    Abstract: An exemplary light emitting diode includes a substrate; a first light emitting cell and a second light emitting cell disposed over the substrate and separated from each other; and an interconnection electrically connecting the first light emitting cell to the second light emitting cell. Each of the first and second light emitting cells includes a first conductive-type semiconductor layer, a second conductive-type semiconductor layer disposed over the first conductive-type semiconductor layer, and an active layer disposed between the first conductive-type semiconductor layer and the second conductive-type semiconductor layer. At least one of the first light emitting cell and the second light emitting cell includes a side surface inclined with respect to the substrate. The side surface includes a first inclined portion forming an acute angle with respect to the substrate, a second inclined portion forming an obtuse angle with respect to the substrate, and an inclination discontinuity section.
