Claim Text:
1. A light emitting device comprising: a light emitting structure layer that includes a first conductive type semiconductor layer, an active layer on a top surface of the first conductive type semiconductor layer, and a second conductive type semiconductor layer on a top surface of the active layer; a first electrode connected to the first conductive type semiconductor layer; a current spreading layer on a top surface of the second conductive type semiconductor layer; an insulating layer on an upper surface of the first conductive type semiconductor layer and a top surface of the current spreading layer; and a second electrode on a top surface of the current spreading layer and the insulating layer, wherein the light emitting structure layer includes a plurality of groove parts in which the upper surface of the first conductive type semiconductor layer is exposed, wherein the first electrode includes a first pad disposed on the upper surface of the first conductive type semiconductor layer, a plurality of first contact portions disposed on the upper surface of the first conductive type semiconductor layer and a plurality of first bridge portions on a top surface of the insulating layer, wherein the second electrode includes a second pad disposed on the top surface of the current spreading layer, a plurality of second contact portions contacting the top surface of the current spreading layer and a plurality of second bridge portions on the top surface of the insulating layer, and wherein the plurality of first bridge portions are extended from the first pad at an acute angle to each other, wherein each of the plurality of first bridge portions is connected to the first pad and a corresponding separate one of the plurality of first contact portions, wherein each of the plurality of second bridge portions is connected to the second pad and a corresponding separate one of the plurality of second contact portions, wherein one of the plurality of second bridge portions is disposed between the plurality of first bridge portions on the insulating layer, and wherein the plurality of second bridge portions is not overlapped with the plurality of first contact portions in a vertical direction.
