ABSTRACT:
A display device includes line cathodes. Separate first electrodes extend in rear of the line cathodes. A second electrode extends in front of the line cathodes and has apertures for guiding electron beams from the line cathodes. The apertures of the second electrode correspond to the separate first electrodes and the line cathodes. A third electrode deflects the electron beams. A screen is exposed to the electron beams. A vibration-preventing plate extends along the line cathodes and has apertures corresponding to the separate first electrodes and the line cathodes. The portions of the vibration-preventing plate between the apertures of the plate are in contact with the line cathodes.
