Abstract

The present invention provides a display device allowing the quality and reliability to be improved by preventing the occurrence of vacuum leak attributable to dislocation which may be caused by preliminary baking and panel sealing. A display device in which the end surfaces of a support body 13 are hermetically bonded to a front substrate 2 and a rear substrate 1 by sealing members 4. In the display device, the support body 13 is formed by bonding together a plurality of support body members 13X1, 13X2, 13Y1 and 13Y2, and adjacent support body members are bonded by using a first bonding member 141 for bonding a central area of each bonding surface and a second bonding member 142 for bonding a marginal area around the central area. The softening temperature of the first bonding member is set higher than the softening temperature of the second bonding member.

Dependent claims

A display device comprising:

a front substrate which has an anode and phosphors on the inner side of the front substrate;
a rear substrate which has a plurality of electron sources on the inner side of the rear substrate and is arranged to face the front substrate with a certain distance;
a support body interposed between the front substrate and the rear substrate so as to surround a display region and maintain the distance between the front substrate and the rear substrate;
and
a sealing member which hermetically bonds the end surfaces of the support body to the front substrate and the rear substrate;
wherein the support body is formed by hermetically bonding a plurality of support body members by using a plural kinds of bonding members for bonding together the bonding surfaces of adjacent support body members, the plural kinds of bonding members being different in softening temperature from each other.
