Light-emitting device

This disclosure discloses a light-emitting device includes a semiconductor stack, an electrode, an electrode post, a reflective insulating layer, an extending electrode, and a supporting structure. The electrode is disposed on a lower surface of the semiconductor stack, and electrically connected to the semiconductor stack. The electrode post is disposed on the electrode. The reflective insulating layer surrounds the electrode post, and has a bottom surface which is coplanar with the electrode post. The extending electrode is disposed on an upper surface of the semiconductor stack. The supporting structure is located on the extending electrode.
