Abstract: A manufacturing method of carbon nanotube thick membrane by controlling calcination conditions while excluding surface treatment process and a field emission display using the method are provided to increase field emission and to complete carbon nanotube sharply. A manufacturing method of carbon nanotube thick membrane comprises steps of: (a) preparing carbon nanotube paste containing carbon nanotube, organic binder, organic solvent and inorganic powder or filler of low-melting point metal powder; (b) forming thick membrane on the electrode of the substrate by screen-printing or inkjet-printing the carbon nanotube; (c) after subjecting the substrate inside the heat-treatment equipment, heat-treating the substrate for removing organic solvent; and (d) furnishing air and inert gas in the ratio from 2:8 to 8:2 with the substrate which is out of organic solvent, and calcinating the substrate at the temperature of 350-500deg.C. In step (a), the organic binder is selected from a group consisting of ethylcellulose, acrylic resin and mixture thereof, the organic solvent is selected from a group consisting of terpineol, butyl carbitol acetate and mixture thereof, and the filler is selected from a group consisting of glass frit, indium tin oxide, indium dioxide, tin dioxide, zinc oxide, sliver, lead, zinc, tin and magnesium. The substrate in step (b) is glass or ceramic, and the electrode is selected from a group consisting of tin oxide, gold, silver, copper and aluminium. The temperature for removing the organic solvent in step (c) is 100-150deg.C. The inert gas in step (d) is nitrogen, and the ratio of air to the inert gas is 5:5 by volume. The calcination temperature in step (d) is 400deg.C, and the air and inert gas is supplied in the amount of 10-20LPM by using flow-controlling equipment. The carbon nanotube paste optionally comprises a catalyst selected from a group consisting of Pt, Co, Mn, Zn, Ti and Ni in the amount of 0.1-3% by weight.
