Abstract

A micro-light emitting diode (micro-LED) device includes a receiving substrate and a micro-LED. The micro-LED includes a first type semiconductor layer, a second type semiconductor layer, a current controlling layer, at least one reflective layer, and at least one first electrode. The second type semiconductor layer is joined with the first type semiconductor layer. The current controlling layer is joined with one of the first type semiconductor layer and the second type semiconductor layer, the current controlling layer having at least one opening therein. The reflective layer electrically is coupled with the first type semiconductor layer. The first electrode is disposed on a surface of the reflective layer facing the receiving substrate. The first electrode forms an adhesive bonding system with the receiving substrate.
