A light-emitting device includes a light-emitting structure, a lens, and a reflective layer. The light-emitting structure includes a light-emitting stack structure including a first-conductivity-type semiconductor layer, an active layer, and a second-conductivity-type semiconductor layer, which are stacked, a first electrode layer electrically connected to the first-conductivity-type semiconductor layer, and a second electrode layer electrically connected to the second-conductivity-type semiconductor layer. The lens is located on the light-emitting structure. The reflective layer is located on the lens.

Light-emitting device including chip-scale lens

A light-emitting device package includes a plurality of luminescent structures arranged spaced apart from each other in a horizontal direction, an intermediate layer on the plurality of luminescent structures, and wavelength conversion layers on the intermediate layer, the wavelength conversion layers vertically overlapping separate, respective luminescent structures of the plurality of luminescent structures. The intermediate layer may include a plurality of layers, the plurality of layers associated with different refractive indexes, respectively. The intermediate layer may include a plurality of sets of holes, each set of holes may include a separate plurality of holes, and each wavelength conversion layer may vertically overlap a separate set of holes on the intermediate layer.
