Abstract
A flip-chip light-emitting device includes a light-emitting unit, a first electrode, and a second electrode. The light-emitting unit includes a first type semiconductor layer, an active layer, and a second type semiconductor layer. The first electrode is disposed on the light-emitting unit and electrically connected to the first type semiconductor layer. The second electrode is disposed on the light-emitting unit and electrically connected to the second type semiconductor layer. The first electrode or the second electrode is free of gold, and includes an aluminum layer and at least one platinum layer disposed on the aluminum layer opposite to the light-emitting unit.
