Abstract: A light-emitting diode (LED) package includes a light-emitting structure, an optical wavelength conversion layer on the light-emitting structure, and an optical filter layer on the optical wavelength conversion layer. The light-emitting structure includes a first-conductivity-type semiconductor layer, an active layer on the first-conductivity-type semiconductor layer, and a second-conductivity-type semiconductor layer on the active layer, and emits first light having a first peak wavelength. The optical wavelength conversion layer absorbs the first light emitted from the light-emitting structure and emits second light having a second peak wavelength different from the first peak wavelength. The optical filter layer reflects the first light emitted from the light-emitting structure and transmits the second light emitted from the optical wavelength conversion layer.

Abstract: The present application relates to a light-emitting device and method of manufacturing the same. The device includes a lower portion, and vertical light-emitting structures disposed on the lower portion. A conductive member partially surrounds the vertical light-emitting structures, and reflective members are disposed between the vertical light-emitting structures. The reflective members reflect light that is emitted in a lateral direction from the vertical light-emitting structures to minimize the number of times that light emitted in a lateral direction from the vertical light-emitting structure is transmitted through the light-absorbing member, thereby increasing a luminous efficiency.
