Abstract:
1. A light emitting diode, comprising: a compound semiconductor layer including an active layer; a conductive substrate bonded to the compound semiconductor layer; a first current blocking layer comprising a transparent insulating film provided on the compound semiconductor layer; a first electrode provided on the first current blocking layer, the first electrode comprising a pad electrode and a current spreading electrode extending from the pad electrode; a second current blocking layer comprising a transparent insulating film provided between the active layer and the conductive substrate; a light reflection mirror layer provided between the active layer and the conductive substrate; a second electrode passing through the second current blocking layer, the second electrode being provided only in a region overlapping the pad electrode in a top view; and a third electrode passing through the first current blocking layer, the third electrode electrically connecting the current spreading electrode to the compound semiconductor layer.
