Patent ID: 6958570

Claim:
A display device comprising: a front substrate having an anode and fluorescent materials on an inner surface thereof; a back substrate having a plurality of cathode lines, which extend in a first direction, are arranged in parallel in a second direction which crosses said first direction and include electron sources, and plate member control electrodes, which are formed 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 said second direction, are arranged in parallel in said first direction and have electron passing apertures which allow electrons from the electron sources to pass therethrough to the front substrate side, on an inner surface thereof, the back substrate being arranged to face the front substrate in an opposed manner with a given gap therebetween; an outer frame for maintaining the given gap, which outer frame is interposed between the front substrate and the back substrate and surrounds the display region; and an inner frame which is arranged outside the display region and inside the outer frame and fixes both end regions of the strip-like electrode elements which constitute the plate member control electrodes to the back substrate.
