Abstract
A glass spacer for an electron-beam emitting display device is composed of non alkaline glass having almost the same linear expansion coefficient as that of soda-lime-silica glass. The glass includes SiO with 10 to 35 percent by mass, RO, in which “R” refers to an alkaline earth metal, with 20 to 60 percent by mass, B O with 9 to 30 percent by mass and Al O with 0 to 10 percent by mass, and which is substantially free of alkali. The linear expansion coefficient of the glass spacer is in a range from 76×10 /° C. to 92×10 /° C. The glass spacer may further include La O with 0 to 30 percent by mass, ZnO with 0 to 8 percent by mass and TiO with 0 to 5 percent by mass.
