Abstract
An exemplary backlight module includes a back plate, a side bar received in the back plate, and an optical film assembly received in the back plate. The side bar includes a main body and an elastic member extending from the main body. The elastic member and the main body cooperatively define a receiving groove therebetween. The optical film assembly is received in the back plate, and has an edge portion elastically received in the receiving groove. A liquid crystal display employing the backlight module is also provided.
