ELECTRON-EMITTING DEVICE COLD CATHODE FIELD EMISSION DEVICE AND METHOD FOR PRODUCTION THEREOF AND COLD CATHODE FIELD EMISSION DISPLAY AND METHOD FOR PRODUCTION THEREOF

摘要

PURPOSE: An electron emission device, cold cathode field emission element and production method for the same, and Cold cathode field emission display device and production method for the same is provided to achieve a significantly high electron emission efficiency by permitting electron emission to be performed at a low electric field. CONSTITUTION: A cold cathode field emission element comprises a cathode electrode(11) formed on a supporting layer(10); and a conical electron emission unit(15) made up of a carbon, and formed onto the cathode electrode. Selectively, an electron emission unit forming layer(50) made of a metallic thin film is formed between the cathode electrode and the electron emission unit.
