Abstract:
A nitride semiconductor light-emitting element comprising an n-type layer, a light-emitting layer on the n-type layer and a p-type layer on the light-emitting layer, the p-type layer comprising a first p-type sublayer on the light-emitting layer and a second p-type sublayer on the first p-type sublayer, the first p-type sublayer containing hydrogen element and a p-type impurity element, the second p-type sublayer containing hydrogen element and a p-type impurity element which is the same as or different from the p-type impurity element in the first p-type sublayer, and a molar ratio of hydrogen element to the p-type impurity element in the first p-type sublayer being lower than a molar ratio of hydrogen element to the p-type impurity element in the second p-type sublayer.
