1. A semiconductor light emitting device comprising:

  • a light emitting structure comprising a first conductive semiconductor layer, an active layer under the first conductive semiconductor layer, and a second conductive semiconductor layer under the active layer;

    a reflective layer under the light emitting structure;

    a first electrode layer connected to the first conductive semiconductor layer;

    a metal layer under the reflective layer; and

    a conductive support member under the metal layer,wherein the reflective layer has a thickness of 650 nm to 1550 nm,wherein a top surface of the first conductive semiconductor layer includes a first region adjacent to an edge and a second region adjacent to the first region,wherein the first region includes a flat surface and the second region includes a rough surface,wherein the second region is located at a lower position than the first region in the top surface of the first conductive semiconductor layer,wherein an edge region of a top portion of the conductive support member has a protrusion, andwherein the edge region of the top portion of the conductive support member is not overlapped with the second region of the top surface of the first conductive semiconductor layer in a vertical direction.
