Abstract:
1. A light emitting device, comprising: a plurality of light emitting cell each comprising an N-type semiconductor layer, a P-type semiconductor layer disposed on the N-type semiconductor layer and an active layer interposed between the N-type semiconductor layer and the P-type semiconductor layer, wherein the active layer and the P-type semiconductor layer cover a portion of a top surface of the N-type semiconductor layer, such that the top surface of the N-type semiconductor layer is partially exposed; a first insulation layer covering the plurality of light emitting cells, and comprising openings which expose at least partial top surfaces of the N-type semiconductor layer and the P-type semiconductor layer; an ohmic contact layer contacting the N-type semiconductor layer through the opening, and a second insulation layer covering the ohmic contact layer and the first insulation layer, wherein the ohmic contact layer at least partially covers the first insulation layer, wherein the second insulation layer has a substantially constant thickness with respect to surfaces of the plurality of light emitting cells, and wherein side surface of the P-type semiconductor layer and the active layer are inclined.
