Abstract
A micro light-emitting device includes an epitaxial structure, a first type pad, a second type pad, and a current commanding structure. The epitaxial structure includes a first type semiconductor layer, a light-emitting layer, and a second type semiconductor layer. The first type pad is electrically connected to the first type semiconductor layer. The second type pad is electrically connected to the second type semiconductor layer. The current commanding structure is disposed between the second type semiconductor layer and the second type pad. A contact resistance between the second type semiconductor layer and the current commanding structure is smaller than a contact resistance between the second type semiconductor layer and the second type pad. An orthogonal projection area of the current commanding structure on the second type semiconductor layer is smaller than an orthogonal projection area of the second type pad on the second type semiconductor layer.
