BACK PANEL, BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided are a back panel (100), a backlight module (300) and a liquid crystal display device (400). The back panel (100) comprises a main frame formed by splicing at least two parts to be spliced (110, 120), wherein each of the parts to be spliced (110, 120) comprises a bottom wall (111) and a side wall (112) arranged in a bent manner relative to the bottom wall (111); the outer side of the side wall (112) is provided with a snapping hook (113), and the snapping hook (113) is a screw fixed to the side wall (112). The back panel (100) is formed by splicing more than two parts to be spliced (110, 120), so that the production cost of the back panel (100) is reduced, and in turn the production costs of the backlight module (300) and the liquid crystal display device(400) are reduced. Moreover, the back panel (100) has a snapping hook (113) formed by locking a screw, and can be applied to the application occasions where the snapping hook could not be easily formed by stamping, thereby facilitating the assembly of the backlight module (300).
