has the connection member 213, the rear wall 214, and the front wall 215 will be described below. The bezel 21 is formed of, for example, a zinc-plated rigid plate or stainless steel. In this embodiment, the first side wall 211, the second side wall 212, the connection member 213, the rear wall 214, and the front wall 215 are formed using, 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 connection member 213, the rear wall 214, and the front wall 215 have, for example, the same thickness. The bezel 21 reduces damage to the display device 1 caused by an external force. In this specification, the expression "reducing damage" to a component also includes reducing the possibility that the component will be damaged.

[0023] The first side wall 211 surrounds the side surface 145. More specifically, the first side wall 211 has a frame shape surrounding the entire periphery 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. 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 opposite side of the first surface 2111. The first surface 2111 and the side surface 145 face each other. The first surface 2111 and the side surface 145 may be in contact with each other. In this embodiment, the first surface 2111 extends in the +X direction to a position facing 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 and the cover panel 11 overlap. On the other hand, the cover panel 11 is disposed with a gap between it and the first side wall 211. That is, the first surface 2111 and the side surface of the cover panel 11 do not contact each other. This makes it possible to make it difficult for an external force caused by, for example, a side impact to be transmitted to the first side wall 211. Therefore, damage to the cover panel 11 can be reduced.

[0024] The second side wall 212 is located on the opposite side of the first side wall 211 from the frame 14, and is spaced apart from the first side wall 211. The first portion 2113 and the second portion 2114 are parallel to the second side wall 212. The second side wall 212 extends in the Z direction along the first portion 2113 and the second portion 2114. The second side wall 212 is located outside at least one of the first portion 2113 and the second portion 2114. In this embodiment, the second side wall 212 is located outside the first portion 2113 and outside the second portion 2114, respectively.

[0025] 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 with the second surface 2112. In this embodiment, the third surface 2131 faces forward. The connecting member 213 may be formed integrally with the first side wall 211 or the second side wall 212. In this embodiment, the connecting member 213 is formed integrally with the second side wall 212, for example, using the same material.

[0026] The display device 1 includes the bezel 21 having the first side wall 211 and the second side wall 212, and thus damage to the display device 1 caused by an external force can be reduced. First, consider a case where an external force is applied to the display device 1 from the right or left direction. An 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 applied to the second side wall 212 first. Since the second side wall 212 is disposed at a distance from the first side wall 211, the second side wall 212 can collapse toward the first side wall 211. At that time, a part of the external force applied to the second side wall 212 is consumed as energy for the second side wall 212 to collapse. Therefore, the external force transmitted from the second side wall 212 to the first side wall 211 via the connection member 213 can be reduced. This can reduce damage to the first side wall 211. Reducing damage to the first side wall 211 can reduce damage to components located on the opposite side of the first side wall 211 to the second side wall 212. Here, the components located on the opposite side of the first side wall 211 to the second side wall 212 include, for example, the cover panel 11, the display panel 12, the light control film 19, and the support panel 13.

[0027] When viewed from the normal direction of the side surface 145, the front end of the connection member 213 overlaps with the front end of the frame 14 or is located behind the front end of the frame 14. In this embodiment, the front end of the connection member 213 is the third surface 2131. The front end of the frame 14 is the first front surface 141. With this configuration, an external force transmitted in the order of the second side wall 212, the connection member 213, and the first side wall 211 is easily transmitted from the first side wall 211 to the frame 14 and is less likely to be 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 connection member 213 is located forward of the front end of the frame 14, there is a possibility that the external force from the first side wall 211 is 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 connection member 213 to overlap with the front end of the frame 14 or to be located rearward of the front end of the frame 14, an external force can be easily transmitted from the first side wall 211 to the frame 14 and can be less likely to be transmitted to the cover panel 11. By making it difficult for an external force to be transmitted to the cover panel 11, damage to the cover panel 11 can be reduced. In this embodiment, the front end of the connection member 213 is located rearward of the front end of the frame 14. The further the connection member 213 is connected to the first side wall 211 at a position away from the cover panel 11, the less likely the external force is to be transmitted to the cover panel 11. Therefore, it is desirable for the connection member 213 to be connected to the rear end of the first side wall 211.

