A liquid crystal display (LCD) structure is provided. The LCD structure is that a backlight module having ventilated thin film with high reflective material combines with a liquid crystal panel. The backlight module includes a bottom and at least a ventilated thin film with high reflective material. The side plates of the bottom have at least an opening, and the ventilated thin film with high reflective material is disposed at the openings. The backlight module, making use of the openings at the bottom of the backplate and the ventilated thin film with high reflected material, can improve the heat-dissipating mechanism of the backlight module, thereby, can effectively lower the temperature of the backlight module.
