The present invention provides a white light emitting diode (LED) is applied to colorful LCD as backlight source with high color saturation. It is different from traditional two-wavelength type white light LED that is coated a blue LED chip with yellow phosphor and only provides 50~60% NTSC. In this invention, white light LED generates three-wavelength by coating a blue LED chip with green and red phosphors. It can provide more than 80% NTSC and is suitable for backlight of LCD TV and computer monitor.
