Electrode-forming composition for field emission type of display device, and method using such a composition

A method for constituting an electrode of a field emission type of display device, characterized by having the following steps:

• a step in which the photosensitive copper conductive composition comprising:
• a mixture of
• (a) copper powder at least 70 wt % out of 100 wt % copper powders having a particle size in the range of 0.2-3 μm and
• (b) an inorganic binder with a softening point in the range of 380 to less than 500° C. in an amount of 1-40 wt % based on 100 wt % copper powders,
• said mixture being dispersed in an organic vehicle comprising
• (c) an organic polymer binder,
• (d) a phototoinitiator,
• (e) a photohardenable monomer, and
• an organic solvent;
• and
• the photosensitive copper conductive composition being fireable at a temperature in
• the range of 450-600° C. in a reductive atmosphere is coated as an electrode on an
• underlying layer of dielectric layer formed on a glass substrate,
• a step in which the coated layer is exposed to actinic radiation through a prescribed electrode pattern mask to photopolymerize the exposed part,
• a step in which the development is performed to remove the unexposed part, and
• a step in which sintering is performed based on a sintering profile with the sintering peak temperature around about 500° C. in a reductive atmosphere, in which the oxygen concentration at the temperature range of 300-400° C. for burning out the organic solvent in the aforementioned profile is in the range of 30-1000 ppm and the oxygen concentration at a temperature of 400° C. or higher for sintering the inorganic binder powder and the copper powder is in the range of 10-500 ppm.
