Abstract
A backlight module includes a laser light source and a light guide plate. The light source locates beside a side surface of the light guide plate. The light guide plate comprises a plurality of transflective films arranged along a direction in alignment the laser light source. When the light from the laser light source emits to the transflective films, a part of the light passes through the transflective films and transmits along a same direction, and another part of the light is reflected by the transflective films and emits into a light diffusion plate. The light beams reflected by the transflective films and into the light diffusion plate have the same intensity.
