Abstract

PURPOSE: To form a physically and chemically stable oriented insulating film on cell substrate by lapping an insulating film obtd. by primarily calcining a film based on an org. Si compound or an org. Ti compound at a low temp. and by secondarily calcining the lapped film.
CONSTITUTION: A thin film of a covering agent based on an org. Si compound such as tetraalkyl silicate or an org. Ti compound such as tetreaalkyl titanate is formed on an electrode substrate having a transparent electrode and calcined at about 250W 300°C to form an insulating film made of silicon oxide or titanium oxide. This film is then oriented by lapping with cotton cloth in a fixed direction, and the oriented film is secondarily calcined at about 450W500°C to obtain physically and chemically stable insulating film of high hardness.
