Display Device and Method of Manufacturing Same

A manufacturing method of an image display device having

• a face substrate which forms an anode and a phosphor on an inner surface thereof;
• a back substrate which forms a plurality of electron sources on an inner surface thereof and faces the face substrate with a given distance therebetween;
• a support body which is interposed in a state that the support body surrounds a display region between the face substrate and the back substrate;
• and
• a plurality of spacers which maintain the distance between the face substrate and the back substrate within the display region, and
• end surfaces of the support body and the face substrate and the back substrate being hermetically sealed respectively using a sealing material, and the spacers and the substrate being fixed using a fixing material, comprising:
• constituting the support body of a plurality of support body members,
• interposing the support body between the face substrate and the back substrate,
• hermetically bonding the support body members to each other using a bonding material, and, thereafter,
• hermetically sealing the face substrate, the back substrate and the support body using the sealing material, and fixing the substrate and the spacers using the fixing material, wherein
• a softening temperature of said bonding material and a softening temperature of said sealing material are different, and a softening temperature of said bonding material and a fixing temperature of said spacers are different.
