     Patent Literature 
     PTL 1: Unexamined Japanese Patent Publication No. 2007-156176 
     SUMMARY 
     Display devices are getting larger. Also, a size of a mounting section for mounting a holding member such as a supporting column has tended to increase in order to suppress an inclination of the display device in the front-rear direction, vibration in a width direction, and the like. On the other hand, when the entire thickness of the display device increases due to the increase in size of the mounting section, it is difficult to make the display device thinner. 
     The present disclosure provides a display device that can be held by a holding member in a stable state while design of the display device is being improved, and a back plate used in the display device. 
     The display device according to the present disclosure includes a display panel that displays an image and a back plate that holds the display panel. The back plate has mounting sections, a plurality of vertically bulging sections, and a laterally bulging section. The mounting sections are disposed on a plurality of positions on an edge part of one end of the back plate, and holding members that hold the display device are mounted to the mounting sections respectively. The vertically bulging sections bulge out from a reference surface of the back plate, and extend from near one ends of the mounting sections to an edge part of the other end of the back plate on an opposite side from the one end of the back plate. The laterally bulging section bulges out from the reference surface, extends along an edge of the other end of the back plate, and has a length larger than a distance between the vertically bulging sections adjacent to each other. 
     The display device of the present disclosure can be held by the holding member in a stable state while increase in thickness is suppressed, even if the display device has a large size.

     First Exemplary Embodiment 
     1-1. Outline of Configuration of Display Device 
       FIG. 1  is a perspective view schematically illustrating one example of an external appearance of display device  100  according to the first exemplary embodiment. 
       FIG. 2  is an exploded perspective view schematically illustrating one example of a structure of display device  100  according to the first exemplary embodiment. 
     Noted that these drawings schematically illustrate an outline configuration of display device  100  and the details are omitted. 
     Note that XYZ axes are used below for the description as necessary. In this exemplary embodiment, a direction parallel (substantially parallel) to a longer side direction of display device  100  is defined as an X axis direction, a direction parallel (substantially parallel) to a shorter side direction of display device  100  is defined as an Y axis direction, and a direction orthogonal to both the X axis and the Y axis is defined as a Z axis direction, for the sake of convenience. In addition, the vertical direction with respect to the XZ plane, that is, the Y-axis direction, is the direction of gravitational force. Under a normal use condition, display device  100  is supposed to be installed on an installation surface parallel (substantially parallel) to the XZ plane. Further, a side of display device  100  that faces a user (not illustrated) viewing display device  100  is defined as a “front side” or a “front”, and a side opposite to the front side is defined as a “back side” or a “back”. A side relatively distant from the installation surface in the Y-axis direction is defined as “upper (or top) side”, and a side relatively close to the installation surface in the Y-axis direction is defined as “lower (or bottom) side”. Moreover, a direction parallel (substantially parallel) to the shorter side direction of display device  100  is defined as “vertical”, and a direction parallel (substantially parallel) to the longer side direction of display device  100  is defined as “widthwise (or lateral)”. Note that these directions are given as relative directions for descriptive purpose but not absolute ones. 
     Display device  100  includes frame  101 , front member  102 , display panel  103 , light-emitting unit  140 , back plate  108 , and back cover  109 . 
     Display device  100  described in this exemplary embodiment is a television that outputs images or sounds obtained from received broadcast waves, etc., and contains a circuit board (not illustrated). Noted that the configuration as a television is substantially identical to a commonly known configuration, so that the description thereof will be omitted. In addition, display device  100  is mounted to holding members  200 . Holding member  200  encompasses members called a leg or a base (pedestal, stand), a bracket for mounting display device  100  to a wall or a ceiling, and the like. 
     Frame  101 , front member  102 , and back cover  109  are components that cover display panel  103 , light-emitting unit  140 , and the like. Frame  101  is a member that protects outer perimeters of display panel  103 , and the like. Front member  102  is a transparent member that covers a front surface of display panel  103 . Back cover  109  is a member that protects back surfaces of display panel  103  and the like. 
