Abstract: A light-emitting element package is provided. The light-emitting element package includes light-emitting structures spaced from each other, the light-emitting structures including first, second and third light-emitting structures, each of the light-emitting structures being configured to emit light of a first color; a first wavelength conversion layer provided on the first light-emitting structure at a first position corresponding to the first light-emitting structure, the first wavelength conversion layer being configured to convert light of the first color into light of a second color; a first oxide film provided on the first wavelength conversion layer; and a second wavelength conversion layer disposed in the first oxide film at a second position corresponding to the second light-emitting structure, the second wavelength conversion layer being configured to convert light of the first color into light of a third color. The first wavelength conversion layer and the second wavelength conversion layer have different structures.
