[0026] like Figure 1-2 As shown, in one embodiment, the backlight module 2 is located in the slot between the cover plate 1 and the middle frame 4, and the length and width of the top view of the cover plate 1 are adapted to the length and width of the top view of the middle frame 4.

It should be noted that the antistatic layer 3 is mainly attached to the edge of the LCD display 13.
