Document Type and Number:
WIPO Patent Application WO/2014/170925
Kind Code:
A1
Abstract:
The present invention is an electron emission element that can increase resolution without requiring movable parts, and an image-capturing device provided with said electron emission element. The image-capturing device (1) comprises: an electron emission unit (2) in which a plurality of electron emission sources (23) are arranged in a matrix; a plurality of row-direction electrodes (52) that are arranged so as to be separated from the electron emission unit (2) in the electron emission direction, and that are provided so as to correspond to respective row-direction arrays in the plurality of electron emission sources (23); a plurality of column-direction electrodes (54) that are arranged so as to be separated from the electron emission unit (2) in the electron emission direction, and that are provided so as to correspond to respective column-direction arrays in the plurality of electron emission sources (23); and an electric-field control unit (57) that selectively applies a voltage to the plurality of row-direction electrodes (52) and the plurality of column-direction electrodes (54).
