Abstract
The invention provides a backlight module and a LCD device. The backlight module includes a side frame, and a rear panel; the rear panel is provided with a side wall fixedly matched with the side frame, the side wall of the rear panel is provided with a light source, and a gap is reserved between the top of the side wall and the side frame. The invention can effectively block the path that the heat at the side of the light source is transferred to the LCD panel, and can effectively prevent the risk of the liquid crystal liquefaction of the LCD panel, thereby improving the optical display taste of the LCD panel.
