<p>The surface of a coat material layer formed on an electrode is planarized, and at the same time, correct patterning is performed so as to uniformly form a film thereon. In an organic EL panel (100), a first electrode (11) is formed on a substrate (10), a pattern (20A) of an insulating wall (20) is formed on the substrate (10) so as to surround the surface to be coated on the first electrode (11), a coat material layer (14) is formed by applying a coat material onto the surface to be coated within the pattern (20A) of the insulating wall (20), an organic layer (13) including a light emitting layer is laminated on the coat material layer (14), and a second electrode (12) is formed on the organic layer (13). The insulating wall (20) has, on the inner surface of the pattern (20A), an overhung section (20B) which suppresses expansion of the coat material layer (14), an insulating wall (20) portion above the coat material layer (14) is deformed by heating and melting the insulating wall (20) after forming the coat material layer (14), and a tilted surface (22) or a curved surface (22A) which ensures continuity of the second electrode (12) is formed.</p> |
