Patent ID: 7385355

Claim:
A cold cathode type flat panel display which is an image display device comprising a vacuum panel container composed of a cathode substrate in which plural cold cathode type electron sources are arranged at regular intervals, an anode substrate in which a phosphor film is deposited in the form of dots or lines so as to be opposed to the electron sources, plural spacers for supporting the cathode substrate and the anode substrate at a given interval, and a glass frame for keeping vacuum, plural electrical lines which extend in a line direction and a row direction which cross each other being formed, across an interlayer insulator, on the cathode substrate, the cold cathode type electron sources being arranged at positions corresponding to intersection coordinates of these electrical lines so as to be connected to the electrical lines in the line direction and the row direction, and the cold cathode type electron sources being line sequentially scanned, thereby displaying images, wherein lines positioned in an upper layer out of the plural electrical lines are made into scan lines and lines positioned in a lower layer out of the plural electrical lines are made into data lines, and some parts of the scan lines positioned in the upper layer function both as power feeding lines for giving electric potential to the spacers and scan lines, and are at scan line voltage at the least in a period when the parts of the scan lines are selected, and the cold cathode type electron sources each have a structure wherein a bottom electrode, an electron accelerator, and a top electrode are laminated in this order, and are each an electron source element which emits electrons from the surface of the top electrode when a positive voltage is applied to the top electrode, an upper surface of an upper bus electrode having a material with oxidization resistance.
