<p>A backlight module and a liquid crystal display device. The backlight module comprises a back panel (210), a heat dissipation substrate (230) and a light source (240). The back panel (210) is provided with a substrate (212); the heat dissipation substrate (230) comprises a heat dissipation part (231) and a fixed part (232) which is connected to the heat dissipation part (231); the light source (240) is fixed to the heat dissipation part (231). The fixed part (232) is fixed to the lower side of the substrate (212), and a front frame (250) is fixed to the heat dissipation part (231). When a light source of a liquid crystal display device needs to be replaced, only the heat dissipation substrate and the light source need to be removed without removing other components of the liquid crystal display device. Therefore, the operation of replacing the light source may not have any effect on other elements, thereby simplifying the operation process of replacing the light source, and improving the product yield of liquid crystal display devices.</p> |
