Abstract
An ultraviolet light-emitting diode is disclosed. The ultraviolet light-emitting diode includes a transparent substrate, an ultraviolet illuminant epitaxial structure, and a transparent structure. The transparent substrate includes a first surface and a second surface which are opposite to each other, and a plurality of side surfaces surrounding and disposed between the first surface and the second surface. The ultraviolet illuminant epitaxial structure is disposed on the first surface of the transparent substrate. The transparent structure has a light-entering surface and a light-exiting surface which are opposite to each other. The light-entering surface of the transparent structure is adjacent to the second surface of the transparent substrate, and a refractive index of the transparent structure is between a refractive index of the transparent substrate and a refractive index of air.
