Claim 0:
1. A light-emitting device, comprising:
a substrate comprising a top surface;
a plurality of light-emitting units formed on the substrate and comprising a first light-emitting unit and a second light-emitting unit, wherein the plurality of light-emitting units each comprises a first semiconductor layer, an active layer, and a second semiconductor layer;
an insulating layer comprising a plurality of opening structure respectively formed on the plurality of light-emitting units, wherein each of the plurality of opening structures comprises a first insulating layer opening and a second insulating layer opening;
a first extension electrode covering the first light-emitting unit, wherein the first extension electrode covers the first insulating layer opening on the first light-emitting unit without covering the second insulating layer opening on the first light-emitting unit;
a second extension electrode covering the second light-emitting unit, wherein the second extension electrode covers the second insulating layer opening on the second light-emitting unit without covering the first insulating layer opening on the second light-emitting unit; and
a plurality of connecting electrodes formed between two adjacent of the plurality of light-emitting units, wherein the plurality of connecting electrodes is formed on two sides of the first extension electrode without overlapping the first extension electrode or two sides of the second extension electrode without overlapping the second extension electrode.
