Abstract: The present invention teaches a backlight module and the LCD device. The backlight module includes a light guide plate and a light source located at a distance to a side of the light guide plate. The light source includes a substrate, multiple LED chips disposed on the substrate, multiple primary lenses disposed on the substrate corresponding to the LED chips, and multiple condenser lenses disposed on the substrate corresponding to the primary lenses. Each primary lens is disposed correspondingly to a LED chip, focuses light from the LED chip, and prevents the light emission face of the LED chip from being higher above the light guide plate, thereby enhancing the light coupling efficiency and reducing leakage of the backlight module. Each condenser lens is disposed correspondingly to a primary lens to further narrow light emission angle of the LED chip, enhancing light utilization efficiency.
