Abstract
An improved cathodoluminescent device with a one piece spacer structure which is rigidly connected to two sets of grid electrodes. The spacer structure defines holes therein that spatially match pixel dots on an anode on a face plate. One set of grid electrodes comprises layers of electrically conductive material on surfaces within at least some of the holes of the spacer structure. The two sets of grid electrodes and different spacer layers may be attached together to form a one piece spacer structure integral with the two sets of grid electrodes. The display device is then simply assembled by matching each of the holes of the spacer structure with a pixel dot on the face plate, and attaching the structure to the face plate and a back plate.
