Abstract
A light-emitting device may include separate, first and second light-emitting structures that are isolated from direct contact with each other on a phototransmissive substrate. Each light-emitting structure may include a first conductivity-type semiconductor layer, an active layer on the first conductivity-type semiconductor layer, and a second conductivity-type semiconductor layer on the active layer. The first and second light-emitting structures may be electrically connected to each other. An inter-structure conductive layer may electrically interconnect the first conductivity-type semiconductor layer of the first light-emitting structure to the second conductivity-type semiconductor layer of the second light-emitting structure. The second light-emitting structure may include a finger structure extending from an outer edge of the second light-emitting structure toward an interior of the second light-emitting structure. The second light-emitting structure may include island structures that are isolated from direct contact with each other and a bridge structure between adjacent island structures.
