Abstract
A LED device is provided. The LED device has a conductive carrier substrate, a light-emitting structure, a plurality of pillar structures, a dielectric layer, a first electrode and a second electrode. The light-emitting structure is located on the conductive carrier substrate. The pillar structures are located on the light-emitting structure. The dielectric layer is to cover a sidewall of the pillar structure. The first electrode is located over the pillar structure, and the second electrode is located on the conductive carrier substrate.
