Abstract
A nanorod type micro-light emitting diode (LED) includes a nanorod stack structure including a multi-quantum well layer and emitting light from a side surface, and a functional material layer covering the side surface of the nanorod stack structure and increasing a total internal reflection angle of the nanorod stack structure. The functional material layer has a refractive index between a refractive index of the nanorod stack structure and a refractive index of air, and includes a plurality of material layers having a refractive index distribution in which a refractive index decreases as a distance from the side surface increases.