[0028] The rear wall 214 is connected to the frame 14. More specifically, the rear wall 214 is fixed to the frame 14 by the screws 22. In this embodiment, a total of four rear walls 214 are provided, two on each side of the display device 1, and each is connected to the frame 14. Each rear wall 214 is fixed to the frame 14 by two screws 22. Note that the number of rear walls 214 and the number of screws 22 are not limited to this. For example, one rear wall 214 may be provided on each side, or three or more rear walls 214 may be provided on each side. Also, each rear wall 214 may be fixed to the frame 14 by one screw 22, or three or more screws 22. The rear wall 214 is connected to the first side wall 211. As shown in FIG. 4, FIG. 5, and FIG. 6, the rear wall 214 in this embodiment is formed by folding back a part of the connection member 213 toward the frame 14 so as to contact the rear surface 144. 4, the connection member 213 has cutouts 2132. In this embodiment, the connection member 213 has four cutouts 2132. With this configuration, the display device 1 can be made lighter in weight.

[0029] An external force applied to the bezel 21 is easily transmitted to the frame 14 via the connection portion between the bezel 21 and the frame 14. Therefore, the farther the connection portion between the bezel 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, which is located far from the cover panel 11, to the frame 14, the external force transmitted to the cover panel 11 can be reduced.

[0030] 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 disposed at a distance from the cover panel 11. That is, the rear surface of the front wall 215 does not contact the front surface of the cover panel 11. This makes it possible to make it difficult for the external force applied to the second side wall 212 to be transmitted to the front wall 215 via the first side wall 211. In addition, the front wall 215 prevents the cover panel 11 from falling off forward of the front wall 215.

[0031] The cable 23 is electrically connected to the display panel 12. The cable 23 transmits a 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 a display element included in the display panel 12 via the cable 23 and a driver IC included in the display panel 12. The light emission of the display element is controlled by the driving signal. The cable 23 is located between the first side wall 211 and the second side wall 212. In this embodiment, three cables 23 are arranged between the first side wall 211 and the second side wall 212 located on the right side of the display device 1, and between the first side wall 211 and the second side wall 212 located on the left side of the display device 1. The number of cables 23 is not limited to this. For example, one or two cables 23 may be provided on each of the right and left sides of the display device, or four or more cables may be provided on each side. By disposing the cables 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 cables 23. Therefore, it is possible to reduce the external force without using a separate cushioning material.

[0032] As described above, the display device 1 of this embodiment includes the display panel 12, the cover panel 11, the frame 14, and the bezel 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 is translucent. The frame 14 supports the display panel 12 and the cover panel 11. The bezel 21 is connected to the frame 14. The frame 14 has a side surface 145 perpendicular to the front surface 121, and the bezel 21 has a first side wall 211 surrounding the side surface 145, and a second side wall located on the opposite side of the frame 14 with respect to the first side wall 211 and spaced apart from the first side wall 211.

[0033] With this configuration, the display device 1 of this embodiment can reduce damage to the display device 1 caused by an external force.

[0034] Second embodiment Hereinafter, a second embodiment of the display device according to the present disclosure will be described with reference to the drawings.

[0035] The display device 1a of this embodiment has a second side wall 212a instead of the second side wall 212 in the first embodiment. Since the other configurations are similar to those of the display device 1 of the first embodiment, the same components as those of the display device 1 of the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

[0036] Furthermore, in the following embodiments, in order to simplify the drawings, the OCA 18, the OCA 20, the light control film 19, the screws 22, and the cable 23 in the first embodiment may be omitted as appropriate.

[0037] FIG. 7 is a schematic cross-sectional view of the display device 1a taken along the same line as the cutting line BB shown in FIG.

[0038] The second side wall 212a is configured similarly to 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 greater than the thickness of the connection 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 connection 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 that is approximately twice as long in the +X direction as the length of the first side wall 211 in the X direction and has, for example, the same thickness as the connection member 213. Next, the side wall is folded from the +X direction to the -X direction so that the length in the X direction is approximately half. By configuring in this way, the thickness of the second side wall 212a is increased, and therefore the strength against external forces can be increased. Furthermore, when an external force is applied to the second side wall 212a, the second side wall 212a collapses toward the first side wall 211, and as a result, more energy is consumed. This makes it possible to further reduce the external force transmitted from the second side wall 212a to the first side wall 2111.

[0039] In this 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 be greater than approximately twice the thickness of the connecting member 213. For example, the thickness of the second side wall 212a may be approximately three times the thickness of the connecting member 213. Furthermore, the second side wall 212a does not need to be formed in a folded state as long as the thickness in the normal direction of the first surface 2111 can be increased. For example, the second side wall 212a may be cast so that the thickness in the normal direction of the first surface 2111 is increased.

