SEMICONDUCTOR LIGHT EMITTING DEVICE

摘要

An embodiment of the present invention provides a semiconductor light emitting device with improved light extraction efficiency. The semiconductor light emitting device includes a substrate, a first reflective layer which is arranged on the substrate and includes a first opening part; a first conductivity type semiconductor layer which is extended from the first opening part, is grown, and is connected to the first reflective layer; a second reflective layer which is arranged on the first conductivity type semiconductor layer and has a lower surface separated from the upper surface of the first opening part; and nanolight emitting structures which include a nanocore which is extended from the second opening part and is made of a first conductivity type semiconductor, an active layer and a second conductivity type semiconductor layer which are successively arranged on the nanocore.
