Abstract

The present invention relates to a flip chip type nitride semiconductor light emitting device having p-type and n-type nitride semiconductor layers, and an active layer in between. The invention also has an ohmic contact layer formed on the p-type nitride semiconductor layer, a light-transmitting conductive oxide layer formed on the ohmic contact layer, and a highly reflective metal layer formed on the light-transmitting conductive oxide layer.
