Patent ID: 7141130

Claim:
A method of manufacturing a glass panel comprising a pair of glass plates opposed to each other; spacers disposed between said pair of glass plates for maintaining a gap therebetween; and a sealing member having a lower melting point than said glass plates for sealing said pair of glass plates at outer peripheries thereof to form a decompression void between said pair of glass plates, said method comprising the steps of: applying said low melting point sealing member to said outer peripheries of said pair of glass plates in a melted condition; causing said sealing member to start hardening from an outer surface thereof exposed to the atmosphere by lowering an atmospheric temperature; and causing said pair of glass plates to start cooling from outer surfaces thereof to apply a compressive force to said glass plates; wherein said glass plates have a compressive force at outer surfaces of the outer peripheries thereof exposed to the atmosphere, with said decompression void being in atmospheric condition, so that an area of said glass plates between said sealing member and an outermost one of said spacers is formed concave toward said decompression void.
