Abstract
A LED structure includes a substrate, a plurality of LED units, a bonding layer and a metal contact. The substrate includes a driving circuit, and a plurality of LED units is formed on the substrate. The bonding layer is formed between the substrate and the plurality of LED units, and the metal contact is formed in the bonding layer beneath each LED unit to electrically connect each LED unit with a contact pad of the driving circuit. A first sectional area of the metal contact is smaller than a second sectional area of each LED unit.
