BACKLIGHT MODULE

摘要

A backlight module comprises a light guide plate, a plurality of light guide portions, and a plurality of light sources. Each light guide portion is wedge-shaped. Each light guide portion comprises a first side surface and a second side surface opposite to the first side surface. The second side surface is in contact with the light guide plate. Along a direction perpendicular to the light guide plate, a thickness of the first side surface is greater than a thickness of the second side surface. A receiving groove is defined on the first side surface. Each light source is received in a corresponding one of the receiving grooves.
