ORGANIC ELECTROLUMINESCENT PANEL, AND MANUFACTURING METHOD AND APPARATUS THEREOF

摘要

PROBLEM TO BE SOLVED: To extend a pot life of a sealing substrate using a thermosetting adhesive so as to continuously manufacture organic electroluminescent panels by using long substrates, increase productivity, and stably manufacture the organic electroluminescent panels by suppressing variations in quality at start and end of production.SOLUTION: A sealing structure of an organic electroluminescent panel is formed by bonding a long element substrate having organic electroluminescent elements on a surface thereof and a long sealing substrate having a sheet-like adhesive layer constituted of a thermosetting resin on a surface thereof. A manufacturing method for the organic electroluminescent panel comprises the steps of: feeding the sealing substrate which is wound on a roll; and bonding the element substrate and the sealing substrate so as to form a multilayer substrate. In the feeding step, the sealing substrate to be fed is cooled down to a room temperature or below. It is a further object of the present invention to provide a manufacturing apparatus for manufacturing the organic electroluminescent panel.
