A plasma display device including: an upper substrate provided with address electrodes; a dielectric material and a fluorescent material coated on the lower surface of the upper substrate; a lower substrate provided with scan electrodes and common electrodes; and a discharge gas of pure He or a gas mixture of more than 99.5 vol % He and the balance of at least one gas selected from the group consisting of Ne, Ar, Kr, Xe and N,, and hermetically sealed between the upper and lower substrates.

Helium plasma display device

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.
