Abstract

PURPOSE: To maintain durability even in energization for a long period without causing inducting domain even in the case of frit-sealing, by using a specific copolymerization resinous substance in oriented film.
CONSTITUTION: Diamine compund, diamino monoalkoxy carbonyl amino compound, and tetracarboxylic acid dianhydride are caused to react in an organic solvent such as N-methyl-2-pyrolidone to generate a polymide-benzo imidazo pyrrolone copolymer resin in formula (where, Ar1: dimaino monoalkoxy carbonyl amino compound residual group; Ar2: diamine compound residual group; Ar3: tetracarboxylic acid dianhydride residual group). This solution is diluted to a proper concentration, and is spread on a glass substrate which is preliminarily coated with inorganic insulation film such as SiO2 in the upper layer or lower layer of electrode layer. The film after setting has excellent performance in loss starting temperature and heating loss characteristic, and frit-sealed after rubbing with cloth or the like.
