Semiconductor light emitting device having reflective electrode on multilayer insulating structure

Abstract

A semiconductor light emitting device including a substrate; a light emitting structure including a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer sequentially stacked on the substrate; a transparent electrode layer on the second conductivity-type semiconductor layer; a first insulating layer on the transparent electrode layer and having a plurality of first through-holes; a multilayer insulating structure on the first insulating layer and having a plurality of second through-holes overlapping the plurality of first through-holes, respectively, the multilayer insulating structure being spaced apart from an edge of the light emitting structure; a reflective electrode layer on the multilayer insulating structure and connected to the transparent electrode layer through the plurality of first through-holes and the plurality of second through-holes; and a second insulating layer between the multilayer insulating structure and the reflective electrode layer.
