Abstract:
1. A nitride semiconductor light emitting device comprising: a substrate, an n-side nitride semiconductor layer and a p-side nitride semiconductor layer formed on said substrate, a light transmitting electrode formed on said p-side nitride semiconductor layer, a p-side pad electrode formed on said p-side nitride semiconductor layer for the connection with an outside circuit, and an n-side pad electrode for the connection of the n-side nitride semiconductor layer with the outside circuit, wherein a taper angle of an end face of at least one of said light transmitting electrode and said p-side nitride semiconductor layer is made smaller at an end portion than in other portions of said p-side semiconductor layer and light transmitting electrode by forming the end portion of said p-side semiconductor layer and light transmitting electrode in tapering-off planar shape such that the width of said p-side semiconductor layer and said light transmitting electrode decreases gradually to the distal end.