[0040] The display device 1a of this embodiment includes a first buffer material 24, a second buffer material 25, and a protective film 26. Note that display devices in embodiments other than this embodiment described in this specification may also include the first buffer material 24, the second buffer material 25, and the protective film 26. The display device may include all three of the first buffer material 24, the second buffer material 25, and the protective film 26, or may include any one or any two of the three.

[0041] The first cushioning material 24 is located between the side surface 145 and the first surface 2111. The first cushioning material 24 is, for example, a rubber material. The first cushioning material 24 absorbs a part of the external force transmitted from the first side wall 211 to the frame 14. When an external force applied to the second side wall 212a is transmitted in this order to the connecting member 213 and the first side wall 211, and then to the frame 14, the first cushioning material 24 can absorb a part of the external force. Therefore, the external force transmitted to the frame 14 can be reduced, and damage to the frame 14 can be reduced.

[0042] The second cushioning material 25 is located between the rear surface of the front wall 215 and the front surface of the cover panel 11. The second cushioning material 25 is, for example, a rubber material. The second cushioning material 25 absorbs a part of the external force transmitted from the front wall 215 to the cover panel 11. When the external force transmitted to the second side wall 212a is transmitted in this order to the connecting member 213, the first side wall 211, and the front wall 215, and then to the cover panel 11, the second cushioning material 25 can absorb a part of the external force. Therefore, the external force transmitted to the cover panel 11 can be reduced, and therefore damage to the cover panel 11 can be reduced.

[0043] The protective film 26 covers the outer surfaces of the cover panel 11 and the frame 14. The protective film 26 protects the cover panel 11 and the frame 14. The protective film 26 can protect the cover panel 11 and the frame 14 from external forces, thereby reducing damage to the cover panel 11 and the frame 14. The protective film 26 is made of resin. The protective film 26 is made of, for example, PET (Polyethylene Terephthalate) resin, PP (Polypropylene) resin, or PVC (Polyvinyl Chloride) resin.

[0044] Third embodiment Hereinafter, a third embodiment of the display device according to the present disclosure will be described with reference to the drawings.

[0045] The display device 1b of this embodiment has a first side wall 211b instead of the first side wall 211 in the first embodiment. Moreover, the display device 1b does not have a front wall 215. Since the other configurations are similar to those of the display device 1 of the first embodiment, the same components as those of the display device 1 of the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

[0046] FIG. 8 is a schematic cross-sectional view of the display device 1b taken along the same line as the cutting line BB shown in FIG.

[0047] The first side wall 211b is configured similarly to 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 greater than the thickness of the connection 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 connection 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 that is approximately twice as long in the +X direction as the length of the second side wall 212 in the X direction and has the same thickness as the connection member 213. Next, the side wall is folded from the +X direction to the -X direction so that the length of the side wall in the X direction is approximately half. By configuring in this way, the thickness of the first side wall 211b is increased, and therefore the strength against external forces can be increased. Therefore, damage to the first side wall 211b can be reduced.

[0048] In this 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 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. Furthermore, the first side wall 211b does not need to be formed in a folded state as long as the thickness in the normal direction of the first surface 2111b can be increased. For example, the first side wall 211b may be cast so that the thickness in the normal direction of the first surface 2111b is increased.

[0049] Moreover, the display device 1b does not include a front wall 215. Display devices in embodiments other than this embodiment described in this specification may also not include the front wall 215. By not providing the front wall 215, it is possible to improve the design of the display device 1b when viewed from the front.

[0050] In the case where the display device does not have a front wall 215, as shown in FIG. 8, 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, the second side wall 212 can come into contact with the first side wall 211 but does not come into contact with the cover panel 11. Specifically, when viewed from the normal direction of the side surface 145, the front end of the second side wall 212 is preferably overlapped with the back surface of the cover panel 11 or is located behind the back surface of the cover panel 11. By configuring in this manner, even if an external force is applied to the second side wall 212 and the second side wall 212 falls toward the first side wall 211a, it is possible to make the second side wall 212 less likely to come into contact with the cover panel 11. Therefore, it is possible to reduce the possibility that the external force applied to the second side wall 212 is directly transmitted from the second side wall 212 to the cover panel 11. Therefore, it is possible to reduce damage to the cover panel 11.

