Abstract: A light-emitting device of an embodiment of the present application comprises a semiconductor layer sequence provided with a first main side, a second main side, and an active layer; a beveled trench formed in the semiconductor layer sequence, having a top end close to the second main side, a bottom end, and an inner sidewall connecting the top end and the bottom end. In the embodiment, the inner sidewall is an inclined surface. The light-emitting device further comprises a dielectric layer disposed on the inner sidewall of the beveled trench and the second main side; a first metal layer formed on the dielectric layer; a carrier substrate; and a first connection layer connecting the carrier substrate and the semiconductor layer sequence.
