Abstract
An optical panel having superior environment resisting properties is provided. An increase in electrical resistance is prevented by heat treating the electrode in a vacuum at a temperature between about 200.degree. and 600.degree. C. Electrolytic corrosion resistance of the panel is provided by coating at least the non-conductive portions of the terminal portions of the panel with a water-repellant material.
