Abstract
A light-emitting device comprising: a light-emitting stacked layer having a 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; a transparent conductive oxide layer formed on the second conductivity type semiconductor layer wherein the transparent conductive oxide layer having a first portion and a second portion and the upper surface of the transparent conductive oxide layer is a textured surface; a first electrode formed on the second portion of the transparent conductive oxide layer, and a second electrode formed on the first conductivity type semiconductor layer; a planarization layer formed on the first portion of the transparent conductive oxide layer, and the second electrode; and a reflective layer formed on the planarization layer that is devoid of the first electrode and the second electrode.
