A semiconductor light emitting device includes a light emitting structure including a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer; and an insulating layer on the light emitting structure and including first and second through-holes. The insulating layer includes a first lower insulating layer and a second lower insulating layer. The first insulating layer is disposed on the first conductivity-type semiconductor layer and is surrounded by the second lower insulating layer with the first through-hole interposed therebetween.

Semiconductor light emitting device

A semiconductor light emitting device includes a stacked semiconductor structure including a first conductivity-type semiconductor layer having a top surface divided into a first region and a second region, and an active layer and a second conductivity-type semiconductor layer disposed sequentially on the second region of the first conductivity-type semiconductor layer. First and second contact electrodes are disposed in the first region of the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer, respectively. A current spreading layer is disposed on the second contact electrode and comprises a first conductive layer having a first resistivity and a second conductive layer having a second resistivity smaller than the first resistivity alternately stacked.
