A backlight module is disclosed, which includes plural light sources, a light guide plate, a light scattering device, a high-reflectance microstructure formed on the light guide plate, and a high-diffusion microstructure formed on the light guide plate. The light guide plate has a first surface and a second surface opposite to the first surface. The first surface faces the light sources. The light scattering device is disposed between the light sources and the light guide plate. The high-reflectance microstructure is formed on the second surface. The high-diffusion microstructure is formed on or indented inwardly from the first surface.
