Abstract
To provide a display device having the long lifetime and the high reliability by preventing the generation of a spark or a dark current between terminals of cathode lines and an anode, a shielding member is arranged between the terminals of the cathode lines and the anode so as to ensure shielding between the terminals and the anode.
Claims6
A display device comprising:
- a face substrate which has an anode and a fluorescent material on an inner surface thereof;
- a plurality of cathode lines which extend in one direction, are juxtaposed in another direction which crosses one direction, and has electron emitting sources;
- control electrodes which are constituted by arranging a plurality of strip-like electrode elements which cross the cathode lines in a non-contact state within a display region, extend in the above-mentioned another direction and are juxtaposed in one direction, and have electron passing apertures for allowing electrons from the electron emitting sources to pass therethrough toward the face substrate;
- a back substrate which has the control electrodes and the cathode lines on an inner surface thereof and faces the face substrate with a given distance therebetween;
- and
- a frame body which is inserted between the face substrate and the back substrate and is arranged around the display region to hold the given distance, wherein
- the cathode lines have extending one end sides thereof terminated outside the display region and inside the frame body, and a shield member is inserted between the terminals and the anode so as to ensure shielding between the terminals and the anode.
