Abstract:
A method of manufacturing an electron source, said method comprising the steps of:(a) providing a substrate having thereon row-direction wiring lines, and column-direction wiring lines, and a plurality of electron emissive portion formation thin film elements arranged in matrix formation on said substrate, wherein respective thin film elements in respective rows of said matrix formation are connected between respective column-direction wiring lines and a common respective row-direction wiring line, and respective thin film elements in respective columns of said matrix formation are connected between respective row-direction wiring lines and a common respective column-direction wiring line; and(b) performing an energization forming treatment to form an electron emissive portion in each thin film element, in order to produce respective surface conduction type electron emissive elements, by applying voltage to selected row-direction and column-direction wiring lines whereby forming voltages are applied across the thin film elements connected between said selected wiring lines;wherein in step (a), a respective non-linear element is provided in series with each respective thin film element in the connection of that respective thin film element between respective row-direction and column-direction wiring lines; andin step (b), the non-linear elements in series with the thin film elements, other than those thin film elements connected between said selected wiring lines, prevent a forming voltage being applied across the thin film elements in series therewith.
