Abstract
There is provided a semiconductor light emitting device including a conductive substrate, a first electrode layer, an insulating layer, a second electrode layer, a second semiconductor layer, an active layer, and a first semiconductor layer that are sequentially stacked. The contact area between the first electrode layer and the first semiconductor layer is 3% to 13% of the total area of the semiconductor light emitting device, and thus high luminous efficiency is achieved.
