Abstract

A semiconductor device is formed in a self-light-emitting apparatus having a substrate and a plurality of self-light-emitting elements formed on the substrate. The semiconductor device is used to drive one of the self-light-emitting elements. The semiconductor device includes an active layer of semiconductor material, in which a source region and a drain region are formed. A source electrode has a multi-layered structure including an upper side layer of titanium nitride and a lower side layer of a high melting point metal having low resistance. The source electrode is electrically coupled to the source region. A drain electrode has a multi-layered structure including an upper side layer of titanium nitride and a lower side layer of a high melting point metal having low resistance. The drain electrode is electrically coupled to the drain region. An insulation layer is formed on the active layer. A gate electrode is formed on the insulation layer.
