Classification: CPC H | IPC H

Claim 0:
1. A light emitting device comprising:
a plurality of light emitters comprising:
a first light emitter including a first-type semiconductor layer, a first active layer, and a second-type semiconductor layer;
a second light emitter disposed near the first light emitter, and including a first-type semiconductor layer, a second active layer, and a second-type semiconductor layer; and
a third light emitter disposed near the second light emitter, and including a first-type semiconductor layer, a third active layer, and a second-type semiconductor layer;

a first pad electrically coupled with the second-type semiconductor layer of the first light emitter;
a second pad electrically coupled with the second-type semiconductor layer of the second light emitter;
a third pad electrically coupled with the second-type semiconductor layer of the third light emitter; and
a common pad electrically coupled with the first-type semiconductor layer of the first, second, and third light emitters,
wherein, in a current density per light emitter of about 20 A/cm2, each of the first, second, and third light emitters is configured to emit light having a peak wavelength different from each other, and one of the first, second, and third light emitters that is configured to emit light having the longest peak wavelength has a largest normalized external quantum efficiency than those of the remaining ones of the first, second, and third light emitters.
