    摘要: Disclosed are a light emitting device and a light emitting device package. The light emitting device includes a first conductive semiconductor layer, an active layer on the first conductive semiconductor layer, and a second conductive semiconductor layer on the active layer. The active layer includes (T+1) barrier layers, T well layers between the (T+1) barrier layers, and a first dummy layer between N well layers adjacent to the second conductive semiconductor layer and N barrier layers adjacent to the N well layers, in which T>N≧1.
