Abstract: A three-dimensional (3D) light-emitting device may include a plurality of 3D light-emitting structures formed apart from one another, each 3D light-emitting structure including: a semiconductor core vertically grown on one surface and doped in a first conductive type; an active layer formed so as to surround a surface of the semiconductor core; and a first semiconductor layer formed so as to surround a surface of the active layer and doped in a second conductive type. The 3D light-emitting device may include: a first porous insulating layer formed between lower corner portions of the 3D light-emitting structures so as to expose upper end portions of the 3D light-emitting structures; a first electrode electrically connected to the first semiconductor layer; and a second electrode electrically connected to the semiconductor core.