     Display panel  103  is a device that displays an image based on an input video signal. The image includes a still image, a moving image, and the like, and also includes characters, symbols, and the like. Display panel  103  described in this exemplary embodiment is a liquid crystal display panel. In addition, a thickness of display panel  103  is about 1 mm to 3 mm, for example. Note that the type of display panel  103  is not particularly limited in the present disclosure. Display panel  103  may include a display panel that does not need light-emitting unit  140  on the back surface side of display panel  103 . 
     1-2. Light-Emitting Unit 
     Light-emitting unit  140  is a component for radiating light with substantially uniform luminance to the back surface of display panel  103 , and generally called a “backlight”. Light-emitting unit  140  includes diffusion plate  104 , reflection sheet  105 , and light-emitting module  106 . 
     Light-emitting module  106  is configured such that several of a plurality of light-emitting sources  161  included in display device  100  are mounted to wiring board  162 . Light-emitting module  106  is provided so that light-emitting sources  161  can be easily disposed on back plate  108 . Light-emitting sources  161  can be arranged in a matrix along display panel  103  by mounting light-emitting module  106  to back plate  108 . 
     Note that a recessed part (not illustrated) for mounting light-emitting module  106  is formed on back plate  108 . 
     Wiring board  162  is provided with a connector. On wiring board  162 , electric power supplied from an electric line connected to the connector is supplied to light-emitting sources  161  mounted to wiring board  162 . Thus, light-emitting sources  161  mounted on wiring board  162  are turned on. 
     Light-emitting sources  161  are arranged in a matrix along display panel  103  (along the X axis and the Y axis). Light-emitting sources  161  are components that radiate light toward display panel  103  from the back surface side of display panel  103 . Although the type of light-emitting sources  161  is not particularly limited in the present disclosure, examples of light-emitting sources  161  include a white LED which is formed by combining a blue light-emitting diode and a fluorescence material emitting yellow and can radiate white light. 
     Diffusion plate  104  is a member that diffuses light radiated from the plurality of light-emitting sources  161 . For example, diffusion plate  104  diffuses incident light in substantially all directions to reduce viewing angle dependency in luminance of radiated light, thereby making the luminance of the radiated light substantially uniform. As one specific example, diffusion plate  104  is a plate-shaped transparent member having fine irregularities on both surfaces or only on one surface. In addition, microparticles having high reflectivity may be dispersed in diffusion plate  104 . Further, diffusion plate  104  may be formed by laminating a plurality of films with fine irregularities in layers. 
     Reflection sheet  105  is a member that reflects light radiated from light-emitting sources  161  to display panel  103 . Reflection sheet  105  is provided with insertion holes into which light-emitting sources  161  are inserted. Note that the diameter of each insertion hole may be set to be larger than the outer shape of each of light-emitting sources  161  so that light-emitting source  161  can be easily inserted into the insertion hole. 
     In the present disclosure, the material of reflection sheet  105  is not particularly limited. For example, a white sheet-shaped member made of synthetic resin such as polyethylene terephthalate (PET) having excellent light reflectivity can be used as reflection sheet  105 . In addition, reflection sheet  105  has flexibility (elasticity) that enables swelling-out (deformation) due to partial pushing-out by protrusion (not illustrated). 
     1-3. Back Plate 
       FIG. 3  is a perspective view schematically illustrating one example of a back part of back plate  108  according to the first exemplary embodiment. 
     Back plate  108  is a plate-shaped member that holds display panel  103 , and is disposed on the back surface (a surface in the negative direction of the Z axis) of display panel  103  as illustrated in  FIG. 2 . As illustrated in  FIG. 3 , back plate  108  has mounting sections  181 , vertically bulging sections  182 , and laterally bulging section  183 . Notably, back plate  108  is also provided with a bulging section (recessed section) for holding light-emitting module  106 , bosses for fastening light-emitting module  106  and a circuit board with screws, but they are not illustrated. 
