A backlight module ( 100 ) includes a light guide plate ( 56 ), a bottom tray ( 50 ) having a spring finger ( 506 ), a radiation element ( 59 ) disposed adjacent to the light guide plate, and a frame ( 55 ) receiving the light guide plate and the radiation element. The light guide plate includes a light incident surface ( 560 ), and a side surface ( 564 ) opposite to the light incident surface. An ear ( 566 ) is formed on the side surface, and the spring finger presses the light guide plate toward the radiation element. A distance between the radiation element and the light incident surface is thereby decreased or even eliminated. This enables the backlight module to provide improved brightness and uniformity of emitting luminance.
