Abstract:
A light-emitting device including: a light-emitting stacked layer having first conductivity type semiconductor layer, a light-emitting layer formed on the first conductivity type semiconductor layer, and a second conductivity type semiconductor layer formed on the light-emitting layer, wherein the upper surface of the second conductivity type semiconductor layer is a textured surface; a first planarization layer formed on a first partial of the upper surface of the second conductivity type semiconductor layer; a first transparent conductive oxide layer formed on the first planarization layer and a second partial of the second conductivity type semiconductor layer, including a first portion in contact with the first planarization layer and a second portion having a first plurality of cavities in contact with the second conductivity type semiconductor layer; and a first electrode formed on the first portion of the first transparent conductive oxide layer.
