Abstract
A semiconductor light emitting device includes: a multilayer semiconductor body having a first conductivity-type semiconductor layer, a second conductivity-type semiconductor layer, an active layer between the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer, and at least one recess exposing the first conductivity-type semiconductor layer, and an insulating part on an internal sidewall of the at least one recess and an upper surface of the second conductivity-type semiconductor layer. The insulating part has an insulating spacer on the internal sidewall of the recess, and a lateral surface of the insulating spacer has a surface without an angular point from an upper end to a lower end thereof.
