Specifically, the light extraction efficiency is improved by converting the transparent electrode waveguide mode to the radiation mode in which the light is radiated from the transparent electrode to the transparent substrate, or by converting {TAIL ~ the transparent substrate} {HEAD ~ waveguide mode} to the radiation mode in which the light is radiated outside from the transparent substrate
