Abstract: The present application discloses a light-emitting element comprising a semiconductor light-emitting stack emitting a first light which has a first color coordinate, a first wavelength conversion material on the semiconductor light-emitting stack converting the first light to emit a second light, and a second wavelength conversion material on the first wavelength conversion material converting the second light to emit a third light. The first light and the second light are mixed to be a fourth light having a second color coordinate. The third light and the fourth light are mixed to be a fifth light having a third color coordinate, and the second color coordinate locates at the top right of the first color coordinate and the third color coordinate locates at the top right of the second color coordinate.
