Abstract
A light-emitting device includes a number (N) (not smaller than two) of light-emitting units, a interconnect structure connecting the light-emitting units in series, first and second electrodes, and an auxiliary electrode structure. The light-emitting units each having an light-emitting stack having first and second semiconductor layers of opposite doping types and an active layer. The first and second electrodes are respectively connected to the first semiconductor layer of a first light-emitting unit and the second semiconductor layer of an Nlight-emitting unit. The auxiliary electrode structure is connected to the light-emitting stack of at least one of the light-emitting units.
