Abstract
An LED device includes an epitaxial layered structure, a current spreading layer, a first insulating layer and a reflective structure. The current spreading layer is formed on a surface of the epitaxial layered structure. The first insulating layer is formed over the current spreading layer, and is formed with at least one first through hole to expose the current spreading layer. The reflective structure is formed on the first insulating layer, extends into the first through hole, and contacts the current spreading layer. The current spreading layer is formed with at least one opening structure to expose the surface of the epitaxial layered structure.
