A backlight module (1) includes a light source (92), a light guide plate (80), and a frame (60). The frame contains the light source and the light guide plate. The frame includes a base plate (65) defining a transflective region (651) and a plurality of holes (652) defined in the transflective region. A portion of light beams from the light source is reflected by the transflective region out one main face of the backlight module, and a remainder of the light beams passes through the transflective region to emit from another main face of the backlight module. The backlight module and frame provide a double-sided emitting structure for a double-sided LCD. This avoids the need for an expensive transflector.
