Abstract
A method of producing a gas discharge panel includes forming a surrounding unit by positioning a first panel and a second panel together with barrier ribs to partition the space between the panels into cells for light emission when charged with a plasma gas and appropriately addressed. An anti-sealing material inflow rib surrounds the barrier ribs. Sealing material is positioned outside the anti-sealing material inflow rib. The pressure inside the surrounding unit is adjusted to be lower than pressure outside the surrounding unit while applying heat to fuse the sealing material between the first panel and the second panel whereby sealing material is prevented from inflowing into the cells between the barrier ribs during production.
