| 发明名称 | White light emitting diode and liquid crystal display including the same | ||
| 摘要 | 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*ab±2ΔE*ab) locus from the constant hue locus of each of sRGB color coordinates, or within a chrominance error range (±4ΔE*ab±2ΔE*ab) locus from the constant hue locus of each of AdobeRGB color coordinates. | ||

| 主权项 | 1. A back light unit comprising: a light emitting diode light source; and a light conversion layer which converts incident light from the light emitting diode light source into white light, wherein at least two of red, green and blue color coordinate loci of the white light are within a chrominance error range (±4ΔE*ab) locus from the constant hue locus of sRGB color coordinates, or within a chrominance error range (±4ΔE*ab) locus from the constant hue locus of AdobeRGB color coordinates, wherein the light conversion layer comprises semiconductor nanocrystals. | ||
