Abstract
A light-emitting element comprises a first semiconductor layer, a first light-emitting structure and a second light-emitting structure on the first semiconductor layer, a first electrode on the first semiconductor layer, a second electrode on the first light-emitting structure, a first trench between the first light-emitting structure and the second light-emitting structure, exposing a first upper surface of the first semiconductor layer, and a second trench formed in the first light-emitting structure, exposing a second upper surface of the first semiconductor layer, wherein the first trench is devoid of the first electrode and the second electrode formed therein, wherein the first electrode is formed in the second trench.
