1. A light emitting device array, comprising:

  • a substrate;

    a plurality of light emitting devices spaced from one another in a horizontal direction on the substrate;

    a conductive interconnection layer to connect the two light emitting devices among the plurality of light emitting devices; and

    a first insulating layer between the light emitting devices and the conductive interconnection layer,wherein respective light emitting devices comprise;

    a light emitting structure including lower and upper semiconductor layers having different conductive types, and an active layer provided between the lower and upper semiconductor layers;

    a first electrode layer provided on the upper semiconductor layer; and

    a second electrode layer provided on the lower semiconductor layer,wherein the conductive interconnection layer connects the first electrode layer of one of the two light emitting devices to the second electrode layer of the other of the two light emitting devices,wherein the first electrode layer includes a first adhesive layer and a first bonding layer overlapping each other,wherein a reflective layer is not provided between the first adhesive layer and the first bonding layer,wherein the conductive interconnection layer comprises a third adhesive layer and a third bonding layer overlapping each other, andwherein a reflective layer is not disposed between the third adhesive layer and the third bonding layer.
