Abstract
A stacked light emitting device includes a first LED stack, a second LED stack disposed under the first LED stack, a third LED stack disposed under the second LED stack, and a plurality of pads disposed over the first LED stack. Each of the first, second, and third LED stacks has a light generation region and a peripheral region disposed around the light generation region. The plurality of pads is disposed on the peripheral region of the first LED stack.
