The above and other objects, features and advantages of the present invention will become more apparent and understood.乍评,,,田呑兄 [Embodiment] FIG. 2A is an exploded view of a direct type backlight module of the creation-embodiment, and FIG. 2B is a combination diagram of the direct type backlight module of FIG. 2A, and FIG. 2C It is a schematic perspective view of the back surface of the fixing piece and the buffer piece of FIG. 2A. . Referring to FIG. 2A , FIG. 2B and FIG. 2C , the direct type backlight module 200 of the embodiment includes a bottom plate 210 , at least one lamp support structure 22 , at least one fixing piece 230 , at least one buffer piece 240 and a plurality of lamps 25 years old. The bottom plate 210 has a plurality of first openings 21〇a, and the lamp support structure 22 is disposed on the first openings 210a. In more detail, the lamp support structure 22 includes a base 222, a plurality of lamp clip heads 224 and a plurality of engaging portions 226, wherein the base 222 is disposed on the bottom plate 210, and the lamp clip heads 224 It is disposed on the base 222. In addition, the engaging portions 226 are disposed under the base 210 and are engaged with the first openings 210a (as shown in FIG. 2B). In other words, the engaging portion 226 and the lamp holder head 224 are respectively located on opposite surfaces of the base 222, and the engaging portions 226 pass through the first opening 210a. The fixing piece 230 is disposed under the bottom plate 222, and the fixing piece 230 has a plurality of second openings 230a of the M320085 0610122UTW 21820 twf.doc/n, and the engaging portions 220 are further disposed on the second openings 230a (as shown in FIG. 2B).