       FIG. 4  is an enlarged plan view illustrating the vicinity of mounting section  181  in the first exemplary embodiment. 
       FIG. 5  is an enlarged perspective view illustrating the vicinity of mounting section  181  to which holding member  200  is mounted in the first exemplary embodiment. 
     Mounting sections  181  are formed on an edge part of a lower end of back plate  108 , and are a portion of back plate  108 . Each mounting section  181  is formed such that holding member  200  for holding display device  100  can be mounted to thereto. 
     Noted that mounting sections  181  may be disposed on positions where holding members  200  can hold back plate  108  in a balanced and stable manner. Specifically, the above-mentioned edge part of the lower end of back plate  108  means a range where each holding member  200  mounted to each of mounting sections  181  can hold back plate  108  in a balanced and stable manner. 
     In the present exemplary embodiment, attachment fitting  189  for mounting holding member  200  is fixed to mounting sections  181  respectively. 
     Attachment fitting  189  is a member that can improve the structural strength of mounting section  181  and can facilitate and ensure the mounting of holding member  200  to back plate  108 . 
     As illustrated in  FIGS. 3 and 4 , each of vertically bulging sections  182  is a portion of back plate  108 , and is configured to have a width (a length in the longer side direction (the X-axis direction) of back plate  108 ) larger than the width of mounting section  181 , bulge out backward from reference surface  184 , and extend from the vicinity of upper end part  181   a  of mounting section  181  to an edge part of an upper end of back plate  108 . Note that reference surface  184  means a surface, on the back surface of back plate  108 , which is flush with mounting sections  181  to each of which holding member  200  is mounted. 
     Noted that the lower end and the upper end of vertically bulging section  182  may be set within a range by which sufficient rigidity of back plate  108  can be obtained. Specifically, the vicinity of upper end part  181   a  of mounting section  181  means a region from a position where the lower end of vertically bulging section  182  is in contact with upper end part  181   a  of mounting section  181  to a position where the lower end of vertically bulging section  182  is apart from upper end part  181   a  of mounting section  181  by a distance by which the rigidity of back plate  108  is not impaired. In addition, the edge part of the upper end of back plate  108  means a region where sufficient rigidity of back plate  108  can be obtained by vertically bulging sections  182 . 
     Note that, in the present exemplary embodiment, the bulging section (including vertically bulging sections  182  and laterally bulging section  183 ) means a part formed such that a portion of a thin plate-shaped member bulges out and projects to one side. Therefore, the bulging section projects as viewed from one surface of the plate-shaped member (as viewed from the back surface side of back plate  108  in the example in  FIG. 3 ), while it is recessed as viewed from the other surface (as viewed from the front surface side of back plate  108  in the example in  FIG. 3 ). 
     In this exemplary embodiment, mounting sections  181  and vertically bulging sections  182  are provided to positions on back plate  108  for dividing back plate  108  into substantially three equal parts or almost three equal parts in the widthwise (lateral) direction (the longer side direction (the X-axis direction) of back plate  108 ), as illustrated in  FIG. 3 . Thus, holding members  200  can hold back plate  108  in a balanced manner with the number of mounting sections  181  and vertically bulging sections  182  formed on back plate  108  being reduced. 
     In addition, vertically bulging sections  182  are not disposed on edge parts of ends in the widthwise (lateral) direction (the longer side direction (the X-axis direction) of back plate  108 ) of back plate  108 . This configuration can give, to a user, the impression of the thinness of display device  100  as viewed from a side of display device  100 , and thus design of display device  100  can be improved 
     In addition, as illustrated in  FIG. 3 , vertically bulging sections  182  extend along a top-bottom direction (the shorter side direction (Y-axis direction) of back plate  108 ) of back plate  108 . Thus, the rigidity of display device  100  in the front-back direction (the thickness direction (Z-axis direction) of back plate  108 ) can be improved. 
