SEMICONDUCTOR LIGHT EMITTING DEVICE

摘要

A semiconductor light emitting device for improving luminance according to the embodiment of the present invention includes a light emitting structure which has a first conductivity type semiconductor layer and a second conductivity type semiconductor layer, and an active layer arranged between the first and second conductive type semiconductor layers, a first electrode which is arranged on the light emitting structure and is electrically connected to the first conductivity type semiconductor layer, and a second electrode which is arranged on the light emitting structure and is electrically connected to the second conductivity type semiconductor layer. The second electrode includes a first layer arranged on the second conductivity type semiconductor layer, and a second layer which is arranged on the first layer and has a surface resistance which is higher than that of the first layer and a thickness which is thinner than that of the first layer.
