Abstract
The present invention discloses a backlight module, which includes a light source, a PCB, and a backplane. The PCB forms a bend. The light source is fixed on the PCB that has the bend. The PCB is fixedly connected to the backplane to conduct away heat generated by the light source. The present invention also discloses a liquid crystal display device that includes the above structure of backlight module. Practicing the backlight module and the liquid crystal display device of the present invention enables optimization of a heat dissipation path within the backlight module to achieve ultra-slimming of side frame of the backlight module.
