Abstract
This disclosure discloses a light-emitting device. The light-emitting device comprises: a substrate; and a first light-emitting unit comprising a plurality of light-emitting diodes electrically connected to each other on the substrate. A first light-emitting diode in the first light-emitting unit comprises a first semiconductor layer with a first conductivity-type, a second semiconductor layer with a second conductivity-type, and a light-emitting stack formed between the first and second semiconductor layers. The first light-emitting diode in the first light-emitting unit further comprises a first connecting layer on the first semiconductor layer for electrically connecting to a second light-emitting diode in the first light-emitting unit; a second connecting layer, separated from the first connecting layer, formed on the first semiconductor layer; and a third connecting layer on the second semiconductor layer for electrically connecting to a third light-emitting diode in the first light-emitting unit.
