Abstract
An exemplary backlight module (20) includes a light guide plate (22) having a light incident surface (224), a plurality of light sources (23) adjacent to the light incident surface, a frame (24) for receiving the light sources and the light guide plate, and a colored reflective structure (220) disposed in the frame. Some of the light beams emitting from the light sources are transmitted to the colored reflective structure and converted to reflected light beams having a corresponding color. The reflected light beams further mix with light beams emitting from the light sources and generate light beams in desired color system. A liquid crystal display (200) using the backlight module is also provided.
