Abstract:
A light-emitting diode device includes: a substrate; a light-emitting layered structure formed on the substrate; a multi-functional layer having a first main portion and formed on the light-emitting layered structure for spreading current laterally and for reflecting light emitted from the light-emitting layered structure; and first and second electrodes electrically coupled to the light-emitting layered structure. The first electrode is formed on the light-emitting layered structure and has a first electrode main part. The first main portion of the multi-functional layer is aligned below and is provided with a size larger than that of the first electrode main part.
