Abstract: The present invention provides a backlight module and a liquid crystal display device. The backlight module of the present invention includes an upper brightness enhancement film (7), which includes a central zone (71) and a lens zone (72) located between the central zone (71) and a mold frame (1). The upper brightness enhancement film (7) includes a prism structure formed on an upper surface of the central zone (71); and the upper brightness enhancement film (7) includes a lens structure formed on an upper surface of the lens zone (72). The lens structure includes a plurality of concave surfaces (721) arranged in sequence in a side-by-side manner from an edge of the upper brightness enhancement film (7) toward interior thereof. The prism structure and the lens structure of the upper brightness enhancement film (7) are integrally formed together. The lens structure of the upper brightness enhancement film (7) helps diverge light projecting outward so as to have a part of the light extending over and covering a portion of an area shielded by the light-shielding tape (8), expanding a view area of the backlight module to thereby achieving a visual effect of narrowing bezel. Further, the manufacturing process is simplified, the manufacturing cost is reduced, and product yield is increased.
