       SUMMARY OF INVENTION 
     Technical Problem 
       [0022]    However, in the display device  1001  as the conventional example shown in  FIG. 31 , the engagement holes  1022   a  and the protrusion portions  1011   a  are disposed in and on the four edges (four side wall portions), accordingly, there are problems that the workability when demounting the front side bezel  1020  from the frame  1010  deteriorates and it takes a long time to demount the front side bezel  1020  from the frame  1010 . 
         [0023]    Likewise, in this display device  1001 , the engagement holes  1032   a  and the protrusion portions  1011   b  are disposed in and on the four edges (four side wall portions), accordingly, there are problems that the workability when demounting the rear side bezel  1030  from the frame  1010  deteriorates and it takes a long time to demount the rear side bezel  1030  from the frame  1010 . 
         [0024]    In other words, in the display device as the conventional example, there is a problem that it takes a long time to disassemble the display device  1001 . 
         [0025]    The present invention has been made to solve the above problems, and it is an object of the present invention to provide a display device that is capable of shorten an assembly time and a disassembly time. 
       Solution to Problem 
       [0026]    To achieve the above object, a display device according to one aspect of the present invention includes: a frame that holds a display panel; and a bezel that is disposed on at least one of a front side and a rear side of the frame; wherein one of the frame and the bezel is provided with a protrusion portion; the other of the frame and the bezel is provided with a guide portion that includes a first guide portion which is engaged with the protrusion portion and extends in a first direction along a surface direction of the display panel; one of the frame and the bezel is provided with a hook portion; the other of the frame and the bezel is provided with an engagement hole that is engaged with the hook portion when the protrusion portion is slid in the first direction along the first guide portion of the guide portion; and the engagement hole has a function to alleviate the hook portion moving in a direction along the first direction. 
         [0027]    Here, the present specification describes that one of the frame and the bezel is provided with the protrusion portion and one of the frame and the bezel is provided with the hook portion, which however means that both of the protrusion portion and the hook portion may be disposed on the same member (the frame or the bezel), or the protrusion portion and the hook portion may be disposed on separate members (the frame and the bezel). It goes without saying that this applies to the guide portion and the engagement hole. Besides, this applies to a positioning portion and a positioning hole that are described later; for example, the positioning portion may be disposed on the same member as the protrusion portion or may be disposed on a member separate from the protrusion portion. 
         [0028]    In the display device according to this one aspect, as described above, the one of the frame and the bezel is provided with the protrusion portion; the other of the frame and the bezel is provided with the guide portion that is engaged with the protrusion portion; the one of the frame and the bezel is provided with the hook portion; and the other of the frame and the bezel is provided with the engagement hole that is engaged with the hook portion when the protrusion portion is slid in the first direction along the first guide portion of the guide portion. According to this, by sliding the protrusion portion in the first direction along the guide portion, it is possible to engage the hook portion with the engagement hole and fix the bezel to the frame. In other words, it is possible to assemble the display device without using a screw, accordingly, it is possible to improve the assembly workability and shorten the assembly time of the display device. Besides, it is possible to improve the workability when disassembling the display device, accordingly, it is also possible to shorten the disassembly time of the display device. 
         [0029]    Besides, in the display device according to the one aspect, as described above, by forming the first guide portion of the guide portion to extend in the first direction along the surface direction of the display panel, by means of the protrusion portion and the first guide portion of the guide portion, it is possible to alleviate the bezel moving with respect to the frame in a direction that intersects the surface direction of the display panel. Besides, the engagement hole is formed to be engaged with the hook portion when the protrusion portion is slid in the first direction along the first guide portion of the guide portion and to alleviate the hook portion moving in the direction along the first direction. According to this, by means of the hook portion and the engagement hole, it is possible to alleviate the bezel moving in the surface direction of the display panel with respect to the frame. In other words, it is possible to alleviate the bezel coming off the frame. 
         [0030]    Besides, according to the above structure, it is not necessary to dispose the hook portion and the engagement hole on and in the four edges (four outer edge portions) of the frame and the bezel, accordingly, it is possible to more improve the assembly workability and disassemble workability of the display device. According to this, it is possible to more shorten the assembly time and disassembly time of the display device. Here, for example, in a case where the hook portion and the engagement hole are disposed on and in the four edges (four outer edge portions) of the frame and the bezel, thanks to dimensional unevenness of the components, a difference occurs in fitting workability (or demounting workability). Specifically, a disadvantage occurs, in which it is easy to fit in (or demount from) two edges (two outer edge portions) but hard to fit (or hard to demount) in the remaining two edges and the like. 
         [0031]    In the display device according to the above one aspect, preferably, the frame includes a plurality of the outer edge portions, and the hook portion or the engagement hole is disposed on or in one outer edge portion of the plurality of outer edge portions. According to this structure, compared with a case where the hook portion or the engagement hole is disposed on or in two or more outer edge portions of the plurality of outer edge portions, it is possible to decrease the fixing (engagement) portions, accordingly, it is possible to more improve the workability when demounting the bezel from the frame. According to this, it is possible to more shorten the disassembly time of the display device. 
