Abstract
A light-emitting device is provided. The light-emitting device comprises: a light-emitting stack having an active layer; an electrode structure on the light-emitting stack and comprising a first electrode and an extension electrode protruding from the first electrode toward an edge of the light-emitting device in a first extending direction; a transparent insulating layer between the light-emitting stack and the electrode structure, wherein the transparent insulating layer comprises a first part and an extension part protruding from the first part toward the edge of the light-emitting device in a second extending direction; wherein a surface area of a surface of the first electrode distal from the transparent insulating layer is smaller than a surface area of a surface of the transparent insulating layer distal from the light-emitting stack, the first electrode is right above the first part, and a part of the extension electrode is right above the extension part.
