Embodiments provide a light emitting diode and a method of fabricating the same. The light emitting diode includes a base, a light emitting structure disposed on the base, at least one first electrode disposed on the light emitting structure; and a second electrode disposed under the light emitting structure, wherein at least a portion of the second electrode is covered by the base and the base includes a supporting insulator and at least one bulk electrode embedded in the supporting insulator and electrically connected to the light emitting structure, and a surface of the at least one bulk electrode is exposed through the supporting insulator. The light emitting diode has excellent reliability and efficiency.
