Abstract: A light-emitting diode includes a first electrode part, a second electrode part disposed on the first electrode part, and a semiconductor junction structure disposed between the first electrode part and the second electrode part. The semiconductor junction structure may include a first semiconductor layer, a second semiconductor layer, a third semiconductor layer, an optical layer, and an active layer. Any one of the optical layer and the active layer may be disposed between the first semiconductor layer and the second semiconductor layer, and another one of the optical layer and the active layer may be disposed between the second semiconductor layer and the third semiconductor layer. The optical layer may include a porous layer and a non-porous layer disposed on the porous layer, and in a direction perpendicular to the thickness direction, a first width of the porous layer may be greater than a second width of the non-porous layer.
