Abstract
A method for manufacturing hollow spacers includes forming an elongated tube from sheets of material, and then separating a transverse segment of a desired thickness from the tube to form a spacer. For forming spacers for a field emission display, the sheets can be glass and the adhesive can be glass frit paste. The tube can be segmented by attaching the assembled tube to a support piece and then saw cutting the tube.
