A surface light source assembly is disclosed. The surface light source assembly includes a light guide plate (1), a reflective sheet (2), a light diffuser sheet (3) and a transparent cover (4) arranged in front of the light diffuser sheet (3), an insert-nut (81) embedded in the light guide plate (1), and a supporting frame (5) having a vertical plate (52) and a screw movable hole (53) arranged on the vertical plate (52). In the insert-nut (81), a screw (8) is screwed from an end holding frame (7) overlapped on both ends of the supporting frame (5) and arranged in both ends of the light guide plate (1) via the screw movable hole (53). The screw (8) can be moved in the screw movable hole (53) depending on a heat expansion and contraction of the light guide plate (1). |
