In the second embodiment, referring to fig. 6, 7 and 8, a transition arc surface is disposed at a connection position of each of the second extending portions 31 and the periphery of the reflective sheet 30. With such an arrangement, since each second extending portion 31 is disposed opposite to one first extending portion 11, two adjacent second extending portions 31 and the periphery of the reflection sheet 30 enclose to form a second groove; the end of each second extending portion 31 adjacent to the second groove is in arc transition, that is, the joint between the second extending portion 31 and the reflective sheet 30 is an arc surface, that is, the second extending portion 31 does not form a sharp corner, so that the light emitting effect of the whole backlight module is not affected.
In an embodiment, referring to fig. 6, 7 and 8, the shape of the second extension 31 is the same as the shape of the first extension 11.
