Abstract:
A light emitting element includes a first light emitting portion and a second light emitting portion. The first light emitting portion includes a first stacked body having a first n-type layer, a first active layer, a first p-type layer, a first tunnel junction layer, and a second n-type layer. The second light emitting portion includes a second stacked body having a third n-type layer, a second p-type layer, a second tunnel junction layer, a fourth n-type layer, a second active layer, a third p-type layer, and a transmissive conductive film. A resistivity of the second n-type layer is higher than a resistivity of the transmissive conductive film. A thickness of the second n-type layer is larger than a thickness of the transmissive conductive film.
