Abstract
The present invention provides an image display device free of display defects and with high reliability to prevent destruction of electron sources due to injection of electric charge. On the outermost periphery of a display region, there are provided a bottom electrode 11 serving as data line, a scan line bus 21 serving as scan line, and dummy potential fixing electrodes 11D1, 11D2, 21D1 and 21D2 not contributing to image display, and these are connected with electrodes 70 and 80 with low impedance and constant potential.
Claims5
An image display device with a vacuum container, comprising thin-film type electron sources each placed at an intersection of a data line and a scan line crossing said data line via an insulation layer, a cathode substrate with said thin-film type electron sources arranged in form of matrix in a display region, a phosphor substrate having phosphor layers with a plurality of colors and an anode arranged to match each of the electron sources and a sealing frame to affix the two substrates together and interposed between said cathode substrate and said phosphor substrate around the display region, wherein:
- a potential fixing electrode connected to an electrode with low impedance and a constant potential on the outermost side of at least a pair of sides adjacent to said display region.
