Abstract:
A nitride semiconductor light emitting device comprising a n-type cladding layer, a p-type cladding layer and an active layer including a first nitride semiconductor layer containing In between said n-side cladding layer and said p-side cladding layer, wherein said n-side cladding layer is a super lattice structure layer comprising first nitride semiconductor layers and second nitride semiconductor layers containing Al and has a total thickness of not less than 0.5 .mu.m wherein an average composition of Al in said n-side cladding layer is set in a way that the product of said average Al composition in % contained in said n-side cladding layer multiplied by the thickness in .mu.m of said n-side cladding layer is 4.4 or more.
