Abstract
A light emitting element includes an emission stacked pattern and an insulating film. The emission stack pattern includes a first conductive semiconductor layer, an active layer disposed on the first conductive semiconductor layer, and a second conductive semiconductor layer disposed on the active layer. The insulating film surrounds an outer surface of the emission stacked pattern and has a non-uniform thickness.
