Description of the Invention: [Technical Field] The present invention relates to a backlight module and a liquid-violet display device using the same. [Prior Art] The liquid crystal display device has many advantages such as thinness, low power consumption, low radiation, and the like, and has been widely used in electronic products such as mobile phones and digital cameras. The liquid crystal display device usually includes a liquid crystal panel. However, since the liquid crystal of the liquid crystal panel itself does not emit light, in order to achieve the display effect, it is necessary to provide a light source device such as a backlight module for the liquid crystal panel to realize the function. The two backlight modules are generally classified into an edge-lit backlight module and a direct-lit backlight module according to the structure. With the continuous expansion of the application field of liquid crystal display devices, especially the large-scale: the application of liquid display devices, such as LCD TVs, the requirements for the brightness of the moonlight module of liquid crystal display devices are further improved, and multiple light sources are needed to The backlight module of the two backlight modules has been unable to meet the requirements of higher light transmittance, so the direct backlight module has gradually become the mainstream of large-size liquid crystal display devices. Please refer to Figure 1, which is a front view of a prior art backlight module. The backlight module 10 is a direct type backlight module, and includes a protrusion 11, a plurality of line sources 12, a frame 13 and a plurality of electrode holders 14, the frame! 3 accommodating the plurality of line sources 12, the plurality of electrodes are fixed (6) and 14 and supporting the diffuser u, the plurality of electrode holders n are the electrodes of the line source 12. 200912444 The frame 13 is an open (not labeled) frame structure including a bottom plate 131 and a plurality of side walls 132 extending obliquely outward from the edge of the bottom plate 131. Wherein the base plate ι31 is made of a high reflectivity material or a surface of which a reflective sheet is attached. The diffuser plate is a flat plate structure that is mounted on the side wall 132 of the frame 13 and covers the opening of the frame 13. The line source 12 is generally a cold cathode fluorescent lamp tube disposed between the diffusion plate 11 and the bottom plate 131, and the adjacent two-line light source 12 is fixed to the bottom plate 131 by the opposing two-electrode holder 14. When the image is displayed by the liquid crystal display device (not shown) of the backlight module 10, the line source 12 emits light, a part of the light directly hits the diffuser 11 and another part of the light passes through the frame 13. The reflection plate of the bottom plate 131 or the surface of the bottom plate 131 is reflected and is incident on the diffusion plate n, and then diffused by the diffusion plate 11 to form a flat light having uniform brightness output to the panel of the liquid crystal display device (not shown). However, as the size of the liquid crystal display device becomes larger, the size of the line source 12 in the backlight module 10 also becomes larger, which generally reduces the structural strength of the line source 12, causing the line source 12 to be impacted by external force or When it is affected by vibration, it is more likely to break. At the same time, when the size of the liquid crystal display device becomes large, the size of the diffusing plate 11 of the moonlight module 10 is correspondingly increased. The diffuser 11 of the larger size is susceptible to bending deformation under its own weight, resulting in deterioration of the optical characteristics of the diaphragm module 1 . Modules To overcome the above drawbacks, the backlight 20 shown in Figure 2 is commonly used in the industry to enhance its structural strength and improve its optical quality. The back 200912444 optical module 20 further includes a plurality of support members 24 and a plurality of bolts 25 with respect to the backlight module 10. The bottom plate 231 of the frame 23 of the backlight module 20 is provided with a plurality of perforations (not shown) penetrating the bottom plate, and the plurality of perforations respectively correspond to the plurality of support members 24. The support member 24 includes a post 241 and a light stand 242 extending upwardly perpendicular to the light stand 242. The support post 241 is a conical structure, and one end thereof is provided with a screw hole (not shown) which matches the perforation of the bottom plate 231 and is threadedly nested with the bolt 25. Each of the lamp holders 242 includes a strip-shaped support plate 243 and two sets of rings 244. The two sets of rings 244 are all c-shaped structures, which are respectively disposed at two ends of the support plate 243. The two sets of rings 244 are symmetrically distributed in the support column 24: the axes are symmetric axes. The line source 22 passes through the support member collar 244' and is secured to the base 242 of the support frame 24. When assembling, firstly, the screw hole at the end of the support column 241 is aligned with the hole of the frame 23, and secondly, the bolt is engaged with the screw hole of the support column 241 to fix the support member 24 to the support member 24 The frame u is second and second, and the female first-line light source 22 is sleeved and fixed on the collar ^4 of the support member 24, thereby realizing the fixing of the line light source 22. Finally, the expansion is disposed on the side wall. The other end of the branch 241 abuts the & expansion board 21, thereby completing the assembly of the backlight module 2〇. The backlight module 20 is provided with a support 24 on its frame 23, and the other end of the support member 24 abuts and supports the diffusion plate 21 to avoid warping deformation of the expansion plate 21. At the same time, the line source 22 is fixed on the support 12112444 24 to avoid the deformation of the line caused by the line source 22 being too long. However, each support member in the backlight module 20 /
