Semiconductor light emitting device and semiconductor light emitting apparatus having the same

In example embodiments, a semiconductor light emitting device includes a light emitting structure, first and second insulating layers, a barrier metal layer, and an electrode. The light emitting structure includes an active layer between a first and second conductivity-type semiconductor layer. The first insulating layer is on the light emitting structure and defines a first one and a second one of first openings that respectively expose the first and second conductivity-type semiconductor layers. The barrier metal layer is on the first insulating layer and electrically connected to the first and second conductivity-type semiconductor layers through the first and second one of the first openings. The second insulating layer is on the barrier metal layer and defines a second opening that partially exposes the barrier metal layer. The electrode is on the barrier metal layer and electrically connected to the first and second conductivity-type semiconductor layers through the barrier metal layer.
