A nitride-based semiconductor light emitting device having a structure capable of improving optical output performance, and methods of manufacturing the same are provided. The active layer may include a first barrier layer formed of InxGa(1-x)N (0.01≰x≰0.05) on a n-type semiconductor layer, a first diffusion barrier layer formed of InyGa(1-y)N (0≰y<0.01) on the first barrier layer, and doped with an anti-defect agent including at least one of an N (nitrogen) element and a Si (silicon) element, a quantum well layer formed of InzGa(1-z)N (0.25≰z≰0.35) on the first diffusion barrier layer, a second diffusion barrier layer formed of InyGa(1-y)N (0≰y<0.01) on the quantum well layer, and doped with an anti-defect agent including at least one of an N element and a Si element, and a second barrier layer formed of InxGa(1-x)N (0.01≰x≰0.05) on the second diffusion barrier layer. The nitride-based semiconductor light emitting device may include an n-type semiconductor layer, the active layer, and a p-type semiconductor layer that are sequentially stacked on a substrate. |
