Abstract:
A light-emitting device comprises a substrate, and a light-emitting structure formed on the substrate. The light-emitting structure comprises a first active layer emitting the light with a first wavelength, and a second active layer emitting the light with a second wavelength. The light-emitting structure is formed by the first active layer and the second active layer stacked alternately.
