Abstract: A light emitting element includes: a light emitting element core including a first semiconductor layer, a light emitting layer on the first semiconductor layer, and a second semiconductor layer on the light emitting layer; and a first element insulating layer surrounding a side surface of the light emitting element core. An outer surface of the first element insulating layer has a first outer surface adjacent to one surface of the first semiconductor layer, the one surface of the first semiconductor layer being opposite to another surface of the first semiconductor layer facing the second semiconductor layer, and a second outer surface farther away from a side surface of the first semiconductor layer than the first outer surface is.
