In this embodiment, the inner surface 110 of the accommodating space 108 may be curved, but not limited thereto. In another embodiment, the inner surface 110 of the accommodating space 108 may be tapered or square. It should be noted that the shape of the inner surface 110 of the accommodating space 108 can be designed according to actual light requirements, and the invention is not limited thereto.
At least one of the substrate 102 and the light guide 106 has a first bonding structure 112 and a second bonding structure 114. Therefore, the first combining structure 112 of one of the light source modules 100 can be combined with the second combining structure 114 of another one of the light source modules 100, so that the light source modules 100 can be adjacent to each other to form the light source assembly 10.
As shown in fig. 2, in this embodiment, the substrate 102 may have two first combining structures 112 and two second combining structures 114, and the light guide 106 may also have two first combining structures 112 and two second combining structures 114, wherein the positions of the first combining structures 112 and the second combining structures 114 of the substrate 102 correspond to the positions of the first combining structures 112 and the second combining structures 114 of the light guide 106.

As shown in fig. 10 and 11, the light source assembly 10 'may be disposed on the plate 12'. In this embodiment, at least one of the substrate 102 and the light guide 106 of the light source module 100 may have a first positioning structure. As shown in fig. 11, the substrate 102 of the light source module 100 has a first positioning structure 124. In addition, the plate member 12' may have a plurality of second locating structures 126. In this embodiment, one of the first positioning structure 124 and the second positioning structure 126 may be a hook, and the other of the first positioning structure 124 and the second positioning structure 126 may be a fastening hole. As shown in fig. 11, the first positioning structure 124 can be a hook, and the second positioning structure 126 can be a hole. Therefore, when the light source assembly 10 'is disposed on the board 12', the first positioning structure 124 and the second positioning structure 126 can be engaged with each other in a snap-fit manner to position the light source assembly 10 'on the board 12'.
Referring to fig. 12, fig. 12 is a cross-sectional view of a light source assembly 10 'and a plate 12' according to an embodiment of the invention.

As shown in fig. 12, the first positioning structure 124 may be a magnetically permeable material, and the second positioning structure 126 may be a magnet. Therefore, when the light source assembly 10 'is disposed on the plate 12', the first positioning structure 124 and the second positioning structure 126 can be magnetically coupled to each other to position the light source assembly 10 'on the plate 12'.
In another embodiment, the light source assembly 10 'can also be adhered to the plate 12' by a double-sided adhesive. In this case, the first positioning structure 124 and the second positioning structure 126 can be omitted.
In summary, the light source module of the present invention is composed of a substrate, a light emitting unit and a light guide member, and the light source module has a combination structure capable of combining with other light source modules. Therefore, the invention can combine a plurality of light source modules into a planar light source combination.

When the light source assembly is used as a direct type backlight module, the display device is beneficial to thin design.
