1. A light emitting diode (LED) comprising:

  • a first conductive type semiconductor layer;

    an active layer positioned over the first conductive type semiconductor layer;

    a second conductive type semiconductor layer positioned over the active layer; and

    a defect blocking layer comprising a masking region to cover at least a part of the top surface of the second conductive semiconductor layer and an opening region to partially expose the top surface of the second conductive type semiconductor layer,wherein the active layer and the second conductive type semiconductor layer are disposed to expose a part of the first conductive type semiconductor layer, andwherein the defect blocking layer comprises a first region and a second region surrounding the first region, and a ratio of the area of the opening region to the area of the masking region in the first region is different from a ratio of the area of the opening region to the area of the masking region in the second region,wherein the defect blocking layer comprises at least one insulating layer.
