摘要:
A light-emitting chip includes a light-emitting part, a first color-converting part and a second color-converting part. The light-emitting part includes a first electrode and a second electrode, and generates first light of a first wavelength. The first color-converting part is formed on a light-emitting surface of the light-emitting part. The first color-converting part converts at least a portion of the first light into second light of a second wavelength. The second color-converting part is formed on the first color-converting part. The second color-converting part converts at least a portion of the first light into third light of a third wavelength that is shorter than the second wavelength. Thus, a fluorescent substance of a long wavelength and a fluorescent substance of a short wavelength are sequentially formed on a light-emitting surface of a light-emitting part, so that the color reproducibility of a light-emitting chip may be enhanced.
