PURPOSE: A light emitting device is provided to improve light emitting efficiency by maximizing the reflection efficiency of light. CONSTITUTION: A light emitting structure includes a first conductivity type semiconductor layer(222), an active layer(224), and a second conductivity type semiconductor layer(226). A first electrode layer is in contact with the second conductivity type semiconductor layer. A second electrode layer is in contact with the first conductivity type semiconductor layer. An insulation layer(240) is interposed between the first electrode layer and the second electrode layer. A reflection layer(250) faces the light emitting structure and places the first electrode layer between the reflection layer and the light emitting structure.
