With the aim of progressing toward Society 5.0, research developments in versatile light-emitting devices, which seamlessly connect us with all types of information, are rapidly being made. In this direction, devices using powder electroluminescence, which can be generated by the flat light-emission through electric field excitation, have attracted considerable attention from researchers around the world, because such devices offer excellent environmental resistance and can be fabricated using only a printing process. This paper reviews the latest research developments on powder electroluminescent devices.
