  • Ultraviolet light emitting device
    Patent number: 9786814
    Abstract: The ultraviolet light emitting device includes a substrate; a light emitting structure on the substrate, and including a plurality of compound semiconductors, each including at least a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer; a first electrode layer on the first conductive semiconductor layer; and a second electrode layer on the second conductive semiconductor layer. The first electrode layer is spaced apart from a side surface of the active layer, and is provided along a peripheral portion of the active layer. At least one of the first and second electrode layers is a reflective layer.
