Abstract

Provided is a light-emitting device including an epitaxial structure that includes first, second, and third light-emitting structures having widths increasing in a vertical direction and each including a p-type semiconductor layer, an active layer, and an n-type semiconductor layer, first, second, and third p-electrodes, at least one of which has a conductive via structure, are on the epitaxial structure and respectively contact the p-type semiconductor layers of the first, second, and third light-emitting structures, an n-common electrode including an n-common portion on the epitaxial structure, and n-electrode portions extending from the n-common portion and respectively contacting side surfaces of the n-type semiconductor layers of the first, second, and third light-emitting structures, and a separation structure separating side surfaces of the p-type semiconductor layers and the active layers of the first, second, and third light-emitting structures from the n-common electrode.
