Abstract

The invention relates to a backlight module and a liquid crystal display device. In the backlight module, edge of a shell is designed into a folding edge structure capable of serving as appearance, so that the thickness for shading possibly exposed shell metal section cannot be reserved on the first vertical edge of a front frame, the thickness of the front frame is reduced, an inward concave structure is designed at intersection position of a back board and vertical edge of the back board and used for placing a folding edge of a shell, and width increase of the liquid crystal display device caused by design of the folding edge of the shell is avoided. According to the backlight module, the metal section exposed by a rear shell cannot be shaded by a front frame without changing other sizes, the thickness of the front frame is reduced, and thin design of the liquid crystal display device is achieved.

Description

technical field [0001] The invention relates to the field of liquid crystal television backlights, in particular to a backlight module and a liquid crystal display device. Background technique [0002] In the existing backlight module, the back shell is fixed on the back plate by means of screw connection, etc., and the side of the back shell is a metal section that cannot be surface-treated, and thus cannot be used as an appearance; in the prior art, the front frame is usually added thickness, and use the increased thickness of the front frame to cover the metal section. Therefore, in the existing backlight module, the thickness of the front frame is increased, which is not conducive to the thinner design of the liquid crystal display device. [0003] specific, figure 1 It is a structural schematic diagram of a backlight module in the prior art, figure 2 It is a functional schematic diagram of a backlight module in the prior art. Such as figure 1 As shown, the backlig...
