BRIEF DESCRIPTION OF THE DRAWINGS The spirit of the present invention will be clearly described in the following description and detailed description of the present invention. And modifications may be made without departing from the spirit and scope of the invention. Referring to Figure 1A, there is shown a schematic view of a first embodiment of a backlight module of the present invention. The backlight module 100 includes a frame 11 , a light source 12 , a fixing member 130 disposed on the frame 110 , a light guide plate 140 , and a support rib 150 . The frame 110 includes a bottom surface 112 and a sidewall 114 perpendicular to each other. The light source 120 is disposed within the frame 11 〇 and adjacent to the sidewall 114. The fixing member 130 is disposed on the frame 11 , and one end of the fixing member 130 is connected to the bottom surface 112. The fixing member 130 has a locking portion 132 at one end of the bottom surface 112. The locking portion 132 is configured to fasten the light source 120. On the frame 110. The support rib 150 is coupled to the bottom surface 112, and the support rib 150 extends toward the light guide plate 140. The light guide plate 140 is disposed on the support rib 150 such that the support rib 150 supports the light guide plate 140. The light source 120 includes a substrate 122 and a light emitting element 124. The substrate 122 includes a first surface 121 and a second surface 123. The light emitting element 124 is disposed on the first surface 121 of the substrate 122 and has a space between adjacent light emitting elements 124. In an embodiment of the invention, the light emitting element 124 can be a light emitting diode. The fixing member 130 is preferably disposed between the adjacent two light emitting elements 124 such that the light emitted by the light emitting element 124 is not blocked by the fixing member 130. The number of the fixing members no may be a plurality of, 201213967 and the preferred distribution is an even distribution, such that a fixing member 130' is disposed between each adjacent two light-emitting elements 124 by the fastening portion on the fixing member 130. The light source 120 is fixed to the frame 110. Alternatively, the number of the fixing members 130 may be smaller than the number of the spaces between the light-emitting elements 124 as long as the number of the fixing members 130 is sufficient to buckle the light-emitting source 120 on the frame 11''. The support rib 150 is substantially L-shaped in shape, and one end of the support rib 150 is coupled to the bottom surface 112, and the other end of the support rib 150 is bent to extend toward the light guide plate 140 to support the light guide plate 140. The support rib 150 includes an associated limiting portion 152 and a support portion 154, wherein the limiting portion 152 is coupled to the bottom surface 112, and the limiting portion 152 is parallel to the side wall 114. The support portion 154 extends from the limiting portion 152 and is bent toward the light guide plate 140 such that the support portion 154 is parallel to the bottom surface 112 to support the light guide plate 140. The position of the limiting portion 152 is preferably disposed between the adjacent two light-emitting elements 124 such that the light emitted by the light-emitting element 124 is not blocked by the limiting portion 152. In the embodiment of the present invention, the material of the frame body 110, the fixing member 13A, and the supporting rib 150 may be elastic plastic, and the frame body 11 and the fixing member 130 and the supporting rib 150 are preferably integrally formed. When the light source 120 is assembled, the elastic fixing member 130 can be pulled, so that the fixing member 130 is slightly deformed, so that the light source 120 can be caught in the space between the supporting rib 15 and the side wall 114. The latching portion 132 of the fixing member 130 can hook the bottom of the substrate 122 of the light source 120 to prevent the light source 120 from falling off, so that the light source 120 is held between the fixing member 130 and the sidewall 114. The fixing member 13 is in contact with the first surface 121 of the substrate 122 such that the fixing member 13 is hooked to the substrate 122 from the inside to the outside. The spacing between the fixture 130 and the sidewall 114 is substantially the same as the thickness of the substrate 122, thereby limiting the displacement of the illumination source 12 in the front and rear 201213967 directions. Compared with the conventional method of using the double-sided tape to attach the light source 12 〇 to the frame 110, the present invention only needs to pull the elastic fixing member 130 to fix the light source 120 by the fixing member 13 〇 On the body 11 (), assembly is more convenient. In addition, when double-sided tape is conventionally used, if it is accidentally assembled or if parts need to be replaced, it may cause heavy work due to the stickiness of the double-sided tape. The invention fixes the light source 120 by the snapping method, and can effectively solve the problem that the heavy work is not easy. The fixture 130 can be in contact with the substrate 122 to position the substrate 122. In this embodiment, the surface of the substrate 122 is a flat surface, and the fixing member 13 is in contact with the surface of the substrate 122 to achieve the effect of positioning the substrate 122. Alternatively, the substrate 122 may have a recess (not shown), and the fixing member 13 can be engaged with the recess to achieve a better positioning effect. The bottom surface 112 of the frame body 110 further defines a rib 116. The rib 116 is located above the support rib 150, and an accommodation space is formed between the rib 1616 and the support rib 150 to place the light guide plate 140. The rib 116 is further used to support a display panel (not shown). The light guide plate 140 is placed on the support rib 150, and the light guide plate 140 is further sandwiched between the rib 116 and the support rib 150 to limit the displacement of the light guide plate 140 in the z-axis direction.
