Disclosed is an image pickup device capable of greatly reducing delay in
drive signals supplied to field emission devices, and cross-talk and the
like that originate in these drive signals. The image pickup device
comprises a photoelectric conversion film for receiving incident light on
one side thereof; a field emission layer having an electron emitting
surface apart from and facing the other side of the photoelectric
conversion film, and including a plurality of electron emission devices;
and a drive layer formed on a back side of the field emission layer and
including a plurality of device drive circuits for supplying drive
signals to each of back electrodes of the plurality of electron emission
devices.
