Abstract:
A light emitting element includes a semiconductor layered body, an insulating film, first and second electrodes, and first and second external connection parts. The first semiconductor layer is exposed from the light emitting layer and the second semiconductor layer at exposed portions arranged in columns each extending in a first direction. The insulating film defines openings respectively located above the exposed portions.

The first external connection part is connected to the first electrode and spaced apart from the exposed portions in the plan view. The first external connection part has a shape elongated in the first direction between adjacent ones of the columns of the exposed portions. The second external connection part is connected to the second semiconductor layer via the second electrode.
