Abstract
The present invention relates to a flat display screen cathode of the type including, on a substrate, columns of cathode conductors which can be biased individually and associated with a resistive layer on which are deposited electron emission microtips, and including means for canceling a possible lateral electric field between two neighboring columns brought to different potentials.