         [0032]    In the display device according to the above one aspect, preferably, in a case where the hook portion is disposed on the frame, the hook portion is disposed near an end portion of the frame in the slide direction of the bezel when mounting the bezel on the frame; in a case where the hook portion is disposed on the bezel, the hook portion is disposed near an end portion of the bezel in a direction opposite to the slide direction. According to this structure, during a time the bezel is slid with respect to the frame, it is possible to alleviate the hook portion touching the member (bezel or frame) in which the engagement hole is disposed, accordingly, it is possible to alleviate the bezel becoming hard to slide with respect to the frame. According to this, it is possible to alleviate the assembly workability and disassembly workability of the display device deteriorating. 
         [0033]    In the display device according to the above one aspect, preferably, the guide portion includes a second guide portion that is connected to the first guide portion and extends in a direction which intersects the surface direction of the display panel. According to this structure, by moving the protrusion portion along the second guide portion, thereafter, sliding the protrusion portion along the first guide portion, it is possible to easily fix the bezel to the frame. Besides, by disposing the second guide portion on the guide portion, compared with a case where the guide portion is formed on the first guide portion only that extends in the first direction along the surface direction of the display panel, it is possible to shorten a moving distance of the bezel with respect to the frame. According to this, it is possible to improve the assembly workability and disassembly workability of the display device. 
         [0034]    In the display device according to the above one aspect, preferably, an end portion of one of the frame and the bezel in the direction opposite to the slide direction of the bezel when mounting the bezel on the frame is provided with a positioning portion that protrudes in a direction along the slide direction; and an end portion of the other of the frame and the bezel in the direction opposite to the slide direction is provided with a positioning hole that engages with the positioning portion. According to this structure, in the direction opposite to the slide direction of the bezel when mounting the bezel on the frame, it is possible to fix the bezel to the frame with high accuracy, and by means of the positioning portion and the positioning hole, it is possible to alleviate the bezel moving (coming off) with respect to the frame in the direction that intersects the surface direction of the display panel. 
         [0035]    In the display device that is provided with the above positioning portion and positioning hole, preferably, the frame is formed of a resin; and the positioning portion is formed integrally with the frame. According to this structure, it is possible to easily dispose the positioning portion on the frame. 
         [0036]    In the display device according to the above one aspect, preferably, the frame is formed of a resin; and the protrusion portion is formed integrally with the frame. According to this structure, it is possible to easily dispose the protrusion portion on the frame. Here, in a case where the guide portion is disposed on the resin frame, a slide core becomes necessary for a forming mold of the frame, a structure of the forming mold becomes complicated, and the cost becomes high. 
         [0037]    In the display device according to the above one aspect, preferably, the frame is formed of a resin; and the hook portion is formed integrally with the frame. According to this structure, it is possible to easily dispose the hook portion on the frame. 
         [0038]    In the display device according to the above one aspect, preferably, the bezel includes a front side bezel disposed on the front side of the frame and a rear side bezel disposed on the rear side of the frame. As described above, in the case where the bezel includes the front side bezel and the rear side bezel, the time shortening effect becomes double, which is more effective. 
         [0039]    In the display device in which the bezel includes the front side bezel and the rear side bezel, preferably, the protrusion portion is disposed on the frame; the guide portion is disposed on the front side bezel and the rear side bezel; and the protrusion portion of the frame is engaged with both of the guide portion of the front side bezel and the guide portion of the rear side bezel. According to this structure, it is not necessary to dispose separately the protrusion portion for fixing the front side bezel and the protrusion portion for fixing the rear side bezel. Here, in a case where the protrusion portion for the front side bezel for engaging with the guide portion of the front side bezel and the protrusion portion for the rear side bezel for engaging with the guide portion of the rear side bezel are separately disposed on the frame, for example, it is necessary to dispose a cutout portion on the rear side bezel for avoiding the protrusion portion for the front side bezel. 
         [0040]    In the display device in which the bezel includes the front side bezel and the rear side bezel, preferably, an end portion of the frame in the direction opposite to the slide direction of the bezel when mounting the bezel on the frame is provided with a positioning portion that protrudes in the direction along the slide direction; an end portion of the front side bezel and an end portion of the rear side bezel in the direction opposite to the slide direction are provided with a positioning hole that engages with the positioning portion; and the positioning portion of the frame is engaged with both of the positioning hole of the front side bezel and the positioning hole of the rear side bezel. According to this structure, in the direction opposite to the slide direction of the bezel when mounting the bezel on the frame, it is possible to fix the bezel to the frame with high accuracy, and by means of the positioning portion and the positioning hole, it is possible to alleviate the bezel moving with respect to the frame in the direction that intersects the surface direction of the display panel. 
