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.
