PURPOSE:To obtain a planar cathode-ray tube having excellent deflection sensibility by arranging plural linear cathodes elongated in vertical direction in horizontal direction then arranging the vertical scan electrode on the backface while the modulation electrode, vertical and horizontal deflection electrodes on the front face. CONSTITUTION:Plural linear cathodes 10 elongated in vertical direction are arranged in horizontal direction on the fluorescent screen 27 while electrically splitted vertical scan electrodes 12 of 1/n of the horizontal scanning lines are provided on the backface while crossing perpendicularly with the cathode 10. While electron beam modulation electrodes 13 corresponding one by one with the cathodes 10, face electrodes 14, 15, 16, vertical deflection electrodes 17, 18 having shifted electron beam pass holes and horizontal deflection electrodes 19-21 splitted into plural number in beam advancing direction are provided on the front face. It is contained in a vacuum housing to form a flat-type cathode ray tube. Consequently, the deflection sensibility can be improved through simple structure resulting in considerable improvement of performance.
