Abstract: A backlight module and a liquid crystal display device are provided. An outer wall located on the light incident side of the plastic frame is arc-shaped, so a graphite sheet attached to a flexible printed circuit board can be attached to a backside of a reflector plate along the arc-shaped outer wall, thereby increasing the size of the graphite and enhancing heat dissipation efficiency of the backlight module.
