Abstract
A flat image display device includes two substrates located opposite each other with a gap therebetween and a vacuum seal portion which seals a predetermined position on the substrates and defines a sealed space. The vacuum seal portion has a sealing layer which is formed of a sealing material filled along the predetermined position. The sealing material having a melting point of 400° C. or less and a rate of contraction during solidification ranging from +0.5% to −2.5%.
