  • Patent number: 9548422
    Abstract: A semiconductor light emitting device includes a light emitting structure and first and second electrodes. The light emitting structure includes first and second conductivity type semiconductor layers and an active layer interposed therebetween. The first and second electrodes are electrically connected to the first and second conductivity type semiconductor layers. The second electrode includes a current blocking layer, a reflective part disposed on the current blocking layer, a transparent electrode layer disposed on the second conductivity type semiconductor layer, a pad electrode part disposed within a region of the current blocking layer, and at least one finger electrode part disposed at least in part on the transparent electrode layer. The transparent electrode layer can be spaced apart from the reflective part, and have an opening surrounding the reflective part. In some examples, the transparent electrode layer can further be spaced apart from the current blocking layer.
