Abstract: A backlight module and a liquid crystal display are provided. The backlight module has a substrate, a plurality of soldering pads, and a reflective pattern layer. The soldering pads are distributed on the substrate and each of the soldering pads has a soldering pad size. The reflective pattern layer covers the soldering pads and the substrate. The reflective pattern layer has openings, positions of the openings correspond to positions of the soldering pads, each of the openings has an opening size, and the opening size is smaller than the corresponding soldering pad size. The backlight module is provided with the openings in the reflective pattern corresponding to the positions of the soldering pads, and the opening size of the openings is smaller than the soldering pad size of the soldering pads, thereby increasing a ratio of the reflective pattern layer to the substrate.
