ABSTRACT:
A fluorescent display device is disclosed which is capable of improving visibility of luminous display of anodes. In the device, cathodes are arranged laterally out of an area opposite to the anodes so as not to hinder the observation of the luminous display. The device also includes a deflecting electrode for deflecting and diffusing electrons emitted from the cathodes so as to direct them toward the anodes.
