Abstract
A method of fabricating an anode plate 18 for use in a field emission device comprising the steps of providing a transparent substrate 20 and depositing a layer of a transparent, electrically conductive material 24 on a surface of the substrate. Next, portions of the layer of conductive material 24 are removed to form regions of the conductive material. Luminescent material 26 is then applied to the conductive regions 24, and a layer of electrically conductive material 23 is applied to the luminescent material 26. Outer portions of the conductive material 23 and an outer portion 27 of at least some of the particles 25 of the luminescent material are thereafter removed.
