A direct type backlight module ( 200 ) includes a substrate ( 231 ), a diffusion sheet ( 24 ) disposed above the substrate, a plurality of spacers ( 21 ) and a plurality of light sources ( 22 ). The spacers are disposed between the substrate and the diffusion sheet. Each spacer includes a bottom surface ( 211 ) contacting with the substrate. A groove ( 2114 ) is defined in the bottom surface, and a light incident surface ( 2112 ) is defined on inner surface of the groove. A pair of wings is disposed on two sides of the bottom surface for supporting the diffusion sheet. Each wing includes an outer side surface and an inner side surface, and a transflective film is formed on the inner side surfaces of the wing. The light sources are respectively disposed in the grooves.
