Flat panel display device

A flat panel display device comprising:

• a first panel having a plurality of electron beam sources which are arranged in a matrix array, the electron beam sources being constituted of cathodes which emit electrons and control electrodes which are electrically insulated from the cathodes and control a quantity of electrons emitted from the cathodes, and a plurality of cathode lines and a plurality of control electrode lines which, in a state that the cathodes and the control electrodes which constitute respective electron beam sources are respectively separated into a plurality of sets, electrically connect the cathodes and the control electrodes for the respective sets, and making the electron beam sources designated by respectively selecting some of the cathode lines and the control electrode lines emit electrons, and
• a second panel having phosphors which emit light upon receiving the electrons emitted from the electron beam sources corresponding to the arrangement of the electron beam sources, wherein
• the cathodes and the control electrodes are arranged on the first panel such that out of a flat cross-sectional plane which is parallel to the second panel, a cross-sectional plane which is brought into contact with the cathodes and the control electrodes is present and, further, a cross-sectional plane which includes the control electrode lines differs from the cross-sectional plane which is brought into contact with the cathodes and the control electrodes.
