A light emitting element includes: a substrate including a first surface including a first region and a second region; a first semiconductor layered body on the first region, the first semiconductor layered body comprising a first light emitting layer and including: a first lateral surface, and a second lateral surface opposite to the first lateral surface; and a second semiconductor layered body on the second region, the second semiconductor layered body comprising a second light emitting layer and including: a first lateral surface facing the second lateral surface and located on a first semiconductor layered body side of the second semiconductor layered body, and a second lateral surface opposite to the first lateral surface and located on a side opposite the first semiconductor layered body side of the second semiconductor layered body.

Light emitting element including first and second semiconductor layered bodies having defined relative lateral surface angles

A light emitting element includes: a substrate including a first surface including a first region and a second region; a first semiconductor layered body on the first region of the first surface of the substrate; and a second semiconductor layered body on the second region of the first surface of the substrate. A first angle defined by a first lateral surface of the first semiconductor layered body and the first region is smaller than a second angle defined by a second lateral surface of the first semiconductor layered body and the first region. A fourth angle defined by a second lateral surface of the second semiconductor layered body and the second region is smaller than a third angle defined by a first lateral surface of the second semiconductor layered body and the second region.
