Conventionally, there are problems that high resolution is difficult to be
achieved since an extreme narrow width bank can not be formed and an
aperture ratio as a light-emitting device is low. In addition, there is a
threat of electrostatic discharge damage or adhesion of dust during the
transportation of a substrate provided with an anode into the equipment
for depositing EL material. In view of the foregoing, a first bank formed
of an inorganic insulating film is formed, and an insulating film is
formed thereon, then, a second bank in contact with a side face of the
first bank by carrying out etch back, and then, a side wall bank is
formed. For preventing electrostatic discharge damage, an antistatic
layer is formed, and the substrate is transported, then, the antistatic
layer is removed to form the second bank.
