To maximize the efficiency of utilization of mother substrates used as material for the substrates in the flat display panel to form a display screen, the flat display panel includes a display screen formed by tetragonal first and second substrates. Four sides or opposite two sides forming a tetragonal peripheral edge of the first substrate are rendered to be substantially equal to those of the second substrate, and the first and second substrate are sandwiched together with one of the first and second substrates protruding in part outwardly from the peripheral edge of the other of the first and second substrates.

In the manufacture of a gas discharge type display panel, by applying a sealing operation along with an exhausting operation, the sealing glassis broken down by a pressure difference between the inside and outside of the panel, and thus, the clearance gap between the substrates can be controlled as desired. In addition, the gaseous component that is unnecessary for the discharge operation is exhausted by setting the temperature of the amorphous sealing glass to exceed its softening-point and be no more than its working point. In the structure of the gas discharge type display panel, a protruding portion having a radius of curvature between 0.1 mm and 1 mm is formed on the sealing glass to reduce the dispersion in the thickness direction of the sealing glass, or the cross-sectional shape of the sealing glass is made convex both at its inside end part and its outside end part.

Gas discharge type display panel and production method therefor

A gas discharge display device comprising a front side substrate having a plurality of first electrodes and a back side substrate having a plurality of second electrodes, wherein at least said first electrodes or second electrodes are formed by wet etching using a resist made of an inorganic material, is excellent in the ability to suppress the breakage of wiring in electrodes.

A plasma display system has a plasma display panel including a pair of base plates for forming a plurality of discharge cells therebetween, and a plurality of pairs of electrodes for sustaining discharge to form plasma through a dielectric substance thereon in the discharge cells. The pairs of electrodes for sustaining discharge are disposed on a same one of the pair of base plates. The plasma display panel is configured such that a discharge current integrated over 40% of a discharge time Td from a start of the discharge time Td is smaller than a discharge current integrated over a remainder of the discharge time Td in one discharge, wherein the discharge time Td is defined as a time interval over which a discharge current does not drop to less than 5% of its maximum value in one discharge.

A manufacturing method for a gas discharge type display panel makes it possible to manufacture an environmentally friendly substrate with high accuracy and yet at low cost. According to the manufacturing methods electrodes are formed on a back substrate by photolithography or printing, then a glass paste is printed to a height of approximately 10 &mgr;m-500 &mgr;m by printing. A barrier rib blanks are produced by rolling under pressure the glass paste by using a roller provided with grooves. The roller is heated in advance. The barrier rib blanks are sintered into the barrier ribs.
