Abstract
The present invention ensures the hermetic bonding of a support body which is interposed between a face substrate and a back substrate and is formed of a plurality of members thus easily realizing the large-sizing of a screen of a display image and, at the same time, enhancing a hermetic property holding function of the image display device. A support body is interposed between a face substrate and a back substrate while surrounding a display region and hermetically seals both substrates using a sealing material. The support body is formed by hermetically bonding a plurality of support body members each other using a bonding material which has a softening point higher than a softening point of the sealing material.
Claims6
An image display device comprising:
- 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, wherein
- end surfaces of the support body and the face substrate and the back substrate are hermetically sealed respectively using a sealing material, and
- the spacers are fixed to the substrate using a fixing material, and
- the support body is constituted of a plurality of support body members, and the support body members are hermetically bonded to each other using a bonding material, wherein
- a softening temperature of said bonding material is higher than a softening temperature of said sealing material,and a fixing temperature of said spacers is higher than a softening temperature of said sealing material.
