1. A light-emitting element comprising:
a core comprising:
a first semiconductor layer;
a second semiconductor layer disposed on the first semiconductor layer; and
an emissive layer disposed between the first semiconductor layer and the second semiconductor layer;
an interlayer dielectric film surrounding a side surface of the core;
a first element insulating film surrounding an outer surface of the interlayer dielectric film; and
a second element insulating film surrounding an outer surface of the first element insulating film, wherein
the interlayer dielectric film comprises an oxide insulating material having a dielectric constant of about 10 or more, and
the interlayer dielectric film has a thickness of less than 5 nm.
