An exemplary backlight module ( 2 ) includes a plurality of light sources ( 30 ), a diffusion sheet ( 20 ), and a reflective plate ( 40 ). The light sources are disposed between the diffusion sheet and the reflective plate, and the reflective plate includes a plurality of elongate bumps ( 41 ) thereon, integrally formed therewith. The bumps face toward the diffusion sheet, and each of the bumps is located generally midway between two corresponding adjacent of the light sources. Each bump is located midway between two adjacent light sources for concentrating and guiding reflected light beams toward a corresponding area of the diffusion sheet above the bump. Accordingly, a light intensity distribution in the area of the diffusion sheet above the bump is closer to the same as a light intensity distribution in each of areas of the diffusion sheet above the two adjacent light sources.
