Abstract
A white light emitting diode includes a blue light emitting diode ('LED') light source, and a light conversion layer which converts incident light from the blue LED light source into white light. The light conversion layer includes a green light emitting semiconductor nanocrystal and a red light emitting semiconductor nanocrystal. The white light emitting diode has a red, green and blue color ('RGB') color locus which is within a chrominance error range (±4ΔE*) locus from the constant hue locus of each of sRGB color coordinates, or within a chrominance error range (±4ΔE*) locus from the constant hue locus of each of AdobeRGB color coordinates.
