Abstract

PURPOSE: To maintain durability even in energization for a long period without causing inducing domain even in the case of frit-sealing, by using a specific poly- merization resinous substance in oriented film.
CONSTITUTION: 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 polyimide-benzo imidazo pyrrolone polymer resin in formula (where, Ar1: diamono monoalkoxy carbonyl amino compound residual group; Ar2: 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 an inorganic insulation film such as SiO2 in the upper layer or lower layer of electrode. The film after setting has excellent performance in loss starting temperature and heating loss characteristic, and is frit-sealed after rubbing with cloth or the like.
