A LED has a thin highly resistive or insulative layer formed below an electrode
pad in order to divert current flow from the region below an electrode pad, which
region does not contribute to light emission, to another region which does. Consequently,
better current efficiency is obtained. Further, diverting current flow from the
region below the electrode pad where mechanical damages are expected deters deterioration
of the region. Consequently, the LED lasts longer and is a better quality product.
