ABSTRACT:
An FEC type fluorescent display device capable of carrying out a segment display of a small capacity. The fluorescent display device includes a substrate; a field emission cathode including a cathode electrode, an emitter and a gate electrode and arranged provided on an inner surface of the substrate for every display unit or digit; a front cover arranged opposite to the substrate for every digit; and a phosphor-deposited anode electrode arranged on an inner surface of the front cover for digit so as to face the field emission cathode. Any one of the cathode electrode, gate electrode and anode electrode is divided into a plurality of segments in a shape of a luminous display section for every digit, resulting in being a segmented electrode. Another one of the cathode electrode, gate electrode and anode electrode acts as a display selecting electrode corresponding to the display unit, resulting in a segment display being carried out.
