ABSTRACT:
A thin flat panel display is formed from two substrates uniformly spaced apart by a plurality of spacer members. The spacer members are formed into bundles, held together by binder material, and sliced into a plurality of thin discs. One opposing face of one of the substrates is provided with patterned arrays of first and second arrays of different adhesives. The discs are placed on the adhesives and processed to activate the adhesives, remove the binder and the second adhesive thereby reducing the number of spacers remaining in the assembly to only those adhered by the first adhesive. The second substrate is then juxtapositioned on the first substrate assembly and bonded thereto.
