Abstract

The invention provides a light-emitting device and a light-emitting device package. The light-emitting device includes: a light-emitting structure including a first conductive type semiconductor layer, an active layer and a second conductive type semiconductor layer sequentially stacked in that order; a first electrode disposed on a surface of the first semiconductor layer away from the active layer and electrically connected with the first semiconductor layer; a first electrode layer disposed on a surface of the second semiconductor layer away from the active layer and electrically connected with the second semiconductor layer; a second electrode penetrating through the light-emitting structure and being electrically connected with the first electrode layer; an insulating layer disposed between the light-emitting structure and the second electrode. The invention draws electrodes from the bottom of the light-emitting device, and therefore can avoid the leads to absorb and block light and thereby improve light extraction efficiency.
