A micro-light-emitting diode (micro-LED) includes a first type semiconductor layer, a second type semiconductor, a first current controlling layer, a first electrode, and a second electrode. The second type semiconductor layer and the first current controlling layer are joined with the first type semiconductor layer. The first current controlling layer has at least one opening therein. The first electrode is electrically coupled with the first type semiconductor layer through the opening. The second electrode is electrically coupled with the second type semiconductor layer. At least one of the first electrode and the second electrode has a light-permeable part. A vertical projection of the first current controlling layer on said one of the first electrode and the second electrode overlaps with the light-permeable part. The light-permeable part is transparent or semi-transparent.
