Fig. 8 is a schematic view of a microstructure according to a fifth embodiment of the present invention. As shown in Fig. 8, the second microstructures 51 2 are a plurality of elliptical particles which are obliquely and regularly arranged. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 9 is a schematic view of a microstructure according to a sixth embodiment of the present invention. As shown in Fig. 9, the second microstructures 612 are tapered particles; here, the tapered particles of the present pattern are quadrangular pyramids. As described above, the fourth embodiment is a different embodiment of the third microstructure. However, those skilled in the art can of course design a similar wheel gallery into the shape of the first microstructure. Thus, the light guide plate of the present invention can have more structural changes, and the diversity and flexibility in use can be increased. Referring to Fig. 10, Fig. 1A is a schematic view of a backlight module according to a seventh embodiment of the present invention. As shown in FIG. ,, the alignment scales 715 correspond to the four sides of the diffusion film 74 and the brightness enhancement film 76. When the diffusion film 74 and the brightness enhancement film 76 are assembled and coupled with the light guide plate 71, the sides of the diffusion film 74 and the brightness enhancement film 76 can be aimed at aligning the alignment scales 715. Therefore, the diffusion film 74 and the brightness enhancement film 76 can be combined with the light guide plate 71 without any error by the marking of the four sets of alignment scales 715. In summary, the light guide plate of the present invention can solve the problem of correcting the 'alignment requirement at the time of manufacture', so that the skew, the deviation, and the misalignment are no longer generated; and the backlight module of the light guide plate of the present invention is used to assemble the diffusion film. When the film is brightened, it can also achieve the purpose of rapid bonding and assembly, which maximizes the optical effect; it is very practical. 100110919 Form No. A0101 Page 11 of 26 1002018309-0 201239424 [0033] The present invention is described by way of example only, and is not intended to limit the scope of the claimed invention.
