Abstract
A backlight module is provided, including a back plate, a diffusion plate, multiple lighting bars mounted on the back plate and at least one lighting module mounted on each of the lighting bars, where each of the lighting modules has an LED forward light source and at least one pair of LED non-forward light sources, and the pair of LED non-forward light sources is mounted on the side of the LED forward light source, and light emitted from the LED forward light source and light emitted from each of the pair of LED light sources are spliced together to form a diffusing light shape. Therefore, the backlight module of the present invention has reduced lighting bars to decrease the weight, volume and cost of the whole backlight module and liquid-crystal display device, and overcome the problems of non-uniform brightness of conventional backlight modules.
