| 摘要 |
The invention discloses a light-emitting diode having an optical film structure thereon. The light-emitting diode includes a substrate, a light-emitting laminated structure, and an optical film structure. The light-emitting laminated structure is formed on the substrate, and the optical film structure is formed on the light-emitting laminated structure. The optical film structure is made of a dielectric material and has a light output plane, wherein the light output plane has plural roughened structures thereon.
