Abstract
In an embodiment, a light emitting device comprises a light emitting diode chip and a spherical extending electrode. The light emitting diode chip includes a semiconductor epitaxial structure, a first electrode and a second electrode. The first electrode and the second electrode are disposed on two opposite sides of the semiconductor epitaxial structure, respectively. The first electrode is disposed between the semiconductor epitaxial structure and the spherical extending electrode, and the spherical extending electrode is electrically connected to the semiconductor epitaxial structure electrically through the first electrode. The volume of the spherical extending electrode is greater than that of the light emitting diode chip.
