    摘要: A light emitting device includes a first semiconductor layer having a first conductive dopant, an active layer on the first semiconductor layer, an electron blocking layer on the active layer, a carrier injection layer between the active layer and the electron blocking layer, and a second semiconductor layer having a second conductive dopant on the electron blocking layer. The carrier injection layer includes the first conductive dopant and the second conductive dopant, and the first conductive dopant of the carrier injection layer has a concentration lower than a concentration of the second conductive dopant.
