ABSTRACT:
A display device capable of decreasing the number of drivers required for driving electrodes, decreasing the number of filamentary cathodes to reduce power consumption and utilizing electrons with high efficiency. In the display device, filamentary cathodes are arranged in parallel with control electrodes and in a manner to interpose two or more control electrodes between each adjacent two filamentary cathodes. Also, each deflecting control electrode is constituted by adjacent two control electrodes positioned right below each of the filamentary cathodes and scanned while being applied thereto a potential by way of a deflecting circuit. Further, to the control electrodes other than the deflecting control electrodes is constantly applied a potential negative with respect to the filamentary cathodes.
