Abstract
Abstract A method for fabricating a plasma display includes forming an organic film on a pattern of discharge electrodes and preheating to a temperature lower than a temperature at which the organic film undergoes an exothermic phenomenon, for a given time. By this, in the firing treatment after application of an insulating material in between organic films, a gentle change in shape of the organic film during the process of burning off the organic film is effective in suppressing a change in shape of barrier ribs formed by the insulating material.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
92 words
A method for fabricating a plasma display which comprises the steps of: forming a given pattern of discharge electrodes on a transparent plate; forming organic films on the discharge electrodes so that grooves are established between adjacent discharge electrodes; pre-heating said organic films at a temperature lower than that at which the organic films undergo an exothermic phenomenon, for a given time; filling an insulating material into each said groove between adjacent organic films; and firing the insulating material at a temperature higher than the pre-heating temperature to remove the organic film.
Claim 2
Independent Claim
92 words
A method for fabricating a plasma display which comprises the steps of: forming a given pattern of discharge electrodes on a transparent plate; forming organic films on the discharge electrodes so that grooves are established between adjacent discharge electrodes; pre-heating said organic films at a temperature lower than that at which the organic films undergo an exothermic phenomenon, for a given time; filling an insulating material into each said groove between adjacent organic films; and firing the insulating material at a temperature higher than the pre-heating temperature to remove the organic film.
Claim 3
Dependent Claim
45 words
A method according to claim 1, wherein said insulating material is a glass paste which comprises a first glass component which is softened during the pre-heating step and another glass component which is softened in the vicinity of the firing temperature of the organic film.
Claim 4
Independent Claim
98 words
A method for fabricating a plasma display which comprises the steps of: 21 forming a given pattern of discharge electrodes on a transparent plate; forming an organic film on the discharge electrodes; pre-heating the organic film at a temperature lower than a temperature, at which the organic film undergoes an exothermic phenomenon, for a given time; applying a glass paste in each grooves formed between adjacent organic films a plurality of times so that the glass paste is gradually formed to a predetermined height; and firing the glass paste during which the organic film is removed by burning.
