Abstract

A light-emitting element, includes a substrate; a first light-emitting stack formed on the substrate, including a triangular upper surface parallel to the substrate, and wherein the triangular upper surface has three sides and three vertexes; a first electrode formed on the first light-emitting stack and located near a first side of the three sides of the triangular upper surface; and a second electrode formed on the first light-emitting stack; including a second electrode pad near a first vertex of the three vertexes; and a second electrode extending part extending from the second electrode pad in two directions, disposed along other two sides of the three sides to surround the first electrode and stopping at the first side to form an opening.
