The present invention relates to a light-emitting element having increased light-emission efficiency by inducing an enhancement in light-emission intensity of various light-emitting materials introducible to the light-emitting element by using an anisotropic nanoparticle having a metal-dielectric core-shell structure. When an anisotropic metal nanoparticle-dielectric core-shell nanoparticle having an aspect ratio is used for an emission layer of the light-emitting element as in the present invention, two or more types of surface plasmon resonance bands of the anisotropic metal nanoparticle simultaneously induce excitation enhancement and emission enhancement of a light-emitting material, and a metal-dielectric core-shell nanostructure always separates the light-emitting material at a certain thickness of a dielectric shell, and thus an enhancement effect of a local electric field to be locally formed on the surface of the metal nanoparticle can be expected, thereby enabling a maximal increase in the light-emission intensity of the light-emitting material. In addition, a dielectric shell of an anisotropic metal nanoparticle-dielectric core-shell nanostructure maintains the shape and aspect ratio of the anisotropic metal nanoparticle inside the light-emitting element, in which a high heat is locally generated, and prevents the light-emitting material from being quenched by restricting the energy transition from an excited light-emitting material to the surface of the metal nanoparticle, thereby enabling the implementation of a light-emitting element having both improved light-emission efficiency and improved durability.
