Light emitting device, light emitting device package and method for fabricating light emitting device

摘要

PURPOSE: A light emitting device, a light emitting device package, and a method for manufacturing a light emitting device are provided to improve the light efficiency of a light emitting device by increasing the number of electronics and holes which are recombined in an active layer. CONSTITUTION: An n-type semiconductor layer is formed on a substrate. An active layer is formed on the n-type semiconductor layer. The active layer includes one or more well layers and barrier layers. An electron blocking layer consisting of InAlN(Indium Aluminium Nitride) is formed on the active layer. A p-type semiconductor layer is formed on the electron blocking layer.
