Vacuum container, method of manufacture therefor, and flat image display apparatus provided with such vacuum container

Abstract

A vacuum container for a flat image display apparatus includes a rear substrate having an electron-emitting device mounted thereon, a face substrate arranged to face the rear substrate, having thereon a phosphor emitting light when the electron emitted from the electron-emitting device collides therewith, and an outer frame arranged between the dace substrate and the rear substrate. For this vacuum container, the outer frame is provided with a plurality of frame members. With the structure thus arranged, this vacuum container contributes significantly to manufacturing a light weight, but highly robust flat image display apparatus at lower cost. By providing a plurality of frame members for the outer frame portion, thinner substrates can be utilized with a good sealing mechanism, while securing the sufficient robustness of the edge circumference of the vacuum container.
