1. A stacked light emitting device, comprising:
a first LED stack;
a second LED stack disposed under the first LED stack;
a third LED stack disposed under the second LED stack;
each of the first LED stack, the second LED stack, and the third LED stack has a light generation region and a peripheral region disposed around the light generation region;
a plurality of pads disposed over the first LED stack; and
a third-1 connector and a third-2 connector disposed on the third LED stack, wherein:
the third-1 connector and the third-2 connector are electrically connected to a first conductivity type semiconductor layer and a second conductivity type semiconductor layer of the light generation region of the third LED stack, respectively, and
the third-1 connector, the third-2 connector, or both cover a side surface of the peripheral region of the third LED stack,
wherein, in each of the first LED stack, the second LED stack and the third LED stack, the peripheral region is arranged to surround the light generation region on a horizontal plane.
