1. A semiconductor light emitting device comprising:

  • a semiconductor light emitting laminate including a first conductive semiconductor layer, a second conductive semiconductor layer, and an active layer interposed therebetween;

    a first electrode having at least one bonding pad formed on a portion of an upper surface of the first conductive semiconductor layer;

    a second electrode having an ohmic contact layer formed on the second conductive semiconductor layer; and

    a current blocking layer between the second conductive semiconductor layer and the ohmic contact layer having a plurality of patterns formed thereon, the plurality of patterns being arrayed such that intervals between patterns adjacent to a region overlapped with the bonding pad are smaller than an interval between patterns of another regions.
