An improved vacuum fluorescence display (VFD) that is less expensive to produce and more rugged than currently available VFDs. The display includes metal side walls and fluorescent material carried on one or more silicon wafers. A ceramic, layerable insulating material is employed as the substrate on which the wafer or wafers are mounted. In another embodiment of the current invention, a chemical getter is incorporated into a recess formed in the ceramic substrate. The getter is positioned underneath the back side of the phosphor screen so as to significantly reduce contamination of the screen by material sputtered off of the surface of the getter.
