ABSTRACT:
A step of forming graphical symbols in an electroluminescent display device is performed by applying laser beams to a metal layer that is formed as a part of internal component formation of the display device. Powdery substances generated during the graphical symbol formation do not reach the internal components of the display device because they are sealed at the time of the graphical symbol formation.
