EL device and method for manufacturing the same

摘要

Formed on a glass substrate (1) is an EL element (2) including an anode (3), an organic light emitting layer (4), and a cathode (5). A first protective film (6) is formed on a surface of the EL element (2) to cover the EL element (2) through a dry process. A second protective film (7) is then formed on a surface of the first protective film to cover the first protective film by using polysilazane through a wet process. Even if an uncovered portion is left in the first protective film owing to the existence of a foreign matter thereon, the second protective film covers the uncovered portion to avoid intrusion of oxygen or other gases, moisture, etc. into the EL element from the outside.
