In a field emission type image display panel, plural cathode electrodes are formed in a stripe shape on a first substrate and each having emitters for field emission. Cathode lead-out electrodes supply signals to the cathode electrodes. Plural patch-like gate electrodes are arranged in a matrix form over the plural cathode electrodes and insulated from the plural cathode electrodes. Gate lead-out electrodes are led out along spaces between adjacent two rows in rows formed of patch-like gate electrodes substantially perpendicular to the cathode electrodes, each of the gate lead-out electrodes being connected to the patch-like gate electrodes in adjacent two rows in a zigzag arrangement and every other gate electrode. A second substrate is spaced from the first substrate a predetermined distance apart. Plural patch-like anode electrodes are arranged on the second substrate, the plural anode electrodes respectively confronting the plural patch-like gate electrodes in a matrix form. Fluorescent materials are formed over the plural patch-like anode electrodes, for displaying an image. Anode electrodes are led out along spaces between adjacent two rows of anode electrodes substantially perpendicular to the cathode electrodes, each of the anode lead-out electrodes being connected to anode electrodes in adjacent two rows in a zigzag arrangement and every other anode electrode.
A magnetic matrix display device has a grid electrode in which differing first grid (G1) and second grid (G2) apertures are used. A sensor element and a second grid electrode are combined as a single structure. Other aspects of the invention relate to a deflection anode having reduced capacitance, the use of a polyimide coating for the grid electrodes, the use of a compliant mounting and adjustment for a grid assembly and the provision of an illuminated border on a magnetic matrix display.
An image display device which prevents damage to an electron-emitting device from discharge between a faceplate and a rear plate is provided. A conductive plate 12 including a transparent conductive film is formed over a surface of a substrate 11, a distance specifying member 13 having a plurality of openings is formed on the conductive area 12, a fluorescent material 14 is arranged in the opening, and a conductive film 15 is arranged on the fluorescent material 14 to for a face plate. A resistance R.sub.x between the adjacent conductive films 15 is set larger than a resistance R.sub.z, between the conductive film 15 and the conductive area 12. Discharge current generated between each conductive film 15 and a rear plate 21 is caused to flow into the conductive area 12 by applying anode voltage to the conductive area 12, which suppresses influence on an electron-emitting device 23.
