METHOD FOR PRODUCING GLASS SUBSTRATE WITH SEALING MATERIAL LAYER

摘要

PROBLEM TO BE SOLVED: To improve the long-term reliability of an organic EL device or the like by providing a method for producing a glass substrate with a sealing material layer which can be sealed with a low-power output laser.

SOLUTION: The method for producing a glass substrate with a sealing material layer includes the steps of: preparing a glass substrate; applying a first sealing material paste to the glass substrate and then forming a first sealing material film; applying a second sealing material paste to the first sealing material film and then forming a second sealing material film; and firing the obtained laminated film to form a sealing material layer on the glass substrate. The first sealing material paste contains a first glass powder; the second sealing material paste contains a second glass powder; and the softening point of the second glass powder is lower than the softening point of the first glass powder.
