An exemplary liquid crystal display (200) includes a liquid crystal panel (210) and a backlight module (220). The backlight module is positioned for illuminating the liquid crystal panel, and includes a light source (222) and at least one optical member (221). The at least one optical member includes absorbing material for absorbing light beams having wavelength more than 700 nanometers, such that when light beams provided by the light source transmit through the at least one optical member, at least some of the light beams having wavelengths more than 700 nanometers are absorbed by the absorbing material.
