A backlight module includes a frame, a light guide plate, a FPCB and a plurality of point light sources. The light guide plate has a light incident surface. The point light sources are electrically connected with one surface of the FPCB, each point light source having an emitting surface. The frame includes a plurality of connecting sidewalls encircling the light guide plate. An inner surface of the sidewall facing the light incident surface defines a plurality of elastic members thereon according to the point light sources. Each elastic member pushes the corresponding point light source towards the light guide plate, so as to have the final position of the emitting surface of each point light source come in contact with the light incident surface. The present backlight module has a highly light energy utilization rate.