[0051] (Fourth embodiment) Hereinafter, a fourth embodiment of the display device according to the present disclosure will be described with reference to the drawings.

[0052] The display device 1c of this embodiment has a first side wall 211c instead of the first side wall 211 in the first embodiment. The display device 1c also has a third side wall 216. In addition, the display device 1c does not have a front wall 215. Since the other configurations are similar to those of the display device 1 of the first embodiment, the same components as those of the display device 1 of the first embodiment are denoted by the same reference numerals and their description will be omitted.

[0053] FIG. 9 is a schematic cross-sectional view of the display device 1c taken along the same line as the cutting line BB shown in FIG.

[0054] The first side wall 211c is configured similarly to the first side wall 211 except for its 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 and the first front surface 141 overlap with each other.

[0055] 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. With this configuration, 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, the second side wall 212 may come into contact with, for example, the third side wall 216. At this time, since the position where the second side wall 212 and the third side wall 216 come into contact is far from the cover panel 11, 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 easily transmitted from the second side wall 212 to the third side wall 216 at the position where the second side wall 212 and the third side wall 216 contact each other, and then transmitted to the frame 14 via the first side wall 211 and the rear wall 214. This reduces the possibility that the external force applied to the second side wall 212 will be transmitted from the second side wall 212 to the cover panel 11. This reduces damage to the cover panel 11.

[0056] Fifth embodiment Hereinafter, a fifth embodiment of the display device according to the present disclosure will be described with reference to the drawings.

[0057] The display device 1d of the present embodiment has a configuration in which the display device 1c of the fourth embodiment further includes a front wall 215 and a fourth side wall 217. Since the other configurations are similar to those of the display device 1c of the fourth embodiment, the same components as those of the display device 1c of the fourth embodiment are denoted by the same reference numerals and descriptions thereof will be omitted.

[0058] FIG. 10 is a schematic cross-sectional view of the display device 1d taken along the same line as the cutting line BB shown in FIG.

[0059] 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 and the first side wall 211c are parallel. 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, the second side wall 212 may come into contact with, for example, the fourth side wall 217. At this time, since the position where the second side wall 212 and the fourth side wall 217 come into contact is far from the cover panel 11, 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 and the fourth side wall 217 contact each other, and is then easily transmitted to the frame 14 via the first side wall 211c and the rear wall 214. This reduces damage to the cover panel 11. In addition, the front wall 215 prevents the cover panel 11 from falling off forward of the front wall 215.

[0060] Sixth embodiment Hereinafter, a sixth embodiment of the display device according to the present disclosure will be described with reference to the drawings.

[0061] The display device 1e of the present embodiment includes a second side wall 212e instead of the second side wall 212 in the first embodiment. Since the other configurations are similar to those of the display device 1 of the first embodiment, the same components as those of the display device 1 of the first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

[0062] FIG. 11 is a schematic cross-sectional view of the display device 1e taken along the same line as the cutting line BB shown in FIG.

[0063] The second side wall 212e is configured similarly to 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, the second side wall 212e has a shape that draws an arc so as to protrude to the outside of the display device 1 when viewed from the Z direction. The second side wall 212e has a fourth surface 2121 and a fifth surface 2122. The fourth surface 2121 is a surface that faces the outside in the left-right direction of the display device 1. The fifth surface 2122 is a surface that intersects with 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 falls toward the first side wall 211, the front end of the second side wall 212e may come into contact with the first side wall. At this time, the external force applied to the second side wall 212e is dispersed to two places: the front end of the second side wall 212e, and the second side wall 212e and the connecting member 213. As a result, the external force applied to the second side wall 212e is dispersed and then transmitted to the first side wall 211, so that damage to the first side wall 211 and to the frame 14 and the cover panel 11 to which the external force may be transmitted via the first side wall 211 can be reduced. Here, the front end of the second side wall 212e is the side shared by the fourth surface 2121 and the fifth surface 2122. Moreover, the front end of the frame 14 is the first front surface 141.

