Patent ID: 7724320

Claim:
A liquid crystal display, comprising: a liquid crystal panel; and a backlight module positioned for illuminating the liquid crystal panel, the backlight module comprising a light source and at least one optical member; wherein the at least one optical member comprises a light guide plate, the light guide plate comprises a plurality of dots disposed thereon, a plurality of carbon nanotubes are embedded in the plurality of dots, and the carbon nanotubes are configured for absorbing light beams having wavelengths more than 700 nanometers, such that when light beams provided by the light source transmit through the light guide plate, at least some of the light beams having wavelengths more than 700 nanometers are absorbed by the carbon nanotubes, and the light beams that are not absorbed by the carbon nanotubes, together with the light beams not transmitted to the plurality of dots, are guided by the light guide plate to emit to the liquid crystal panel.
