Various embodiments may provide a highly efficient micro light-emitting diode (LED) in a low current range, a method of fabricating the same, and a display including the same. The micro LED includes a first conductive type semiconductor layer and a second conductive type semiconductor layer and an active layer disposed between the first conductive type semiconductor layer and the second conductive type semiconductor layer and having a single quantum well structure. The single quantum well structure may be formed so that a ratio of a conduction band offset of any one of the first conductive type semiconductor layer or the second conductive type semiconductor layer and a valence band offset of the other of the first conductive type semiconductor layer or the second conductive type semiconductor layer becomes greater than 0 and less than 1.
