ABSTRACT:
An anode plate 50 for use in a field emission flat panel display device comprises a transparent planar substrate 58 having a plurality of electrically conductive, parallel stripes 52 comprising the anode electrode of the device, which are covered by phosphors 54.sub.R, 54.sub.G and 54.sub.B. A substantially opaque, electrically insulating material 56 is affixed to substrate 58 in the spaces between conductors 52, acting as a barrier to the passage of ambient light into and out of the device. The electrical insulating quality of opaque material 56 increases the electrical isolation of conductive stripes 52 from one another, reducing the risk of breakdown due to increased leakage current. Opaque material 56 preferably comprises glass having impurities dispersed therein, wherein the impurities may include one or more organic dyes, selected to provide relatively uniform opacity over the visible range of the electromagnetic spectrum. Alternatively, the impurities may include the black oxide of a transition metal such as cobalt. Opaque material 56 is formed by mixing a TEOS solution with a dye or a source of metallic ions, spinning or spreading the mixture on glass substrate 58, and curing the mixture to drive out the organics and solvents. Two methods of fabricating anode plate 50 are disclosed.
