PURPOSE: A light emitting device, a manufacturing method thereof, and a light emitting device package are provided to improve the light extraction efficiency of the light emitting device by forming a distance between an active layer and a reflection layer according to a constructive interference condition. CONSTITUTION: An ohmic layer(157) is formed on a reflection layer(158). A second conductive semiconductor layer(150) is formed on the ohmic layer. An active layer(140) is formed on the second conductive semiconductor layer to generate light. A first conductive semiconductor layer(130) is formed on the active layer. An electrode(170) is formed on the first conductive semiconductor layer. |
