1. A light emitting element, comprising:
a first semiconductor layer, a second semiconductor layer, and an active layer between the first semiconductor layer and the second semiconductor layer;
a passivation layer surrounding an outer surface of at least one selected from the first semiconductor layer, the second semiconductor layer, and the active layer; and
an insulation layer surrounding an outer surface of the passivation layer,
wherein the passivation layer comprises a two-dimensional (2D) material, and
wherein the 2D material comprises at least one selected from CaF2, Ti0.9O2, Mica, WS2, MoS2, Ni(OH)2, Cu(OH)2, Mg(OH)2, GaS, and Talc, and
wherein the passivation layer comprises a plurality of passivation layers spaced apart from each other in a length direction of the light emitting element on the outer surface of the at least one selected from the first semiconductor layer, the second semiconductor layer, and the active layer.
