Claim Text:
1. A light emitting device comprising: a first-conduction-type semiconductor layer; a second-conduction-type semiconductor layer; an active layer disposed between the first-conduction-type semiconductor layer and the second-conduction-type semiconductor layer, the active layer comprising barrier layers and well layers alternately laminated at least one time; a first region disposed between a first well layer and a first barrier layer adjacent to one side of the first well layer; and a second region disposed between the first well layer and a second barrier layer adjacent to another side of the first well layer, wherein the first region has a linearly decreasing energy band gap, wherein the second region has a linearly decreasing energy band gap, and wherein a slope of a gradient of energy band gap from the first well layer to the first barrier layer is different from a slope of a gradient of energy band gap from the first well layer to the second barrier layer.
