2. Description of the Related Art A liquid crystal display element (hereinafter, referred to as LCD) and a flexible wiring board (hereinafter, referred to as FPC) are connected to each other, and an LCD holding member is used to hold the LCD and the FPC, and each electrode has conductivity. There is a configuration to connect with a rubber connector. A conventional example of the holding member of the holding member when the LCD has only one row of electrodes is shown in FIG.
A protrusion 44 is provided on the back side of the bottom portion 43 of the CD holding member 41, and a slit 45 parallel to the bottom surface of the LCD holding member 41 is formed in the protrusion 44. F in that slit
The electrode portion 48a of the PC 48 is inserted, and then the rubber connector 46 is fitted into the rubber connector housing portion 42 formed on the inner bottom surface of the LCD holding member 41 to be connected to the FPC electrode portion 48a. The FPC and the LCD are electrically connected by placing and pressing the LCD 49 and the pressing frame 47 from above.

However, as the function of the electronic device is improved, it is necessary to display more information on the function display section. However, when the amount of information to be displayed is increased, the number of terminals of the display element is increased and the number of terminals cannot be set in one row. To have columns. LC
In the conventional connection configuration in which the D electrode row is provided on the two opposite sides, as shown in FIG. 9, the FPC 55 is placed and fixed on the LCD holding member 51, and the FPC electrode rows 55a and 55b are fixed from above. The rubber connector holding member 52 is placed on the portion where the rubber connector holding member 52 is vacant so that the portion does not overlap with the portion on which the rubber connector is placed. Then, the rubber connectors 53 are fitted in the vacant portions, that is, two groove-shaped portions where the electrode rows are exposed on the bottom, and the LCD 56 and the pressing frame 54 are pressed from above to electrically connect them. There is.

[0004]

However, in the construction of the holding member in the case where the LCD shown in the conventional example has two rows of electrodes, the assembly and disassemblability are good, but a separate rubber connector holding member is required. The number of parts will increase. Further, by applying the configuration in the case of one electrode row, the configuration of the holding member 61 in the case where there are two rows on the opposite sides of the electrode row as shown in FIG. 10 can be considered. In this case, the slits 65 provided in the protrusion 64 are formed to face each other, and the FPC 68 is temporarily bent to insert the electrode portions 68a and 68b into the slit 65. However, when attempting to separate the FPC 68 with this configuration, a thin rod-shaped member or the like must be forcibly separated in the gap between the FPC 68 in the middle of the two rows of electrodes and the bottom surface of the LCD holding member, which makes the work difficult. Is. Further, when the FPC has a uniform hardness, a force for separation is applied to the entire surface of the FPC, which may warp the FPC or damage the electrode portion. SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve these problems and provide a display device holding member that can cope with a display element having a plurality of electrode rows and can be easily separated from an FPC without increasing the number of parts. I am trying.
