COLD CATHODE ELECTRIC FIELD ELECTRON-EMITTING ELEMENT AND METHOD FOR PREPARING THE SAME, AND METHOD FOR PREPARING COLD CATHODE ELECTRIC FIELD ELECTRON-EMITTING ELEMENT DISPLAY

摘要

PROBLEM TO BE SOLVED: To manufacture simply the cold cathode electric field electron-emitting element having a high electron-emitting efficiency. SOLUTION: A cathode electrode 11A is formed on a support 10, an insulation layer 12 is formed on an entire plane, a gate electrode 13 is formed on the insulation layer 12, an opening 15 with exposed cathode electrode 11A on a bottom is formed on at least the insulation layer 12, and an electron-emitting electrode 17 comprising a conductive composition having a longer axis and a shorter axis dispersing conductive particles having a shape magnetic anisotropy with a dispersant is formed, and the conductive particles are oriented in a direction that the longer axis of the conductive particles crosses an electron irradiation surface (the surface of fluorescent material layer 22) by positioning an electrode-emitting electrode 17 in a magnetic field in a state that the conductive composition has a fluidity.
