摘要:
A light-emitting device includes a first edge to a fourth edge; a semiconductor stack formed on a substrate, including a first semiconductor layer, a second semiconductor layer and an active layer; a first electrode formed on the first semiconductor layer, including a first pad electrode and a first finger electrode; and a second electrode formed on the second semiconductor layer, including a second pad electrode and a second finger electrode; wherein the first finger electrode is disposed at and along the first edge; and the first finger electrode includes a first overlapping portion overlapping the second finger electrode; the second finger electrode includes a second overlapping portion overlapping the first finger electrode and a non-overlapping portion that does not overlap the first finger electrode; and the second overlapping portion is not parallel with the first overlapping portion and the non-overlapping portion is not parallel with the first edge.
