Micro light-emitting diode and manufacturing method of micro light-emitting diode

A micro light-emitting diode includes a first micro light-emitting diode including a first light-emitting layer and emitting light at a first wavelength, and a second micro light-emitting diode including the first light-emitting layer and a second light-emitting layer emitting light at a second wavelength longer than the first wavelength, in which the second light-emitting layer is a nitride semiconductor layer doped with a second rare earth element, and a nitride semiconductor of the first micro light-emitting diode and the nitride semiconductor of the second micro light-emitting diode are separated from each other.
