Abstract
A semiconductor light-emitting component includes a semiconductor epitaxial structure that includes a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer. The first conductivity type semiconductor layer includes a first current spread layer having a first and second parts which are stacked on one another. The first part has an average band gap greater than that of the second part. The second part is formed by alternately stacking first sub layers and second sub layers one on another. Each of the first sub layers has a band gap different from that of each of the second sub layers. A light-emitting device including the semiconductor light-emitting component is also disclosed.
