ENVELOPE FOR DISPLAY AND METHOD FOR SEALING THE SAME

摘要

This invention provides an envelope for a display, which, even when used in an atmosphere which undergoes a temperature change, does not substantially cause any lowering in strength of a sealed part and has improved practical durability, and a method for sealing members constituting the envelope and a composition for sealing. The envelope for a display comprises two or more glass members constituting an envelope for a display which have been sealed through a sealing layer, and is characterized in that the sealing layer is formed of a sinter of a sealing material composed mainly of at least one compound selected from polyimide compounds and polyamic acid compounds and containing an inorganic oxide filler, the inorganic oxide filler is at least one filler selected from the group consisting of glass, silica, alumina and titania, and the alkali metal oxide is contained in an amount of not more than 1% by mass based on the inorganic oxide filler.
