Abstract

Disclosed herein is a light-emitting device. The light-emitting device includes a substrate with a top surface; a first light-emitting structure unit and a second structure light-emitting unit disposed on the top surface, the first light-emitting structure unit and the second light-emitting structure unit being spaced apart from each other, wherein each of the first light-emitting structure unit and the second light-emitting structure unit includes a lower layer having a first conductivity and an upper layer having a second conductivity; a trench between the first light-emitting structure unit and the second light-emitting structure unit, including a bottom portion which is a part of the top surface; an isolation layer, disposed on the trench and covering the bottom portion; and an electrical connection, electrically connecting the first light-emitting structure unit and the second light-emitting structure unit; wherein the lower layer includes an inclined sidewall and the electrical connection contacts the inclined sidewall.
