Patent abstract
A method of manufacturing a high quality light emitting device is provided, in which light emitting elements having long life are manufactured by using light emitting elements having a structure that deteriorates less easily than conventional structures. After forming a bank, an exposed anode surface is wiped using a PVA (polyvinyl alcohol)-based porous medium, performing leveling and removal of debris. An insulating film is formed covering the bank and the anode, unevenness on the anode surface is covered, and the balance between the amount of holes and electrons injected into an organic compound layer can be regulated.