     Noted that a part of vertically bulging section  182  in the top-bottom direction may be narrower than mounting section  181  to ensure a region where a circuit board and the like are disposed. In other words, at least a part of vertically bulging section  182  may be wider than mounting section  181 . 
     In addition, back plate  108  has reinforcement bulging sections  185  as illustrated in  FIG. 4 . Each of reinforcement bulging sections  185  is provided on a side of mounting section  181  and extends from the lower end of vertically bulging section  182  to substantially an intermediate position of mounting section  181  beyond upper end part  181   a  of mounting section  181 . 
     Like vertically bulging sections  182 , reinforcement bulging sections  185  are formed to bulge out backward from reference surface  184 . Due to the configuration in which each reinforcement bulging section  185  is disposed on a side of each of mounting sections  181 , the mechanical strength on mounting sections  181 , in the front-back direction (the Z-axis direction), can be increased in the state in which each holding member  200  is mounted to each of mounting sections  181 . 
     In the present exemplary embodiment, each reinforcement bulging section  185  is formed continuously with each of vertically bulging sections  182  in the top-bottom direction (the Y-axis direction). In addition, as illustrated in  FIG. 4 , reinforcement bulging section  185  has an inclined section  186  of which bulging height is gradually decreased toward the bottom (in the negative direction of the Y axis) from the bulging surface of vertically bulging section  182 . Noted that the bulging height means a length from reference surface  184  to the bulging surface in the front-back direction (the Z-axis direction) of back plate  108 . 
     Note that the inclination angle of inclined section  186  is set to be less steep than an inclination angle of tapered section  187  of vertically bulging section  182 . Further, a width (the length in the X-axis direction) of reinforcement bulging section  185  is set to be a width as substantially same as a width obtained by subtracting the width of mounting section  181  (the length in the X-axis direction) from the width of vertically bulging section  182  (the length in the X-axis direction). 
     This configuration enables the manufacture of reinforcement bulging sections  185  to be facilitated with the mechanical strength on mounting sections  181  being sufficiently ensured. In addition, the provision of inclined section  186  can improve the design at the lower end part of display device  100 . 
     As illustrated in  FIG. 3 , laterally bulging section  183  is a portion of back plate  108  that extends along an edge of the upper end (in the X-axis direction) of back plate  108  and is formed into a shape bulging out backward from reference surface  184 . The length (a size in the X-axis direction) of laterally bulging section  183  is set to be longer than the distance between vertically bulging sections  182  provided on two positions of back plate  108  in the X-axis direction. 
     In this exemplary embodiment, laterally bulging section  183  extends throughout almost the entire lateral width (the width of back plate  108  in the longer side direction (the X-axis direction)) of rectangular reference surface  184 , and is formed continuously with vertically bulging sections  182 . That is, laterally bulging section  183  and vertically bulging sections  182  are connected to each other into a T shape at ends of vertically bulging sections  182 . In addition, the bulging height of laterally bulging section  183  (the length from reference surface  184  to the bulging surface in the Z-axis direction) is set to be almost equal to the bulging height of vertically bulging sections  182  so that the bulging surface of laterally bulging section  183  is substantially flush with the bulging surfaces of vertically bulging sections  182 . Further, the width of laterally bulging section  183  (the size in the Y-axis direction) is set to be narrower than the width (the size in the X-axis direction) of vertically bulging sections  182 . 
     Thus, in display device  100 , the structural strength due to vertically bulging sections  182  can be extended to the edge parts of ends of back plate  108  in the widthwise (lateral) direction (the X-axis direction), so that the strength in the rotation direction of display device  100  around the top-bottom direction (the strength with respect to deflection in the Z-axis direction) can be increased. 
