EMITTER COMPOSITION FOR FIELD EMISSION DEVICE, CAPABLE OF MAINTAINING UNIFORM LEVEL OF LIGHT EMISSION BY ADDING DIAMOND AND CARBON NANOTUBES TO EMITTER COMPOSITION, METHOD FOR PRODUCING THE SAME, AND FIELD EMISSION DEVICE USING EMITTER COMPOSITION

摘要

PURPOSE: An emitter composition, a method for producing the same, and a field emission device are provided to maintain a uniform level of light emission even at a low driving voltage, by adding diamond and carbon nanotubes to an emitter composition for a field emission device. CONSTITUTION: An emitter composition comprises carbon nanotubes, binder, glass frit, dispersant, and organic solvent. The emitter composition further includes diamond added to the composition by the content ratio of 0.1 to 20 weight%. A method for producing an emitter composition, comprises a step of injecting carbon nanotubes, binder, glass frit, dispersant, and organic solvent into a container; a step of adding diamond to the composition in the container by the content ratio of 0.1 to 20 weight%; and a step of arranging a stirring unit in the container, and producing a paste by stirring the composition for 1 to 3 hours.
