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 form a back surface side of the support member through the
hole at a mask for exposure.
