Abstract
A backlight module (2) includes a frame (20), a light source (22) and a light guide plate(21). The light guide plate has a light-emitting surface (211), an incident surface (212), and a bottom surface. The frame accommodates the light guide plate and the light source. The light guide plate is integrated with the frame, because it is made from ultraviolet curable glues filled into the frame. The backlight module is simple, compact, and inexpensive to make.
