By equipping the front and back side metal plates with flexible spring-like presser plates, even when physical or mechanical stress is applied to the metal plate from the outside, the flexible spring-like presser plates can be used. The structure absorbs stress, and almost no stress is applied to the joint between the LCD panel and the LCD drive board. For this reason, the LCD panel, terminals, and LCD
The reliability of the electrical connection with the conductor pattern on the drive board is improved, and the strength of the front and back metal plates themselves can be reduced, making them thinner and lighter.
