Patent ID: 7470610

Claim:
A method of fabricating an organic electroluminescent device comprising the steps of: (1) preparing a substrate on which a first electrode has been formed and forming a laminated film by laminating an organic layer comprising a luminescent layer and a second electrode on the first electrode in this order; (2) forming a first sealing film which covers a whole region of the laminated film; (3) forming on a surface of the first sealing film a second sealing film having an opening pattern, wherein the first sealing film and the second sealing film are formed of different film thicknesses; and (4) patterning the first sealing film by dry-etching the first sealing film using the second sealing having the opening pattern as a mask, wherein the first sealing film is patterned utilizing the difference between the film thicknesses of the first sealing film and the second sealing film.
