Light-emitting device

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 plurality of light-emitting elements arranged on a first column, a second plurality of light-emitting elements arranged on a second column, and the first column and the second column are separated by a trench, wherein each of the plurality of light-emitting elements comprises a first semiconductor layer, a second semiconductor layer, and an active layer formed between the first semiconductor layer and the second semiconductor layer, and wherein the first plurality of light-emitting elements comprises a first light-emitting element, and the second plurality of light-emitting elements comprises a second light-emitting element;
• a first lower electrode formed on the first semiconductor layer of the first light-emitting element;
• a first upper electrode formed on the second semiconductor layer of the first light-emitting element;
• a first bottom electrode portion contacting the first lower electrode;
• a first top electrode portion contacting the first upper electrode, wherein the first bottom electrode portion covers the first light-emitting element and the second light-emitting element or the first top electrode portion covers the first light-emitting element and the second light-emitting element;
• a second lower electrode formed on the first semiconductor layer of the second light-emitting element;
• a second upper electrode formed on the second semiconductor layer of the second light-emitting element;
• a second bottom electrode portion contacting the second lower electrode;
• and
• a second top electrode portion contacting the second upper electrode.
