发明名称 Vacuum flourescent display apparatus
摘要 To provide a vacuum fluorescent display apparatus that can be expected to enhance lifespan characteristics of a red phosphor that does not contain Cd when driven in a voltage range of 30V or above. A vacuum fluorescent display apparatus comprising a filament cathode (10) and an anode (7); the filament cathode being arranged in a vacuum container, and used for releasing low-energy electrons; the anode having a phosphor (8) adhering thereto, and being struck by the low-energy electrons and thereby caused to emit light; wherein a structural body (9) is provided to a region in which the low-energy electrons released by the cathode can be controlled; the structural body having an electrically conductive or semi-conductive metal oxide formed at a portion that is bombarded by low-energy electrons.