         [0041]    Besides, by engaging the positioning portion of the frame with both of the positioning hole of the front side bezel and the positioning hole of the rear side bezel, it is not necessary to dispose separately the positioning portion for fixing the front side bezel and the positioning portion for fixing the rear side bezel. Here, in a case where the positioning portion for the front side bezel for engaging with the positioning hole of the front side bezel and the positioning portion for the rear side bezel for engaging with the positioning hole of the rear side bezel are separately disposed on the frame, for example, it is necessary to dispose a cutout portion on the rear side bezel for avoiding the positioning portion for the front side bezel. 
         [0042]    In the display device according to the above one aspect, preferably, the frame includes a plurality of outer edge portions; and the protrusion portion or the guide portion is disposed on a pair of outer edge portions of the plurality of outer edge portions that are disposed to oppose each other.

This also applies to the positioning portion and the positioning hole, and for example, the positioning portion and the protrusion portion may be formed on the same member, or the positioning portion and the protrusion portion may be formed on separate members. 
         [0140]    Besides, in the above embodiments, the example is described, in which the positioning portion is formed on the frame and the positioning hole is formed in the bezel (front side bezel and rear side bezel); however, the present invention is not limited to this, and the positioning portion may be formed on the bezel (front side bezel and rear side bezel) and the positioning hole may be formed in the frame. Besides, the positioning portion and the positioning hole may not be formed. 
         [0141]    Besides, in the above embodiments, the example is described, in which the positioning portion of the frame is formed to be the cylindrical shape or the conical trapezoidal shape; however, the present invention is not limited to this, and the positioning portion of the frame may be formed to be a polygonal shape or a polyhedral pyramidal trapezoidal shape. 
         [0142]    Besides, in the above embodiments, the example is described, in which the frame is formed of the resin and the bezel (front side bezel and rear side bezel) is formed of the metal plate; however, the present invention is not limited to this, and the frame may be formed of a material other than the resin, and the bezel (front side bezel and rear side bezel) may be formed of a material other than the metal plate. 
         [0143]    Besides, in the above embodiments, the example is described, in which the protrusion portion, which engages with both of the guide portion (cutout portion) of the front side bezel and the guide portion (cutout portion) of the rear side bezel, is formed on the frame; however, the present invention is not limited to this, and the protrusion portion for engaging with the guide portion (cutout portion) of the front side bezel and the protrusion portion for engaging with the guide portion (cutout portion) of the rear side bezel may be formed on separate members. 
         [0144]    Besides, in the above embodiments, the example is described, in which the positioning portion, which engages with both of the positioning hole of the front side bezel and the positioning hole of the rear side bezel, is formed on the frame; however, the present invention is not limited to this, and the positioning portion for engaging with the positioning hole of the front side bezel and the positioning portion for engaging with the positioning hole of the rear side bezel may be separately formed on the frame. 
         [0145]    Besides, in the above embodiments, the example is described, in which the protrusion portion of the frame is formed to be the L shape; however, the present invention is not limited to this, and the protrusion portion of the frame may be formed to be a cylindrical shape or a polygonal shape. 
         [0146]    Besides, in the above embodiments, the example is described, in which the cutout portion for engaging with the protrusion portion of the frame is formed on the front side bezel and the rear side bezel; however, the present invention is not limited to this, and as in a first modification of the present invention shown in  FIG. 29 , a concave-shaped guide portion  121  for engaging with the protrusion portion of the frame may be formed on a bezel  120  (front side bezel and rear side bezel). Here, it is easier to form the cutout portion on the metal-plate bezel  120  than to form a dimple (concave-shaped guide portion  121 ) in production and the cost becomes inexpensive, accordingly, it is preferable to form the cutout portion on the metal-plate bezel. 
         [0147]    Besides, in the above embodiments, the example is described, in which the front side bezel and the rear side bezel are formed of the separate members; however, the present invention is not limited to this, and as in a second modification of the present invention shown in  FIG. 30 , a bezel  220 , in which the front side bezel and the rear side bezel are integrally formed with each other, may be used. In this case, a guide portion (a concave portion (dimple) or a cutout portion)  221  extending in only the B direction is formed on the bezel  220 , and a frame  210  is inserted from a side of the bezel  220 . Besides, in this case, the hook portion  15  may be formed, for example, on only a front surface (upper surface) of the frame  210 . Here, in the case where the front side bezel and the rear side bezel are integrally formed with each other, it is necessary to weld the front side bezel and the rear side bezel to each other, whereby the productivity (workability) deteriorates and the slide distance of the frame  210  with respect to the bezel  220  becomes large. Because of this, it is preferable to separately form the front side bezel and the rear side bezel. 
         [0148]    Besides, in the above embodiments, the example is described, in which after the rear side bezel is fixed to the frame, the front side bezel is fixed to the frame; however, the present invention is not limited to this, and after the front side bezel is fixed to the frame, the rear side bezel may be fixed to the frame.