     Further, as illustrated in  FIG. 3 , laterally bulging section  183  is formed across reference surface  184  from near an intermediate position of inclined frame section  188  disposed on the peripheral edge of back plate  108 . Note that inclined frame section  188  is a portion of back plate  108  and is configured to be closer to display panel  103  toward the peripheral end edge of back plate  108 . In other words, inclined frame section  188  is a portion of back plate  108  and is configured such that an opening area becomes larger according as inclined frame section  188  is near to display panel  103 . 
     This configuration enables the rigidity of back plate  108  to be increased. 
     In the present exemplary embodiment, vertically bulging sections  182 , laterally bulging section  183 , and reinforcement bulging sections  185  are formed integrally with back plate  108 , and formed simultaneously with back plate  108  during the manufacture of back plate  108  by performing plastic deformation working on a metal plate. One example of a method for manufacturing back plate  108  will be described. For example, a metal plate is subjected to press working using a die so that vertically bulging sections  182 , laterally bulging section  183 , reinforcement bulging sections  185 , inclined frame section  188 , etc. can be formed. 
     Note that back plate  108  has also bulging sections (not illustrated) other than vertically bulging sections  182  and laterally bulging section  183 . However, vertically bulging sections  182  and laterally bulging section  183  are formed to have a bulging height larger than a height of other bulging sections. 
     1-4. Effects and the Like 
     As described above, in the present exemplary embodiment, the display device includes a display panel that displays an image and a back plate that holds the display panel. The back plate has mounting sections, a plurality of vertically bulging sections, and a laterally bulging section. The mounting sections are disposed on a plurality of positions on an edge part of one end of the back plate, and holding members that hold the display device are mounted to the mounting sections respectively. The vertically bulging sections bulge out from a reference surface of the back plate, and extend from near one ends of the mounting sections to an edge part of the other end of the back plate on an opposite side from the one end of the back plate. The laterally bulging section bulges out from the reference surface, extends along an edge of the other end of the back plate, and has a length larger than a distance between the vertically bulging sections adjacent to each other. 
     Note that display device  100  is one example of the display device. Display panel  103  is one example of the display panel. Back plate  108  is one example of the back plate. Mounting section  181  is one example of the mounting section. Vertically bulging section  182  is one example of the vertically bulging section. Laterally bulging section  183  is one example of the laterally bulging section. Holding member  200  is one example of the holding member. The lower end of back plate  108  is one example of one end of the back plate. The upper end of back plate  108  is one example of the other end of the back plate. Reference surface  184  is one example of the reference surface of the back plate. Upper end part  181   a  of mounting section  181  is one example of one end of the mounting section. 
     According to this configuration, in display device  100  described exemplary in the first exemplary embodiment, for example, design can be improved by decreasing the thickness of display device  100 . In addition, the entire rigidity of a display device set in which holding members  200  are mounted to display device  100  can be increased. Further, in display device  100 , the mechanical strength for obtaining high rigidity can be implemented by the structure of vertically bulging sections  182  and laterally bulging section  183  provided to back plate  108 . Accordingly, the production, installation, etc. of display device  100  can be facilitated, the deformation of display device  100  and the like can be suppressed. 
     In the display device, each of the vertically bulging sections may have a width larger than a width of each of the mounting sections. The back plate may have reinforcement bulging sections each of which is provided on a side of each of the mounting sections and extends from one end of the vertically bulging section to position beyond the one end of the mounting section. 
     Note that the length of vertically bulging section  182  in the X-axis direction (the longer side direction of back plate  108 ) is one example of the width of the vertically bulging section. Reinforcement bulging section  185  is one example of the reinforcement bulging section. The lower end of vertically bulging section  182  is one example of one end of the vertically bulging section. Substantially the intermediate position of mounting section  181  is one example of the position beyond the one end of the mounting section. 
     According to this configuration, in display device  100  described exemplary in the first exemplary embodiment, rigidity can be increased. In addition, the mechanical strength on mounting sections  181 , in the front-back direction (the Z-axis direction), can be increased in the state in which each holding member  200  is mounted to each of mounting sections  181 . 
