Abstract
A gallium nitride light emitting device having contact electrodes, which comprises: a substrate; a first type gallium nitride layer formed on the surface of the substrate; an active layer formed on the surface of the first type gallium nitride layer, and exposing a portion of the surface of the first type gallium nitride layer; a second type gallium nitride layer formed on the surface of the active layer; a first type contact electrode formed the exposed portion of the surface of the first type gallium nitride layer; and a second type contact electrode formed on a portion of the surface of the second type gallium nitride layer, which comprises: a second type contact pad, and at least a metallic line in contact with the second type contact pad.
