Abstract:
A light-emitting element includes a semiconductor light-emitting stack including a first semiconductor layer, a second semiconductor layer formed on the first semiconductor layer, and an active layer formed therebetween; a first conductive layer disposed on the second semiconductor layer and electrically connecting the second semiconductor layer; a second conductive layer disposed on the second semiconductor layer and electrically connecting the first semiconductor layer; and a cushion part disposed on and directly contacts the first conductive layer, wherein in a top view, the cushion part is surrounded by and electrically isolated from the second conductive layer.
