Abstract
An airtight envelope for an FED capable of ensuring formation of a gap or internal space therein with high accuracy and preventing leakage thereof and a decrease in display area. An anode substrate having a phosphor-deposited display pattern formed thereon and a cathode substrate having an electron emission source formed thereon are sealed joined to each other using a sealing material, to thereby provide an airtight envelope for an FED. The substrates are provided at a portion thereof joined together with particulate or bar-like elements which are kept unmelted or substantially unsoftened. Also, spacers are arranged at positions in a gap between the anode substrate and the cathode substrate which do not interfere with a display by the FED.
