Abstract
An electron emission device comprises an electron emission electrode with a pointed end and a counter electrode positioned opposite to the pointed end, both formed by fine working of a conductive layer laminated on an insulating substrate.
Claims8
An electron emission device comprising an electron emission electrode with plural pointed ends and a counter electrode positioned opposite to said pointed ends, both formed by fine working of a conductive layer laminated on an insulating substrate, wherein a matrix structure is formed by wirings each having said plural pointed ends and by wirings having counter electrodes respectively corresponding to said pointed ends.
An electron emission device comprising an electron emission electrode having a pointed end and an attracting electrode positioned opposite to said pointed end and having an electron emission aperture, both formed on an insulating substrate in substantially parallel manner to the surface of said substrate, and further comprising selected ones of deflecting electrodes and lens electrodes behind said attracting electrode.
