1. A light emitting element comprising:
an emission stacked pattern having a predetermined shape in a view comprising a cross-sectional direction, the emission stacked pattern including a first end, a second end, a side portion completely surrounding the emission stacked pattern, the side portion being between the first end and the second end and extending from the first end to the second end in a vertical planar direction different from the cross-sectional direction, a first semiconductor layer adjacent to the first end, a second semiconductor layer adjacent to the second end, and an active layer between the first semiconductor layer and the second semiconductor layer; and
an insulating layer, at least a portion of the insulating layer covering the side portion of the emission stacked pattern, including an inner surface adjacent to the emission stacked pattern in the cross-sectional direction and an outer surface spaced apart from the inner surface; wherein
the outer surface includes a first outer surface position and a second outer surface position different from the first outer surface position,
the emission stacked pattern and the first outer surface position are spaced apart by a first distance,
the emission stacked pattern and the second outer surface position are spaced apart by a second distance, and
the first distance and the second distance are different each other.
