Abstract

A LCD includes a liquid crystal panel, a backlight module opposite to the liquid crystal panel, at least one quantum rod film and at least one wavelength film. The quantum rod film is between the liquid crystal panel and the backlight module, and the wavelength film is between the quantum rod film and the liquid crystal panel. Light beams generated by the backlight module pass through the quantum rod film and the wavelength film in sequence to arrive the liquid crystal panel. By adopting the quantum rod film, the saturation of the LCD may be greatly enhanced.
