ABSTRACT:
The problem regarding volatileness of a solvent in an EL forming material, which occurs in adopting printing, are solved. An EL layer is formed in a pixel portion of a light emitting device by printing. Upon formation of the EL layer, a printing chamber is pressurized to reach a pressure equal to or higher than the atmospheric pressure, and the printing chamber is filled with inert gas or set to a solvent atmosphere. Thus the difficulty in forming an EL layer by printing is eliminated.
