Abstract
A fluorescent display device includes a front glass at least part of which is translucent, a substrate, a cathode, an electron-emitting layer, an electron extracting electrode, a phosphor film and an anode, and a conductive layer. The substrate is formed of an insulating member arranged to oppose the front glass. The front glass and the substrate constitute part of a vacuum envelope. The cathode is disposed on the substrate. The electron-emitting layer includes a carbon nanotube and is formed on a surface of the cathode. The electron extracting electrode is arranged between the substrate and the front glass to be spaced apart from the cathode. The phosphor layer and the anode stack on a surface of the front glass which opposes the substrate. The conductive layer is formed between the cathode and the substrate.
