Abstract:
A light-emitting diode (LED) element is provided. The LED element includes a substrate, a diode structure layer and several light-guide structures. The light-guide structures are formed on at least one of the substrate and the diode structure layer. Each light-guide structure has an inner sidewall, and several spiral slits formed on the inner side wall.
