The patent application relates to a backlight module and a liquid crystal display. Such backlight module includes a front casing, a back casing and a light source. The front casing includes a first clamping part and a second clamping part externally and vertically extended from the first clamping part. The second clamping part is fixedly connected with the back casing. The light source is positioned between the first clamping part and the back casing, and the back side of the light source is contacted with the inner side face of the second clamping part. The inside of the second clamping part corresponding to the back of the light source is provided with a fin heat-dissipation structure. The patent application directly fixes an LED light source on the front casing of the all-in-one machine of the liquid crystal display, which simplifies the heat transmission way, reduces the thermal contact resistance and increases the effective heat-dissipation area of the front casing Thereby, the heat caused by the LED light source can be synchronously transmitted to the front casing and to the back casing. Besides, the utility model installs a fin heat-dissipation structure on the front casing corresponding to the back of the LED light source, which can improve the heat-dissipation efficiency to a large extent. Moreover, the utility model installs a honeycomb-structured buffer component on the front casing where the liquid crystal panel is clamped for enhancing the buffering performance of the liquid crystal panel.
