Abstract
A light-emitting device is disclosed, comprising a substrate; a light-emitting structure on the substrate comprising a first region and a second region; a barrier layer on the first region having a bottom surface and a sidewall, wherein an angle between the sidewall and the bottom surface is between 10°70°; and a transparent conductive layer formed on the light-emitting structure and the barrier layer; wherein a difference between a thickness of the transparent conductive layer at the sidewall on the barrier layer and a thickness of the transparent conductive layer on the second region of the light-emitting structure forms a ratio not larger than 10 %.
