Abstract
A semiconductor light emitting element includes: an n-type semiconductor layer; a super lattice structure layer formed on the n-type semiconductor layer and including repeatedly-formed first semiconductor layers and second semiconductor layers having a composition with a band gap greater than that of the first semiconductor layer; an electron injection control layer including a first control layer formed on the second semiconductor layer of super lattice structure layer and a second control layer formed on the first control layer; and an MQW light emitting layer formed on the second control layer and including repeatedly-formed barrier layers and quantum well layers. The first control layer has a composition with a band gap smaller than that of the second semiconductor layer of super lattice structure layer. The second control layer has a composition and a thickness same as or smaller than those of the quantum well layer of the MQW light emitting layer.
