Abstract
A white light emitting diode and a liquid crystal display device that realizes images using the white light are provided. The white light emitting diode includes a blue light emitting diode ('LED') light source, and a light conversion layer which converts incident light from the LED light source into white light. The light conversion layer includes green light emitting semiconductor nanocrystal and red light emitting semiconductor nanocrystal. A light emitting peak wavelength of the green light emitting semiconductor nanocrystal is about 520 nanometer (nm) or more, a light emitting peak wavelength of the red semiconductor nanocrystal is about 610 nanometer (nm) or more, and full width at half maximums (FWHMs) of light emitting peaks of the green and red light emitting semiconductor nanocrystals are about 45 nanometer (nm) or less.
