<p>PROBLEM TO BE SOLVED: To provide a flay type fluorescent display tube having a thin and wide displaying area. SOLUTION: In a flat type fluorescent display tube, it comprises a luminous part 140 comprising a phosphor film 142 and a transparent positive pole 141 arranged into a display surface 109 in a predetermined pattern, a electron emission part 120 constituted of a carbon nano tube having a pattern shape corresponding to a display pattern into which a substrate surface 101 opposing to the luminous part 104 is arranged and a predetermined potential is applied, an electron extraction electrode 125 arranged into the top of the electron emission part 120, and a plurality of supporting members arranged between the display surface 109 and the substrate 101. It is constituted by a supporting member 130 of a substrate side arranged by extending each supporting member from the substrate 101 into the display surface and contacts directly or via the electron extraction electrode the end of the supporting member 130 of the end of the substrate side with the supporting member 131 of the display surface side.</p> |
