設計の自由度が制限される。However, in such a liquid crystal display mounting structure, since a large number of the first fixing screws E and the second fixing screws F are used, the screwing process is troublesome and the first fixing screws are difficult. Due to the use of E, the manufacturing cost is high. Further, since the shape and size of the liquid crystal display device D and the mounting ear d are predetermined by the manufacturer's specifications, the degree of freedom in the mounting design of the front panel B manufactured by the electronic device manufacturer is limited.
