Abstract
PURPOSE: To obtain always bright fluorescent display by arranging a highly resistant film, which had a specific resistance value, between a segment anode and antielectrification layer, on the upper surface of insulating film, and by eliminating the influence of, the external electric field.
CONSTITUTION: A high resistance film 18 is arranged in a coated form so that the resistance value of substancially 1W105MΩ or preferably of 10W103MΩ is attained between an antielectrification layer 14 and a plurality of segment anodes 5 on the upper surface of a insulating film 3, and on the upper surface of, said film 18 a plurality of anodes 5 and layers 4 are arranged in coated forms. Accordingly, the film 18 shields out the external electric field penetrating through the undersurface of the base plate 1 and electrons which flow from cathode 9 to anode 5. Even if electrons collide with the slit part 15 between the anode 5 and the layer 14, said electrons are flowed into the anode 5 and the layer 14 without causing electrification, and the disturbance of the electron flow generated by the electrification at the slit part 15 is suppressed. Thus, bright fluorescent display can be always obtained.
