ABSTRACT:
A graphic fluorescent display device is disclosed which is capable of effectively eliminating a streak pattern occurring right below cathodes. The fluorescent display device is constructed in such a manner that an electric field controlling electrode is disposed on the surface of a cover plate opposite to a substrate having anodes formed thereon, and potential positive with respect to the cathodes is applied to the electric field controlling electrode so that electrons emitted from the cathodes may be diffused by the positive electric field of the electric field controlling electrode.
