METHOD FOR PRODUCING GLASS SUBSTRATE WITH SEALING MATERIAL LAYER

摘要

PROBLEM TO BE SOLVED: To provide 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 1 with a sealing material layer includes the steps of: preparing a glass substrate 11; applying a first sealing material paste to the glass substrate 11 and then forming a first sealing material film 12; applying a second sealing material paste to the first sealing material film 12 and then forming a second sealing material film 13; and firing the obtained laminated film to form a sealing material layer 14 on the glass substrate 11. The first sealing material paste contains the first sealing material, and the second sealing material paste contains the second sealing material. The content of a refractory filler in the second sealing material is less than the content of the refractory filler in the first sealing material.
