The upper portion includes a first fixing member extending in the direction of the x-axis. The back panel houses the frame and includes four side edges and a bottom plate </ RTI> wherein the side edges include a second fixing member </ RTI> along the yoke for engaging the first fixing member. τ 0U76-TW/A06007 6 1334953 The structure of the frame and the backboard of the present invention is such that the second fixing member is fastened to the first fixing member by the second fixing member, so that the upper portions of the two first strip-shaped frames of the frame are kept flat with each other. Straight, without causing a concave phenomenon in the upper part of the two first strip-shaped frames. The above and other objects, features, and advantages of the present invention will become more apparent from the accompanying drawings. - Embodiments Referring to FIG. 4A, a backlight module 400 of an embodiment of the present invention is shown, which can be used in a liquid crystal display device, such as a liquid crystal display device similar to the first figure, which includes a front frame, A liquid crystal panel and a backlight module 400. The backlight module 4 is used to illuminate the liquid crystal panel, and includes a backing plate 419 which is combined with the front frame to combine the liquid crystal panel and the backlight module '400 into the liquid crystal display device. In this embodiment, the backlight module 400 is a direct-lit backlight module, but the present invention can also be applied to a side-lit backlight module, depending on the configuration of the light source or the light source unit. The backlight module 400 further includes a door type frame 4〇5, an optical film set, a reflector 4 17 and a light source unit 40 b. The door type frame 405 is made of plastic. The gate-shaped frame 4〇5 defines an xyz coordinate and includes two first strip-shaped frames extending along the γ-axis direction and a second strip-shaped frame 433 extending in the X-axis direction, wherein The second strip-shaped frame 433 is connected to one end of the two first strip-shaped frames 43 1 . The optical film group such as the diffusion sheets 4U, 4i3 and the diffusion plate 415 are disposed in the ^-shaped frame 405, and the light rays emitted from the light source unit 4〇1 are directed to the liquid crystal panel. The reflector 417 is disposed between the optical film set and the bottom plate 435 of the back plate 419, and the light emitted from the light source unit 〇1 is directed to the optical film set. The light source unit 401, such as a lamp tube or a light emitting diode system, is fixed to the light source unit fixing member 409 and disposed between the optical film group and the reflecting plate 417. The back plate 4 19 can be made of metal, such as aluminum, magnesium and its corresponding alloys, etc., for accommodating the door-shaped frame 405, the optical film set, the reflector 4 17 and the light source unit 40. 1, and includes four sides 437 and the bottom plate 4 3 5 . In this embodiment, the backlight module 400 further includes a strip 403 disposed at the other end of the two strip-shaped frames 433 for fixing the optical film set. Generally, the two first strip-shaped frames 43 have grooves (not shown) to slide the optical film set in the Y-axis direction, and the strip is fixed by mounting the strips 403. Optical film set.
