A light-emitting device includes a semiconductor epitaxial structure that has a first surface and a second surface, and that includes a first semiconductor layer, an active layer, and a second semiconductor layer. The active layer includes a quantum well structure having multiple periodic units, each including a well layer and a barrier layer greater in bandgap than the well layer. The bandgap of the barrier layer of at least one of the periodic units proximate to the first surface is smaller than that proximate to the second surface, and a thickness of the well layer of at least one of the periodic units proximate to the first surface is greater than that proximate to the second surface. In some embodiments, a bandgap of a second spacing layer disposed between the active and second semiconductor layers increases in a direction from the first surface to the second surface.

Light-emitting device

A micro light-emitting device includes an epitaxial structure and a bridge connection structure. The epitaxial structure includes a first mesa surface and a second mesa surface which are located on the same side of the epitaxial structure with a height difference therebetween, which have the same widths in a first direction, and which respectively have center points in the first direction that are aligned in a second direction perpendicular to the first direction. The bridge connection structure includes a first bridge connection layer that is formed on the first and second mesa surfaces so as to be symmetrically disposed on at least one of the first and second mesa surfaces with a line of symmetry thereof being in the second direction and passing through the center points of the first and second mesa surfaces. A method for making the same, and a light-emitting apparatus including the same are also disclosed.
