Abstract
There is provided a light emitting device that can minimize reflection or absorption of emitted light, maximize luminous efficiency with the maximum light emitting area, enable uniform current spreading with a small area electrode, and enable mass production at low cost with high reliability and high quality. A light emitting device according to an aspect of the invention includes a light emitting lamination including a first conductivity type semiconductor layer, a second conductivity type semiconductor layer, and an active layer, and a conductive substrate at one surface thereof. Here, the light emitting device includes a barrier unit separating the light emitting lamination into a plurality of light emitting regions, a first electrode structure, and a second electrode structure. The first electrode structure includes a bonding unit, contact holes, and a wiring unit connecting the bonding unit to the contact holes.
