Abstract
A picture display device having a cathode which includes two electric current conductors between which a video signal is applied, for applying a video signal to the cathode to modulate an electron beam emitted from the cathode. To increase the feasible modulation frequency, the inductance of the two electric conductors is reduced by holding one part of the length of the conductors closer together than their spacing over another part of the same length.
