Abstract
The construction of the dielectric layer of a panel used in making a gas panel display by an E-gun evaporation process in the same evacuated chamber that deposits an electron-emissive layer on the panel so as to obtain increased efficiency in the fabrication and improved operating characteristics of the gas panel. Stress free dielectric layers are obtained by E-gun evaporating borosilicate glass from a molten pool of borosilicate having an area of at least 2cm.sup.2 up to about 10cm.sup.2 with the substrate for the layers being maintained at from 200.degree. C to 300.degree. C and the evaporation rate being 40 to 80 A/sec. at approximately 10 inches from the molten pool.
