The film morphology of screen-printed carbon nanotube emitters was modified by using the liquid phase method, which used ethanol. This liquid treatment modified the surface morphology of the cathode because the organic binder is soluble in ethanol and it removed organic binder from the film. The field emission image uniformity and emission current density were improved without a heat treatment. This technique has showed that the ethanol treatment without the heat treatment provided an ease way to enhanced field emission by surface treatment.