[0064] Furthermore, 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. With this configuration, the front end of the second side wall 212e contacts the first side wall 211 behind the front end of the frame 14. This makes it possible for an external force to be easily transmitted to the frame 14 and less likely to be transmitted to the cover panel 11. For example, if the front end of the second side wall 212e contacts the first side wall 211 forward of the front end of the frame 14, there is a possibility that an external force directly transmitted from the second side wall 212e to the first side wall 211 will 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 behind the front end of the frame 14, an 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 can be difficult to transmit to the cover panel 11. By making it difficult for the external force to be transmitted to the cover panel 11, damage to the cover panel 11 can be reduced. In this embodiment, the front end of the second side wall 212e is located behind the front end of the frame 14. The further away from the cover panel 11 the position where the second side wall 212e and the first side wall 211 contact each other, the less likely the external force is to be transmitted to the cover panel 11. Therefore, by positioning the front end of the second side wall 212e behind the front end of the frame 14, the external force transmitted to the cover panel 11 can be reduced.

[0065] Seventh embodiment Hereinafter, a seventh embodiment of the display device according to the present disclosure will be described with reference to the drawings.

[0066] The display device 1f of this embodiment includes a frame 14f instead of the frame 14 in the first embodiment. The display device 1f also includes a rear wall 214f ​​instead of the rear wall 214. Since the other configurations are similar to those of the display device 1 of the first embodiment, the same components as those of the display device 1 of the first embodiment are denoted by the same reference numerals and descriptions thereof will be omitted.

[0067] FIG. 12 is a schematic cross-sectional view of the display device 1f taken along the same line as the line AA shown in FIG.

[0068] The frame 14f is configured similarly to the frame 14, except that the frame 14f is formed so that the corners are cut off. The frame 14f has a first front surface 141, a second front surface 142, a first connecting surface 143, a back surface 144, a side surface 145, a second connecting surface 146, and a slope 147. The slope 147 extends in a direction intersecting with the side surface 145. The slope 147 is located behind the side surface 145. The slope 147 connects the side surface 145 and the back surface 144. The frame 14f is formed so that the corners formed by the back surface 144 and the side surface 145 of the frame 14 are cut off. By configuring in this manner, the frame 14f can be made smaller.

[0069] The rear wall 214f ​​is configured similarly to 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. By providing the first rear wall 2141 along the outer shape of the frame 14f in this manner, it is possible to reduce the size of the rear wall 214f.

[0070] The second rear wall 2142 faces the rear surface 144 and extends along the rear 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 the screws 22. An external force applied to the bezel 21f is easily transmitted to the frame 14f via the connection portion between the bezel 21f and the frame 14f. Therefore, the further the connection portion between the bezel 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 farther from the cover panel 11 to the frame 14f, the external force transmitted to the cover panel 11 can be reduced.

[0071] Although each embodiment of the present disclosure has been described above, the above-mentioned embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. These new embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims. Furthermore, components across different embodiments and modifications may be appropriately combined.

[0072] Furthermore, the effects of each embodiment described in this specification are merely examples and are not intended to be limiting, and other effects may also be provided.

