Abstract
A nitride semiconductor light emitting device includes a substrate, an n-type nitride semiconductor layer formed on the substrate and provided with an electrode region of a predetermined area adjacent to a center of one lateral side of the top surface of the substrate, an n-type electrode formed on the electrode region, an activation layer, a p-type nitride semiconductor layer, and a p-type electrode which has a bonding pad adjacent to a center of another lateral side opposite to the lateral side adjacent to the electrode region to have a predetermined space from the n-type electrode and a band-shaped extension connected to the bonding pad to extend along a lateral side of the top surface of the p-type nitride semiconductor layer in opposite directions from a connected portion of the extension with the bonding pad.
