Patent ID: 7417379

Claim:
A cold cathode type flat panel display which is an image display device comprises 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 and an accelerating electrode is formed on the phosphor film, plural spacers for supporting the cathode substrate and the anode substrate at a given interval, and a glass frame for maintaining a 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, respective ones of the cold cathode type electron source being connected to one of the electrical lines in the line direction and one of the electrical lines in the row direction, the cold cathode type electron sources being line-sequentially scanned, and the accelerating electrode being supplied with an acceleration voltage, thereby displaying images, wherein some parts of 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 wherein some parts of the electrical lines positioned in the upper layer are made into spacer lines for giving a voltage lower than the acceleration voltage to the spacers, and further the spacers are in a substantially ground state by the spacer lines at least in a period when the scan lines adjacent thereto are selected.
