The present disclosure provides a semiconductor light-emitting device and a semiconductor light-emitting component. The semiconductor light-emitting device includes a substrate, a first semiconductor contact layer, a semiconductor light-emitting stack including an active layer, a first-conductivity-type contact structure, a second semiconductor contact layer, a second-conductivity-type contact structure and a first electrode pad. The first-conductivity-type contact structure is electrically connected to the first semiconductor contact layer. The second-conductivity-type contact structure is electrically connected to the second semiconductor contact layer. The first-conductivity-type contact structure has a first bottom surface and a first top surface, and the active layer has a second bottom surface and a second top surface. The first bottom surface is lower than the second bottom surface, and the first top surface is higher than the second top surface in a cross-sectional view of the semiconductor light-emitting device.
