Classification: CPC H | IPC H

Claim 0:
1. A light-emitting device, comprising:
a substrate comprising a top surface;
a plurality of light-emitting elements formed on the substrate, wherein the plurality of light-emitting elements comprises a first light-emitting element and a second light-emitting element, wherein each of the plurality of light-emitting elements comprises a first semiconductor layer, and a mesa comprising a second semiconductor layer and an active layer formed on the first semiconductor layer;
a first bottom electrode portion formed on the first light-emitting element and electrically connecting the first semiconductor layer of the first light-emitting element;
a first top electrode portion formed on the first light-emitting element and electrically connecting the second semiconductor layer of the first light-emitting element, wherein a first ratio of a first surface area of the first top electrode portion to that of the first bottom electrode portion on the first light-emitting element is between 1.1 and 1.6;
a second bottom electrode portion formed on the second light-emitting element and electrically connecting the first semiconductor layer of the second light-emitting element; and
a second top electrode portion formed on the second light-emitting element and electrically connecting the second semiconductor layer of the second light-emitting element.
