Abstract
A fixing apparatus, applied to a diffuser plate of a backlight unit (BLU), includes a fixing groove and a positioning piece. The fixing groove is formed at the frame and symmetrically related to one end of a centrosymmetric line of a diffuser plate. A first pair of edges are set at two sides of the centrosymmetric line. A third edge connects the first pair of edges cutting across the centrosymmetric line. The positioning piece is located within the fixing groove. The positioning piece is separated from the first pair of edges of the fixing groove at a first distance, and separated from the third edge of the fixing groove at a second distance, wherein the first distance is smaller than the second distance.