[0073] (Additional Note) One aspect of the present disclosure is as follows. [Item 1] A display panel for displaying an image on the front side; a cover panel located in front of the display panel and having light-transmitting properties; a frame supporting the display panel and the cover panel; a bezel connected to the frame, the frame has a side perpendicular to the front surface; The bezel has a first side wall surrounding the side surface, and a second side wall located on the opposite side of the first side wall from the frame and spaced apart from the first side wall. Display device. According to this embodiment, since the second side wall is disposed at a distance from the first side wall, when an external force is applied to the second side wall, the second side wall can collapse toward the first side wall. At that time, a part of the external force applied to the second side wall is consumed as energy for the second side wall to collapse, so that the external force transmitted to the first side wall can be reduced accordingly. [Item 2] the bezel has a connection member that connects the first side wall and the second side wall, When viewed from a normal direction of the side surface, a front end of the connection member overlaps with a front end of the frame or is located rearward of the front end of the frame. Item 1. A display device according to item 1. According to this embodiment, an external force that is 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 difficult to be transmitted to the cover panel. For example, compared to a case in which the front end of the connecting member is located forward of the front end of the frame when viewed from the normal direction of the side surface of the frame, the external force is easily transmitted from the first side wall to the frame and difficult to be transmitted to the cover panel. By making it difficult for the external force to be transmitted to the cover panel, damage to the cover panel can be reduced. [Item 3] The first side wall has a first surface facing the side surface and a second surface located opposite to the first surface, the connecting member has a third surface that intersects with the second surface, The thickness of the first side wall in a normal direction to the first surface is greater than the thickness of the connection member in a normal direction to the third surface. Item 2. A display device according to item 2. According to this aspect, the first side wall has a large thickness, which increases its strength against external forces and reduces damage to the first side wall. By reducing damage to the first side wall, it is possible to reduce damage to each member located on the opposite side of the first side wall from the second side wall and the possibility of each member falling off. [Item 4] The first side wall has a first surface facing the side surface and a second surface located opposite to the first surface, the connecting member has a third surface that intersects with the second surface, The thickness of the second side wall in a normal direction to the first surface is greater than the thickness of the connection member in a normal direction to the third surface. Item 2. The display device according to item 2 or 3. According to this aspect, the second side wall has a larger thickness, and therefore has a higher strength against external forces. As a result, when an external force is applied to the second side wall, the second side wall collapses and consumes more energy, so that the external force transmitted to the first side wall can be further reduced. [Item 5] The second side wall is curved so as to protrude in a direction away from the frame. Item 5. The display device according to any one of items 1 to 4. According to this embodiment, when an external force is applied to the second side wall, the second side wall falls toward the first side wall, and the front end of the second side wall comes into contact with the first side wall. Therefore, the external force applied to the second side wall is distributed to two places: the front end of the second side wall and the connection part between the second side wall and the connection member. As a result, the external force applied to the second side wall is distributed and then transmitted to the first side wall, so that damage to the first side wall and to the frame and cover panel to which the external force is transmitted via the first side wall can be reduced. [Item 6] When viewed from a normal direction of the side surface, a front end of the second side wall overlaps with a front end of the frame or is located rearward of the front end of the frame. Item 5. The display device according to item 5. According to this aspect, when an external force is applied to the second side wall, the front end of the second side wall comes into contact with the first side wall behind the front end of the frame, which makes it possible for the external force to be easily transmitted to the frame and less easily transmitted to the cover panel. [Item 7] the bezel has a rear wall connected to the first side wall; The rear wall is connected to the frame. 7. The display device according to any one of items 1 to 6. External forces applied to the second side wall are easily transmitted to the frame via the connection between the bezel and the frame. In this case, the farther the connection between the bezel 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 embodiment, by connecting the rear wall located far from the cover panel to the frame, the impact transmitted to the cover panel can be reduced. [Item 8] The frame has an inclined surface extending in a direction intersecting with the side surface and positioned rearward of the side surface, The rear wall has a first rear wall connected to the first side wall and facing the inclined surface. Item 8. The display device according to item 7. According to this aspect, the frame can be made smaller by forming the frame so that the corners are cut off, and the rear wall can be made smaller by forming the rear wall to follow the outer shape of the frame. [Item 9] The frame has a back surface that is perpendicular to the side surface and is connected to the sloped surface, the rear wall has a second rear wall connected to the first rear wall and facing the back surface; the second rear wall is connected to the frame; Item 9. The display device according to item 8. According to this aspect, by providing the second rear wall and connecting the second rear wall to the frame, the connection portion between the bezel and the frame is far from the cover panel, so that the external force transmitted to the cover panel can be reduced. [Item 10] a cable electrically connected to the display panel and transmitting a signal for driving the display panel to the display panel; The cable is located between the first side wall and the second side wall. Item 10. The display device according to any one of items 1 to 9. According to this embodiment, the external force applied to the second side wall is absorbed by the cable electrically connected to the display panel, so that the external force can be reduced without providing a separate cushioning material. [Item 11] the bezel has a front wall connected to the first side wall; The front wall extends along the front surface of the cover panel. 11. The display device according to any one of items 1 to 10. According to this aspect, by providing the front wall, for example, when an external force is transmitted to the cover panel, it is possible to prevent the cover panel from falling off forward of the front wall. [Item 12] the bezel has a third side wall connected to the first side wall; The third side wall extends from the first side wall in a direction away from the side surface of the cover panel. 11. The display device according to any one of items 1 to 10. According to this embodiment, 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, since the position where the second side wall and the third side wall come into contact is far from the cover panel, the external force transmitted to the cover panel can be reduced. [Item 13] the bezel has a front wall connected to the third side wall; The front wall extends along the front surface of the cover panel. Item 13. A display device according to item 12. According to this aspect, by providing the front wall, for example, when an external force is transmitted to the cover panel, it is possible to prevent the cover panel from falling off forward of the front wall.
