Abstract
A semiconductor light-emitting element including a first semiconductor layer of a first conductivity type; a first light-emitting layer; a second light-emitting layer; and a second semiconductor layer of a conductivity type opposite to the conductivity type of the first semiconductor layer. The first light-emitting layer has a base layer with composition subject to stress strain from the first semiconductor layer and has a plurality of base segments partitioned into a random net shape; and a first quantum well structure layer composed of at least one quantum well layer and at least one barrier layer. The second light-emitting layer has a second quantum well structure layer composed of a plurality of barrier layers that have different compositions from that of the at least one barrier layer of the first quantum well structure layer, and at least one quantum well layer.
