Abstract
A micro light-emitting device includes a micro light-emitting diode and a light-emitting structure. The micro light-emitting diode includes a semiconductor light-emitting unit that emits an excitation light having a first wavelength. The light-emitting structure is disposed on the micro light-emitting diode, and is configured to be excited by the excitation light to emit an excited light having a second wavelength. The light-emitting structure is a multiple quantum well structure. A display including the micro light-emitting device is also disclosed.
