ABSTRACT:
A fluorescent display device including a laterally elongated matrix-like display section and a plurality of control electrodes arranged in juxtaposition to each other while a longitudinal direction thereof is defined in a short side direction of the display section is disclosed which is capable of increasing a duty ratio when scanning the control electrodes. A plurality of picture cells are arranged longitudinally and laterally at equal intervals, resulting in forming the matrix-like display section. A plurality of sets of picture cells in an oblique direction are connected together. The control electrodes are connected together at every predetermined interval. Thus, when the control electrodes are scanned and the anode conductors are fed with a display signal, the fluorescent display device carries out graphic display while selecting desired picture cells at a high duty ratio.
