Abstract
A backlight module is disclosed, which includes a light source; a light guide plate disposed on the light source. The light guide plate has a bottom surface receiving light from the light source and a front surface emitting light, and the front surface is perpendicular to the bottom surface. The light guide plate has a first notch placed on a top corner; and a plastic frame circumventing the light source and the light guide plate. The plastic frame comprises a portion starting from a frame light incident section near the light source and ending at a first frame light emitting section near the first notch, and the portion is light transparent to pass light from the light source, and has a reflective coating.
