One end of an FPC (flexible printed wiring board) 37, which is a wiring sheet, is connected to the liquid crystal panel 31, and the other end of the FPC 37 is connected to the circuit board 27 shown in FIG. The FPC 37 is a wiring sheet which is a sheet-like wiring in which a large number of wirings are incorporated, and as shown in FIG. Is formed.

  Further, as shown in FIG. 3A, the protective frame 5 includes a substantially rectangular main plate 5a serving as a bottom plate, and side walls formed perpendicular to the main plate 5a with a predetermined gap at the peripheral edge of the main plate 5a. 5b and a standing wall 5c which is formed perpendicular to the main plate 5a in the gap portion of the side wall 5b and serves as a pressure-proof reinforcing portion. The height of the side wall 5b and the standing wall 5c of the protective frame 5 is higher than the thickness (height) of the liquid crystal display device 3. Therefore, when the liquid crystal display device 3 is housed in the protective frame 5, the ends of the side walls 5b and the standing walls 5c of the protective frame 5 protrude outward from the outermost surface of the liquid crystal display device 3.

  As shown in FIG. 3B, the liquid crystal display device 3 is accommodated in the protective frame 5 from the back side (the liquid crystal case 35 side), and the liquid crystal display device 3 is accommodated in the protective frame 5. In this case, the FPC 37 is disposed in the gap portion of the side wall 5b of the protective frame 5, and the standing wall 5c of the protective frame 5 is inserted into the through hole 37a of the FPC 37.

The liquid crystal display device 3 can be housed and fixed to the protective frame 5 provided with the pressure proof reinforcing portion by inserting the standing wall 5c as the pressure proof reinforcing portion of the protective frame 5 with the piercing portion as a through portion. Then, by using the FPC 37 formed on the circuit board connection portion side, the wiring incorporated in the FPC 37 is scratched as in the previous embodiment using the FPC 37 formed on the liquid crystal panel connection portion side. Even when connecting to the circuit board 27 described above, when the FPC 37 is pulled out to the circuit board 27, each leg portion is thin, so that it is pulled out to the circuit board 27 in a small space. This makes it easy to change the internal design of the electrical equipment.

  The terminal portion to which the FPC 37 of the liquid crystal display device 3 is connected is divided into two terminal groups and arranged adjacent to each other. Two FPCs 37 are connected to the two terminal groups, and the space between the two FPCs 37 is between them. It can also be set as the structure made into an insertion part. When two FPCs 37 are used in this way, the use of a general-purpose FPC 37 eliminates the need to create the FPC 37 as a dedicated product for electrical equipment in the present embodiment, thus realizing cost reduction and easily. An insertion part can be formed.

  Further, in the display device unit 1 described in the embodiments so far, the display device unit 1 was housed in the protective frame 5 from the back side of the liquid crystal display device 3, but as shown in FIG. An opening 5f is formed in the main plate 5a of the protective frame 5, and as shown in FIG. 8 (b), a liquid crystal display is provided in the protective frame 5 with a standing wall 50c inserted through the FPC 37 as a pressure proof reinforcement. The device 3 may be stored from the display surface side.

  Thus, when the display device unit 1 covered with the protective frame 5 from the display surface side of the liquid crystal display device 3 is mounted on an electronic device, the rigidity of the substrate or the like housed in the electronic device is fixed. Even if the window frame 13a of the display window of the rear housing 13 is deformed inward by external pressure, the window frame 13a hits the main plate 5a of the protective frame 5, so that a load is applied to the liquid crystal display device 3. Can be prevented.

  In this embodiment, a liquid crystal display device is used as the display device, but the present invention is not limited to this, and the present invention can also be applied to other display devices such as EL. Further, although a digital camera is described as an electric device in which a display device unit is arranged, the present invention can be applied to all electric devices in which a display device is incorporated, such as a mobile phone. Furthermore, although FPC37 is used as a wiring sheet, it is not limited to this. And this invention is not limited to the above Example, A change and improvement are possible freely in the range which does not deviate from the summary of invention.
