LIGHT-EMITTING DEVICE AND LIGHT-EMITTING DEVICE ARRAY INCLUDING THE SAME

A light-emitting device include an emission layer configured to emit white light, and a reflective layer at least partially surrounding side surfaces of the emission layer, where the emission layer includes a first conductivity-type semiconductor layer, a second conductivity-type semiconductor layer on the first conductivity-type semiconductor layer, a first active layer between the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer, the first active layer configured to emit blue light, and a second active layer between the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer, the second active layer configured to emit yellow light.
