Problems solved by technology

If the surface of the electrode has unevenness, the film thickness of the organic layer deposited on it will become uneven, and light emission defects such as leakage will easily occur in the organic EL element.

Abstract

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.

Description

technical field [0001] The invention relates to an organic EL panel and a manufacturing method thereof. Background technique [0002] An organic EL element has a structure in which an organic layer including a light-emitting layer is laminated between a pair of electrodes, and an organic EL panel in which one or more organic EL elements are arranged on a substrate has an insulating structure that structurally or electrically divides the organic EL element things. As the insulating structure, there are insulating films for dividing electrodes formed on the substrate for each pixel, partition walls for separating electrodes formed on the organic layer, and the like. [0003] In such an organic EL element, the surface state of an electrode serving as a film-forming surface in an organic layer has a great influence on the quality of light-emitting characteristics. If the surface of the electrode has irregularities, the film thickness of the organic layer vapor-deposited thereo...
