A light emitting device includes a light emitting structure including a support structure including a first bulk electrode a second bulk electrode disposed on and electrically connected to the first electrode and the second electrode, respectively. A substrate is disposed adjacent to the support structure, wherein each of the first and second bulk electrodes includes an upper region and a lower region with the upper regions of the first and second bulk electrodes being separated from each other by a first distance. The substrate includes a first interconnection portion and a second interconnection portion electrically connected to the first bulk electrode and the second bulk electrode, respectively, and separated from each other by a second distance. The second distance is greater than the first distance.
