ELECTRONIC EMITTER AND SOURCE OF ELECTRONS, IMAGE-FORMING APPARATUS AND INFORMATION DISPLAY AND VIEWING DEVICE Russian patent published in 2009 - IPC H01J31/08 H01J1/316 H01J1/53 

FIELD: electrical engineering.

SUBSTANCE: invention is referred to electronic emission, source of electrons where the emission is used, and to the image-forming apparatus. The electronic emitter includes conducting film 1 and 2 located opposite each other on the base plate surface. Such arrangement is intended for generating gap between the ends of the both conducting films. The end of the first conducting film includes a section where minimum distance d1 to the second conducting film is 10 nm or less. Assume that d2 is a minimum distance between the end of conducting film 1 being away from the section, minimum distance dl to the second conducting film, which is 10 nm or less by the minimum distance d1 and the end of second conducting film. The following relation is fulfilled d2/d1≥1.2.

EFFECT: electronic emitter capable of ensuring high effectiveness of electronic emission at high stability.
