Abstract
A light-emitting device includes a substrate, multiple light-emitting units that are disposed on the substrate, that are spaced apart by an isolation trench and that are and electrically interconnected by an interconnecting structure, and an insulating layer with thickness of 200 nm to 450 nm. A potential difference between adjacent two light-emitting units not in direct electrical connection is at least two times forward voltage of each of the light-emitting units. Each light-emitting unit includes a light-emitting stack and a light-transmissible current spreading layer. The insulating layer covers the light-transmissible current spreading layers and at least a part of the light-emitting stacks.
