| 1. A cold cathode field emission display comprising a cathode panel having a plurality of cold cathode field emission devices
and an anode panel which are bonded to each other in their circumferential portions,
wherein:
the anode panel comprises a substrate, a phosphor layer formed on the substrate, one electric supply line, and an anode electrode
formed on the phosphor layer,
the anode electrode is constituted of anode electrode units in the number of N (N≧2),
each anode electrode unit is connected to an anode-electrode control circuit through said electric supply line, and
VA/Lg<1 (kV/μm) is satisfied in which VA (unit:kilovolt) is a voltage difference between an output voltage of the anode-electrode control circuit and a voltage applied
to the cold cathode field emission device, and Lg (unit:μm) is a gap length between the anode electrode units.
