Abstract
A method of fabricating an anode plate 80 for use in a field emission device comprising the steps of providing a substantially transparent substrate 70, depositing a layer of a transparent, electrically conductive material 90 on a surface of the substrate, and then removing portions of said layer of conductive material to leave stripes of said conductive material 90.sub.R, 90.sub.G, 90.sub.B. The stripes of conductive material have a first and second corner 84, 88 distal from the substrate 70. The first and second corners 84, 88 of the stripes of conductive material are rounded and luminescent material 74 is applied on the conductive stripes 90. The first and second corners 84, 88 are rounded by applying voltage to the stripes 90 and then etching the stripes to form the rounded corners 84, 88.
