A process for producing a cold cathode field emission device. A cathode
electrode is formed on a front surface of a support member that transmits
exposure light. An insulating layer is formed on an entire surface. A
gate electrode is formed on the insulating layer. The support member is
irradiated with exposure light from a back surface side of the support
member through the hole as a mask for exposure. An
electron-emitting-portion-forming-layer composed of a photosensitive
material is formed at least inside the opening portion. The support
member is irradiated with exposure light from a back surface side of the
support member through the hole as a mask for exposure.