     In the display device, each of the reinforcement bulging sections may have an inclined section which has a bulging height gradually decreasing toward the one end of the back plate. 
     Note that inclined section  186  is one example of the inclined section. The length from reference surface  184  to the bulging surface in the front-back direction (the Z-axis direction) of back plate  108  is one example of the bulging height. 
     According to this configuration, in display device  100  described exemplary in the first exemplary embodiment, design on the lower end part of display device  100  can be improved with the mechanical strength on mounting sections  181  being ensured. 
     Other Exemplary Embodiments 
     As presented above, the first exemplary embodiment has been described as an example of the technique disclosed in the present application. However, the technique in the present disclosure is not limited to the above description, and is applicable to embodiments to which modification, replacement, addition, omission, or the like is made. In addition, the constituent elements described in the first exemplary embodiment can be combined to form a new embodiment. 
     In view of this, other exemplary embodiments will be described below. 
     The first exemplary embodiment describes display device  100  including a liquid crystal display panel and a direct backlight. However, display device  100  may include an organic electroluminescence (EL) display panel or other display panels. 
     The first exemplary embodiment has described the configuration example in which vertically bulging section  182  has a width larger than a width of mounting section  181 . However, the present disclosure is not limited to this configuration. Vertically bulging section  182  may have a width smaller than a width of mounting section  181 . 
     The first exemplary embodiment has described the configuration in which a plurality of light-emitting sources  161  is mounted to wiring board  162  as light-emitting module  106 . However, wiring board  162  may be configured by a flexible printed circuit (FPC), and wiring board  162  that contains electric lines for supplying electric power to wiring board  162  may be configured by an FPC. If various boards and wiring lines are formed by an FPC, routing of wiring lines becomes easy, so that reflection sheet  105  provided to back plate  108  can be flatly attached. 
     The first exemplary embodiment has described the configuration example in which the bulging height of vertically bulging sections  182  and laterally bulging section  183  is set larger than the bulging height of other bulging sections (not illustrated). However, the present disclosure is not limited to this configuration. Display device  100  may have a bulging section with a bulging height larger than the height of vertically bulging sections  182  and laterally bulging section  183 . 
     The first exemplary embodiment has described the configuration example in which reinforcement bulging section  185  is provided on one side of mounting section  181 . However, the present disclosure is not limited to this configuration. Reinforcement bulging section  185  may be provided on both sides of mounting section  181 . 
     The first exemplary embodiment has described the configuration example in which laterally bulging section  183  and vertically bulging sections  182  are connected to each other into a T shape at the ends of vertically bulging sections  182 . However, the present disclosure is not limited to this configuration. For example, laterally bulging section  183  and vertically bulging sections  182  may intersect each other in a “+” shape (or in an “X” shape) at the intermediate portion of laterally bulging section  183  and the intermediate portions of vertically bulging sections  182 . 
     The first exemplary embodiment has described the configuration example in which back plate  108  has two vertically bulging sections  182  and one laterally bulging section  183 . However, the present disclosure is not limited to this configuration. Back plate  108  may have three or more vertically bulging sections  182 , or two or more laterally bulging sections  183 . 
     As presented above, the exemplary embodiments have been described as an example of the technique in the present disclosure. For this purpose, the accompanying drawings and the detailed description are provided. 
     Therefore, the components in the accompanying drawings and the detail description may include not only components essential for solving problems, but also components that are provided to illustrate the above described technique and are not essential for solving problems. Therefore, such inessential components should not be readily construed as being essential based on the fact that such inessential components are shown in the accompanying drawings or described in the detailed description. 
     Further, the above described embodiments have been described to exemplify the technique according to the present disclosure, and therefore, various modifications, replacements, additions, omissions, and the like may be made within the scope of the claims and an equivalent scope of the claims.
