Abstract
The invention provides a backlight module and an LCD device including the backlight module. The backlight module includes an LGP, a lightbar optically coupled with the LGP, and an outer frame. The lightbar is arranged on the outer frame from the inner side of the backlight module. In the invention, because the lightbar is arranged on the outer frame of the backlight module, the lightbar can directly exchange heat with the outside air via the outer frame to dissipate heat; because the lightbar is directly arranged on the outer frame, the heat conduction path is shortened to a great extent. Thus, the heat emitted by the lightbar can be dissipated via the outer frame in time; the inside temperature of the backlight module is reduced, the stability and the service life of the components in the backlight module are increased, and the phenomenon that the stability of the LCD panel is affected by overhigh temperature is avoided.
