In particular, a large-sized liquid crystal display is most suitable for use with a direct-lit backlight module. The structure of a conventional direct-lit backlight module is described below. Please refer to FIG. 1 , which is a schematic diagram showing a part of the structure of a conventional direct type backlight module. The backlight module 100 includes a frame 30, a light emitting diode module (LED module) 15, a reflective sheet 21, a diffusion sheet group 22, and at least one support structure 10. The support structure 1 is One-piece structure. The frame 30 has a bottom plate 30a, a side plate 3汕 and a top plate 3〇c. The side plate 3 is connected to the bottom plate 30a and the top plate 30c. The side plate 30b and the bottom plate 30a define an accommodation space 30d. The light emitting diode module 15 is disposed on the bottom plate 30a in such a manner as to be located in the accommodating space 3〇d, and has a light emitting surface 15a. The bottom end of the support structure 1 is fixed to the bottom plate 30a to stand in the accommodating space 30d. The side of the support structure ι has a bump 11 and a lower bump 12 spaced apart from each other, and the distance between the upper bump u and the lower bump 12/ 5 1282025 is exactly equal to the thickness of the reflective sheet 21, and the upper bump u can It is elastic = angular structure. The reflective sheet 20 is placed in the accommodating space 30d so as to be penetrated by the supporting structure 1 〇 and the illuminating surface, so that the reflecting sheet 2 is sandwiched by the upper bump 11 and the lower bump, and is illuminated by the diode module. Group 15 is supported. In this way, the reflective sheet '21 can be located above the bottom plate' for reflecting the light L emitted from the light-emitting surface 15a of the light-emitting diode module 15. When the support structure 10 is attached to the reflection sheet 21, first, the through-hole of the reflection sheet 21 is aligned with the top end of the support structure 1 . Next, the reflective sheet 2 i is placed along the support structure! 〇 • It is falling. Then, the upper bump n is pressed by an external force to allow the reflection sheet 2 to pass. The reflection sheet 21 can continue to slide down through the upper bumps and fall between the upper bumps 11 and the lower & blocks 12. When the external force is released, the upper bump u will return to its original state. The sergeant bump 12 holds the reflection sheet 21 up and down. When the reflection sheet 21 and the support structure W are to be separated, first, the upper projection u is pressed by an external force to allow the reflection sheet 21 to pass. Next, the reflection sheet 21 is slid upward. When the reflection sheet 21 passes the upper projection iu4, the external force can be removed to make the upper projection! i restore the original state. As long as the reflection sheet h is continuously slid upward, the reflection sheet 21 and the support structure 1〇 can be completely separated. • Further, the diffusion sheet group 22 is composed of one or two diffusion sheets. The diffusion sheet group 22 is disposed above the light-emitting diode module 15 and supported by the branch structure ι〇 = top end. After the light-emitting diode module 15 emits the light 1, the light is diffused by the diffuser module 22 to form a light source. ' ' However, in assembling the branch structure 10 and the reflecting sheet, it is necessary to press the upper bump u with a sufficient external force to cause the reflecting sheet 21 to pass through the upper bump 11. This way of assembly: : It is quite troublesome. Although a support structure 10 is exemplified herein, the backlight module 100 is usually supported by a plurality of mutually spaced branch structures 1 〇 in the process of assembling the reflective sheet 21, and the reflective sheet is required. ^ Simultaneously traverse the upper bumps n, 6.1282025 ' on the top of the structure 1G, or separate the reflection sheet 21 and the support structure ι from the entire surface. Therefore, it is more complicated in the assembly process. In addition, in order to enable the reflection sheet 2 1 to pass through the upper projection 丨丨, the upper projection 丨丨 cannot be too convex. Therefore, when the backlight module 1 is inverted, the upper bump u cannot "support the reflective sheet 21 like the lower bump 12". Therefore, the upper bump n and the valley are liable to cause structural damage, thereby causing the reflection sheet 21 to be separated from the support structure. In addition, since the point light source of the light-emitting diode module 15 is diffused into the surface light source only by the diffusion sheet group 22, a certain distance is required between the light-emitting diode module 15 and the diffusion sheet group 22. Moreover, the conventional backlight module 1 is supported by the top end of the supporting structure 1 to support the diffusion sheet group 22, so that the backlight module 1 must have a considerable thickness to achieve the desired diffusion effect. SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a backlight module and a liquid crystal display device i, which is provided with two sets of separated diffusion sheets # and is matched with the design of the movable support mechanism.
