Abstract
According to an aspect of the present invention, a nitride semiconductor light emitting device includes a light emitting layer () having a quantum well structure with quantum well layers and barrier layers laminated alternately. The well layer is formed of a nitride semiconductor containing In, and the barrier layer is formed of a nitride semiconductor layer containing As, P or Sb. According to another aspect of the present invention, a nitride semiconductor light emitting device includes a light emitting layer having a quantum well structure with quantum well layers and barrier layers laminated alternately. The well layer is formed of GaNAsPSb(0<x+y+z≦0.3), and the barrier layer is formed of a nitride semiconductor containing In.
