Abstract
A micro light-emitting device includes an epitaxial structure, a first type pad, a current commanding structure and an insulating layer. The epitaxial structure includes a first type semiconductor layer, a light-emitting layer and a second type semiconductor layer. The first type pad is disposed on the epitaxial structure and electrically connected to the first type semiconductor layer. The current commanding structure is disposed on the epitaxial structure and electrically connected to the second type semiconductor layer. An orthogonal projection area of the current commanding structure on the second type semiconductor layer is smaller than a surface area of a surface of the second type semiconductor layer. The insulating layer contacts a portion of the current commanding structure and a portion of the surface of the second type semiconductor layer. The insulating layer has an opening exposing at least a portion of the portion of the current commanding structure.
