In a field emission display device, a spacer assembly and a method for forming a spacer assembly. In one embodiment, the present invention is comprised of a spacer wall which has a specific secondary electron emission coefficient function associated therewith. In the present embodiment, a coating material is then applied to at least a portion of the spacer wall.
