Patent ID: 7192327

Claim:
A method of manufacturing a plurality of spacers in an image display device that comprises a first substrate having a phosphor surface, a second substrate opposed to the first substrate with a gap and having a plurality of electron sources configured to emit electron beams to excite the phosphor surface, the plurality of spacers being made of insulating material, arranged between the first substrate and the second substrate and supporting an atmospheric load acting on the first and second substrates, the method comprising: forming spacers by using insulating material; applying paste or solution, either containing an electrically conductive component, to at least one of distal end portions of each spacer, and causing the paste or solution to permeate into the distal end portion by virtue of capillary action; and firing each spacer into which the paste or solution has permeated, thereby providing a spacer that has, at at least one of the distal end portions, a conductivity-imparting portion impregnated with electrically conductive material.
