Abstract
An electron emitter composition comprising electron emitting materials, dispersion agent, binder, and pure water is provided. An electron emitter of an FED is produced by the steps of forming a photoresist layer by coating and drying a photoresist composition on an electrode formed on a back plate (cathode plate); exposing and developing the photoresist layer into a predetermined pattern using a mask; forming an electron emitting layer by coating and drying an electron emitter composition consisting of electron emitting materials, a binder, a dispersion agent, and pure water on the developed photoresist layer; exposing the photoresist layer by etching the electron emitting layer; and washing and drying it after stripping the exposed photoresist layer.
