Abstract
A planar display apparatus with a fluorescent screen formed on the inner surface of a front panel in a planar tube body. An electron gun is disposed at a position deviated in a vertical scanning direction from a region opposite the fluorescent screen, and a vertical deflecting electrode composed of a plurality of parallel electrodes is disposed at an opposite portion relative to the fluorescent screen on the side of a back panel opposed to the front panel of the planar tube body. In a space between the vertical deflecting electrode and the fluorescent screen, there is disposed an electrode structure having at least an electron lens scanning electrode composed of a plurality of parallel electrodes, a splitting electrode for splitting an electron beam from the electron gun into a plurality of beams, a modulating electrode, and horizontal deflection electrodes.
