Abstract
A light-emitting element includes a first semiconductor layer doped to have a first polarity, a second semiconductor layer doped to have a second polarity different from the first polarity, a light-emitting layer disposed between the first and second semiconductor layers, a shell layer formed on side surfaces of the first semiconductor layer, the light-emitting layer, and the second semiconductor layer, the shell layer including a divalent metal element, and an insulating film covering an outer surface of the shell layer and surrounding the side surface of the light-emitting layer.
